SURVIVAIR Opti-Fit™Convertible Facepiece
1
I. INTRODUCTION
This manual provides instructions for the use and main-
tenance of the various respirator operating congura-
tions achievable with the SURVIVAIR Opti-Fit™Convert-
ible full facepiece respirator models 7540, 7640, 7740,
7541, 7641, and 7741. The base conguration of the
SURVIVAIR Opti-Fit facepiece allows use as an air pu-
rifying respirator (APR) in conjunction with S Series par-
ticulate lters, gas and vapor cartridges, and cartridge/
lter combinations as required for specic contaminant
protection. Additional components can be attached to
the SURVIVAIR Opti-Fit Convertible to easily convert it
to a front or side hose connection continuous ow sup-
plied air respirator (CF-SAR) and mask or belt mounted
powered air purifying respirator (PAPR) congurations.
Before using a respirator in a contaminated work
place, you must, at a minimum, understand the ele-
ments of a respirator program, your work place, and
the contaminants you are trying to protect yourself
against. Determining the applicability of a respirator
is difcult. You must be able to calculate the service
life of the cartridges, determine the type and con-
centration of contaminants, and determine whether
the contaminants have poor warning properties,
etc. If you do not have a complete understanding
of the use of respirators, you must seek the aid of
a certied industrial hygienist or contact SPERIAN.
You must read and understand this manual and be
trained in the proper use of the respirator before
wearing it in a contaminated atmosphere.
II. SAFETY PRECAUTIONS
The Warnings, Cautions, and Notes contained in this
instruction sheet have the following signicance
WARNING
Maintenance or operating procedures
and techniques that may result in seri-
ous personal injury, serious personal ill-
ness, or death if not carefully followed.
CAUTION
Maintenance or operating procedures and
techniques that may result in damage to
equipment and/or minor to moderate per-
sonal injury if not carefully followed.
NOTE
Maintenance or operating procedures and
techniques or information considered impor-
tant enough to emphasize.
III. DESCRIPTIONS OF RESPIRATOR OPERATING
CONFIGURATIONS
The SURVIVAIR Opti-Fit full facepiece contains two
connectors on each side of the lens for attaching par-
ticle lters, gas/vapor cartridges or air hoses, as well
as a front adapter for a supplied air breathing hose or
powered air purifying blower. This range of connections
allows the SURVIVAIR Opti-Fit Convertible facepiece
to be congured, through the use of additional compo-
nents, as a supplied air respirator (CF-SAR) or powered
air purifying respirator (PAPR).
The full facepiece is designed with a wide lip silicone
skirt and ve point head strap harness (models 7540,
7640, and 7740). The facepiece is also available with
a Headnet™retention system (models 7541, 7641, and
7741). All facepieces contain a lens treated with an
abrasion resistant coating. The facepiece is available
in three sizes, small, medium and large. While a nose
cup is standard, the facepiece may be equipped with an
optional spectacles kit, clear or tinted lens covers and
neck strap kit.
The connection versatility of the SURVIVAIR Opti-Fit™
Convertible full facepiece and available components and
accessories (see Section VI, Parts List) allow it to be as-
sembled into the following operating congurations:
A. Air Purifying Respirator (APR) Conguration
The side port connectors are used to attach S series
particulate lters, gas and vapor cartridges, and car-
tridge/lter combinations as required for a specic con-
taminant protection. The front adapter can be removed
and replaced with a plug to reduce the front prole of
the mask.
B.Continuous Flow Supplied Air Respirator
(CF-SAR) Conguration
With one side port connector port capped with a sup-
plied screw cap, a high volume, low pressure breath-
ing tube can be attached to the second side connector
to provide a constant ow of air to the facepiece when
connected to an external air source. An alternate con-
nection option uses a breathing tube connected to the
front adapter with both side port connectors capped. An
optional Vortex air cooler may also be connected in-line
to provide cool air to the facepiece.
NOTE
The Vortex air cooler cannot be used in
conjunction with ambient air pump supply
systems.
The SURVIVAIR Opti-Fit™Convertible can also be con-
gured as a CF-SAR with P100 lter cartridges and the
breathing tube connected to the front adapter. When the
air line hose is disconnected from the air line quick cou-
pler, a check valve in the air line couple assembly pre-
vents leakage of contaminated air through the facepiece
hose, and the wearer’s air is drawn through the P100
lters. This feature allows for safe entry, exit or escape
from a dangerous area in case of air supply failure.
For all CF-SAR congurations, when used at pressures
specied in the tables in Section VIII, Part B.8, air is de-
livered to the facepiece at a rate between 115 and 425
liters per minute (4-15 cubic feet per minute [cfm]).

SURVIVAIR Opti-Fit™Convertible Facepiece

WARNING
The pressure within the full facepiece
continuous ow supplied air respirator
(CF-SAR) remains positive under most
working conditions, but as with all respi-
rators, negative pressure excursions are
possible. Conditions when a respirator
can experience negative facepiece pres-
sures include, but are not limited to:
1) the respirator is improperly worn,
2) the respirator is not used in accor-
dance with the instructions, or
3) the respirator is over-breathed during
heavy work rates. The respirator will
provide reduced protection when oper-
ated in a negative pressure mode. Fail-
ure to comply with this warning may re-
sult in personal injury, illness, or death.
The ANSI Z88.2-1992 assigned protection factor (APF)
for full facepiece continuous ow atmosphere supply-
ing respirators is 1000. An APF of 1000 means that this
device, when properly used, will reduce exposure by a
factor of 1000.
C. Powered Air Purifying Respirator (PAPR)
Conguration
The SURVIVAIR Opti-Fit™Convertible full facepiece
can be congured into a mask-mounted or belt-mount-
ed powered air purifying respirator. In the mask-mount-
ed conguration, a high efciency (HE) lter/blower
mounts directly to the nozzle of the facepiece and deliv-
ers air to the facepiece at a ow rate greater than 115
liters per minute (4 cubic feet per minute). The blower
is powered by a belt mounted rechargeable nickel cad-
mium battery pack equipped with an ON/OFF switch.
This conguration is NIOSH approved and SPERIAN
recommended for respiratory protection against dusts,
fumes and mists, including asbestos-containing dusts
and mists, particulate radionuclides, and radon daugh-
ters attached to dusts, fumes and mists.
The belt-mounted PAPR respirator uses the SURVIVAIR
Opti-Fit™Convertible facepiece, a rubber breathing
tube, a belt mounted blower with three (3) cartridges or
lters and a rechargeable Nickel Cadmium (NiCad) bat-
tery pack. Filtered breathing air is provided to the face-
piece at a ow rate greater than 170 liters per minute
(6 cubic feet per minute). To maintain NIOSH approval,
only the equipment and accessories listed on the ap-
propriate NIOSH approval label may be used together.
IV. GENERAL WARNINGS FOR ALL RESPIRATOR
CONFIGURATIONS
The following general warnings must be observed for
proper operation of all air purifying (APR), continuous
ow supplied air (CF-SAR) and powered air purifying
(PAPR) respirator congurations. Additional warnings for
specic operating congurations are listed in Section VIII,
Parts A, B, and C, and must also be observed for proper
operation of the respective respirator conguration.
General Warnings for All Respirator Congurations:
WARNING
● Your employer (or you, if you do not
have an employer) is responsible for
establishing that this respirator is
suitable for the user’s application.
● SPERIAN cannot predict what will
happen to this respirator in every po-
tential environment. Materials can be
chemically attacked if exposed to the
wrong environment and may exhibit
excessive corrosion or other forms
of damage. Permeation or penetration
of gases, liquids or particles through
the materials could be excessive. Ex-
tremes of temperature might cause
thermal degradation. Each of these
things, or a combination of them, could
create conditions in which this respi-
rator would be dangerous to use.
● Before entering a hazardous environ-
ment while wearing this respirator,
you must conduct safe, scientic
tests to determine if the environment
could render the equipment unsafe.
Results of this testing should be well
documented. Seek the help of a certi-
ed safety professional or industrial
hygienist. DO NOT USE this equip-
ment if the user would be endangered
in any way through environmentally
induced degradation of the materials
in the apparatus.
● All persons using this SPERIAN
breathing apparatus must be made
aware of its limitations. We cannot
be responsible for any damage to
property, personal injury, or death in
which environmental exposure is a
contributing factor.
● Do not use this respirator if anything
comes between the facepiece and
your face (e.g., hair, bandanna, head
covering, etc.). This condition will
prevent a good facepiece seal and
may allow the leakage of contami-
nants into the facepiece.
● Do not use this respirator in environ-
ments where the concentrations of con-
taminants are unknown or are immedi-
ately dangerous to life or health (IDLH).
IDLH atmospheres are dened as:
a. Those that the wearer could not
breathe for short periods.
b. Those from which the wearer
could not escape without the aid
of a respirator.
c. Those which have an immediate or
delayed adverse effect on health.
● Do not use this respirator at ambient
temperatures above 130°F (55°C).

SURVIVAIR Opti-Fit™Convertible Facepiece

WARNING─Continued
● Do not wear this respirator if a satis-
factory fit, as determined by a quali-
tative or quantitative fit test, cannot
be obtained. See ANSI Z88.2, latest
issue, and OSHA 29 CFR 1910.134,
latest edition. Beards, stubble, or
sideburns will prevent a good face-
piece seal, and facial hair may inter-
fere with valve function. Do not use
this respirator unless you are clean
shaven. Absence of one or both den-
tures can seriously affect the fit of
the respirator.
● This respirator will reduce, but will
not eliminate the inhalation of con-
taminants. Some sensitive individu-
als may experience health prob-
lems when exposed to even minute
amounts of contaminants. This res-
pirator will not prevent health prob-
lems to those individuals.
● Use of components other than those
listed on the NIOSH approval label
and in this manual, or as authorized
by SPERIAN, or modification of this
respirator in any manner will void
the NIOSH certification and invali-
dates all SPERIAN’s warranties for
the respirator.
● Always read and follow the instruc-
tions listed in the Material Safety
Data Sheet for the chemicals that are
present in the work area.
● Do not use if you have a preexisting
skin condition (for example, folliculi-
tus or vitiligo) until you obtain clear-
ance from a medical doctor.
● This respirator must be worn and
used as specified in SPERIAN’s in-
structions. No respirator can pro-
vide complete protection from all
conditions. Use extreme care for
emergency conditions.
● Some individuals are sensitive to
chemicals (e.g., isocyanates, latex,
oil mists, etc.) or may have some
type of respiratory disorder (e.g.
asthma, chronic obstructive airway
disease, etc.). If you are sensitive to
any chemical or have a respiratory
disorder, you may have a severe reac-
tion at contaminant levels well below
accepted health levels, such as the
OSHA Permissible Exposure Limit
(PEL), ACGIH Threshold Limit Value
(TLV), or the NIOSH Recommended
Exposure Limits (REL). Many chemi-
cals (e.g., isocyanates, Mercury, etc.)
have no physical warning properties
and you cannot taste or smell the
contaminants even though they may
WARNING─Continued
● Do not use this respirator where en-
vironmental conditions could cause
the respirator facepiece to be dis-
lodged or slip.
● Immediately return to a non-contam-
inated area if:
You taste or smell contaminants,a.
or if your eyes, nose, or throat
become irritated.
Breathing becomes difcult.b.
The air you are breathing be-c.
comes uncomfortably warm.
You feel nauseous or dizzy.d.
You notice a loss or decrease ine.
airow.
The facepiece moves, slips, orf.
leaks.
● This respirator does not protect ex-
posed areas of the body. Some con-
taminants can be absorbed directly
through the skin while others may
irritate exposed areas.
● This respirator does not provide pro-
tection from hazardous rays or harm-
ful noise. Always wear proper head
and ear protection.
● This respirator must not be used
underwater, for fumigation, inte-
rior structural fire fighting, abrasive
blasting operations, or in areas where
high heat, sparks, or flames could
contact the respirator. If this respi-
rator will be used during welding, it
is the user’s responsibility to obtain
the proper equipment for protection
against sparks, optical radiation, and
impact. This respirator will not pro-
tect you against these hazards.
● This respirator must be used in con-
junction with a written respirator
program meeting the requirements
of the OSHA Standard for Respira-
tory Protection, 29 CFR 1910.134,
available from the U.S. Department
of Labor, Occupational Safety and
Health Administration. The program
must include procedures for evalu-
ating air contaminants and selecting
appropriate respirators; procedures
for proper use of respirators; proce-
dures for testing the facepiece fit of
respirators; procedures for cleaning,
disinfecting, inspecting, maintaining,
and storing respirators; procedures
for determining if workers are physi-
cally and medically capable of wear-
ing respirators; and procedures for
training employees in the use and
care of respirators and in recogniz-
ing the hazards associated with con-
taminants in the work place.

WARNING─Continued
be present in the respirator face-
piece. This respirator will reduce, but
will not eliminate the possibility of
contaminants entering the facepiece
and causing a severe reaction. Do not
use this respirator until you obtain
clearance from a medical doctor.
● Users must clean and maintain this
respirator only in accordance with
SPERIAN’s instructions. Accessories
not offered by SPERIAN may degrade
performance, and will void NIOSH
certification.
● The respirator facepiece assembly
contains natural rubber latex, which
may cause allergic reactions in some
individuals. Discontinue use if you
experience an allergic reaction.
● Discontinue use if you experience
skin irritation or discoloration.
● This product may provide less than
adequate protection if improperly
used, which may result in personal
injury, illness, or death.
● For use by trained, qualified personnel
only.
● Do not use this respirator if it has
been left exposed in a contaminated
environment as contaminants could
collect on the inside of the facepiece
and be inhaled when the gas mask is
donned.
● Routinely used respirators must be
inspected before and after each use.
Stored emergency respirators must
be inspected after each use and at
least every 30 days. A written record
must be kept of emergency respira-
tor inspections.

B. Continuous Flow Supplied Air Respirator(CF-SAR)
1. Side-mounted Breathing Tube
When using the SURVIVAIR Opti-Fit Convertible
as a supplied air respirator (CF-SAR) with side-
mounted breathing tube, the nozzle adapter and
the side port not in use by the breathing tube
must be capped for proper operation. Attach
the nozzle adapter cap (item 24, P/N 420020)
to the nozzle adapter, making sure to hear an
audible click has the cap is pushed into place
(Figure 1).
If a low prole nozzle setup is desired, the noz-
zle adapter can be removed from the facepiece
and the nozzle plug kit installed in its place. Un-
screw the nozzle adapter from the facepiece by
pressing down on the adapter locking tab from
inside the lens and turning the adapter counter-
clockwise (Figures 2 and 3). Insert the nozzle
gasket (item 25, P/N 763016) into the nozzle
port (Figure 4). Thread in the nozzle plug (item
26, P/N 962066), using a quarter or similar item
in the molded slot to hand-tighten (Figure 5).
Thread one of the provided screw caps (item 27,
P/N 985020) onto the side connector port not
in use by the side-mounted breathing tube and
hand-tighten (Figure 6).
Figure 6. Thread Screw Cap onto Side Connection
Port (CF-SAR and PAPR Only)
2. Front-mounted Breathing Tube and P100
Escape
When using the SURVIVAIR Opti-Fit Convert-
ible as a supplied air respirator (CF-SAR) with
front-mounted breathing tube, both of the side
connector ports must be capped with the includ-
ed screw caps (item 27, P/N 985020). Thread
the screw caps onto the side connector ports
and hand-tighten (Figure 6). If the facepiece
is to be congured as an CF-SAR with P100
escape, the screw caps are not required, and
a P100 lter cartridge (item 38, P/N 105001)
should be screwed onto each side connector
port. Use of the nozzle adapter is necessary
for connecting the breathing tube and therefore
the low-prole nozzle plug kit cannot be used.
C. Powered Air Purifying Respirator (PAPR)
Both the mask-mounted and belt-mounted powered air
purifying respirator (PAPR) congurations require both
side connector ports to be capped with the included screw
caps (item 27, P/N 985020). Thread the screw caps onto
the side connector ports and hand-tighten (Figure 6).
Use of the nozzle adapter is necessary for connecting
the mask-mounted blower or breathing tube and there-
fore the low-prole nozzle plug kit cannot be used.
WARNING
● Do not attempt to use the SURVIVAIR
Opti-Fit Convertible with both the
nozzle adapter and the side connec-
tor ports capped.
● Failure to securely cap unused
threaded side port connectors and/
or the front adapter port for the APR,
CF-SAR or PAPR configuration you
are using can allow contaminants
to leak into the respirator and cause
personal injury, illness, or death.
VIII. OPERATING INSTRUCTIONS FOR SPECIFIC
RESPIRATOR CONFIGURATIONS
A. Air Purifying Respirator (APR) Conguration
In addition to the General Warnings listed in Section IV,
the following warnings apply to air purifying respirator
(APR) congurations:
WARNING
● When using this respirator for protec-
tion against any gas or vapor, includ-
ing gases or vapors with poor warn-
ing properties (e.g., HDI, MDI, or TDI
isocyanates, paint hardeners, etc.),
OSHA 29 CFR 1910.134 requires the
canister to have an end-of-service-
life indicator (ESLI). If the canister
does not have an ESLI, OSHA re-
quires the canister be changed at
intervals derived from a change-out
schedule that is based on objective
information or data that ensures the
canister is changed before the end of
its service life.
● Do not use for protection against
gases or vapors which generate high
heats of reaction with the sorbent
material or against gases or vapors
which are not readily absorbed by
the sorbent (e.g., methanol).
● There are gases and vapors (e.g., ac-
etone, acetaldehyde, etc.) that have a
boiling point below 149ºF (65ºC). Gas
masks should not be used for protec-
tion against these chemicals

SURVIVAIR Opti-Fit™Convertible Facepiece

higher. If the hazard ratio is less than 20, you
may use a full facepiece respirator with a lter
efciency of 95% or higher. If the hazard ratio is
less than 100, you may use a full facepiece res-
pirator with a lter efciency of 99% or higher. If
the hazard ratio is greater than 100, you must
use another type of respirator.
N-series lters must only be used for non-oil
containing aerosols or particulates. R or P-
series lters can be used if the atmosphere
contains oil (e.g., lubricants, cutting uids,
glycerin, etc.). An R-series lter used in an oil-
containing atmosphere must be replaced after
each 8-hour shift. A P-series lter can be used
for more than one 8-hour shift. Please refer to
Section VIII, Part A.6, Chemical and Particulate
Filter Service Life and Replacement, for impor-
tant additional information. Refer to the NIOSH
publication Guide to the Selection and Use of
Particulate Respirators Certied Under 42CFR
84 for additional guidelines on use limitations
for lters.
WARNING
Filters improperly used or improperly
assembled to the facepiece could cause
leakage, which could lead to personal
injury, illness, or death.
c. Cartridge/Filter Installation
Ensure that you have the correct cartridge and/
or lter type for the contaminants in your work
area. If you are not sure, consult your supervi-
sor or safety professional.
Install cartridges and lters by threading i.
them onto the facepiece connectors and
hand tightening. Do not overtighten.
If using lter pads, insert the appropriate ii.
pad into the lter retainer so that the side
stamped with the model number will face
towards the facepiece when installed.
Completely snap the lter retainers onto
the cartridges or lter holders.
Inspect the lter through the retainer to iii.
ensure that the entire edge of the lter is
making contact with the retainer and the
lter is not bunched or folded. The outer
edge of the pad must be compressed be-
tween the top edge of the cartridge or lter
holder and the inner sealing rings of the
retainer. Install lter holders in the same
manner as cartridges.
WARNING─Continued
for more than 8 hours or one shift,
even though the calculated service
life estimate is greater that 8 hours or
one shift. These contaminants can mi-
grate through the canister even when
the canister is not in use (e.g., over-
night) and collect in the facepiece.
● Do not use this respirator without the
appropriate SPERIAN cartridges and/
or lters securely attached onto the
facepiece. Always read cartridge la-
bels prior to use and be certain that
you have cartridges and/or lters
that will provide the required protec-
tion. This respirator must be used
for protection against only those air
contaminants listed on the air purify-
ing cartridge, lter and/or the NIOSH
approval label. Respirators labeled
for protection against particulates
only shall not be used for gases/va-
pors. Respirators labeled for protec-
tion against gases/vapors only shall
not be used for particulates.
● This respirator does not supply ox-
ygen. Do not use the respirator in
atmospheres containing less than
19.5% oxygen by volume.
● Failure to comply with this warning
may lead to personal injury, illness,
or death.
1. Installing Chemical Cartridges and Particulate
Filters
a. Mercury Vapor Cartridges
Special or Critical User’s Instructions: The mer-
cury vapor cartridges incorporate passive end-
of-service-life indicators (ESLI). Each ESLI,
yellow in color when new, turns gray when
exposed to mercury vapor. Do no use these
cartridges unless you can distinguish between
the safe and discard colors of the ESLI. The
indicators must be visible when wearing the
respirator without having to manipulate either
the facepiece or the indicator. If the indicators
cannot be seen, do not wear the respirator. The
cartridges must be replaced when the ESLI
change color from yellow to gray, when the
ESLI become dirty or damaged, after 30 days
of use, or if removed from their original packag-
ing and not used within 30 days. Never enter
or remain in a hazardous atmosphere if one or
more of the ESLI is gray.
b. Particulate Filters
Before using a particulate lter, you must con-
rm the atmosphere is non-IDLH and not oxy-
gen decient, the contaminant is a particulate
hazard, and you must determine the hazard ra-
tio (hazard concentration/exposure limit). If the
hazard ratio is less than 10, you may use a half
mask respirator with a lter efciency of 95% or

SURVIVAIR Opti-Fit™Convertible Facepiece

2. Donning Instructions for APR Conguration
WARNING
● Your employer (or you, if you do not
have an employer) is responsible for
establishing that this respirator is
suitable for the user’s application.
● Always read cartridge labels prior to
use to be certain that you have car-
tridges and/or lters that will provide
the required protection. Filters la-
beled for protection against particu-
lates only shall not be used for gas-
es/vapors, and cartridges labeled for
protection against gases/vapors only
shall not be used for particulates.
Both cartridges/lters must be of the
same type.
● Ensure that the o-ring (Item 23, P/N
824014), is in the cap (Item 24, P/N
420020) and the cap plug is securely
seated on the adapter. If the nozzle
plug (Item 26, P/N 962066) is to be
used instead of the cap, be sure
that the Nozzle Gasket (Item 25, P/N
763016) is installed with an inhala-
tion valve.
● The failure to comply with this warn-
ing may lead to personal injury, ill-
ness, or death.
1. Inspect the respirator as described in Section
IX, Part B.
2. Verify that unused ports are capped as detailed in
Section VII for the APR operational conguration.
3. Verify that two lters and/or cartridges are at-
tached to the threaded side connectors of the
facepiece.
4. Adjust the top straps until one inch of strap ex-
tends through each buckle. Fully loosen the
lower straps. For respirators featuring a Head-
net, fully loosen all straps.
5. Place the neck strap (if installed) over your head.
6. Place your chin against the chin cup and center
the facepiece on your face. See Figure 7.
Figure 7. Place Chin in Chin Cup
7. Hold the facepiece against your face and pull
the straps over your head.
8. Tighten the two lower straps, temple straps, then
the top straps until a good seal is obtained and
all straps lie at on your head. Do not overtight-
en the straps. See Figure 8a. For respirators
with a Headnet, tighten the two lower straps and
the temple straps until a good seal is obtained
and all straps lie at on your head. Flatten the
Headnet with a wiping motion toward the back
of your head. See Figure 8b. Retighten straps
as necessary. Do not overtighten.
Figure 8a. Adjust Lower Straps First
Figure 8b. Flatten Headnet with Wiping Motion
NOTE
When properly adjusted, the head strap hub
should be centered on the back of your head
and the lower straps should be below your
ears. See Figure 9a. For the Headnet ver-
sion, the backstrap should be at the nape of
the neck. The Headnet should lie at on the
head and not bunch up. See Figure 9b.

3. Fit Check Instructions for APR Conguration
You must perform the following t check each time
the respirator is worn or before entering the contami-
nated area.
WARNING
If a leak-tight seal is not obtained during
the following t check, do not wear the
respirator. Ask your supervisor or safety
professional for assistance. The failure
to comply with this warning may lead to
personal injury, illness, or death.
Negative Pressure Fit Check
Cover the inlet of the cartridges and/or lters with the
palms of your hands or another suitable item, such
as a thin sheet of plastic or rubber. When the respi-
rator is equipped with cartridges, lter retainers may
be used as an aid. Alternatively, the cartridges may
be removed to perform the t check. If removed,
SPERIAN recommends someone other than you
reinstall them after a leak-tight t is achieved. It
is difcult for the wearer to reinstall the cartridges
without disturbing the face seal and to determine
whether the cartridges are correctly seated against
the facepiece. It is your responsibility to ensure that
the face seal is not disturbed when reinstalling the
cartridges and that each cartridge is sealed against
the facepiece.
Inhale gently and hold your breath to slightly collapse
the facepiece. If air leakage occurs, readjust the
facepiece and head strap, then retest. If lter retain-
ers are used, do not remove them after the t check
is completed. Removing the lter retainers may shift
the facepiece and break the face seal.
4. How to Use the Respirator
To receive the maximum protection available from
your respirator, you must read, understand, and
follow all the warnings, limitations, and instructions
contained in this manual and follow your employer’s
instructions on the use and maintenance of the res-
pirator. Read and understand the following warnings
prior to using the respirator.
WARNING
● Never remove the respirator for any
reason while in the work area.
● You must leave the work area imme-
diately if the facepiece-to-face seal is
disturbed for any reason such as:
a. Slippage due to sweating or ex-
cessive head movement.
b. The facepiece becomes dislodged
as a result of being knocked.
c. Sneezing or coughing while wear-
ing the facepiece.
d. You need to blow your nose,
scratch your face or adjust your
spectacles.
● For any other reason that would cause
the facepiece seal to be disturbed.
● You must restore the facepiece-to-
face seal and perform a fit check in
a non-hazardous environment before
re-entering the work area.
● Failure to comply with this warning
may lead to personal injury, illness,
or death.
5. Dofng Instructions for APR Conguration
1. Loosen the two lower head straps completely
(for ve strap head harness or Headnet).
2. Grasp the nozzle rmly, and pull the facepiece
upward over the head.

SURVIVAIR Opti-Fit™Convertible Facepiece

WARNING
● OSHA allows the use of air purify-
ing respirators for protection against
contaminants with poor warning
properties. You must replace car-
tridges when the end-of-service-life
indicator (ESLI) has changed color
or in accordance with an OSHA com-
pliant cartridge change-out schedule
that is based on objective information
or data that ensures the cartridges
are changed before the end of their
service life.
● You must immediately leave the con-
taminated area if you taste or smell
contaminants, or if your eyes or
throat become irritated. Replace car-
tridges and/or filters before re-enter-
ing the contaminated area.
● Establishing the cartridge service
life for mixtures of contaminants is a
complex task, and one that requires
considerable professional judgment
to create a reasonable change-out
schedule. OSHA provides a “rule-of-
thumb” method for determining the
cartridge service life for mixtures.
The method addresses two situa-
tions. The first is where the individual
compounds of the mixture have simi-
lar breakthrough times (i.e., within
one order of magnitude). In this case,
OSHA recommends adding the con-
centrations of all the components of
the mixture to determine a “total con-
centration,” then determine the mix-
ture service life by applying the total
concentration to the component with
the shortest service life. The second
is where the individual compounds
have breakthrough times that vary
by two orders of magnitude or great-
er. In this case, OSHA recommends
the mixture service life be based
on the contaminant with the short-
est breakthrough time. The OSHA
rule-of-thumb methods may not be
applicable for all mixtures. In some
cases, the actual mixture service life
may be much lower than the one cal-
culated. For this reason, SPERIAN
recommends that the cartridge ser-
vice life for mixtures be determined
using experimental methods. If you
are unsure of how to determine the
cartridge service life for mixtures,
please contact SPERIAN.
● Failure to comply with this warning
may lead to personal injury, illness,
or death.
The cartridge service life depends on the user’s
breathing rate, the characteristics of the contami-
nant, and the environmental conditions such as
temperature and humidity. Saturated cartridges will
leak trace amounts of contaminant to the wearer,
which may be detected by odor, taste, and/or ir-
ritation. Replace cartridges when the end-of-ser-
vice-life indicator (ESLI) has changed color, at the
rst trace of the characteristic contaminant odor
or taste, at regularly scheduled intervals recom-
mended by your safety professional, if they show
any signs of damage, or in accordance with an
OSHA compliant cartridge change-out schedule.
The service life of the cartridge can be estimated
using SPERIAN’s cartridge service life estimation
program, available from SPERIAN. Always replace
cartridges in pairs.
Replace cartridges as follows:
1. Return to fresh air.
2.Remove cartridges by turning counter-
clockwise. Dispose of used cartridges
in accordance with Federal, state, and
local guidelines.
3.Install new cartridges, taken only from
sealed packages, as described in Sec-
tion VIII, Part A.1.C.
4. Perform a facepiece t check as de-
scribed in Section VIII, Part A.3.
b. Particulate Filter Service Life and Replacement
WARNING
You must replace the lters when breath-
ing becomes uncomfortable or difcult.
As particulates collect on the lter sur-
face, the breathing resistance of the
facepiece increases. If you wait too long
to replace the lters, the particulates
may leak past the face seal instead of
being collected on the lters. Therefore,
SPERIAN strongly recommends that the
lters be changed at least daily.
Failure to comply with this warning
may lead to personal injury, illness, or
death.
The service life of the lter depends on the lter
series, the way in which the lter captures the con-
taminant (either mechanically or by electrostatic
means), the characteristics of the contaminant,
the user’s breathing rate, and the environmental
conditions such as humidity, temperature, etc.
SPERIAN’s N95, N99, R95 and Slimline P100 l-
ters use electrostatic charges to capture particles.
High humidity and temperatures, as well as con-
tact with oil or non-oil based liquid aerosols, may
affect the capture of contaminants by these lters.
All new SPERIAN lters must be maintained in fac-
tory sealed bags and must only be removed when

SURVIVAIR Opti-Fit™Convertible Facepiece
15
they are to be used. Used lters must be stored in
a protective bag, and in a clean, dry environment.
Detailed guidelines for each lter series are pro-
vided below.
1. N-Series Filters
These lters are only NIOSH approved for use
against solid and water-based particulates
and must not be used in any area that con-
tains oil aerosols. N-series lters capture par-
ticles using electrostatic charges, and these
types of lters may be subject to some loss of
efciency if they are exposed to certain liquid
aerosols. The N-series (N95 and N99) lters
must be replaced immediately whenever:
● they are damaged, soiled, soaked with
liquids such as water or alcohol, or ap-
pear to be suspect or damaged in any
manner, or
● the user notices an increase in breathing
resistance such that the respirator be-
comes uncomfortable to wear.
If none of the above occurs and there is a
respiratory protection program per OSHA
29 CFR 1910.134 in place, then these lters
may be used continually, but only for a maxi-
mum of 30 days or 40 total hours, whichever
comes rst. However, SPERIAN recommends
that all lters be replaced daily because the
user may be unable to detect small defects
resulting in a loss of lter efciency, and the
determination of when breathing resistance
becomes too uncomfortable is subjective.
Further, SPERIAN recommends that these
lters be replaced daily when there are any
liquid aerosols present and there is no respi-
rator program in place.
2. R-Series Filters
These lters are NIOSH approved for use
against any type of particulate, except that
for atmospheres that contain oil. The lters
can only be used for 8 hours or a single shift,
whichever comes rst. When used in either
oil-containing or non-oil containing atmo-
spheres, these lters must be replaced im-
mediately whenever:
● they are damaged, soiled, soaked with liq-
uids such as water or alcohol, or appear to
be suspect or damaged in any manner, or
● the user notices an increase in breathing re-
sistance such that the respirator becomes
uncomfortable to wear.
If none of the above occurs, the lter is used
in an area that does not contain oil, and there
is a respiratory protection program per OSHA
29 CFR 1910.134 in place, then these lters
may be used continually, but only for a maxi-
mum of 30 days or 40 total hours, whichever
comes rst. Even when used in non-oil con-
taining atmospheres, SPERIAN recommends
that all lters be replaced daily because the
user may be unable to detect small defects
resulting in a loss of lter efciency, and the
determination of when breathing resistance
becomes too uncomfortable is subjective.
3. P-Series Filters
These lters are NIOSH approved for long
duration use against any type of particulate.
When used in either oil-containing or non-oil
containing atmospheres, these lters must be
replaced immediately whenever:
●they are damaged, soiled, soaked with
liquids such as water or alcohol, or ap-
pear to be suspect or damaged in any
manner, or
● the user notices an increase in breathing
resistance such that the respirator be-
comes uncomfortable to wear.
If none of the above occurs and there is a
respiratory protection program per OSHA
29 CFR 1910.134 in place, then these lters
may be used continually, but only for a maxi-
mum of 30 days or 40 total hours, whichever
comes rst. However, service time for the
Model 1050 P100 lter can be extended if l-
ter performance to 42 CFR Part 84 can be
demonstrated. Whether used in oil-containing
or non-oil containing atmospheres, SPERIAN
recommends that all lters be replaced daily
because the user may be unable to detect
small defects resulting in a loss of lter ef-
ciency, and the determination of when breath-
ing resistance becomes too uncomfortable is
subjective.
WARNING
Failure to properly assemble lter pads
to cartridges or lter holders can cause
leakage, which could lead to personal
injury, illness or death.
1. Return to fresh air.
2. Remove cartridges or P100 lters by
turning them counterclockwise. Dispose
of used cartridges and lters in accor-
dance with Federal, state, and local
guidelines.
3. If using lter pads, remove the lter re-
tainers from the cartridges or lter hold-
ers. Remove the used lter pads and
dispose of them in accordance with Fed-
eral, state, and local guidelines. Clean
the lter retainer and cartridge or holder
if necessary.
4. Install new P100 lters or lter pads,
taken only from sealed packages, as
described in Section VIII, Part A.1.C.
5. Perform a facepiece t check as de-
scribed in Section VIII, Part A.3.

B. Supplied Air Respirator (CF-SAR) Congurations
In addition to the General Warnings listed in Section IV,
the following warnings apply to supplied air respirator
(CF-SAR) congurations:
WARNING
● SPERIAN respirators, accessories,
and associated equipment should
not be used in atmospheres that
may contain contaminant concentra-
tions above the lower explosive level
(LEL). Intrinsic safety certification
of electronic components does not
eliminate potential danger from igni-
tion in these atmospheres.
● Do not exceed maximum use con-
centrations established by regula-
tory standards.
● Air line respirators can be used only
when the respirators are supplied
with respirable air meeting the re-
quirements of CGA-7.1, Grade D or
higher quality.
● Use only the pressure ranges and
hose lengths specified in these user
instructions.
● Do not use this respirator in confined
spaces.
● For the P100 escape configuration:
Never use this respirator without two
SPERIAN Model 1050 P100 filters se-
curely threaded onto the facepiece.
● For the P100 escape configuration:
The P100 escape filter functionality
of the P100 escape CF-CF-SAR con-
figuration is not to be used in atmo-
spheres containing less than 19.5%
oxygen.
● FAILURE TO COMPLY WITH THIS
WARNING MAY LEAD TO PERSONAL
INJURY, ILLNESS, OR DEATH.
1. Air Supply (applicable to side-mounted tube, front-
mounted tube and P100 escape congurations)
The following warnings regarding air supply are ap-
plicable to all continuous ow supplied air respirator
(CF-SAR) congurations (side-mounted tube, front-
mounted tube, P100 escape), and should be fol-
lowed for safe operation of a supplied air respirator.
WARNING
● Compressors, storage cylinders,
valves, regulators, fittings, and oth-
er hardware must be large enough
to deliver the air volume required by
all users at peak demand.
● You are responsible for air quality and
compliance with safety and health
codes applicable to your area.
● See the tables in Section VIII, Part B.8
for hose length, air supply pressure,
and quick coupler requirements.
● Do not mix hose types or coupler as-
semblies except as specified in the
tables in Section VIII, Part B.8.
● Be sure that all respirable air system
piping, tubing, fittings, and couplings
are incompatible with non-respirable
gas systems.
● If an air pump or compressor is used
to supply breathing air, the following
precautions must be taken:
The air pump or compressor in-1.
take must not be located in an area
that could possibly contain con-
taminants, such as but not limited
to engine exhaust, spray booth
exhaust, or other toxic gases.
The air pump or compressor must2.
have intake and exhaust filters
capable of removing dirt, carbon
dust, oil, oil vapor, and excess
water mist that may be present in
the area of the intake or may be
generated within the air pump or
compressor itself. Carbon monox-
ide alarms should be installed on
oil lubricated compressors and in
any other situation where carbon
monoxide may be present.
Frequently test the purity of the air3.
delivered by the air pump or com-
pressor. Air pumps and compres-
sors deteriorate with age, as does
the quality of the air they deliver.
Set the pressure regulator and/or4.
relief valve to maintain the pres-
sure within the range specified in
the tables in Section VIII, Part B.8.
● FAILURE TO COMPLY WITH THIS
WARNING MAY LEAD TO PERSONAL
INJURY, ILLNESS, OR DEATH.
Ensure that the air supply is type 1, Grade D or bet-
ter, as described in the Compressed Gas Association
Commodity Specication for Air, G-7.1.
Set relief valves at a maximum pressure of 150 psig
(1.03 Mpa).

2. Quick Coupler Assembly (applicable to side-
mounted tube, front-mounted tube and P100 es-
cape congurations)
A male plug from one of the air line coupler kits
listed in the Parts List, Section VI, must be assem-
bled to the open end of the breathing tube. This
operation requires a torque wrench.
WARNING
Do not use pipe thread sealing tape
on the quick coupler or air line hose
threads. The tape could restrict air-
ow or tape fragments could enter the
air system. Failure to comply with this
warning may lead to personal injury, ill-
ness, or death.
The steps and considerations required for com-
pleting the Quick Coupler assembly are as follow:
1. Breathing Tube
a. Apply Loctite No. 567 PST pipe sealant
or equivalent to the ¼ NPT threads of the
male quick coupler plug. Ensure that no
sealant enters the quick coupler or air line
hose.
b. Thread the male plug into the female t-
ting on the breathing tube. Torque to 150
±5 in-lb.
WARNING
● The full facepiece is NIOSH approved
only when supplied with respirable
breathing air through no more than
three (3) lengths of 9308 Series hose,
or two (2) lengths of 9852 Series air
line hose at the pressures listed in
Tables I and II, located in Section VIII,
Part B.8. Do not mix hose types from
different columns.
● The third pressure column in Table
I should be used when using a low
pressure ambient air pump. No more
than two (2) lengths of 9852 Series
air line hose may be used. The air
supply must be coupled to the air
source and the breathing tube with
the OBAC couplers and plugs.
● FAILURE TO COMPLY WITH THIS
WARNING MAY LEAD TO PERSONAL
INJURY, ILLNESS, OR DEATH.
CAUTION
Do not exceed the maximum continuous
duty or maximum intermittent duty operat-
ing pressure of the low pressure ambient air
pump. Refer to your pump user manual.
NOTE
The Vortex air cooler is not approved for use
with the low pressure ambient air pump.
2. Air Supply Hose
Each length of hose is equipped with a ¼ inch
female NPT swivel nut at each end and a male
to male ¼ inch NPT adapter. The male to male
adapter may be used to connect two lengths of
hose or connect the hose to the air supply. Four
approved methods of connecting hose lengths
and air supply are illustrated in Figure 10.
Figure 10. Methods of Hose Connection
3. When assembling the quick disconnect ttings
of the coupler or the male to male adapters to
the hose, verify that the hose gaskets are in
place and torque to 90 ±5 in-lb. Thread sealant
is not required.
4. The air supply connection using the ¼ inch male
to male adapter illustrated in Method 2 is also
approved for use with Methods 3 and 4.
●Method 1 is preferred when only one length
of hose is required since it allows the hose to
be disconnected from the air supply.
●Method 3 is preferred when multiple lengths
of hose (maximum of three) are required,
eliminating the cost of quick disconnect cou-
plers at the hose junctions.
5. Pressurize and check for leaks with a bubble
type leak detector. If leaks are detected:
●Disassemble and repeat steps 3 through 5.
● If the leaks persist, remove the hose from ser-
vice and have repairs made by a SPERIAN
certied technician.
●Disassemble and repeat steps 3 through 5.
●If the leaks persist, remove the hose from ser-
vice and have repairs made by a SPERIAN
certied technician.
