LIMITATIONS
The OptimAir MM 2K with OptiFilter
Type HE filter cartridge, or Type HE par-
ticulate filter, are approved as high effi-
ciency particulate air filter for powered
air-purifying respirators. Filter does not
remove gases or vapors from the air
supply. No filter is designed for all sub-
stances, Therefore, you must know
what the contaminant is, as well as its
concentration, before selecting a respi-
rator. This respirator does not supply
oxygen. Do not use this respirator
unless the surrounding air contains a
minimum of 19.5 percent oxygen. The
respirator may be used at temperatures
between 0°F and 120°F, and may be
worn under flame-retardant garments. If
used below 40°F, a fully-charged bat-
tery may not operate the motor-blower
for an entire shift.
RESPIRATOR USE LIMITATION
The wearer must comply with the fol-
lowing MSA respirator use limitations:
1. Maximum Use Concentration – Do
not exceed any of the following:
a. 1000 times the exposure limit for
the contaminants present.
b. Immediately dangerous to life or
health (IDLH) concentration for
any contaminant present.
2. The limitations outlined in the appli-
cable NIOSH approval.
3. Any applicable limitation contained
in a standard established by a regu-
latory agency (such as OSHA) with
jurisdiction over the wearer.
4. NIOSH allows this respirator to be
used for protection against a mix-

INTRODUCTION
ture of particulates that are present
simultaneously or alternately
against one particulate then anoth-
er (using the same filter) if the mix-
ture meets the following condi-
tions:
a. The filter must be approved for
all particulate.
b. Particulates (dusts, mists,
fumes, asbestos, radionuclides)
can be mixed with any other
particulate for which the filter is
approved.
c. Contaminants present simulta-
neously must be below IDLH
levels for the specific contami-
nants. If any one contaminant in
the mixture exceeds the IDLH
concentration then the entire
mixture must be treated as IDLH
and the respirator cannot be
used (except for escape).
1. This device does NOT supply
oxygen. Use only in adequately
ventilated areas containing at
least 19.5 percent oxygen.
2. This respirator must be used in
conjunction with proper chemi-
cal or particulate cartridges for
protection against specific con-
taminants.
3. Do not use when concentrations
of contaminants are unknown or
immediately dangerous to life or
health (IDLH). (See the respirator
NIOSH approval plate P/N
818105 to determine if this
device can be used for escape
from those concentrations.)
4. Do not use when appropriate
exposure limit (OSHA, PEL,
NIOSH REL, ACGIH TLV, etc.) is
not known or when it is below
the odor threshold or any other
established warning level for the
contaminant.
5. Leave area immediately if
A.Breathing becomes difficult.
B.Dizziness or other distress
occurs.
C. You taste or smell contami-
nant.
D. You experience eye, nose or
throat irritation.
6. Use strictly in accordance with
instructions, labels and limita-
tions pertaining to this device.
7. This respirator may not provide
a satisfactory seal with certain
facial characteristics, such as
beards or large sideburns, that
prevent direct contact between
the skin and the sealing surface
of the facepiece. Do not use this
respirator if such conditions
exist.
8. Never alter or modify this device.
9. This respirator is for use by
trained and qualified personnel
only.
FAILURE TO FOLLOW THE ABOVE
WARNINGS CAN RESULT IN SERI-
OUS PERSONAL INJURY OR
DEATH.
• This respirator/filter provides
LIMITED protection. It may help
reduce exposure to airborne bio-
logical agents, including H1N1
(swine) flu virus, avian (bird) flu
virus, other types of influenza,
SARS, or other bacterial or viral
4

TAL 0110 (L) Rev. 8 - 10020949
INTRODUCTION
biological agents and help reduce
the risk for influenza infection
during a pandemic, but will NOT
eliminate the risk of exposure,
infection, illness, or death.
• This respirator/filter is certified by
NIOSH to comply with the
requirements specified for the
designated filter efficiency level;
however, appropriate authorities
have NOT established a safe level
of exposure to biological agents.
Therefore, the respirator may
NOT prevent transmission of
influenza virus.
• Refer to the Centers for Disease
Control and Prevention (CDC) at
www.cdc.gov for guidance on the
use of respirators to help
decrease exposure to H1N1 virus
or other airborne biological
agents in community, home, and
occupational settings. The CDC
recommends fit testing, medical
evaluations, and training for opti-
mal effectiveness when a respira-
tor is used in a non-occupational
setting. Neglecting these
preparatory measures may cause
an unsafe condition. Respirators
used in an occupational setting
MUST be used in accordance
with a complete respiratory pro-
tection program as required by
OSHA, which includes proper
selection, training, fit-testing, and
fit-checking. Detailed information
on a respiratory protection pro-
gram is available by contacting
OSHA or visiting www.osha.gov.
• Do NOT remove respirator in con-
taminated areas. The outer sur-
face of the respirator MUST be
treated as if it is contaminated at
all times. Tight-fitting safety gog-
gles, or a full-facepiece respira-
tor, may further help prevent
transmission of influenza virus.
• The CDC recommends frequent
hand washing and wearing gloves
to help prevent transmission of
disease due to exposure to sur-
faces where contaminants may
be present, and also immediately
following removal of the respira-
tor.
• Do NOT reuse or share mainte-
nance-free respirators. ALWAYS
clean cartridge-style respirators
before reuse in accordance with
the instructions provided.
• This respirator/filter is NOT for
use by (a) children, or (b) people
with a medical condition that may
be adversely affected by using it.
Failure to follow all warnings and
instructions can result in serious per-
sonal injury or death.

DESCRIPTION
DESCRIPTION
The OptimAir MM 2K Mask-Mounted
Powered Air-Purifying Respirator
(PAPR) from MSA is certified by the
National Institute for Occupational
Safety and Health (NIOSH) as an air-
purifying device designed only for use
in atmospheres NOT immediately dan-
gerous to life or health (IDLH).
The OptimAir MM 2K is used with the
Facepiece, which is available in small,
medium or large sizes. If needed,
Advantage®4100, Ultravue®and Ultra
Elite®facepieces may be equipped with
an integral welder’s lens or clip-on
welder’s adapter (only used with
Ultravue facepieces). See
Accessories/Spare Parts.
The motor-blower and replaceable
high-efficiency filter are worn as an
assembly attached to the facepiece.
The rechargeable battery pack is worn
on the support belt. A power cable
connects the belt-mounted battery
pack to the motor-blower on the face-
piece. A battery charger is supplied
with the respirator.
PRINCIPLE OF OPERATION
The motor-blower draws surrounding
air through the filter which captures the
particulate contaminant. Filtered air
passes through to the facepiece and
creates higher pressure than the sur-
rounding atmosphere. Therefore, if a
leak occurs, air will flow from inside the
facepiece to the outside air. This is
referred to as positive pressure. Air flow
also provides wearer comfort.
The rechargeable NiMH battery pack
supplies 4.8 volts (nominal) to the
motor-blower. The battery pack is
replaceable. A fully charged battery is
designed to operate in excess of 8
hours. Then the battery pack can be re-
charged in 3 hours using the standard
charger.
The replaceable filter cartridge which
traps the particulate contaminant is at
least 99.97% efficient against 0.3
micron DOP aerosol.
RESPIRATOR FIT TEST
A qualitative or quantitative respirator fit
test should be carried out for each
wearer of this respirator to determine
the amount of protection it will provide.
Respirator fit tests are explained fully in
the American National Standard for
Respiratory Protection, ANSI Z88.2,
which is published by the American
National Standards Institute, 11 West
42nd Street, New York, New York
10036.
Quantitative Test — If a quantitative fit
test is used, a fit factor that is at least
100 shall be obtained before that respi-
rator is assigned to an individual.
Qualitative Test — If a qualitative fit
test is used, only validated protocols
are acceptable. The individual must
pass a test designed to assess a fit fac-
tor of at least 100.
Powered Air-Purifying Respirators must
be qualitatively or quantitatively fit test-

respirator in the powered air-purifying
mode operation.
EXPOSURE LIMITS
A listing of acceptable exposure limits
from the following sources:
• American Conference of
Governmental Industrial Hygienists
(ACGIH)
• Occupational Safety and Health
Administration (OSHA)
• National Institute for Occupational
Safety and Health (NIOSH)
• American Industrial Hygiene
Association (AIHA)
Contact MSA at 1-800-MSA-2222 for
information.
Exposure Limits for Mixtures
The American Conference of Govern-
mental Industrial Hygienists (ACGIH)
publishes the following information to
determine the TLV of a mixture.
First determine the total concentration
of the chemical mixture (CMixture) from
the individual contaminant concentra-
tions (C1, C2, C3,…) using the following
formula:
CMixture = C1+ C2+ C3+ …
The TLV of the mixture is found by
using the following formula where T1,
T2, T3,… are the individual contaminant
TLVs and C1, C2, C3,… are the individ-
ual contaminant concentrations:
Only use these equations if the contam-
inants present are actually mixed. Some
substances do not mix and may be
present separately, for example, in
pockets or at different levels. In that
case, the lowest TLV of the substances
present must be used to determine the
appropriate respirator category for pro-
tection against all contaminants pres-
ent.

CHARGING THE BATTERY PACK
UNPACKING & INSPECTION
The OptimAir MM 2K consists of the
following components:
motor-blower
battery pack
support belt
charger
cable
facepiece
storage plug
filter
Thoroughly inspect all components
of the respirator before the device is
used. Read and observe all NIOSH
approval limitations as they apply to
using the OptimAir MM 2K.
Do not drop the OptimAir MM 2K.
The battery pack can be damaged by
impact. The case can be cracked and
could allow water into the pack. If
the unit is dropped, inspect the case
for cracks. If the motor blower no
longer operates from the compro-
mised battery pack, the battery pack
must be replaced.
The motor-blower housing can be
damaged by impact. The blower
impeller can be loosened or the
motor shaft can be bent. If the unit is
dropped, check the case for cracks.
Listen closely to the sound of the
motor. If the impeller binds or rattles,
or if air output is reduced, the entire
motor-blower must be replaced.
CHARGING THE BATTERY PACK
The battery pack must be fully charged
before the respirator is first used. Use
only the P/N 10023483 battery charger
from MSA. Other chargers can damage
the battery due to internal wiring differ-
ences or incorrect charging rates.
The battery pack should be stored at a
temperature range of 50°F to 85°F. If
the battery pack has been stored in a
“fully charged” condition for more than
one week, the battery pack should be
charged until a full charge is indicated.
Do not charge the battery pack
where there are explosive concentra-
tions of combustible gases, vapors,
or mists. An explosion or fire can
result. Replace the charger if the
cord is damaged or worn, or if the
case is cracked or distorted. Do not
use a damaged charger. Doing so can
result in serious personal injury or
death, or create a fire hazard.
1. Line up the key in
the charger cable
plug with the slot
in the female con-
nector on the bat-
tery pack.

CHARGING THE BATTERY PACK
2. Push the plug into the female con-
nector and turn the ring _ turn to
secure it.
3. Plug the charger into a 115-120 V,
50, 60 Hz (standard AC) outlet. The
charger can be used internationally
with the appropriate adapter.
Voltages lower than 115V are not rec-
ommended. Voltages greater than
120V will damage the battery charger
and battery pack.
4. Charge the battery pack until a full
charge is indicated.
The charger uses one LED. When the
battery is charging, the LED will be
Red. When the LED is Green the bat-
tery is fully charged. The battery can
stay connected to the charger until it is
needed. If the LED is Amber, the bat-
tery is not at the proper temperature.
The charging will start when the battery
pack reaches the optimum charging
temperature of 35°F to 100°F. If the
LED is flashing Red, there is a failure.
Disconnect battery pack, and unplug
charger. Plug charger back into outlet
and reconnect battery pack to reset
charger. If LED flashes Red during any
part of the charge, after it has been
reset, remove the battery from service.

ASSEMBLING THE MASK-
MOUNTED RESPIRATOR
1. If necessary,
remove the cou-
pling nut from the
facepiece inhala-
tion housing. The
coupling nut may
be used if the
facepiece is used on MSA respira-
tors. Check that the inhalation check
valve and spider gasket are in the
facepiece inhalation housing. The
gasket is needed so that the face-
piece and motor-blower will seal.
2. Thread the motor-
blower coupling
nut into the face-
piece until resist-
ance is encoun-
tered. Continue
tightening the
coupling nut an additional 60

es on the coupling nut) into the
facepiece.
3. If attached, unthread the filter from
the motor-blower assembly.
4. Check that there
is a gasket in the
motor-blower
housing. The gas-
ket is necessary
so that the filter
and motor-blower
will seal.
Do not use the respirator if the spi-
der gasket in the facepiece inhala-
tion housing or the gasket in the
motor-blower housing is missing or
appears damaged. Failure to follow
this warning will permit the contami-
nant to be drawn into the respirator
and inhaled, resulting in serious res-
piratory injury or death.
5. Thread the filter
into the motor
blower and hand-
tighten.
6. Line up the key on
the battery cable

To test facepieces for leakage using a
negative pressure method:
1. Block the filter
opening.
15

TAL 0110 (L) Rev. 8 - 10020949
USING THE RESPIRATOR
2. Inhale so that the
facepiece collaps-
es against your
face. Hold your
breath for 10 sec-
onds. The face-
piece should
remain collapsed.
3. If the facepiece does not remain
collapsed, readjust the headstraps
and repeat steps 1 and 2.
4. If you cannot get a seal by adjusting
the headstraps, check the facepiece
for leaks. See Maintaining the
Respirator. Locate the problem and
correct it before using the respirator.
Leave the area immediately if any of
the following symptoms occur
• breathing becomes difficult
• dizziness or other distress occurs
• you taste or smell the contaminant
• you experience eye, nose or throat
irritation.
If you bump or impact the cartridges,
leave area immediately and check
the security of the cartridge. Perform
an Air Tightness Test before re-entry.
This device may not seal properly
with your face if you have a mous-
tache, beard, gross sideburns or
other physical characteristics that
interfere with the face-to-facepiece
seal (see ANSI Z88.2). If the face-
piece does not seal against your
face, non-respirable air can leak into
the facepiece, reducing or eliminat-
ing the protection. The face-to-face-
piece seal must be tested before
each use. DO NOT USE A FACE-
PIECE THAT DOES NOT SEAL.
CONNECTING THE BATTERY PACK
1. Line up the key on battery cable
plug with the slot in female connec-
tor on battery pack.
2. Push the plug into female connector
and turn _ turn to secure.

card the respirator immediately if the
facepiece becomes discolored,
crazed, blistered or cracked, or if
other signs of deterioration of the
facepiece, motor-blower, filter or bat-
tery pack are observed.
You can breathe through the respi-
rator with the motor-blower off, but
breathing resistance may be
noticed, as with a negative-pressure
respirator.

Turn the motor-blower off before enter-
ing a decontamination shower. The
OptimAir MM 2K still provides respira-
tory protection with the motor-blower
off, because all air is still drawn through
the filter. However, breathing resistance
will be greater than when the motor-
blower is supplying air to the facepiece.
REMOVING THE RESPIRATOR
1. Return to fresh air and clean the
outer surfaces of the respirator
before removing the facepiece.
2. Turn the power switch off.
3. Place your fingertips behind the
headstraps. Place your thumbs on
the buckles.
4. Pull the top of the buckles away
from your head. Repeat as needed
to loosen the headstraps.
5. Grip the facepiece by the inhalation
housing.
6. Pull the facepiece
out, then up over
your head.
Do not pull the Ultravue facepiece by
the exhalation valve assembly. The
facepiece rubber or the valve assem-
bly can be damaged.
7. Remove the retaining clip from your
shirt or belt.
8. Remove the support belt. Be careful
that you do not drop the battery
pack.

MAINTAINING THE RESPIRATOR
MAINTAINING THE RESPIRATOR
A maintenance program must be estab-
lished. This program must include
cleaning and sanitizing, component
inspection and replacement of worn or
damaged parts. See the appropriate
parts lists for correct replacement part
numbers.
Only trained personnel are to main-
tain the respirator. Use only genuine
MSA parts. Do not make repairs or
design modifications other than as
recommended by MSA or NIOSH cer-
tification will be voided.
FILTER AND BATTERY PACK
Service Times
Filter and battery pack (P/N 10022696)
are designed to supply a minimum of
four cubic feet per minute (cfm) of res-
pirable air to the facepiece for a shift.
Actual service time may vary; however,
air flow must not drop below 4 cfm.
Factors which will affect how long the
filter can be used include the type and
concentration of the contaminant. If
breathing resistance is noticeable,
replace the filter.
1. Replacing the filter:
The filter is not designed to be
cleaned and reused. Do not try to
clean the filter. You may damage the
inside of the filter and eliminate res-
piratory protection, resulting in seri-
ous respiratory injury or death.
Do not remove the filter in a contami-
nated area. Return to a safe atmos-
phere and remove any contaminant
from the surface. Do not remove the
filter while the motor-blower is run-
ning.
With the filter removed, contamina-
tion from the surfaces of the respira-
tor can be drawn into the facepiece.
Failure to follow this warning can
result in serious respiratory injury or
death.
a. Turn the motor-blower off.
b. Clean the surface of the filter.
c. Turn the filter counter-clockwise
(left) and unthread it from the
motor-blower.
d. Ensure the gas-
ket located in
the air intake
hole on the side
of the motor-
blower is in
place.
Do not install the filter or use the res-
pirator if the gasket is missing or
appears damaged. Failure to follow
this warning can cause the contami-
nant to be drawn into the respirator
and can result in serious respiratory
injury or death.

MAINTAINING THE RESPIRATOR
e. Thread the new filter into the
motor-blower air intake and
hand-tighten against the gasket.
2. Replacing the battery pack:
a. Remove the pack from the sup-
port belt.
b. Loosen the ring and pull the two
connectors apart.
c. To re-install the battery pack, clip
the battery pack on the support
belt.
d. Line up the key on the battery
cable plug with the slot in the
female connector on the battery
pack.
e. Push the plug
into the female
connector and
turn the ring _
turn to secure it.
Inspect the respirator after it has
been cleaned and sanitized. Failure
to observe this warning can cause
you to be exposed to the contami-
nant, resulting in serious personal
injury or death.
CLEANING AND DISINFECTING
Confidence Plus™ Germicidal Cleaner
(P/N 10009971) from MSA is recom-
mended. Refer to the label for use
instructions. A solution as effective as
Confidence Plus Cleaning Solution and
compatible with MSA respirator compo-
nents may be substituted.
Be careful that you do not breathe or
touch the contaminant in handling
the respirator or its parts. Use equip-
ment designed to protect you from
the specific contaminant. Failure to
follow this warning can result in
serous personal injury or death.
1. Preparing the cleaner:
a. Follow the instructions with the
Confidence Plus Cleaning
Solution.
b. If the Confidence Plus Cleaning
Solution is not used, prepare in
accordance with the instructions
provided with cleaning products.
2. Remove excess contaminant from
the respirator. A vacuum cleaner
equipped with high-efficiency filters
to prevent recirculation of contami-
nant may be used.
3. Unthread the motor-blower thread-
ed insert from the facepiece inhala-
tion housing.
4. Clean and disinfect the facepiece:
a. Remove filters, cartridges, or
canisters from the facepiece.
b. Remove any protective cover
lens. This will prevent water from
becoming trapped between the
primary respirator lens and the
cover lens (the trapped water will
obscure vision).
c. Remove the nosecup (if used).
This will facilitate cleaning the
inside of the facepiece.
d. Remove the exhalation valve
cover. This will allow access to
the rubber exhalation valve.
e. Thoroughly wash the facepiece
and components in the cleaning
solution. A soft bristle (not wire)
