Principle of Operation / Battery Pack
EVA Series - Principle of Operation
The EVA Series Powered Air-Purifying Respirator (PAPR) System is configured
in six parts:
1. The blower and belt assembly:
EVA1 Blower Unit
EVABELT1 Comfort Belt
PA4AFI Air Flow Indicator
2. The battery pack (Part No. EVABAT2). One fully charged pack will power the
blower for approximately 4 to 10 hours depending upon factors such as
speed, cartridge selected and cartridge loading.
NOTE
The EVABAT2 is green and is not for use with Loose Fitting Hoods or Loose
Fitting Face Pieces.
3. The PA4BT Mask breathing tube assembly (standard length)
4. The High Efficiency Particulate Arrestance (HEPA or HE) filter (Part No.
PAPRFC3) or combination chemical cartridge OV/CD/CL/HC/HF/SD/HE
(Part No. PAPRCF4).
5. The Full Face Mask:
The following models may be used with the EVA Series blower unit:
PASPECML (Medium/Large)
PASPECS (Small)
6. The Battery Charger:
EVASMC Quick charger
EVAGC Gang charger
The blower unit draws in ambient air through the cartridge. The purified air
is blown into the wearer’s mask through the breathing tube. A flow indicator
is provided to check that there is an adequate volume of air available to the
wearer prior to use. The system is designed to operate at a minimum air flow
of approximately 4.5 cubic feet of air per minute (128 liters per minute) in the
mask under normal use on the standard speed setting, and 5 cubic feet of air
per minute (142 liters per minute) in the mask under normal use on the high
speed setting. A feedback loop from the Mass Flow Sensor to the impellor
continually monitors and adjusts the air flow to keep it constant at the design
set point.
The units are designed for use at temperatures from 23ºF to 129ºF
(-5ºC to 35ºC). A high temperature alarm will sound at 122ºF (50ºC)
The battery pack mounts in a compartment on the back of the blower. A fully
charged battery pack will power the blower for approximately 4 to 10 hours
depending upon factors such as speed selected, cartridge selected, and filter/
cartridge loading.
The EVA Series Blower is equipped with two alarms: A 77 db continuous
alarm will sound when the air flow reaches approximately 115 lpm and a
77db intermittent chirp alarm will activate to indicate that the battery has
approximately 15 minutes of remaining capacity.
Type C Airline Respirators
Spectrum Series Continuous Flow (TC-19C-0322),
Pressure Demand (TC-19C-0354), Combination Escape
SCBA & Type C Pressure Demand (TC-13F-0387,
TC-13F-0388)
The Spectrum Full Face Mask used with the EVA PAPR can also be configured
for use in Supplied Air Configurations. Refer to the corresponding Spectrum
Series Supplied Air Respirator User Instructions above for details.
Battery Pack
One fully charged battery pack will power the blower for approximately 4 to 10
hours depending upon factors such as speed selected, cartridge selected and
filter/cartridge loading.
NOTE
The battery has built-in short circuit protection. In the event of a short
circuit, an internal polyfuse will trip. The fuse will reset itself within 5-10
seconds allowing the battery to resume normal operation.
To charge the battery pack, do the following:
• Press the battery release on the pack to remove the battery from the back
of the blower. (See Figure 1.)
• Place battery upside down into the charging port of the battery charger.
(See Figure 2.)
• Connect the battery charger to a 110-volt AC electrical outlet.
• Charge the battery pack for approximately 4 hours.
While the battery is charging, the light on the charger will remain red. The
charger light will illuminate green when charging is complete.

Battery Pack / Pre-Operational Inspection
�WARNING
DO NOT charge batteries in hazardous areas.
Battery Storage
Storage of Li Polymer batteries is relatively easy. Unlike Nickel batteries, they
lose a very small amount of power (less than 0.5% per day) and therefore can
be charged and stored ready for use. If long-term storage is required, it is best
to store the battery in a cool place, not below -5ºC with at least 40% charge still
remaining.
NOTE
Discharging and re-charging the battery fully at least once every 3 months
is suggested to ensure the longest possible life of the battery. Do not
leave on the charger more than 30 consecutive days
To maximize battery life, these guidelines should
be followed:
• Remove the battery from the blower unit when not in use.
• Charge the battery before it is completely discharged. The low battery
alarm indicates that the battery needs to be charged. The battery is
designed with a circuit to protect the battery. It will not allow the battery
to be discharged below a safe voltage for the cells, regardless of airflow,
without the alarm sounding. When the battery reaches the voltage cutoff it
will automatically cease operation.
• Always charge the batteries at room temperature or cooler. At higher
temperatures, the battery pack may not accept a full charge. If the battery
pack feels hot, let it cool for 30 minutes before charging.
• Do not charge battery packs in an enclosed cabinet without ventilation.
Battery Fuel Gauge:
EVA Battery Packs are equipped with
an on-board fuel gauge to indicate the
amount of remaining capacity left in
the battery pack. To check the remain-
ing capacity, simply depress the button
labeled “Push” and LEDs will illuminate
indicating the level of battery capacity remaining. When fully charged all four
LEDs will illuminate green, and when 25% or less charge is available a single
LED will illuminate red.
Pre-Operational Inspection
Prior to each work shift, perform the following Pre-Operational Inspection to
ensure proper operation and to ensure that the unit is completely assembled.
1. Belt Mounted Blower Unit, Part No. EVA1
• Check that the unit is clean and undamaged.
• Inspect for deterioration, physical damage and improper assembly.
2. Filter/Cartridges
• Inspect the filter/cartridge for any physical damage
• Check the label to ensure the filter/cartridge has not exceeded its “use-by” date.
• Inspect the gasket on the filter for any physical damage.
NOTE
Each filter comes with a permanent gasket.
• Ensure that the correct filter/cartridge is appropriate for the contaminant.
• Consult the NIOSH approval label and your own in-plant safety professional if
you have any questions as to the suitability and efficiency of the
Air-Purifying Element.
• Screw the cartridge into the port until hand-
tight and the locking tab is secure. (Refer to
Mounting and Replacing Filters on Blower
Unit on page 4)
3. Battery Pack
NOTE
The EVABAT2 is green and is not for use
with Loose Fitting Hoods or Loose Fitting
Face Pieces.
• Check that the battery is not damaged.
• Check the Fuel Gauge to determine sufficient charge is available.
• Place the battery pack in the battery compartment on the blower.
• The battery tab should click when completely engaged. (See Figure 4)
4. Full Facepiece and Breathing Tube
• Inspect the full facepiece for any physical damage, such as torn head harness
straps, scratched or cracked visor and distortion of the rubber flange.
• Inspect the breathing tube for tears, cracks, holes or excessive wear that might
reduce the degree of protection originally provided.
• Ensure that the rubber seal is present in the mask inlet.
• Replace any damaged parts with the proper Bullard replacement part to
maintain the NIOSH approval.
Mounting the Breathing Tube on the Blower
• Ensure that a rubber gasket is in place in the breathing tube coupler on the
blower unit.
• Screw one end of the breathing tube into the blower unit. (Hand tight is
sufficient.) (See Figure 5).
• Ensure that neither the breathing tube nor
the filter is blocked.
• Ensure that the ON/OFF Switch is in the
OFF position.
• Switch on the blower by pressing the on/off
button for 1-2 seconds confirmed by a
short beep.
• If the Low Battery Alarm sounds at this
time, the battery needs to be recharged. See

Checking Airflow / Air-Purifying Elements
Checking Airflow with the Airflow Indicator
(PA4AFI - sold separately)
With the blower switched ON and the filters/
cartridges mounted, take the free end of the
breathing tube in one hand, hold it upright and
place the Airflow Indicator into the end of the
tube. (See Figure 6).
Apply a light downward pressure to the Airflow
Indicator to get a reasonable seal at the
breathing tube end. Ensure that the air outlet
holes in the Airflow Indicator tube are not
blocked. Two hands may be used if preferred,
one to hold the breathing tube and one to hold
the Airflow Indicator.
The position of the ball in the Airflow Indicator
should be observed. If any part of the ball is
below the PASS LINE on the Airflow Indicator, check for:
• Blower malfunction.
• Clogged or damaged Air-Purifying filter elements on the HE filter. See
“Mounting and Replacing Cartridges on the Blower Unit”.
• Low battery or battery malfunction.
If the ball is completely above the PASS LINE on the Airflow Indicator, then the
system is ready for use.
�WARNING
If the blower malfunctions during use in a hazardous area:
Remain calm and LEAVE the hazardous area immediately.
DO NOT use a blower that fails the flow test (air flow indicator sold separately).
Use ONLY Bullard filter/cartridges which comply with and have the NIOSH
approval label and which are appropriate for the contaminant.
Failure to observe these warnings could result in death or serious injury.

Donning the Blower and Respirator
Initial Donning
Prepare to don the blower, battery and facepiece in a safe, hazard-free area
and do the following:
• Ensure that the cartridge used is suitable for the contaminant in question
and is compatible with the EVA Blower Unit.
�WARNING
The use of any filter/cartridge not approved with the EVA blower units
may put the user at risk and could result in death or serious injury.
• Check that the filter/cartridge is properly mounted on the blower unit.
• Place the battery in the battery compartment on the back of the blower.
• Fit the blower and belt around the user’s waist and adjust the belt for a
comfortable fit.
• Remove the belt and blower.
• Ensure that the rubber seal is present in the mask inlet. Screw the
breathing tube elbow into the mask inlet until tight. (See Figure 16)
Donning the Spectrum Full
Facepiece
Release the headstraps to the full outward
position by pulling the headstrap quick
release tabs forward. When fully
extended, tabs should be located at the
headstrap latches.
Grasp the headstrap harness with thumbs
through the straps.
Spread outward.
Push the top of the facepiece
flange up the forehead, brushing
hair upward from the face seal area
(see Figure 17). Continue up and
over the head until the harness is
centered at the rear of the head,
and the chin rests in the chin cup.
Pull both lower straps at the same
time towards the rear (see Figure 18). Tighten
the two temple straps. Tighten the top head
strap if necessary.
Adjust headstraps until the facepiece fits
securely and evenly.
Perform a negative pressure fit check:
A. With facepiece on and secured, place your
hand over the end of the breathing tube
(see Figure 19).
B. Inhale until the mask collapses inward
lightly (indicating there is negative pressure).
Hold your breath for five seconds.
C. The mask is deemed to be in proper position if it remained collapsed while
the breath was held, and no inward leakage of outside air
was detected.
D. If the mask doesn’t collapse or if an inward leak is detected, re-adjust
mask on face and repeat above steps until the test is passed.
�WARNING
Persons wearing tight fitting masks, such as the Spectrum Series, are
required by OSHA to be fit tested before initial use and at least annually
thereafter. Seal checks are to be performed before each use. If you
cannot attain a proper fit test and seal, try another mask size and repeat
the steps outline previously. If a proper fit and seal is still not achieved
do not use the respirator.
Turn on the blower, and attach the breathing tube to the blower. With the air
flowing into your respirator, you are now ready to enter the work area.
�WARNING
The mask exhalation valve cover must be used when operating this
respirator. This part protects the exhalation valve from outside
interference. Failure to follow these instructions could result in death
or serious injury.

• Remove any protective film covering the lens of the mask.
• Put on the belt and blower assembly and make any final adjustments to
the belt as necessary.
• Turn the blower on by depressing and
holding the on/off switch (Figure 20) for
approximately 1 second indicated by a
short beep.
• Buckle the belt onto the waist (blower
unit should be in the lower back of
the wearer).
• Choose speed setting (see below).
�WARNING
Do not enter a hazardous area until you are sure that the blower and mask are
fully operational and the blower is running. The user should periodically leave the
hazardous area to check the airflow through the system. If the low battery or low
flow alarm should sound, or if the user experiences any difficulty in breathing, or
senses any taste or any odors from the hazard, the user should leave the hazardous
area immediately. Failure to observe these warnings could result in death or
serious injury.
Speed Selection
The EVA1 Blower is equipped with the ability for the user to select one of two
speeds for operation.
When the unit is initially turned on and green EVABAT2 is installed, the blower
will operate at approximately 5.0 cfm=142 lpm.
NOTE
The battery life is reduced at the higher speed.
Pressing the on/off switch will change the speed to approximately
4.5 cfm = 128 lpm (low speed).
Pressing the on/off switch additional times will toggle the unit between the
two speeds.
NOTE
Speed change is confirmed by a short beep.
Low Battery Alarm and Low Flow Alarm
The EVA1 Blower unit is equipped with a Low Battery Alarm and a
Low Flow Alarm.
The Low Battery Alarm will sound an intermittent 77 dba electronic beep
indicating that there are approximately 15 minutes of remaining battery
capacity. The delays between beeps will get shorter and shorter as time
runs out.
The Low Flow Alarm will sound a continuous 77 dba electronic beep indicating that
the flow to the mask has dropped below the design specification of
115 lpm = 4.0 CFM (Note: The NIOSH minimum required flow is 115 lpm=4 CFM).
Low Battery Alarm and Low Flow Alarm
(continued)
When either of these alarms sounds, the user should immediately do
the following:
Leave the hazard area
Remove the headpiece
Disconnect the breathing tube from the mask
Check the airflow with the airflow indicator (see page 4).
If the airflow indicator indicates insufficient airflow, the battery should be
fully charged (see “Battery Pack” on page 2), and/or the filter/cartridge
should be replaced.
NOTE
The EVA1 blower is provided with a circuit to protect the battery. It will
not allow the battery to be discharged below a safe voltage for the cells,
regardless of airflow, without the Alarm sounding. When the battery
reaches the voltage cutoff it will automatically cease operation. When
the Low Battery Alarm sounds and the filter cartridge is not clogged, the
battery should be recharged to protect the battery and thereby prolong
the working life of the unit. If the ball in the Airflow Indicator is BELOW
or PARTLY BELOW the PASS LINE with a fully charged battery, the filter
cartridge may need to be changed.
Doffing the Respirator
Prepare to doff the blower, battery and mask in a safe, hazard-free area
and do the following (in conjunction with your employer’s standard
operating procedures):
• Remove the mask by lifting the tabs on the latches.
• Turn the blower off by holding down the on/off switch for 5 seconds. This is
confirmed by a long beep and a shut down of the motor.
• Remove the waist belt.
• Disconnect the mask from the breathing tube.
• Disconnect the breathing tube from the blower.
• Clean and inspect components as necessary.
• Place battery on charger (as desired).
• Place components in storage.
�WARNING
The use of any filter/cartridge not approved with the EVA1 blower unit
may put the user at risk and could result in death or serious injury.

Respirator and Spectrum Full Face Mask will be free of defects in material and
workmanship under normal use and service for a period of one (1) year from the
date of purchase. Bullard’s obligation under this warranty is limited to repairing
or replacing, at its option, articles that are returned within the warranty period
and that are, after examination, shown to Bullard’s satisfaction to be defective,
subject to the following limitations;
a) EVA Powered Air-Purifying Respirator and Spectrum Full Face Mask must be
returned to the Bullard factory with shipping charges prepaid.
b) EVA Powered Air-Purifying Respirator and Spectrum Full Face Mask must not
be altered from its original factory configuration.
c) EVA Powered Air-Purifying Respirator and Spectrum Full Face Mask must not
have been misused, subjected to negligent use, or damaged in transport.
d) The date of purchase is within the one year warranty period. (A copy of the
purchaser’s original invoice showing the date of purchase is required to
validate warranty coverage.)
In no event shall Bullard be responsible for damages for loss of use or other
indirect, incidental, consequential or special costs, expenses or damages
incurred by the purchaser, notwithstanding that Bullard has been advised of the
possibility of such damages.
ANY IMPLIED WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY
AND FITNESS FOR A PARTICULAR PURPOSE, ARE LIMITED IN DURATION TO
ONE (1) YEAR FROM THE DATE OF PURCHASE OF THIS PRODUCT.
Some states do not allow the exclusion or limitation of incidental or
consequential damages, or allow limitations on how long an implied warranty
lasts, so the above limitations or exclusion may not apply to you. This warranty
gives you specific legal rights, and you may have other rights which vary from
state to state.

authorization number as well as the labels you will need to return the product.
3. Before returning the product, decontaminate and clean it to remove any
hazardous materials which may have settled on the product during use.
Laws and/or regulations prohibit the shipment of hazardous or contaminated
materials. Products suspected to be contaminated will be professionally
discarded at the customer’s expense.
4. Ship products to be returned, including those under warranty, with all

returned to you, Bullard will invoice you for actual work performed.
Respirator Fit Testing
According to OSHA’s revised Respiratory Standard, 29 CFR 1910.134, all tight-fitting facepieces must be fit tested, regardless of the mode of operation. This includes
all respirator models in the EVA Series when used with the Spectrum Series Full Facepiece. Users must pass either a qualitative or quantitative fit test, and fit testing
must be performed in the negative pressure mode. Bullard’s QNFT45 fit test kit converts the Spectrum facepiece to the negative pressure mode, and can be used for
quantitative fit testing. The instruction sheet that accompanies the kit provides guidance on its proper use.
Use the Bullard HFC45 HEPA filter cartridges for qualitative fit testing with irritant smoke, Saccharin or Bitrex (denatonium benzoate). Quantitative options include
generated aerosol, ambient aerosol CNC, (TSI Portacount method), or controlled negative pressure (OHD Fit Tester 3000 method).
Fit testing shall be performed prior to initial use, whenever a different respirator is used, and at least annually thereafter. An additional fit test must also be performed
whenever there are changes in the employee’s physical condition that could affect respirator fit, such as dental changes or an obvious change in body weight.
