1.The blower assembly (Part No. PA3) which includes:
PA3BU Blower Unit
PA1SB Belt or PA1DB Decon Belt
PA1AFI Air Flow Indicator
The blower unit draws in ambient air through the filters/cartridges. The purified air is
blown into the wearer’s hood 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 units are designed for use at temperatures from 10ºF to 120ºF (-12ºC to 49ºC).
The system is designed to operate at a minimum air flow of approximately seven cubic
feet of air per minute (210 liters per minute) in the hood under normal use.
2.The battery pack (Part No. PA3BP). One or two packs can be used. One fully
charged pack will power the blower for approximately four to five hours.
The battery pack(s) mount in compartment(s) on the back of the blower. One fully
charged battery pack will power the blower for approximately four to five hours
(PA3BU). Two fully charged packs (PA3BU) will run for approximately eight to ten hours.

PA3 Blower Assembly User Manual
Battery Pack
Initial Charging Procedure with Quick Charger
A fully charged battery pack will power a blower unit to provide adequate air volume for
the respirator for approximately four to eight hours for the PA3BU under normal working
conditions, depending on whether one or two battery packs are used.
To ensure a full charge on a new battery pack, follow these important guidelines. These
guidelines also apply to battery packs that have been in storage for extended periods of
time.
To charge the battery pack, do the following:
For new battery packs or packs that have been in storage for extended periods of time,
follow the directions above under “Battery Pack”, and when the light begins to flash on
the charger, do the following:
• Open the battery latch and remove the battery from the back of the blower.
• Remove the battery pack. Wait 15 seconds. Replace the battery pack in the nest. The
charger light will now remain on.
• When the light begins flashing again, remove the battery pack. Wait 15 seconds.
Replace the battery pack in the nest again. The charger light will now remain on.
The charger light will flash a third time, indicating that the battery is fully charged.
This procedure should also be followed after periods of prolonged storage. Without
periodic charging, the nickel metal hydride batteries will lose up to 1%–2% of their charge
per day. Allowing a battery to self-discharge during periods of prolonged storage will not
damage the battery.
Warning
DO NOT charge batteries in hazardous areas.
Pre-Operational Inspection
Figure 1
• Place each battery in the charging ports of the battery charger. Ensure that the battery
contacts line up with the contacts in the charger port (see Figure 1).
• Connect the battery charger to a 115-volt AC electrical outlet.
Prior to each work shift, perform the following Pre-Operational Inspection to ensure
proper operation and to insure that the unit is complete.
Charge the battery pack for approximately eight hours.
• Check that the unit is clean and undamaged.
• Inspect for deterioration, physical damage, and improper assembly.
• Ensure that the correct filters/cartridges for the appropriate contaminant are
properly mounted on the blower unit. Screw the cartridges into the ports until handtight.
While the PA3BP battery is charging, the light on the charger will remain on. The charger
light will flash when charging is complete.
Table-top gang chargers (Part No. PA3GC, with 5 ports) are also available.
1.Belt Mounted Blower Unit, Part No. PA3BU
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.
Warning
PA3BP battery packs MUST be used with PA3 blower units. Interchanging these
batteries with other blowers may cause damage to the blower and battery AND the
blowers will not operate as intended and may put the wearer at risk. Failure to follow
these instructions may result in death or serious injury.
• Check that the battery is not damaged.
• Place the battery pack in the battery compartment on the blower by first engaging
the tab on the pack under the lip on the edge of the compartment. Then close the
latch. Place a second battery pack in the other compartment, if desired (PA3BU only).
If only one battery is used, install the PA3BPC battery port cover over the unused
port (for PA3BU).
3. Hood with Suspension or Hard Hat, or Loose Fitting Facepiece
• CC20 Series and RT Series hoods are constructed of either Tychem QC or Tychem SL.
Depending on the model selected, it may be used with either a headband suspension
or a hard hat. The loose fitting facepiece is constructed of Tychem QC and features
an internal suspension.
• All CC20 Series and RT Series hoods and loose fitting facepieces are approved for
use with the PA3BU Blower Unit.
• Inspect the hood or loose fitting facepiece for any physical damage.
www.bullard.com
Battery Pack/Pre-Operational Inspection
To maximize battery life, these guidelines should be followed:
• Charge the battery pack before it is completely discharged. The low voltage alarm
indicates that the battery needs to be charged; operating the PAPR for more than 20
minutes after the alarm has been activated may damage the battery. Deeply discharged
batteries may cause the charger to falsely indicate a complete charge.
• Always charge the batteries at room temperature or less. 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 capacity may be checked with the battery analyzer/conditioner.

Mounting the Breathing Tube on the
PA3BU Blower
Ensure that a rubber gasket is in place in the breathing tube coupler on the blower unit.
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.
Screw one end of the breathing tube into the blower unit (hand tight is sufficient) (see
Figure 2).
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:
Ensure that neither the breathing tube nor the filter is blocked.
• Blower malfunction.
• Clogged or damaged Air-Purifying filter elements on the HE filters or the
combination cartridges with HE filters. See “Mounting and Replacing Cartridges
on the Blower Unit” on page 7.
• Low voltage or battery malfunction.
If the ball is completely above the PASS LINE on the Airflow Indicator, then the system
is ready for use.
NOTE
n the PA3BU unit, due to the back-pressure of the ball, the Low Voltage Alarm
O
may sound when a reading is being taken. If the ball bounces, let it stabilize, and
then read the lowest point.
When the blower passes the flow test, it is ready to use.

Ensure that the ON/OFF Switch is in the OFF position.
Switch on the blower. If the Low Voltage Alarm sounds at this time, the battery needs
to be recharged. See instructions on page 4 regarding properly charging the battery.
NOTE
On the PA3BU unit, the low voltage alarm will sound a short beep as the power
switch is cycled on and off, indicating that the alarm is functioning properly. The
alarm will sound continuously to indicate low voltage.
If the blower malfunctions during use in a hazardous area:
DO NOT remove the respirator hood, blower or waist-belt while in the hazardous
area.
DO remain calm and LEAVE the hazardous area immediately.
After reaching a hazard-free area, immediately remove the respirator.
DO NOT use a blower that fails the flow test.
Use only Bullard 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.

*These tests are part of the performance specifications for the C2A1 military canister. The PA3NBC Cartridge meets or exceeds the performance requirements of the C2A1
canister for these gases.
HE particulate filters are 99.97% effective against all particulate aerosols.
Filters and cartridges are supplied in quantities of six per box.
The following abbreviations are approved by NIOSH to indicate the particulates, gases
or vapors which are removed by the gas/vapor cartridges:
Use only the filter/cartridge described in the above table. Used/particulate-laden cartridges
must be changed as a set and not individually. All cartridges must be of the same type. Do not
change cartridges while in a hazardous atmosphere. Incorrect cartridge selection will invalidate
all performance statements and approvals for this equipment.
Three (3) of the same type of filter/cartridge must be used on the PA3BU blower unit, with the
exception of the PAPRFC1 filters which are used two (2) at a time, in conjunction with the PA3PG
plug. DO NOT use the PA3PG plug to close off a port with any other cartridge type.
These respirators are not NIOSH-approved for use against chemical warfare agents.
The respirator and cartridges should not be used beyond eight (8) hours after initial exposure
to chemical warfare agents to avoid possibility of agent permeation. If liquid exposure is
encountered, the respirator should not be used for more than two (2) hours.
Follow established cartridge change schedules to ensure that cartridges are replaced before
breakthrough occurs. Failure to follow these warnings could result in death or serious injury.

Mounting and Replacing Filters/Cartridges on the Blower
Unit
Screw the air-purifying elements into the receptacles (see Figure 5) until the filter/
cartridge is hand tight. DO NOT OVER-TIGHTEN.
The useful life of a chemical cartridge for vapors and gases will vary with the
concentration and nature of the contaminant, the breathing rate of the respirator
wearer, and ambient temperature and humidity.
The Occupational Safety and Health Administration (OSHA) regulations 29 CFR 1910.134
require that the employer must implement a change schedule when using Air-Purifying
respirators for protection against gases and vapors, if there is no end-of-service-life
indicator on the cartridges. The change schedule must be based on objective data that
will ensure that the cartridges are replaced before the end of their service life. Factors
to consider include workplace conditions such as contaminant concentration, relative
humidity, temperature, work activities, respirator use pattern (e.g., continuous or
intermittent use), presence of other contaminants, potential for contaminant migration/
desorption, health effects of the gas or vapor, and the presence of any warning
properties. Contact Bullard for further information on change-out schedules.
High efficiency particulate filters must be replaced when retained particles clog the
filters and reduce air flow below acceptable levels, as indicated by testing with the Air
Flow Indicator. See page 5.
To Replace Filters/Cartridges
Remove the air-purifying element from its packaging, and inspect for damage. If in
doubt do not use.
Figure 5
When using the two PAPRFC1 filter cartridges, install the filter plug into
one of the ports. DO NOT OVER-TIGHTEN (Figure 6).
Check that the air-purifying element has not exceeded its “use-by” date and that the
connecting thread is in good condition.
Check that the air-purifying element is appropriate to the hazard. If in doubt consult your
respirator program administrator or supervisor.
Check that the threads in the blower unit port are in good condition and clear of
contaminant.
Check that the PA3BU blower ports have the rubber gasket seals present.
Remove the air-purifying element seals (see Figure 4).

Final Donning:
NOTE
For additional information on hood donning, doffing, usage and care consult the
CC20 Series or RT Series user manuals available at www.bullard.com.
Warning
Do not enter a hazardous area until you are sure that the blower and hood 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 PA3BU voltage
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.
PA3BU Low Voltage Alarm
20LFL
20LF2L
If the airflow indicator indicates insufficient airflow, the battery should be fully charged
(see “Battery Pack” on page 3), and/or the filter/cartridge should be replaced.
The PA3BU Low Voltage Alarm must not be solely relied upon as an indication of a low air
flow condition. Only the Air Flow Indicator should be utilized for checking for adequate
air flow, as required by NIOSH.
NOTE
T he PA3BU 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 Low Voltage Alarm sounds and the
filter cartridges are 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 cartridges may need to be changed.
The PA3BU Blower unit is equipped with a Low Voltage Alarm. This device will activate
if the battery voltage is below acceptable levels. The PA3BU Low Voltage Alarm is an
electronic 77 dba beep. The alarm is internal to the blower and the sound will be carried
up the breathing tube into the hood. Sounding of the alarm indicates that insufficient
airflow may be imminent. The user should immediately do the following:
Leave the hazard area, remove the headpiece, disconnect the breathing tube from the
hood and check the airflow with the airflow indicator (see page 4).

Loose-Fitting Facepiece Use/Final Donning/Low Voltage Alarm
• Attach the other end of breathing tube to blower unit (if not already attached) by
screwing adapters together.
• Remove any protective film covering the lens of the headpiece.
• Put on the belt and blower assembly and make any final adjustments to the belt as
necessary, keeping the breathing tube and hood behind the head.
• Turn the blower on by depressing and holding the on/off switch.
• Buckle the belt onto the waist (blower unit should be in the lower back of the
wearer).
• Don the headpiece.
• Place the hood on the head making any final adjustments to the fit as required at
this time to ensure a comfortable and stable fit.
•Tuck inner bib into coveralls or shirt if using a hood with inner bib.

Warning
Troubleshooting/Cleaning and Storage
Avoid contaminant entry into the breathing tube, as this will compromise respiratory
protection and could result in death or serious injury. Consult your local safety
professional if you suspect that contaminant has entered the breathing tube. When
cleaning the equipment, do the following:
10
Ensure water does not enter cartridges. Replace wet cartridges.
DO NOT use gasoline, organic-based solvents, or chlorinated degreasing fluids (such
as trichloroethylene) as they will cause damage.
DO NOT immerse the equipment in water or other cleaning fluid as this may cause
contamination in the breathing tube and blower interior that will be difficult to remove.
Failure to observe the instructions and warnings in this manual invalidates all
performance statements and approvals for this equipment and could result in death
or serious injury.
Once cartridges have reached the end of their useful life, discard in accordance with
federal, state, and local guidelines, and in conformance with plant safety regulations.
Use a lint-free cloth moistened in a mild solution of soap and warm water to clean the
outer surface of the equipment.
Consult the CC20/RT Series Tychem Hood User Manual available at www.bullard.com
for cleaning instructions for the hood components.
When the apparatus is completely dry, store in a clean, dry area, away from direct
sunlight and sources of direct heat.
The storage temperature should be between 32º F to 125º F (0º C to 51º C) with humidity
less than 90% RH.
