GENERAL INFORMATION
Bullard Free-Air Pumps transfer ambient air from a clean air location, where breath-
able air can be assured at all times, to workers wearing Type C or CE continuous
flow supplied-air respirator hoods or tight fitting half or full face masks.
The ambient air is filtered through a medium efficiency Inlet Air Filter and a Carbofine
Outlet Filter before entering the respirator’s air supply hose.
Bullard Free-Air Pumps are oil-less and have rotary carbon vanes. They produce no
carbon monoxide, oil vapors, oil mist or moisture. They do not require expensive
carbon monoxide monitors, high temperature alarms or airline filters. No calibration is
required.
NOTE: Drive-Air pressure (psig) determines horsepower of air motor which directly
affects output air pressure and output air volume. When operating a hood-style respi-
rator with a Frigitron 2000 Series air conditioner incoming drive air pressure must be
set at 95 psig for optimum pump performance. Attempting to operate a hood-style
respirator with a Frigitron air conditioner with the incoming drive air at less than 95
psig may result in an inadequate supply of air to the worker. See below for pump
performance.
On the charts below, find the relevant Output Air Pressure (psig) corresponding to the
respirator’s approved pressure range to determine the pump’s total air volume (cfm)
and a maximum number of respirators that can be used at that air volume.

tor is four (4) cfm and for each hood style respirator is six (6) cfm.
The ratings which appear here, therefore, are conservative, but reflect Bullard’s posi-
tion that worker respiratory protection is enhanced when air flow available to the res-
pirator wearer is above the NIOSH required minimums.

WARNINGS
READ ALL INSTRUCTIONS IN THIS MANUAL BEFORE USING FREE-
AIR PUMP MODEL ADP20.
FAILURE TO OPERATE THIS PUMP IN ACCORDANCE WITH THE
INSTRUCTIONS CONTAINED IN THIS MANUAL MAY RESULT IN DEATH
OR SERIOUS INJURY TO THE RESPIRATOR WEARER.
1. Locate the pump’s Inlet Air Filter in a place where there is clean,
breathable air at all times. The pump WILL NOT remove toxic gases
or other contaminants from the incoming air it transfers to the respi-
rator wearer.
See the BREATHING AIR REQUIREMENTS section on page 5 for spe-
cific details on breathing air quality.
2. This pump will supply at least the required minimum volume of air (6
cfm for hoods or 4 cfm for tight fitting masks) to low pressure, sup-
plied-air respirators. The respirators must be approved by
MSHA/NIOSH to operate at less than 25 psig.
Be sure that the pump’s outlet pressure, measured by the pressure
gauge on the pump, is maintained above the minimum pressure set-
ting required by the respirator manufacturer.
To be assured your respirator can be used with this pump refer to
the section in the respirator’s Instruction Manual for the respirator’s
approved pressure range and permissible air supply hose length.
If you have any questions about whether or not your respirator is
compatible with this pump, contact Bullard’s Inside Sales
Department at 800-827-0423 or 606-234-6611.
3. Supplied-air respirators used with this pump must not be worn in
any atmosphere immediately dangerous to life or health or from
which the wearer cannot escape without the use of the respirator.
4. When connecting your respirator to the Free-Air Pump use only the
air supply hose and couplings required by the respirator manufacturer
and approved by MSHA/NIOSH.
Use of non-approved hose or couplings will void the respirator’s
MSHA/NIOSH Approval and could reduce the air flow to the respirator,
resulting in possible death or serious injury to the respirator wearer.

ASSEMBLY AND INSTALLATION
FOR THE SPECIFIC LOCATION OF THE
PUMP COMPONENTS REFERRED TO
BELOW, SEE THE LIST OF PUMP COMPO-
NENTS ON PAGE 4.
Assembling the Free-Air Pump
1. Remove assembly from plywood shipping
board and attach four rubber feet through
four holes in skid.
2. Install stand pipe (2), and INLET AIR FILTER
(1) into threaded AIR INLET PORT (3).
3. Make sure the pump’s inlet air filter is locat-
ed in a clean, uncontaminated location
where breathable air is assured at all
times.
If the inlet air filter cannot be placed at a
source of clean, breathable air, install
Bullard’s 50 foot Inlet Extension Hose Kit
(Cat. No. V50IN) to the pump’s inlet port.
See the directions shipped with the
Extension Hose Kit for assembly instruc-
tions.
If clean breathable air cannot be guaran-
teed at all times within this 50 foot reach,
you may add up to five additional lengths of
50 foot Extension Hose (Cat. No. V50EX).
Therefore, you may place your Inlet Filter
up to 300 feet (6 x 50) away from the pump.
Do not add more than 300 feet of inlet
extension hose to the pump.
How Air Motor Works
1. Compressed air enters through drive Air
Inlet (16), passes through pressure regula-
tor/filter (15); where pressure is controlled
and excess oil and water are removed.
Air pressure is adjusted with REGULATOR
KNOB (17) and is read on GAUGE (4).
(NOTE: 80 psig or higher during operation
is normal for this motor).
2. Air passes through LUBRICATOR (12)
where oil is added and metered.
3. Lubricated air passes through THROTTLE
VALVE (10) and drives AIR MOTOR (9).
4. Air is exhausted through motor exhaust
muffler (18) to atmosphere.
How Motor Drives Pump
MOTOR drives pump through a flexible coupler.
There are no belts to maintain or tighten.
How Pump Supplies Air
Clean breathable air must be supplied to
PUMP INLET AIR FILTER (1) at all times
(See Breathing Air Requirements on page 5).
The pump draws in air using four sliding car-
bon vanes set in a rotor, and discharges it
under low pressure out of discharge port.
Air passes through Bullard’s CARBOFINE
OUTLET FILTER CARTRIDGE (6) located
inside OUTLET FILTER HOUSING.
Bullard’s CARBOFINE filter cartridge is multi-
layered with 40 micron size particles of acti-
vated carbon, a sorbent bed with an exposed
carbon surface of more than 15,000 square
feet.
NOTE: Change this outlet filter cartridge at
least every 200 running hours.
Filtered breathing air passes out through one,
two, or three couplers (8) to one, two, or three
supplied-air respirators depending on the
style of respirator(s) being used (See table,
page 1).
Note that two, 1/2" Industrial Interchange
quick-disconnect couplers are supplied with
the factory packed unit. You may replace
these couplers to conform with the hose and
respirator you are using.
Installation
NOTE: Use ample size hose from compressor
to pump; 1" or 3/4" internal diameter is best.
A larger diameter compressor air hose may
be required depending on operating condi-
tions and length of compressed air line.
The compressor must have capacity to contin-
uously supply at least 85 cfm of air at 95 psig
to drive the pump at its rated capacity.
7

Installation Continued
1. With the pump shut off, fill LUBRICATOR
(12) through fill cap with SAE 10 Automotive
Engine Oil to fill line on bowl. Do not use a
heavier grade oil than SAE 10. Be sure
drain valve at bottom of regulator is closed
2. Close THROTTLE VALVE (10).
3. ATTACH HOSE WITH RESPIRATORS
CONNECTED TO AIR OUTLETS (8) ON
PUMP.
4. Connect air supply to pump.
5. Adjust AIR REGULATOR so COMPRESSED
AIR GAUGE (4) reads 95 psig.
6. Pump is ready to run. Open THROTTLE
VALVE (10) build up speed and idle for a
few minutes.
7. Adjust THROTTLE VALVE (10) to run pump
at desired psig on OUTLET AIR PRES-
SURE GAUGE (5) and adjust OIL METER-
ING SCREW (13) until lubricator is produc-
ing approximately 1 DRIP PER MINUTE in
the SIGHT DOME (14). NOTE: This drip
rate should be monitored occasionally
during operation.
8. Adjust RELIEF-VALVE as follows: (NOTE:
The relief valve is preset at the factory to
“bleed off” at 25 psig.)
a. Loosen lock nut.
b. Pinch off respirator air supply hose to
create back pressure.
c. Speed up motor by opening throttle
valve.
d. Adjust relief-valve to “bleed off” at a
pressure 1 or 2 psig above that required
by respirator.
e. Slow down motor and check that no air
“bleeds” below required pressure.
f. Maximum output operating pressure is
25 psig.
NOTE: Pump will reach 150° - 200° F
during normal running conditions.

OPERATING THE FREE-AIR PUMP
WARNING : THE RESPIRATOR USER MUST NOT ENTER THE
CONTAMINATED WORK AREA UNTIL ALL OF THE FOLLOWING STEPS
HAVE BEEN COMPLETED
1. Analyze the atmosphere at the location of
the pump’s air inlet filter is located in a
clean, uncontaminated location where
breathable air is assured at all times. The
pump is equipped with a 2 ft. stand pipe to
keep the intake away from the air motor
exhaust port.
If the Inlet Filter cannot be placed at a
source of clean, breathable air, install
Bullard’s 50 foot Inlet Extension Hose Kit
(Cat. No. V50IN) to the pump’s inlet port.
See the directions shipped with the
Extension Hose Kit for assembly instruc-
tions.
If clean breathable air cannot be guaran-
teed at all times within this 50 foot reach,
up to five (5) additional lengths of 50 foot
Extension Hose (Cat. No. V50EX) may be
added.
Therefore, the inlet filter may be placed up
to 300 feet (6 x 50) away from the pump.
Do not add more than 300 feet of inlet
extension hose to the pump.
2. Be sure you have read and followed all
instructions for assembly and installation of
the ADP20 pump on pages 6 and 7.
3. Pump Model ADP20 will operate sitting on
its four rubber mounts. It does not need to
be bolted down.
4. Assemble your respirator by following the
manufacturer’s directions as described in
the respirator’s Instruction Manual. Be sure
the pump’s outlet pressure, measured by
the pressure gauge on the pump, is greater
than the minimum MSHA/NIOSH approved
pressure required to operate the respirator.
The respirator’s minimum approved pres-
sure will be found in the respirator’s
Instruction Manual and/or on labels
attached to the respirator.
If you have any questions as to whether or
not your respirator is compatible with this
pump, call Bullard’s Customer Service
Department at 800-827-0423 or
606-234-6611.
5. Connect the respirator’s MSHA/NIOSH
approved air supply hose(s) to the quick-
disconnect Outlet Coupling(s) on the pump.
A. OUTLET COUPLING
If your respirator’s air supply hose(s) have
1/2" Industrial Interchange quick-discon-
nect fittings and you want to supply air to
one or two hood, full face or half mask
respirators you may connect them directly
to the two female 1/2" quick-disconnect
couplers on the pump.
If you want to supply air to three full or half
mask respirators (the pump does not pro-
vide sufficient air volume for three hood
style respirators), you may purchase and
install an additional female quick-discon-
nect coupling (Cat. No. S16191).
B. CONNECTING AIR SUPPLY HOSE(S)
WITHOUT 1/2" QUICK-DISCONNECT
FITTINGS
If your respirator’s MSHA/NIOSH approved
air supply hose will not attach to the pump’s
standard 1/2" Industrial Interchange Outlet
Couplings, (see above) the hose fitting can
be adaptedto the pump by converting the
pump’s quick-disconnect outlet to 3/8"
female NPT with the installation of one or
more of the following adaptors.
Cat. No. V23 - Converts SINGLE outlet to
SINGLE 3/8" female NPT pipe thread.
Use Teflon tape or pipe thread sealer to
ensure an air tight seal.
A variety of quick-disconnect fittings may
then be used to connect the air supply
hose to the 3/8" outlet adaptor. Contact
your respirator’s manufacturer for the
proper fitting (Hansen, Parker, Snap-Tite,
Schrader, etc.)
9

6. Before connecting your respirator to the air
supply hose, turn the pump on. Allow the
air to flow through the pump and hose for a
few minutes to purge or expel any hose
odors or moisture that may have accumu-
lated inside the hose.
7. Connect the respirator to the air supply
hose using the quick-disconnect fittings.
8. Set the pump’s outlet pressure to within the
respirator’s approved pressure range by
adjusting the Throttle Valve (10).
9. With the air flowing, put on the respirator
by following the directions in the respirator
manufacturer’s Instruction Manual.
YOU ARE NOW READY TO ENTER THE
WORK AREA.
10. When finished working, leave the work
area wearing the respirator with the air
still flowing. Once outside the contaminat-
ed area, remove the respirator, turn the
pump off, then disconnect the air supply
hose using the quick-disconnect couplings.
See the respirator’s Instruction Manual for
proper inspection, maintenance and stor-
age procedures for the respirator you are
using.
10

MAINTAINING THE FREE-AIR PUMP
FOR THE PUMP TO OPERATE AT ITS OPTIMUM PERFORMANCE
LEVEL, THE FOLLOWING ROUTINE MAINTENANCE PROCEDURES
MUST BE PERFORMED.
FOR THE SPECIFIC LOCATION OF THE
PUMP COMPONENTS REFERRED TO
BELOW, SEE THE LIST OF PUMP COMPO-
NENTS ON PAGE 4.
Maintaining The Air Motor
The air motor is a rotary 4-vane type. The
vanes require no adjustment and will last
5,000-15,000 hours if properly maintained.
1. Maintain INLET AIR PRESSURE
REGULATOR FILTER (15):
- It is equipped with a 40-micron filter ele-
ment that can plug up if air supply is not
prefiltered at the compressor.
- Remove and clean filter periodically to
prevent clogging.
2. Maintain LUBRICATOR (12):
- Keep filled with SAE 10 Automotive oil.
(Do not use a heavier grade)
- Maintain drip rate at approximately 1 per
minute.
- DO NOT fill while running or while under
pressure.
3. Flush MOTOR (9):
If motor is sluggish or inefficient, flush with
LOCTITE Safety Solvent, or any non-toxic,
nonflammable industrial cleaning solvent).
Use the following directions to flush the
motor:
a. Shut-off the pressure into the air motor
and disconnect the airline from the Drive
Air Inlet (16).
b. Locate the pump in a safe area. Solvent
will spray from the exhaust port during
flushing. Protect your face and eyes
from the spray.
c. Remove the Plug (11) and pour several
teaspoons of solvent into the opening.
d. Replace the Plug, reconnect the airline
back to the Drive Air Inlet. Turn the pres-
sure back on.
e. Run the pump at a very low speed (10-
20 RPM) for approximately 1 minute or
until all the solvent is flushed.
NOTE: Motor bearings are grease
packed and sealed. They require no
maintenance.
Maintaining The Pump
Pump is rotary 4 vane type. The vanes take
require no adjustment and will last 5,000 to
10,000 hours if properly maintained.
1. Maintain FILTERS
- Dirty filters restrict outlet air flow and can
cause the motor to overload or cause
premature pump failure.
- Replace CARBOFINE OUTLET FILTER
CARTRIDGE (6) at least once every 200
running hours (Catalog No. S17101).
- Replace INLET FILTER (1) at least once
every 500 running hours to maintain
proper pressure and full air flow. To
check the filter - while running the pump,
momentarily remove the FILTER (1) from
the Inlet PIPE (2). If the motor speeds up
or the outlet pressure shown on GAUGE
(5) increases, the filter needs replace-
ment.
2. Flush PUMP if necessary
Should dirt, foreign particles, moisture or
oil be permitted to enter, the vanes will
become sluggish, resulting in a lowering of
outlet air pressure. Flush the pump with
LOCTITE Safety Solvent. (DO NOT USE
KEROSENE).
Pump should be operated for at least a few
minutes every one to two weeks to reduce
the likelihood of rust film forming in the
rotor.
If pump remains idle in humid environment
for some time, FLUSHING may be required
to remove rust film in chamber and rotor
slots.
11

Use the following directions to flush pump:
a. Turn-off Throttle Valve (10) to stop the
pump before flushing.
b. Before flushing, disassemble and
remove the following parts from the
pump:
- Respirator air supply hose(s)
- Inlet Filter and Pipe Stand
- Outlet Filter Jar and Outlet Filter
c. With the pump running, pour several
teaspoons of solvent into the pump’s
inlet port. Repeat the flushing if neces-
sary.
WARNING: Run the pump for a sufficient
time to purge all traces of the solvent
before replacing the filters, reconnecting
the air supply hose(s) and using the
respirator.
3. AVOID EXCESSIVE SPEEDS and
PRESSURE
- Avoid running above the 25 psig range
for any length of time.
NOTE: NEVER lubricate this oil-less pump
(ONLY THE AIRMOTOR CAN BE LUBRI-
CATED). BEARINGS are grease packed
and sealed. They require no further
lubrication.
Ensuring Pump Performance
To make sure your pump will perform properly:
1. Always locate the pump's Air INLET in a
clean, breathable air environment.
2. DO NOT contaminate inlet air with exhaust
air from air motor
3. Change OUTLET FILTER every 200 run-
ning hours.
4. Make sure RELIEF VALVE is fully seated
(no bleed-off).
5. Make sure LUBRICATOR is full and is
functioning (1 drop per minute).
6. Always check Respirator Air Supply Hoses
to make sure they are free of kinks.
7. Set incoming compressed drive air at 85
psig or higher. Set output air pressure as
specified in respirator owner’s manual.
See charts on pages 1 and 2 for pump perfor-
mance. If operating hood with Frigitron
2000 Series air conditioner, incoming com-
pressed driven air must be set at 95 psig or
higher.
