GENERAL INFORMATION
Bullard Free-Air®pumps transfer ambient air from a clean air location, where
breathable 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 pro-
duce 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.
The pumps will supply air to one, two or three workers depending on the
pump model and style of respirator(s) being used. The chart below describes
the pump model, the number of respirators each unit will supply and its
maximum outlet pressure.

�WARNING
READ ALL INSTRUCTIONS IN THIS MANUAL BEFORE USING FREE AIR®PUMP MODELS EDP-10, EDP-16-TE OR EDP-16-HAZ.
FAILURE TO OPERATE ANY OF THESE PUMPS 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 clean breathable air location at all times. THE PUMP DOES NOT REMOVE TOXIC GASES OR OTHER CONTAMINANTS FROM
THE INCOMING AIR IT TRANSFERS TO THE RESPIRATOR WEARER.
See the BREATHING AIR REQUIREMENTS section on page 4 for specific details on breathing air quality. THESE PUMPS DO NOT SUPPLY OXYGEN.
2. This pump will only supply the required volume of air [6-15 cfm (170-425 lpm) for hoods or 4-15 cfm (113-425 lpm) for tight fitting half or full face masks] to
low pressure continuous-flow supplied-air respirators approved by MSHA/NIOSH to operate at less than 15 psig (103 kPa).
Be sure that the pump’s outlet pressure, measured by the pressure gauge on the pump, is maintained above the minimum pressure setting required by the
respirator manufacturer.
To be assured your respirator can be used with this pump refer to:
a) The Pump Specification Table on page 1 for the maximum outlet pressure of the pump model you are using.
b) The section in the respirator’s instruction manual for the respirator’s approved pressure range and permissible air supply hose lengths.

Operating the Free-Air Pump
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 air inlet and the pump itself
to be sure the pump will not be operating in a contaminated or an explosive
atmosphere.
2. If Using an EDP10 Pump:
Plug the pump into a 115 volt electrical outlet. The pump’s motor is equipped
with a toggle switch and a 7 foot (2 m) grounded cord with a standard three-
prong plug.
If using the EDP10HM, no additional set up is required for the run hour meter
to operate.
For extension cords, 12 AWG (15 amps) or heavier duty gauge is recommend-
ed. Bullard also recommends that the distance be limited to 100 feet, the plug
be three-prong grounded, and that only one extension cord be used.
Plug the pump into a 220 volt electrical outlet.
If Using an EDP16TE Pump:
Plug the pump into a 115 volt electrical outlet. The pump’s motor is equipped
with a toggle switch and a 7 (2 m) foot ground-ed cord with a standard three-
prong plug.
You may use up to 100 (30.5 m) feet of 50 amp, 3-wire grounded extension
cord to reach your electrical outlet. We recommend using 12 gauge wire.
Avoid excessive lengths of extension cord, especially if running the pump
continuously.
The pump’s motor is equipped with manual reset thermal overload protection
for 115 volt operation. The reset button is located on the side opposite the
toggle switch.
The EDP16TE may be rewired for 208/230 volt, 60 Hz operation. If rewired to
208/230 a suitable starter/contactor and thermal overload protector must be
provided by the user. The conversion work should be performed by a qualified
electrician.
If Using an EDP16HAZ Pump:
The EDP16HAZ must be wired for either 230 or 460 volt, 3-phase, 60 Hz
operation.
THE USER MUST SUPPLY AN EXPLOSION-PROOF THERMAL OVERLOAD
PROTECTOR AND A STARTER/CONTACTOR SWITCH.
Proper wiring should be performed by a qualified electrician.
REFER TO THE MOTOR NAME PLATE OR JUNCTION BOX COVER FOR PROPER
WIRING DIAGRAM.
�WARNING
PROPER MOTOR SELECTION AND WIRING (IN ACCORDANCE WITH LOCAL
AND NATIONAL ELECTRIC CODES) IS THE RESPONSIBILITY OF THE USER.
3. Each pump will operate sitting on its four rubber mounts. It does not need
to be bolted down. If desired, the pump may be mounted on a wall or ceil-
ing as long as the shaft center line is horizontal.
4. Make sure the pump’s inlet
filter is located in a clean,
uncontaminated location
where breathable air is
assured at all times (see
Figure 3).
If the inlet filter can-
not be placed in a clean
breathable location, install
Bullard’s 50 foot (15 m)
Inlet Extension Hose Kit
(Cat. No. V50IN) to the
pump’s inlet port. See the
directions shipped with
the Extension Hose Kit for
assembly instructions.
If clean breathable air cannot be guaranteed at all times within this 50 foot
(15 m) reach, you may add up to five (5) additional lengths of 50 foot (15 m)
Extension Hose (Cat. V50EX).
Therefore, you may place your inlet filter up to 300 feet (91.4 m) (6 x 50)
away from the pump. Do not add more than 300
(91.4 m) feet of inlet extension hose to
the pump.
5. 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 pressure will be found in the respira-
tor’s instruction manual and/or on labels attached to the respirator.
If you have any questions as to whether or not your respirator is compat-
ible with this pump, call Bullard’s Customer Service Department at 1-800-
827-0423 or 1-859-234-6616.
6. Connect the respirator’s NIOSH approved air supply hose(s) to the quick-
disconnect outlet coupler(s) on the pump (see Figure 4).

A. OUTLET COUPLER
SPLITTER ADAPTOR
If the respirator’s air supply
hose(s) have 1/2” Industrial
Interchange quick-disconnect
fittings and you want to sup-
ply air to one of the following:
- TWO Half or Full Face
Mask respirators us-
ing pump model EDP10/
EDP1050HZ220V
or
- THREE Half or Full Face Mask respirators using pump model EDP16TE or
EDP16HAZ
Connect the following Q.D. coupler splitter adaptor to the pump (see
Figure 5):
Cat. No. V24 - Double Outlet, One Flow-Through (GREEN) & One Shut-Off
(RED).
B. CONNECTING AIR SUPPLY
HOSE(S) WITHOUT 1/2”
QUICK-DISCONNECT
FITTINGS
If your respirator’s NIOSH
approved air supply hose
will not attach to the pump’s
standard 1/2” Industrial
Interchange outlet coupler,
(see above) you can adapt
your hose’s fitting to the
pump by converting the
pump’s quick-disconnect
outlet to 3/8” Female NPT
with the installation of one of
the following adaptors (see Figure 6):
Cat. No. V22 - Converts SINGLE outlet to DOUBLE 3/8” female NPT pipe
thread.
Cat. No. V23 - Converts SINGLE
outlet to SINGLE 3/8” female
NPT pipe thread. A variety of
quick-disconnect fittings may be
used to connect your air supply
hose to the 3/8” female pipe
thread. Contact your respira-
tor’s manufacturer for the
proper fitting (Hansen, Foster,
Snap-Tite, Schrader, etc.) (see
Figure 7).
7. 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 accumulated
inside the hose.
TIP: If pump is turned on without a repirator attached, the gauge will
read zero because the gauge reads back pressure.
8. Connect the respirator to the air supply hose using the quick-disconnect
fittings.
9. With the air flowing, put on the respirator by following the directions in
the respirator manufacturer’s instruction manual.
10. Set the pump’s outlet pressure to within the respirator’s approved pres-
sure range by adjusting the pressure adjustment valve located on the
outlet filter body.
To set the pressure adjust-
ment valve, loosen the lock
nut. Once the desired outlet
pressure has been obtained,
retighten the lock nut firmly
by hand to maintain consistent
outlet pressure. (see Figure 8).
YOU ARE NOW READY TO
ENTER THE WORK AREA.
11. When finished working, leave
the work area wearing the
respirator with the air still
flowing. Once outside the contaminated area, remove the respirator,
turn the pump off, then disconnect the air supply hose using the quick-
disconnect couplers.
See the respirator’s instruction manual for proper inspection, maintenance and
storage procedures for the respirator you are using.

Maintaining the Free-Air Pump/Troubleshooting Guide
Maintaining the Free-Air®Pump
Bullard Free-Air pumps consist of an electrically driven air pump with four
carbon vanes. The vanes self-adjust as they wear and should last from 5,000
to 15,000 hours if properly maintained.
For the pump to operate at its optimum performance level, the following
routine maintenance procedures must be performed:
1. REPLACE THE INLET AND OUTLET FILTERS REGULARLY
Dirty filters may inhibit air flow to the respirator(s), and cause the motor to
overload and decrease vane life.
- Replace the Carbofine outlet filter cartridge (Cat. No. S17101) at least once
every 200 running hours or sooner, if necessary.
- Replace the inlet filter (Cat. No. 23611) at least once every 500 operating
hours or sooner, if necessary.
2. FLUSH PUMP IF NECESSARY
Should excessive dirt, sand, foreign particles, moisture or oil be permitted
to enter the pump, the carbon vanes will become sluggish and the pump’s
performance will deteriorate. This will result in decreased outlet pressure or
failure of the pump to operate.
If the pump remains idle in a humid environment for a long period of time,
rust film may build up in the pump’s chamber and rotor slots. This will result
in decreased outlet pressure or a failure to operate at all.
If the above occurs, the pump should be flushed with the following
recommended solvent:
- Loctite Safety Solvent (Cat. No. S17931)
�WARNING
NEVER USE KEROSENE OR OTHER COMBUSTIBLE LIQUIDS OR VAPORS WITH THIS
PUMP. THEIR USE MAY RESULT IN AN EXPLOSION WHICH MAY CAUSE INJURY OR
DEATH.
Directions for Flushing Pump
a. Before flushing, disassemble and remove the following parts from the
pump:
- Disconnect the respirator’s air supply hose
- Remove the pump’s inlet filter
- Remove the pump’s outlet filter jar and outlet filter cartridge
b. With the pump running, pour several ounces of approved safety solvent
into the pump’s air inlet port. Repeat the flushing if necessary.
�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. IN EVENT OF BROKEN VANES
Should you experience broken vanes in your Free-Air pump, it is important to
thoroughly clean out not only the rotor and drum, but also the inlet and outlet
filters.
Before cleaning
- Disconnect pump from power source
- Disconnect respirator’s air supply hose
- Remove the pump’s inlet filter
- Remove the pump’s outlet filter jar and outlet filter cartridge
- Remove the end plate which covers the rotor and drum
Remove any large pieces of vane which may still be located in the vane slots,
located on the rotor.
Next, tilt pump forward towards the ground (in the direction of the quick-
disconnect coupler), being careful not to impact ground, and allow any unseen
dust and debris to fall out of the pump. Jiggling and shaking to aid removal is
acceptable.
Use a can of compressed air, or a compressed air tool to spray air through
the air inlet port. Do the same in and around the rotor and drum, ideally
while in a forward tilted position to aid in removal. Finally, apply compressed
air to the outlet filter housing.
Repeat steps as necessary, until no further debris is emitted.
After no further debris is present, turn the rotor by hand in a clockwise
direction to ensure that the rotation is smooth, with no audible or felt grinding
or resistance. If grinding or resistance is felt, re-apply compressed air.
4. AVOID RUNNING THE PUMP AT EXCESSIVE PRESSURE
Avoid running the Free Air pump above 15 psig (103 kPa) for any length of
time. Running the pump above 15 psig (103 kPa) could cause motor damage
and will create premature wear of the carbon vanes.
NOTE
NEVER LUBRICATE THIS OIL-LESS PUMP. THE MOTOR BEARINGS
ARE GREASE PACKED AND SEALED. THEY REQUIRE NO FURTHER
LUBRICATION.
Free-Air Pump Trouble Shooting Guide
If your Bullard Free-Air pump is not working satisfactorily, please follow the
trouble shooting steps below:
Initial Checklist
1. You should be using Bullard V20 hose for Free-Air Pumps.
2. If using an extension cord, Bullard recommends 15 amp, 3-wire, 12 AWG
grounded extension cord up to 100 feet. Do not overload the circuit with
additional electrical equipment. The EDP10 requires at least a 7 kw
generator and the EDP16TE requires at least a 12 kw generator.
3. If using a Bullard cool tube, only the Frigtron 2000 is approved for the
EDP30 and ADP20. All other Free-Air Pumps do not support cool tubes.
SYMPTOM: Pump Fails to Start or Hums
1. Turn pump switch off and disconnect from the power source.
2. Check for the correct electrical current as shown on the motor plate and in
the Electric Motor Specification Chart on page 7 of this manual.
3. The pump is equipped with a thermal overload protector that turns the
current off when subjected to electrical overloads. Check to be sure that
the circuit is not overloaded by the pump and other electrical equipment.
4. Check to make sure that the carbon vanes move freely. If stuck to the
housing wall then flush with Loctite Safety Solvent.
5. Wait 15 minutes and restart.

www.bullard.com
SYMPTOM: Outlet Air Pressure Too Low
1. Be sure you know the proper pressure range for the respirator - see the
respirator’s instruction manual.
2. Be sure the respirator and air supply hose are connected when the gauge
reading is taken.
3. Check to see that the gauge is functioning properly. Replace the gauge if broken
or malfunctioning.
4. Check to see that the outlet filter jar is seated firmly into the filter housing’s
O-ring so that no air can escape. Replace the jar and/or O-ring if damaged
or worn.
5. Check to see that no air is escaping from the relief valve in the outlet filter
body. Reset the pressure adjustment valve if necessary.
6. Check that both the inlet filter (Cat. No. 23611) and outlet filter (Cat. No.
S17101) are clean and replace if necessary. Dirty filters restrict air flow.
7. Flush the pump with Loctite Safety Solvent (Cat. no. S17931) to remove
excessive dirt, sand, particles, moisture or oil in the rotor assembly.
See the Maintenance Section on Page 7 of this manual for proper directions
on flushing the pump.
When the parts are reassembled, attach the respirator and turn the pump
on, monitoring the outlet pressure.
8. Check to make sure that the carbon vanes do not need to be replaced. Worn
vanes may not produce as much flow.
9. Make sure there is nothing obstructing the airline supply hose.
SYMPTOM: Outlet Pressure Too High
1. The pressure adjustment valve is set too high - reset to a lower pressure. Be
sure the outlet pressure remains in the proper range for the respirator as
specified by the respirator manufacturer - see the respirator’s instruction
manual.
2. Check the respirator’s air supply hose for kinks.
SYMPTOM: Pump Overheating
1. 160° - 200°F (71° - 93°C) is normal output air temperature when the pump
is conintuously running. This heat is dissipated as it travels through the
respirator’s air supply hose until it reaches ambient air temperature.
2. Make sure that both the inlet and outlet filters are clean. Replace if
necessary.
3. The pressure adjustment valve is set too high - reset to a lower pressure.
Be sure the outlet pressure remains in the proper range for the respirator
as specified by the respirator manufacturer - see the respirator’s
instruction manual.
4. Flush the pump with Loctite Safety Solvent (cat. no. S17931) to remove
excess dirt, sand, particles, moisture or oil in the rotor assembly.
See the Maintenance Section on page 7 in your user manual for proper
directions on flushing the pump.
When the parts are reassembled, attach the respirator and turn the pump
on, monitoring its performance for overheating.
5. The electrical circuit to which the pump is connected is overloaded.
Check the amperage load of the circuit and disconnect other electrical
equipment, if necessary, from that circuit.
TIP: If ambient air temperatures are high, place the Bullard Free-Air®
Pump in the shade. Do not lay air line hoses directly on blacktop. Also, be
sure all fittings are at least 1/2” ID.
SYMPTOM: Outlet Air Temperature Too Warm
1. Be sure that at least the first 50 feet (15 m) of air supply hose closest to
the pump is laid out (not coiled) to permit excess heat to dissipate from the
hose.
2. Keep the air supply hose out of direct sunlight and off warm or hot
surfaces.
3. Put a coiled section of the air supply hose in the bottom of a large
container. Fill the container with water and ice and cover with a lid. For
best results, locate the container as close to the worker as possible.
SYMPTOM: Outlet Air Temperature Too Cold
1. Let the pump warm up approximately 15 minutes before using.
2. Coil the first 25-50 feet (7.6-15 m) of air supply hose closest to the pump.
3. Keep the air supply hose off cold surfaces.
SYMPTOM: Moisture in Air Supply Hose Line
1. Locate the air inlet filter in a dry, clean air location, where breathable air
can be assured at all times.
2. With the air supply hose connected to the pump, but not the respirator,
turn the pump on and let it run for approximately 15 minutes to purge the
hose of excessive moisture.
3. Between uses, hang the hoses so extra moisture may drain.

Description
Air Filter Replacement Schedule
Regular inspection and replacement of the air filters will prevent extensive
and costly pump repair. Dirty or clogged filters can be responsible for failure
of the pump to build up outlet pressure and eventual overheating.
- Replace the Carbofine outlet filter (Cat. No. S17101) at least once every 200
running hours or sooner if necessary.
The outlet filter cartridge is multi-layered with 40-micron size particles of
activated carbon, a sorbent bed with an exposed carbon surface of more than
15,000 square feet (1,615 sq meters).
- Replace the medium efficiency inlet filter (Cat. No. 23611) at least once
every 500 running hours or sooner if necessary.
The inlet filter keeps moisture as well as particulates out of the air supply and
helps protect the pump’s carbon vanes.
We recommend the following chart be used to monitor and maintain a routine
air filter replacement schedule.
