GENERAL INFORMATION
The Ambient Air Pump is designed to intake fresh, clean air from a non-contaminated atmosphere and supply this fresh air to a
continuous flow supplied air respirator.
The clean air is filtered through a porous plastic intake muffler designed to protect the pump from dust and dirt particles. The outlet air
supplied to the respirator is filtered through an activated charcoal filter designed to remove tastes and odors from the breathing air.
MST’sAmbientAirPump is oil-less and has rotary carbon vanes. The pump does not produce carbon monoxide, oil vapors, oil mist
or moisture, however it is extremely important that the atmosphere from which the air is drawn into the pump is clean and free of any
carbon monoxide or other toxic gases or vapors. In Canada, the Canadian Standards Association defines breathing air requirements
under CSA Z180.1; refer to “Breathing Air Requirements” within this manual. This standard includes direction regarding the
installation, commissioning, and maintenance of ambient air pump systems.
The Ambient Air Pump will supply a maximum air flow rate of ten (10) SCFM of breathing air to one worker or a maximum supply
pressure of fifteen (15) psig. USE ONLY MSHA/NIOSH APPROVED RESPIRATORS THAT WILL OPERATE AT
PRESSURES LESS THAN FIFTEEN (15) PSIG.

ASSEMBLING THE AMBIENT AIR PUMP
Remove the cardboard shipping sleeve around the pump and the gauge box. Lift the pump and attached plywood base from the
box and remove pump from plywood base.
MST recommends saving all packaging materials in the event that the pump must be shipped in the future.
Remove the pressure gauge from its box and assemble it to the gauge port located on
top of the pump’s filter manifold as shown in Figure 1. Tighten the gauge using a
suitable wrench. Teflon tape is recommended to prevent excessive tightening that
might be required to seal the gauge threads. The gauge should be rotated such that the
pressure scale can be easily read by the operator.
FIGURE1
Unscrew the pump’s aluminum filter can and check that the filter element is screwed
into the filter manifold properly. HAND TIGHTEN ONLY. Excessive force may
damage the filter element or threads. Replace the filter can and tighten securely
making sure the filter can seals on the filter can gasket (see Figure 2).
FIGURE 2
Check to make sure that the pressure relief valve, filter can, pressure gauge and outlet coupling are assembled tightly to the pump
to avoid air leakage.

OPERATING INSTRUCTIONS
WARNING:THERESPIRATORUSERMUSTNOT ENTERTHECONTAMINATEDWORKAREAUNTILALL OF
THE FOLLOWING STEPS HAVE BEEN COMPLETED.
Analyze the atmosphere at the location of the air inlet and the pump to be sure the pump will not be operating in a contaminated or an
explosive atmosphere.
Plug the pump into a 115 VAC grounded electrical outlet fused at 15 amps. The pump’s motor is equipped with a
toggle switch and 10 foot grounded cord with a standard three-prong plug. You may use up to 30 metres (100 feet)
of 15 amp, 3-wire grounded extension cord to reach your electrical outlet. Avoid excessive lengths of extension cord,
especially if running the pump continuously. We recommend using a minimum 12-gauge extension cord.
The pump will operate sitting on its four rubber mounts. It does not need to be
bolted down, however if desired, the pump may be mounted on a wall or ceiling as
long as the shaft center line is horizontal.
Make sure the pump’s inlet muffler is located in a clean, uncontaminated location
where breathable air is assured at all times (see Figure 3). Refer to CSA Z-180.1
for direction on pump installation and commissioning.
FIGURE 3
If the inlet muffler cannot be located in a clean breathable location, extension hoses are available to allow the inlet muffler to reach a
clean breathable location. See the instructions supplied with the extension hose for assembly instructions. You may connect up to
three (3) extension hoses together with the original inlet hose, to achieve a maximum distance of one hundred (100) feet. For greater
distances, install rigid, smooth bore, plastic piping having an internal diameter of not less than 1.5 inches. Use good engineering
practices to ensure that the inlet piping system does not affect pump performance.
Assemble your respirator according to the manufacturer’s instructions . Be sure pump’s outlet pressure, measured at the pressure
gauge, is greater than the minimum MSHA/NIOSH approved pressure required to operate the respirator. This pressure should be
measured when all components of the respirator (hoses, breathing tubes, etc.) are connected to the pump and the pump is operating.
The respirator’s approved pressure requirementswill be located in the respirator’s instruction manualand/or on labels attached to the
respirator.
Questions regarding whether or not your Respirator is compatible with this pump can be directed to 3M Canada’s Occupational
Health and Environmental Safety Hotline at 1-800-267-4414.

10
Should the air pressure require adjustment, loosen the locknut on the pressure relief
valve and adjust the top sleeve to achieve the proper pressure (see Figure 4).
Clockwise will increase the pressure, counter-clockwise will decrease the pressure.
Re-tighten the locking nut when adjustment is complete to prevent inadvertent changes
to the adjustment. The pressure relief valve may vent in order to prevent the pump
from exceeding the recommended pressure. This is normal as long as the pressure on
the gauge is correct for the respirator used.
FIGURE 4
DO NOT ADJUST THE PRESSURE RELIEF VALVE TO ALLOW THE PRESSURE TO EXCEED 15 PSIG MAXIMUM.
PUMP DAMAGE WILL OCCUR AND THE WARRANTY ON THE PUMP WILL BE VOIDED IF THE PUMP IS
ALLOWED TO OPERATE ABOVE 15 PSIG PRESSURE.
Allow the air to purge through the respirator and hose assembly for a few minutes to eliminate any odors or tastes in the respirator
assembly. Donthe respirator and re-check the outlet pressure gauge prior to entering the contaminated work area.
When finished working, exit 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.
Refer to the respirator’s instruction manual for proper inspection, maintenance and storage procedures for the respirator.
Warning: Do not use extension cords longer than 30 metres (100 feet) or rated
less than fifteen (15) amperes when operating this device. We recommend using
a minimum 12-gauge grounded extension cord with a length not exceeding 30
metres (100 feet). Pump damage will occur and the pump's warranty will be
voided if this practice is not followed.

THE AMBIENT AIR PUMP BECOMES VERY HOT DURING CONTINUOUS OPERATION AND CAN CAUSE BURNS.
TURN PUMP OFF, DISCONNECT FROM ELECTRICAL OUTLET AND ALLOW TO COOL BEFORE PERFORMING
ANY MAINTENANCE ON THE PUMP.
Regular inspection can prevent unnecessary damage and repairs. Intake muffler and outlet filters require periodic inspection and
replacement. Initial inspection is suggested at 100 hours of operation, then the user should determine frequency. Keeping filtersclean
can prevent most problems. Dirty filters decrease unit performance and can decrease unit service life. WARNING: FAILURE TO
COMPLY WITH THE FILTER CHANGE SCHEDULE LISTED BELOW, CAN RESULT IN CONTAMINATED
BREATHING AIR. UNFIT BREATHING AIR CAN CAUSE SERIOUS INJURY OR DEATH.
REPLACE THE INLET MUFFLER AND OUTLET FILTER REGULARLY
Dirty filters may inhibit air flow to the respirator and cause the motor to overload and decrease vane life.
Replace the outlet filter (P/N 80496) at least once every 200 hours of operation or sooner if necessary.
Replace the inlet muffler (P/N 80515) at least once every 500 hours of operation or sooner if necessary.
WARNING:INLET MUFFLERAND OUTLETFILTER SHOULDBE REPLACED. DONOT ATTEMPTTO CLEAN
THESE FILTERS. SOLVENTS AND CLEANING SOLUTIONS CAN CONTAMINATE BREATHING AIR AND
DEATH OR SERIOUS INJURY COULD RESULT.
FLUSH PUMP IF NECESSARY
Should excessive dirt, sand, foreign particles, moisture or oil be permitted to enter the pump, the carbon vanes willbecomesluggish
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 compression chamber
and the rotor slots. This will result in decreased outlet pressure or a failure to operate.
If the above occurs, the pump should be flushed with the following recommended solvent:
Loctite ODC -Free Cleaner & Degreaser (P/N 22355).
WARNING: NEVER USE KEROSENE OR OTHER COMBUSTIBLE LIQUIDS OR VAPORS WITH THIS PUMP.
THEIRUSE MAYRESULT INAN EXPLOSION WHICHMAY CAUSEINJURY OR DEATH. THEVAPORS MAY
BE TOXIC, AND IF NOT COMPLETELY REMOVED, MAY CONTAMINATE THE
BREATHING AIR AND RESULT IN DEATH OR SERIOUS INJURY.

Flushing the pump requires (2) 3/8" normal pipe thread (NPT) pipe nipples at least 4" long.
Remove all muffler and filter elements and remove inlet and outlet end cap assemblies from pump housing (refer to Figure 5 to correctly
identify end cap assemblies).
Insert 3/8" pipe nipples through openings in Muffler box and thread into ports where end cap assemblies are threaded. HAND
TIGHTEN ONLY.
WARNING: WEAR EYE PROTECTION AND FLUSH PUMP IN A WELL VENTILATED AREA.
With pump running, spray safety solvent directly into inlet port for approximately 5-10 seconds. While adding solvent, listen for
changes in motor sounds in unit.
If motor sounds smooth out, plug inlet port for 20-30 seconds and then release vacuum. Repeat this procedure three or
four times, each time spraying solvent into pump for 5-10 seconds.
When complete, run the pump for several minutes until all traces of solvent are gone and there are no noticeable odors. Reassemble
pump and install new outlet filter.
WARNING:RUN THE PUMPFOR A SUFFICIENTTIME TO PURGE ALLTRACES OF THESOLVENT BEFORE
REPLACING FILTERS, RECONNECTING THE AIR SUPPLY HOSE AND USING THE RESPIRATOR.

TROUBLE SHOOTING INFORMATION
If your Ambient Air pump is not working satisfactorily, please follow the trouble shooting steps below:
SYMPTOM: Pump Fails to Start or Hums
Turn pump switch off and disconnect from the power source.
Check for correct electrical current as shown on the motor plate and in the Specification Chart on page 3 of
this manual.
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.
Wait 15 minutes and restart
SYMPTOM: Outlet Pressure Too Low
Be sure you know the proper pressure range for the respirator -see the respirator’s instruction manual.
Be sure the respirator and air supply hose are connected when the gauge reading is taken.
Check to see that the gauge is functioning properly. Replace the gauge if broken or malfunctioning.
Check to see that the outlet filter can is seated firmly into the filter housing’s gasket so that no air can escape.
Replace can and/or gasket if damaged or worn.
Check to see that no air is escaping from the pressure relief valve. Re-adjust the pressure relief valve if
necessary.
Check that both the inlet muffler (P/N 80515) and the outlet filter (P/N 80496) are clean and replace if
necessary. Dirty filters restrict air flow.
Flush the pump with Loctite ODC -Free Cleaner & Degreaser (P/N 22355) to remove excessive dirt,
sand, particles, moisture or oil in the rotor assembly. See the Maintenance Section on Page 11 of this
manual for the procedure on flushing the pump.
When the parts are reassembled, attach the respirator and turn on the pump, monitoring the outlet pressure.
SYMPTOM: Outlet Pressure Too High
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.
Check the respirator’s air supply hose for kinks.

15
SYMPTOM: Pump Overheating
71°C –90° C (160°F –195°F) is normal output air temperature when the pump is continuously running.
This heat is dissipated as it travels through the respirator’s air supply hose until it reaches ambient air
temperature.
Make sure that both the inlet muffler and outlet filter are clean. Replace if necessary.
The pressure relief 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.
Flush the pump with Loctite ODC -Free Cleaner & Degreaser (P/N 22355) to remove excess dirt, sand,
particles, moisture or oil in the rotor assembly. See the Maintenance Section on page 11 of this manual for
proper directions on flushing the pump. When parts are reassembled, attach the respirator and turn the
pump on, monitoring its performance and overheating.
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 the circuit.
SYMPTOM: Outlet Air Temperature Too Warm
Be sure that the air supply hose is laid out (not coiled) to permit excess heat to dissipate from the hose
Keep the air supply hose out of direct sunlight and off warm or hot surfaces.
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
Let the pump warm up approximately 15 minutes before using.
Coil the first 25-50 feet of air supply hose closest to the pump.
Keep the air supply hose off cold surfaces.
SYMPTOM: Moisture In Air Supply Hose Line
Locate the air inlet muffler in a dry, clean air location, where breathable air can be assured at all times.
With the air supply hose connected to the pump and a suitable quick-connect plug installed in the respirator
end of the supply hose (do not connect the respirator), turn the pump on and run for approximately 15
minutes to purge the hose of excessive moisture.
