SAFETY PRECAUTIONS
FOLLOW ALL WARNINGS AND CAUTIONS
ALL PUMPS:
DO NOT place oil-less air pump in an area that cannot GUARANTEE clean Grade D breathable air, per OSHA 29
CFR 1910.134 to the AABA inlet. See below for Grade D requirements.
DO NOT attempt to service the air pump while it is running or while it is connected to electrical or air power.
DO NOT oil or lubricate the pump.
DO NOT kink power cord and never allow the cord to come in contact with oil, grease, hot surfaces, or chemicals.
DO NOT use ungrounded electrical receptacles.
DO NOT use undersized electrical extension cords or wiring.
DO NOT use the pump as an air-filtering device for vapors, gases, or particulates.
DO NOT start pump without respirator(s) and hose(s) connected to pump.
DO NOT use Vortex type cooled respirators with Allegro pumps.
DO check all airline hoses for weakness and wear before use.
DO Ensure that all hose and plumbing connections are secure.
DO Ensure that the power source conforms to the requirements of your equipment.
DO remove aluminum canister on exhaust filter assembly and check that exhaust filter is firmly seated in
place before startup.
AIR DRIVEN PUMP: (P/N 9850)
DO NOT attempt to service the air pump or air motor while it is in operation, and air source connected.
DO NOT run air motor with less than 75 cfm at 80 psi.
DO NOT run air motor with dirty particulate filter.
DO run air motor with inline lubrication properly filled and adjusted.
DO make sure that the air pressure and volume conforms to the requirements of your equipment.
EXPLOSION PROOF PUMP: (P/N 9833)

USER’S
INSTRUCTIONS
1) Ensure that the pump (or inlet extension filter) is in a clean uncontaminated air environment.
o If clean air CANNOT be guaranteed at the pump inlet at all times, use the Inlet extension hose kit
(P/N: 9700-65). See instructions on the Inlet extension kit below.
2) Ensure canister on the discharge filter assembly is firmly seated and secure before startup.
o Discharge air passes through the HEPA outlet filter located inside the discharged filter assembly.
o HEPA filter is NOT for use as protection against vapors and gases.
o D.O.P. efficiency: 99.97% (0.3-0.6 micron particles)
3) Attach respirator/hood and air breathing hose to pump.
o Check respirator manufacturers’ recommendation for inspection/operation procedures.
o Never start pump without hose and respirator attached.
o This may result in excessive back pressure that will lead to pump damage.
4) Ensure that air hoses are not tightly coiled or kinked.
o This may cause some restriction of the air flow causing the pump to run at a higher PSI and overheat.
5) Plug the pump into proper electrical outlet and turn on the power switch.
6) Properly adjust pressure relief valve. (see instructions for PRV below)
o Pumps are designed for multiple users and may require an adjustment to the pressure relief valve to fit the
number of workers using the system.
7) Don the respirator as instructed per manufacturer user’s instructions.
8) Ensure all users are receiving sufficient air to the respirator.
o Use Allegro P/N 9900-40 “Flow test kit” to verify proper airflow (CFM) to the respirator.
o Ambient air pump gauge indicates the dynamic air pressure (back pressure), NOT air volume.
9) Enter work/contaminated area.
PRESSURE RELIEF VALVE (RPV):
1) Before making any adjustments check with the respirator manufacturer for the required CFM to that specific
respirator.
2) To adjust the relief valve, loosen the lock nut.
3) Turn the adjustment knob counterclockwise to "bleed-off" air.
o This will decrease pump output to the respirators.
o It is important to set the proper air flow to the respirator, too much air will over work the pump motor,
causing it to overheat. Too little air will not provide sufficient air to the user.
4) Turn the adjustment knob clockwise to decrease air being bled off.
o This will increase the pressure and air flow to respirators.
o Care must be taken to ensure that the respirator and air hose are not disconnected while pump is running,
when the PRV is set to this setting. Pump damage will occur.
5) Tighten lock nut.
o PRV must be readjusted each time the number of users, respirator type or length of air hose is changed.
INLET EXTENSION KIT: (P/N 9700-65)
1) Locate the inlet filter where breathing air CANNOT be contaminated by harmful vapors, gases, or particulate
and where it will be protected from excessive moisture.
o Inlet hose extensions may be used to increase distance from the inlet filter to the pump up to 250 feet.
o With the use of remote Inlet Extension Hose(s), noise level at the pump is greatly reduced.
o The noise will be transferred by the hose to wherever the Inlet Filter is located.
o Respirators must be supplied with clean breathable air at all times, per OSHA 29CFR 1910.134.
2) In order to achieve this requirement, it may be necessary to use the inlet extension to reach a clean air
environment.
3) Remove the inlet filter assembly from the pump.
4) Install inlet extension hose to the pump inlet port, using the supplied reducers/ adapters.
5) Install the inlet filter assembly on the other end of the extension hose.
o The A300 pump will require an inlet filter assembly (P/N: 9700-08) for use with the extension hose.
6) Place the extension hose in a clean, uncontaminated environment.

TOLERANCES AND WARNINGS
Allegro ambient air pumps are precision pumps that have only .0015-.003 clearance between the top of the rotor and
cylinder bore, and .003 or less clearance between end of the rotor and the end plate. Any thrust on the shaft such as
mishandling or dropping the pump on its end will tend to close these clearances, causing the rotor to jam. Foreign
particles, excessive dirt or dust build up may cause sluggish performance and eventual “jamming” of the pump. The
pumps have carbon vanes and grease packed bearings. They MUST NOT be lubricated or flushed with petroleum
base solvents.
All models have precision ground vanes inside the pump that take up their own wear and will last approximately
3,000 hours, depending upon workload, maintenance, speed and degree of pressure. Excessive dirt, foreign
particles, or moisture could cause the vanes to stick in the rotor slots and even break. Periodic “flushing” could
prevent this. Use the Allegro flushing cleaner (P/N: 9700-65) in the pump chamber only.
CAUTION!
The basic materials used in the pumps are cast iron and steel. Consequently, any moisture will tend to corrode the
interior, especially when pump stands idle for extended periods.
AIR PUMP: (9850)
o The motor for the Air driven pump is a precision built rotary-type motor. The vanes for this motor take up their
own wear and will last 5,000 to 15,000 hours depending upon speed, operating pressure, and the precautions
taken in maintaining the motor.
o The type of shaft seal used does not lend itself to operating pressures above 100 psi (6.89 bar).
o The air motor requires a minimum of 75 cfm at 80 psi inlet pressure and volume to operate pump.
o The starting torque is less than the running torque and could vary depending on the position at which the vanes
stop in relation to the air intake port.
o The speed and torque can be regulated by using the pressure regulator or shut-off ball valve to obtain desired
power.
EXPLOSION PROOF PUMP: (9833)
• The Ambient air pump is rated for use in hazardous locations, however the user must ensure that the following
guidelines are followed:
o The inlet filter (or Extension) must not be in a hazardous environment; this will endanger the respirator
user. Inlet filter must be in a clean uncontaminated environment at all times.
o Testing of ambient location where inlet filter is placed is strongly recommended, to ensure it meets CGA
specifications of grade D or higher.
• The pump is rated to be used in the following hazardous locations:
o Class I, Group D
o Class II, Group F and G
• Verify your location classification.
o Ensure the pump design meets the hazardous class and group classifications of job site.
o The National Electric Code divides these locations into Classes and Groups according to the type of
explosive gas/agent, which may be present.
o For specific information, consult the National Electric Code, Section 500.
• The Hazardous Location plug and receptacle must be used to hardwire the pump to the power source. Consult a
qualified electrician and the National Electric Code articles 500 through 517.
CAUTION!
Hazardous location equipment may be required in any area where the presence of flammable gases, vapors or finely
pulverized dusts in the atmosphere is sufficient to create a threat of explosion or fire. It may also be required where
easily ignitable fibers of flyings are present.

INSPECTION
ALL PUMPS:
Regular inspection, cleaning filters, and “flushing” may prevent extensive repairs. Dirty or clogged filter elements
can cause overheating (in excess of 200°F) and possible pump failure.
It is normal for the pump surface and immediate output air temperatures to reach 200°F when the unit is run
continuously under a heavy load or high pressure settings.
o If there is evidence of overheating or excessive noise, stop immediately.
o High-pressure operation will shorten pump’s life.
o Keep external surfaces clean for proper heat dissipation.
o Do not allow pump to operate in ambient air temperatures excess of 40°C (104°F).
Failures due to pressure buildup are due to the following:
o Improper setting of pressure relief valve
o Leaks in airline connections
o Damaged filter canister threads
o Collapsed or kinked air lines, dirty filter elements
o Vanes sticking in the rotor slots
ELECTRICAL MOTORS:
Some electrical motors are equipped with a thermal protector that shuts motor down automatically when subjected
to mechanical or electrical overloads. Ensure electrical power source corresponds to what is on the motor name
plate.
AIR DRIVEN MOTORS:
The air coming out of the discharge port will cool as it expands. It is important that the PVC extension (included
with the blower) is used to extend the muffler from the motor discharge port. This will help prevent ice from
forming on the muffler due to moisture in the air.

MAINTENANCE
FILTERS:
• Change inlet filter every 200 running hours or if the pressure gauge shows a drop in pressure.
• Change discharge filter every 200 running hours or if the pressure gauge shows an increase in pressure.
FLUSHING INSTRUCTIONS:
1. Perform this procedure in a well ventilated area.
2. Wear solvent resistant gloves and eye protection while performing the flushing procedure.
3. Disconnect airline hose and respirator to prevent contamination.
4. Remove inlet filter assembly and pressure relief valve, to prevent damage to pump from back pressure.
5. Add 10-15 squirts of flushing solvent, Allegro P/N: 9700-11, through the inlet port opening.
6. Turn pump on and let run for 1 minute to flush out contaminants.
7. Repeat flushing procedure if pump is in extremely dirty or is under performing.
8. Replace inlet filter assembly and pressure relief valve.
9. Replace exhaust filter and inlet filter.
10. Reconnect airline hose and respirator, do not use respirator until all steps are complete.
11. Turn pump on for 10 minutes, this allows the flushing solution to dry out completely.
AIR DRIVEN MOTOR: (P/N 9850)
1. Disconnect inlet plumbing from pump and muffler assembly.
2. Add 10-15 squirts of solvent into the inlet port.
3. Rotate the shaft by hand in both directions for a few minutes.
4. Reassemble plumbing and reconnect the inlet air supply line and slowly apply pressure.
5. Flushing liquid should slowly exit the exhaust port, let run for 10 minutes
6. Reassemble exhaust assembly.
WARNING!
Keep face away from exhaust port. DO NOT flush unit with KEROSENE OR OTHER COMBUSTIBLE
LIQUIDS. Personal injury and/or property damage will result.
LUBRICATION: (For Air Driven Pump Only P/N: 9850)
To lubricate the air motor (which drives air driven Model: A-400AD), use a detergent SAE #10 automotive engine
oil. DO NOT lubricate air pump. For proper operation and maximum service-life, an automatic air line lubricator
has been installed inline just before of the air motor.
• The lubricator should be adjusted to feed one drop of oil per minute.
• Lubrication is necessary for all internal moving parts and rust prevention.
• Excessive moisture in the air line can cause rust formation in motor and might also cause ice to form in the
muffler due to expansion of air through the motor.
• The moisture problem can be corrected by installing an additional moisture separator inline.
VANE REPLACEMENT: (Consult factory prior to replacing vanes.)
To replace vanes or inspect the pump interior:
1. Remove only the endplate by removing the six bolts holding the end plate to the body.
2. Remove the endplate and the four vanes, pay attention to the direction the vanes are facing.
3. Do not remove the rotor or loosen any electric motor “through-bolts.”
4. Inspect used vanes for signs of cracking due to backpressure.
5. Inspect interior surface of chamber and rotor, for any signs of scaring or metal to metal contact.
6. Ensure surface is smooth and free of rust or contaminants, sand down surface if needed.
7. Clean with appropriate flushing solution.
8. If necessary align body to set proper clearance.
9. Insert the vanes with the beveled edge fitting the contour of the body bore of the pump.
10. The rotor should be turned while setting clearance to assure that all points on the rotor clear the body.
11. Replace the endplate and endplate bolts securely. (Do not over-tighten).
