A-4000AD
Ideal for use when electric power is unavailable or
undesirable. Highly effective in work areas where
large amounts of compressed air are available such
as sandblasting. Air driven motor is protected and
lubricated by a high capacity filter/regulator/lubricator
assembly. Requires 75 CFM at 80 psig. Intended for
four respirator users or three hood users.

AMBIENT AIR PUMPS
A-300
Ideal for a super portable, lightweight air source
for a single respirator user. Solid performance in
applications of one-worker painting, cleaning,
sanding or chemical handling operations.
9806
A-750
Fills the need for a very portable air source for
one or two respirator users or a single hood user.
Works well in a variety of work environments
including painting or refinishing booths.

WARNING: Ambient Air Pumps are not to be used with generators.
WARNING: Air inlet to the pump must be located where breathable air can be assured at all times.
WARNING: Ambient air breathing pumps should be used only in areas containing sufficient oxygen to support life. Do not use where contaminants are Immediately Dangerous to Life and Health (IDLH).
CAUTION: NIOSH approved respirators and corresponding hose lengths must function at pressures generated by air pumps. Only class “C” (constant flow) respirators will work properly.
NOTE: Pumps contaminated with toxic or hazardous materials cannot be returned under guarantee.
LP ALLEGROAIR AIRLINE COOLING SYSTEM
Perfect, low cost, portable means of cooling breathing air
while keeping workers comfortable and productive. The system
is capable of reducing air temperature from 180°F to 50°F.
The cooling system is connected to the Ambient Air Pump
through a 5' long inlet supply airline. Air flowing through the
FDA Grade PVC coil inside the 70 quart cooler reduces the air
temperature by having ice poured on and around the coil.
The outlet air is filtered by a 5 micron particulate air filter.
An adjustable relief
valve allows the user
to adjust the air flow.
Can be used with up
to 3 workers. Comes
with durable wheels
and a locking tele-
scoping pull handle.
Dimensions: 20"w x
21"d x 24"h, 28 lbs.

FLOW TEST KIT FOR CONSTANT FLOW
SUPPLIED AIR RESPIRATORS
CFM tester checks the volume
of air that gets to the respirator.
A flow meter simply quick
connects onto an airline hose
to check the respirator system
for NIOSH compliant air flows.
The kit contains flow meter
and a full assortment of quick
connect plugs and adapters to fit
all respirator manufacturer’s airline hoses. Excellent for use
with ambient air pumps. NOTE: NIOSH mandates 4 CFM for
tight-fitting masks and 6 CFM for hoods.

INLET HOSE
EXTENSION KIT
Respirators must be supplied
with a source of clean,
breathable air at all times as
per OSHA 29CFR 1910.134.
In order to achieve this requirement, at times
it may be necessary to use an inlet hose extension from the
ambient air pump to a clean air environment. This can be
achieved by connecting one of our inlet hose extension kits,
allowing the inlet air source to be 50 feet away from the
pump. Or connect up to 5 total kits together for a total of
250 feet away from the pump. Included in the kit is (1) 1”x 50’
heavy duty hose and various fittings to ensure the hose fits to
whatever Allegro Ambient Air Pump you have.

AMBIENT AIR PUMP CO MONITOR
The Ambient Air Pump CO Monitor alerts workers using
supplied air respirators when the level
of carbon monoxide has exceeded
10 ppm (5 ppm Canada). The CO
monitor can be operated in AC or
DC mode and uses a single 9-volt
alkaline battery. Housed in a
portable, rugged Pelican
case with handle and
latches for protection
and security. Comes
with a threaded Tee.
Dimensions are 8¼”l x 3½”w x 6¾”h. Weighs 3½ lbs.
