breathing air Requirements
air Quality
The Free-Air pump’s inlet air filter MUST be located in a place where there is clean,
breathable air at all times.
The breathable air drawn into the inlet filter must meet at least the requirements
for Type 1 gaseous air described in the Compressed Gas Association Commodity
Specifications G-7.1 (Grade D or higher), as specified by Federal Law 30 CFR, Part 11,
Subpart J, 11.121 (b).
The requirements of Grade D breathable air include:
- Oxygen ............................................................................. 19.5 - 23.5%
- Hydrocarbons (condensed) in mg/m
3
of gas ................ 5 mg/m
3
maximum
- Carbon Monoxide ............................................................ 10 ppm maximum
- Carbon Dioxide ................................................................ 1,000 ppm maximum
- Odor ................................................................................. No detectable odor
- No toxic contaminants at levels which would make the air unsafe to breathe.
Refer to the C.G.A. Commodity Specification G-7.1 for complete details. It is available from:
Compressed Gas Association
500 Fifth Avenue
New York, NY 10036
assembly and installation
For the specific location of the pump components referred to below, see the list of
pump components to the left.
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 located 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 instructions.
If clean breathable air cannot be guaranteed 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 (13), passes through PRESSURE
REGULATOR (12); where pressure is controlled.
Air pressure is adjusted with REGULATOR kNOB (14) and is read on GAUGE (4)
(NOTE: 80 psig or higher during operation is normal for this motor).
2. Air is exhausted through MOTOR ExHAUST MUFFLER (15) 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 in the section above).
The pump draws in air using four sliding carbon vanes set in a rotor, and discharges it
under low pressure out of discharge port.
