General Information

Bullard Free-Air Pumps MUST be located in a clean air envi-
ronment where at least Grade D breathable air is assured at
all times. Bullard Free-Air Pumps transfer ambient air from a
clean air location, where at least Grade D breathable air can be
assured at all times, to workers wearing Type C or CE continu-
ous flow supplied-air respirator hoods or tight fitting half or full
face masks. Only NIOSH approved respirators should be used
with this pump.
The ambient air is filtered through a medium efficiency Inlet Air
Filter and a Carbofine Outlet Filter before entering the respira-
tor's air supply hose.
Bullard Free-Air Pumps are oil-less and have rotary carbon
vanes. They produce no carbon monoxide, oil vapors, oil mist
or moisture. They do not require expensive carbon monoxide
monitors, high temperature alarms or other standard supplied
air pressure monitoring equipment. No calibration is required.

NOTE
Industrial High Pressure Compressed Air (psig) determines
horsepower of air motor which directly affects output
air pressure and output air volume that comes from the
Free Air Pump Compressor that is sent to the Respirator
System.
