general information
Bullard Free-Air Pumps transfer ambient air from a clean air location, where
breath-able air can be assured at all times, to workers wearing Type C or CE con-
tinuous flow supplied-air respirator hoods or tight fitting half or full face masks.
The ambient air is filtered through a medium efficiency Inlet Air Filter and a
Carbofine Outlet Filter before entering the respirator'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 expen-
sive carbon monoxide monitors, high temperature alarms or airline filters. No
calibration is required.
note
Drive-Air pressure (psig) determines horsepower of air motor which
directly affects output air pressure and output air volume. When operating
a hood-style respirator with a Frigitron 2000 Series air conditioner incoming
drive air pressure must be set at 95 psig for optimum pump performance.
Attempting to operate a hood-style respirator with a Frigitron air
conditioner with the incoming drive air at less than 95 psig may result in an
inadequate supply of air to the worker. See below for pump performance.

  • Page 2 ** It should be noted that the minimum air flow required for each tight-fitting, mask-style respirator is four (4) cfm. A minimum airflow of six (6) cfm is required for each hood-style respirator. The ratings which appear here, therefore, are conservative, but reflect Bullard Company’s position that worker respiratory protection is enhanced when air flow available to the respirator wearer is above the NIOSH required minimums.
