Free-Air® Pumps 

User Manual

General Information

Bullard Free-Air Pumps transfer ambient air from a clean air location, 
where breathable air can be assured at all times, to workers wearing 
Type C or CE continuous flow supplied air respirator hoods or tight 
fitting half- or full-face masks.

The ambient air is filtered through a medium efficiency inlet 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 expensive carbon monoxide monitors, high 
temperature alarms or airline filters. No calibration is required.
Read all instructions before using your Free-Air pump.
