Bullard Free-Air® Air-Driven Pumps
When placed in a clean air environment, Bullard Free-Air® pumps offer a low-cost means of supplying clean, breathable air to respirator wearers working in contaminated environments up to 300 feet away from the pump. Bullard Free-Air Pumps are oil-less, so they do not produce carbon monoxide, oil vapor or oil mist. The air driven model is ideal for both general purpose and hazardous duty use.
The air driven Free-Air Pump supplies air to four hood-style or six half or full face mask respirators approved to operate at 25 psig or less. Intrinsically safe and offering an inlet drive pressure of 95 psig, air flow is 30 cfm at 5 psig. The ADP20 is also compatible with the Bullard Frigitron 2000 climate control devices (for one worker).
ADP20
- Air Flow: 30 cfm at 5 psig. Supplies air to:
