Bullard ADP20 Free Ambient Air Driven Pump Respirator Supply System

Bullard ADP20 is an intrinsically safe free air pump for 6 half face or 4 hood style respirators.

When utilized in clean air environments, Bullard Free Air pumps give you a low cost means to supply breathable clean air to multiple respirator wearers who are working in a contaminated environment up to 300 ft. away from the ambient air pump. These pumps are oil less, so they don't output carbon monoxide, oil mist or vapor. This makes is perfect for hazardous duty or general purpose use.

The ADP20 is the perfect for personnel working in a location without a source of electrical power (but has available compressed air). It is also ideal to use in potentially explosive environments which require an expensive, explosion proof electrical motor.

Costly carbon monoxide (CO) alarms might not be needed as drive compressor air isn't transferred to workers. The pump requires a fresh, clean ambient air source that is filtered to block certain particulates & then transferred to workers. Compressed air with a minimum air volume of 85 CFM at 95 PSIG (2407 LPM at 655 kPa) is only used as the energy source.

Bullard's powerful ADP20 is versatile and allows a personal Bullard air conditioner to supply enhanced worker comfort & productivity. The pump delivers 30CFM of air at 5 PSIG (850 LPM at 34.5 kPa). The maximum output pressure is 25 PSIG (172.4 kPa).

For greater comfort, the ADP20 may supply air for 1 worker with Bullard's Frigitron 2000 (air conditioner) in conjunction with the CC20 or 88-Series hood style respirator. The Frigitron lowers the air supply temperature to the respirator's hood by 20 degrees F (11degrees C) maximum, resulting in comfortable & productive workers.
