GENERAL INFORMATION
The Ambient Air Pump is designed to intake fresh, clean air from a non-contaminated atmosphere and supply this fresh air to a
continuous flow supplied air respirator.
The clean air is filtered through a porous plastic intake muffler designed to protect the pump from dust and dirt particles. The outlet air
supplied to the respirator is filtered through an activated charcoal filter designed to remove tastes and odors from the breathing air.
MST’s Ambient Air Pump is oil-less and has rotary carbon vanes. The pump does not produce carbon monoxide, oil vapors, oil mist
or moisture, however it is extremely important that the atmosphere from which the air is drawn into the pump is clean and free of any
carbon monoxide or other toxic gases or vapors. In Canada, the Canadian Standards Association defines breathing air requirements
under CSA Z180.1; refer to “Breathing Air Requirements” within this manual. This standard includes direction regarding the
installation, commissioning, and maintenance of ambient air pump systems.
The Ambient Air Pump will supply a maximum air flow rate of ten (10) SCFM of breathing air to one worker or a maximum supply
pressure of fifteen (15) psig. USE ONLY MSHA/NIOSH APPROVED RESPIRATORS THAT WILL OPERATE AT
PRESSURES LESS THAN FIFTEEN (15) PSIG.
