Cartridge filter / breathing air / compressed air / polypropylene

Airblast Helmet Air Filter (HAF) is designed to remove oil mist, water vapour and particulates down to 0.5 micron
from breathing grade compressed air. The Airblast Helmet Air Filter meets OSHA regulation 1910.94 (6) (ii),
requiring a trap and carbon filter be installed and regularly maintained to remove objectionable odours, as well as
water, oil mist and other particulates.
The Airblast HAF is supplied incl. pressure reducing valve to reduce the pressure to the requirements of supplied air
respirators, providing that the inlet pressure does not exceed 8,6 bar (125 PSI).
Operation
The HAF is placed in the breathing-air line between the breathing air source and the respirator supply hose. The
HAF is the point of attachment for the respirator hose. Air enters the filter through one of the inlet ports. Moisture
is removed by expansion in the outer chamber and is drained through a petcock at the bottom of the unit. The air
passes through a replaceable filter cartridge. The outlet pressure is controlled by a regulator on the cap and is
measured by a gauge downstream from the cartridge.
Advantages
? One filter suitable for multiple respirators, up to 6 users
? Polypropylene filter cartridge casing eliminates corrosion hazard
? Filter cartridge lasts up to 3 months (based on 40 hours week)
? Filters can be floor or wall mounted
