Helmet Airfilter 1-2 AIRBLAST HAF
Common Characteristics
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.
