Airline filters can be used in conjunction with other compressor safeguards to supply cleaner air to supplied air-respirators. Air filters reduce pollutants in respirator air supplied to workers. These filters remove mists, water vapors and particulates from air supplied by compressor.
Air enters the filter through side inlet port. Moisture is removed by expansion in the filters outer chamber and passes out through a drain cock at the bottom of the unit. The air is then forced through a filter cartridge which contains several filtering materials including activated charcoat before it passes out through the top of the filter and into the hose to the helmet.
