Description Designed to reduce pollutants in respirator air supplied to air fed helmets. The filter will remove mists, including oil mist, water vapour and particle down to 0.5 micron from a suitable compressed air supply that is free from carbon monoxide in accordance with BS: 4275:1997. PLEASE NOTE: The cartridge WILL NOT remove carbon dioxide, carbon monoxide or other toxic gases. We recommend cartridges are changed every 3 months (as a minimum) or more frequent if oily odours or particles are present in the helmet.
