SR 90 Airline S/M

SR 90 Airline is a compressed air mask with filter back-up, designed for connection to an appropriate compressedair supply with breathable air. The overpressure which builds up in the mask prevents contaminated ambientair from reaching the user. SR 90 Airline can be used as an alternative to filter protection in all situations wheresuch protection is recommended. This applies particularly to heavy work or long-duration work, and wherecontaminants do not provide adequate warning, or are especially toxic.The mask is made from a material that does not cause sparks in the event of friction, which allows it to be usedin explosive or inflammable environments.The control valve is fitted with a warning whistle which operates if the air quantity falls below the recommendedvalue. A flow meter for monitoring air flow is included. Compressed air should be purified with a SundströmsSR 99 compressed air filter. See separate production information.
