Compressed airline half mask with filter back-up and excellent fit, high protection factor and breathing comfort for the toughest work environments.
SR 90 Airline is a compressed air mask with filter back-up, designed for connection to an appropriate compressed
air supply with breathable air. The overpressure which builds up in the mask prevents contaminated ambient
air from reaching the user. SR 90 Airline can be used as an alternative to filter protection in all situations where
such protection is recommended. This applies particularly to heavy work or long-duration work, and where
contaminants 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 used
in explosive or inflammable environments.
The control valve is fitted with a warning whistle which operates if the air quantity falls below the recommended
value. A flow meter for monitoring air flow is included. Compressed air should be purified with a Sundströms
SR 99 compressed air filter. See separate production information.
