Compressed air mask SUNDSTRÖM
SR 90 Airline

Compressed air-fed half mask with filter back-up and excellent fit, high protective effect and very good breathing comfort for the toughest areas of use. Intended to be connected to a suitable compressed air source with breathable air. The overpressure that then occurs in the mask prevents the surrounding polluted air from reaching the user. Can be used as an alternative to filter protection in all situations where such is recommended. This applies in particular to heavy or long-term work and when the contaminants have poor warning properties or are particularly toxic. Made of non-sparking friction material, enabling use in explosive/flammable environments. The control valve is equipped with a warning whistle that gives a signal if the amount of air falls below the recommended amount. Flow meter for checking the air flow is included. The compressed air should be cleaned with a compressed air filter type Sundströms SR 99-1.
