Compressed air additive SUNDSTRÖM
SR 307

Compressed air additive for compressed air feeding of Sundström full or half masks. The combination is 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 materials that do not cause sparks during friction, which enables 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. The compressed air should be cleaned with a compressed air filter type Sundströms SR 99-1.
