Sundstrøm SR 90 Half Mask for Airline M/L

Half face mask SR 90 in hypoallergenic silicone with interconnect hose and belt with control valve for compressed-air supply. The mask has good fit and high comfort. Excess pressure in the mask prevents accidental leakage. The strap is fitted with a warning whistle if the pressure drops. The mask can be combined with a passive filter to protect the user in the event of a pressure drop and on the way to and from the work site. Using a passive filter is an option and not a requirement. The airflow to the mask is controlled via the control valve in the belt. Min/max 150/320 l/min. A flow meter is supplied separately. The working pressure on the inlet side of the belt must be 4-7 bar. The compressor air should be cleaned by a filter panel, e.g. SR 99.
