Sundstrøm SR 90 Airline Half Mask for Compressed Air S/M

Half mask SR 90 in silicone with medium hose and belt with control valve for compressed air supply. The mask has a good fit and high comfort. Overpressure in the mask prevents accidental leakage. The belt is equipped with a warning whistle if the pressure drops. The mask has the possibility of a combination with a passive filter, so the user is protected during pressure drops, and outside the workplace. Using a passive filter is an option and not a requirement. The air flow to the mask is controlled via the control valve in the belt. Min./max. 150/320 l/min. A flow meter is included separately. The working pressure on the entrance side of the belt should be 4-7 bar. The compressor air must be cleaned by a filter panel, for example SR 99.
