Sundstrøm SR 90 Airline Half Mask

SR 90 Airline consists of an SR 90 half mask, size M/L, with pressurized air delivered into the mask body through a hose from the regulator valve on the belt. With a suitable filter combination in the mask, protection is provided in the event of pressure loss and during transfer to and from the workplace.

• It can also be used without filter backup, for example under a face shield. This provides a very wide range of applications for the SR 90 Airline. The airflow is controlled by the regulator valve on the belt to a flow in the range 150-320 l/min. The supply pressure at the regulator valve should be 4-7 bar.
• A flow meter and warning whistle for occasional and continuous monitoring of the airflow are included.
