Sundstrøm SR 90 Airline Half Mask, M/L

SR 90 Airline consists of an SR 90 half mask, size M/L, where the pressurized air is supplied to the mask body via a hose from the regulator valve in the belt. With a suitable filter combination in the mask, it provides protection in the event of pressure loss and when moving to and from the workplace.

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