consists of an SR 90 half mask, which is supplied with compressed air through a hose from a regulating valve on the user's belt.
A standard filter of suitable type in the mask provides protection against the loss of compressed air supply and protects the user while he is walking to and from the workplace.
Can also be used without filter backup, such as under a visor. As a result, the SR 90 Airline has a very wide field of application.
The air flow rate can be controlled by means of a regulating valve on the user's belt to a value between approx. 150 and 320 l/min. The supply pressure to the regulating valve should be between 4 and 6 bar. A flow meter and a warning whistle for temporary and continuous monitoring of the air flow are included.
Tested in accordance with EN 14594:2005.
