Dräger PAS® ASV

The Dräger Automatic Switch over Valve (PAS® ASV) enables the user to connect compressed air breathing apparatus to an external air supply, such as a factory ring main, and be safe in the knowledge that if the external supply were to fail, there would be a safe and uninterrupted transition to the wearer’s back-up air supply.

Warning device

A warning device warns that the wearer is now breathing from cylinder compressed air.

Low profile and light

Due to its compact design the PAS ASV can be used easily in confined spaces.

Uninterrupted airsupply

If the external air supply fails, then the unit will automatically switch to the compressed air breathing apparatus for its supply of air. During the switch over operation the ASV maintains positive pressure within the facemask at all times.
