Dräger PAS® ASV
A warning device warns that the wearer is now breathing from cylinder compressed air.
Due to its compact design the PAS ASV can be used easily in confined spaces.
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.
