The QUEST range of SCBA Respirators are best suited for Type 1 (Industrial) use in various conditions. The QUEST ASV for industrial use is equipped with an Automatic Switch Valve (ASV) that switches from the airline/cascade hose supply to the SCBA breathing air cylinder supply in the event of an interruption or failure of the hose supply.
When the automatic switch over occurs, an automatic audible alarm (whistle) sounds to alert the wearer they are now being supplied by breathing quality air from the SCBA cylinder.
