The first stage regulator lowers the high pressure (max. 400 bar) to a constant pressure of 7 bar. It is placed inside the shell housing and therefore perfectly protected from shocks. A snap-on guide and a joint make it easy to connect to the cylinder valve and to see that it is correctly positioned. Its maximum flow rate allows the supply of 2 SCBA wearers or one wearer and a rescue bonnet. Its maintenance is facilitated by a recyclable cartridge system.
The regulator is available in 2 versions : snap-on release on the mask or release on the first breath.
