The pressure reducer is designed to be connected to 200 or 300 bar compressed air cylinders.
The warning signal at the pressure reducer is high pressure controlled and *****medium pressure dosed*****. Thus a loud, constant signal sounds during the total alarm. The great advantage of this is that the warning device functions injector-less: i.e. the input of ambient air is not required to discharge the warning signal.

Also on the pressure reducer is the pressure gauge line with a large luminescent and pivotable pressure gauge, as well as the medium pressure line to connect the lung governed demand valve.

The compressed air cylinder is fastened onto the carrying plate with a cylinder retaining strap. The strap's universal length permits the use of cylinders of various sizes. A large, handy tightener, fitted with a locking device permits the swift and easy exchange of cylinders.
