AMD with Adjustable Regulator All Stainless Steel 316 Construction Model AMD-75
The BERMAD AMD-75 (Air Maintenance Device) is a pressure control unit that automatically regulates the supplied air pressure to a constant preset value. It is suited for use with dry pilot actuated Deluge systems as well as Dry Pipe and Pre-action systems.
The AMD includes a field-adjustable pressure regulator, through which the air/nitrogen supply can be reduced to a constant and stable pressure, a check valve to maintain system pressure in the event of pressure source failure, a filter to ensure a clean air supply, and a bypass valve for a quick initial air pressure filling of the system.
