• Designed for use with nitrogen generators and air compressors Assembled in USA using corrosion-resistant components No power required for operation Provided with a corrosion-resistant mesh screen (50 or 60 mesh) to prevent the entry of particles into the regulator and sprinkler system Manual bypass to allow quick filling of sprinkler systems after operation or maintenance

The advanced air maintenance device (Advanced AMD) is a field adjustable pressure regulating device used to keep nitrogen or air pressure at the correct level in dry pipe and preaction fire sprinkler systems. It can also be used to control pressure in dry pilot line systems of dry pilot actuated deluge or preaction valves. The advanced AMD is used in sprinkler systems with an automatically controlled compressed nitrogen or air source that is at a pressure higher than required for proper system operation. These sources can include nitrogen generators and air compressors dedicated to the fire sprinkler system and plant air or nitrogen systems. The advanced AMD includes a manual bypass that, after sprinkler system maintenance or operation, allows quick filling of the sprinkler system.
