Air compressor to get back into the hot air dryer before the wet rain valve, a rear air-cooled chiller cooling the exhaust air from the compressor to 100? F (38 ℃). With a differential pressure gauge condensation pre-filter can remove oil mist and other impurities can damage the drying tower desiccant. Adjusting the air pressure to the sprinkler system at the same time through a synthetic particle filter and automatic regulator valve good quality wet rain to prevent leakage of desiccant dust down. For ease of installation and electric devices in place mechanism, all parts should be pre-set control, testing and connection. AMD-1 under reduced pressure maintenance device type AMD-2 type air compressor control pressure maintenance device AMD-1 type pressure-pneumatic pressure regulator to maintain the best wet with rain field adjustable valve means for pre- the role of the system, the pressure dry systems or deluge system, preaction system dry pipe network control start. AMD-1 using compressed air in place, such as an air compressor with a pressure tank, factory air, nitrogen bottle, air pressure with a pressure regulator must be higher than the pressure in the pipe system requirements. AMD-1 is used in place of the central company D-2, GEM companies F324 and S460 STAR company pressure maintenance device.
