How does the purge cycle on an air dryer work?
The purge cycle of the air dryer begins when the governor causes the compressor to unload (stop compressing air). During compressor unload, the line connecting the governor unloader port to the AD-9 air dryer end cover control port is pressurized. The air pressure causes the air dryer purge valve to open.
How often does my dryer Purg every 30 seconds?
The dryer is purging about every 30-45 seconds. It does this whether I am parked or driving. I know I do not have any air leaks as I only lose about 5 PSI over 24 hours. -The pressure in the tanks seem to stay steady at about 120psi.
How often does a Bendix air dryer Purg?
Air dryer purges too often, perhaps as frequently as every 15 seconds, accompanied by excessive cycling of the compressor. Likewise, how do you adjust a Bendix air dryer?
The purge cycle of the air dryer begins when the governor causes the compressor to unload (stop compressing air). During compressor unload, the line connecting the governor unloader port to the AD-9 air dryer end cover control port is pressurized. The air pressure causes the air dryer purge valve to open.
How does an air purging system work in a car?
How this system works is there is an air pressure signal line that comes from an air tank to the governor. When there is 120 psi (give or take a few) of air at the governor it is signaled to supply the unloader in the compressor and to purge the drier. Once this happens the compressor is no longer compressing and the drier has purged.
Why does my air compressor keep purging air?
