When the air pressure becomes greater than that of the preset “cut-out”, the governor controls the unloader mechanism of the compressor to stop the compressor from building air and also causes the air dryer to purge.
When does an air dryer need to be replaced?
Drivers and fleets should always monitor the quality of the air in their service tanks to ensure air dryers are functioning properly. If excessive moisture—or oil mixed with water—is present in an air system, the air dryer’s cartridge may need to be replaced.
How to tell if air dryer is bad or needs the filter?
If you drain your air tanks out and are consistently seeing a lot of water, I’d start with changing out the cartridge on the drier. Water in the airlines won’t hurt anything in warm weather immediately but it isn’t great to have it inside your tanks and aluminum valves. The water will freeze up in winter though.
