DRYest® Air Dryer

The Haldex DRYest is designed to provide your air brake system with clean air utilizing low initial system costs and ensuring extended system life. This is accomplished by providing more integrated features than any other air dryer on the market. DRYest is available with integrated: turbo protection valve, governor, regeneration valve, muffler and heater. DRYest adapts to fit YOUR application.

Typically this air dryer is used in a system where the secondary tank works in conjunction with the regeneration valve to purge the dryer. However, DRYest can be used with auxiliary purge tanks or can even be used with European unloader systems where the compressor unloads through the dryer.
