The heart of the Haldex DRYest and PURest air dryers is the interchangeable Multi-Treatment Cartridge. With a five-stage cleaning system, the Multi-Treatment Cartridge delivers up to three times the water-drying capacity of other air dryers.

This water drying capacity doesn't impede airflow, so corrosion and freezing problems are minimized. Designed to remove up to 99% of contaminants in the compressed-air system, it eliminates oil while maintaining its adsorption capability.

The five-stage cleaning system begins by eliminating solid particles through a fine corrosion- and chemical-resistant aluminum mesh. Air then flows through a large desiccant bed where oil and water droplets are eliminated. A second desiccant bed removes oil and water vapor, while the main desiccant bed treats water vapor and any remaining contaminants. As a final precaution, ultra-fine particulates are removed from the airflow through a dust filter before the air enters the system.

Extended desiccant service life of the Multi-Treatment Cartridge means fewer replacements over the life of a vehicle. Its four-bolt slide in-and-out design allows for quick replacement while still on the vehicle — with no hard-to-remove spin-on cartridges with seized threads. Its 11" height requires only a 1/2" vertical clearance.
