Midland/Haldex PURest Air Dryers

The Haldex PURest air dryer's large purge volume eliminates the need for an external purge tank, and the multi-treatment desiccant cartridge removes up to 99% of contaminants from the air system. This air dryer includes a universal mounting bracket that will allow easy retrofitting of Pure Air Plus dryers as well as most Bendix AD series and WABCO System Saver dryers.

Ordering a PURest air dryer

We'll need a part number from your existing air dryer or the vehicle manufacturer's part number in order to determine the current Haldex aftermarket part number. The part number on your existing air dryer will usually start with a 'N' followed by numbers and maybe another letter, such as N4253AA.
