Midland/Haldex Pure Air Plus Air Dryers

Pure Air Plus air dryers are usually found on coach chassis from the 1990s. Haldex is no longer producing new Pure Air Plus dryers, but remanufactured units are still available.

Ordering a Pure Air Plus 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 N4250 or N4250C.
