Ordering a Haldex “Pure Air” air dryer

Pure Air air dryers are an older dryer model that is still found on the road today. They can be mounted horizontally or vertically, and they are serviceable from either end.

Ordering a Pure Air air dryer

We sell all Pure Air dryers as non-returnable special orders. 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 N4244 or N4244A.
