Air Dryer & Cartridges

Semi truck air dryers & cartridges are supplied by the most reliable brand TTP has to offer. Choose from TTP, Bendix, Freightliner, & Alliance. Changing your air dryer cartridge depends on how you drive the truck. Most truck drivers recommend you change these every two or three years. The more frequent replacement might be required if the truck compressor passes a lot of oil.

"Oil passed by the compressor is the enemy of the air dryer. Mixed with water, oil plugs up valves. But it also coats the desiccant inside the dryer cartridge until, eventually, the cartridge can no longer remove moisture – which leads to excessive moisture in the service tanks." - Bendix
