The Bendix AD-IP® Air Dryer keeps you Ready for the Road Ahead™, systematically filtering moisture from the compressed air through a desiccant element before it reaches your supply (wet) tank. This heavy duty air cartridge is important for the exact intake and operation of your truck’s air brakes. Heavy duty trucks require compressed air to actuate braking systems and monitor the brake operation. Symptoms of a bad air dryer in need of replacement are leaking air, blocked purge valves, or poor performing condensers unable to receive built pressure. This heavy duty air dryer ensures your braking system is in pristine condition with clean, dry air. FleetPride is your First Click in Heavy Duty®.
