Prepare your truck to be Ready for the Road Ahead® with the Bendix Remanufactured AD-IS® Air Dryer that efficiently removes moisture from compressed air to ensure optimal brake performance. Through the use of an internal desiccant, this filtration system prevents moisture and liquids from entering your supply and wet tanks by collecting contaminants. Each device is constructed with heavy-gauge metal to ensure integrity, as well as an included governor. Air dryers in need of replacement often show symptoms such as leaking air, blocked purge valves, or poor-performing condensers that can't receive built pressure. FleetPride is your First Click in Heavy Duty®.
