Product Details: Get Ready for the Road Ahead® with clean and dry compressed air that enhances brake performance, thanks to the Bendix AD-IS® Oil Coalescing Air Dryer. Through the use of an internal desiccant, this filtration system prevents moisture and liquids from entering your supply and wet tanks by collecting contaminants. The oil coalescing cartridge then works to remove dirt, oils, and aerosols so they don't make their way into your air supply. As a result, the contaminants are easily trapped to prevent unnecessary wear and tear to a brake system. Air dryers in need of replacement often show signs such a leaking air, blocked purge valves, or poor-performing condensers that can't built pressure. FleetPride is your First Click in Heavy Duty®.
