Prepare your truck to be Ready for the Road Ahead® with the WABCO SS1200 Plus Air Dryer that efficiently removes moisture from compressed air to ensure optimal brake performance. To prevent contaminants from entering your wet and supply tanks, this device utilizes a filtering desiccant element that removes moisture from the compressed air. This helps your vehicle actuate its brakes more efficiently, while also reducing long-term wear and tear. To confirm your air dryer needs replacement, check for symptoms such as leaking air, blocked purge valves, or poor-performing condensers that are unable to receive built pressure. FleetPride is your First Click in Heavy Duty®.
