Get Ready for the Road Ahead® with clean and dry compressed air that enhances brake performance, thanks to the WABCO SS1200P Air Dryer. This air dryer effectively removes moisture from compressed air through an internal desiccant to prevent system damage and ensure optimal performance. This model is compatible as a replacement for several brands such as Freightliner, Kenworth, Mack, Meritor, Navistar, Peterbilt, and Volvo. To confirm your air dryer needs replacing, check for signs 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®.
