Ensure you're Ready for the Road Ahead® with the WABCO SS1200P Air Dryer, an air dyer designed to keep compressed air clean and dry for optimal brake performance. This replacement part effectively removes liquids and water vapors from compressed air to prevent contaminants from entering your wet and supply tanks. Once installed, it can greatly extend the lifetime of a brake system by reducing exposure to harmful contaminants. An air dryer in need of replacement shows symptoms such as leaking air, blocked purge valves, or poor-performing condensers that can't receive stored pressure.
