Description
World American WA1314711010 is a complete System Saver SS1200 Plus 12V air dryer assembly with integrated governor, purge tank, and turbo cut-off valve. It replaces Wabco 4324711010 and Freightliner F224870 with matching ports, voltage, and pressure settings. The oil-coalescing cartridge strips moisture, oil aerosol, and contaminants out of compressor discharge before the air reaches the brake circuit.
Signs You Need a New Air Dryer
- Excessive moisture or oil in the wet tank when drained
- Constant purge cycling, or no purge at all
- Slow air pressure build-up after start
- Brake valves freezing or sticking in cold weather
- Corrosion appearing on downstream brake components
