The wabco air dryer is a popular, compact dryer found on many over-the-road trucks. It features a spin-on desiccant cartridge.

Wabco air dryers protect air systems in heavy-duty vehicles that require clean air to properly operate. Not only does the wabco air dryer work to remove contaminants like water and vapor before they reach the air brake system, but the truck part helps reduce the chance of premature failure in other systems. 

Wabco air dryers may fail due to leaks, clogs or worn electrical issues. It is important to replace the wabco air dryer cartridge during routine maintenance on air brake systems.
