Air Dryer Cartridges

The genuine WABCO Air Processing Unit and Air Dryer cartridges engineered to keep air brake systems operating at optimum levels of performance, helping to ensure vehicles stay on the road and out of the maintenance bay


What do these Air Dryer Cartridges do?

WABCO was the first to introduce to the automotive market an air dryer cartridge with an integrated coalescing function that separates humidity and fine oil aerosols to protect the air system.
