DU-4 AIR DRYER
The air dryer sits at the front of the brake air circuit, and its job is to keep water and oil out of the system. Our units are designed to handle that task efficiently, with a straightforward housing layout and service points that match standard workshop tools. Desiccant cartridges are easy to replace, purge cycles are calibrated for typical duty patterns, and the exterior finish is selected to withstand routine cleaning and weather exposure. Compatible with many commercial vehicle platforms, it’s a practical choice for fleets that prefer predictable servicing and steady operation over time.
