Product Overview

The air dryer cartridge, OEM number 23690622, is the desiccant filter cartridge fitted to the air brake dryer system across a wide range of heavy truck brands, including Volvo, DAF, MAN, Renault Trucks, and Mercedes-Benz commercial vehicles. Since this cartridge is cross-referenced across so many truck manufacturers, it's a genuinely high-turnover part for anyone supplying heavy truck and commercial fleet parts.

Worn or saturated units typically show up as moisture or oil in the air brake system, longer air compressor run times, or the air dryer purging more frequently than normal. GSK Auto manufactures this cartridge to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

(Confirm against your chassis code or air dryer model before ordering - this cartridge is cross-referenced across multiple truck brands and air dryer housing designs, so it's worth double-checking the exact air dryer model before ordering at volume.)

What Is an Air Dryer Cartridge?

Function: The air dryer cartridge removes moisture, oil, and contaminants from compressed air before it enters the truck's air brake system, protecting brake valves, chambers, and lines from corrosion and freezing.

Working Principle: Compressed air from the compressor passes through the desiccant material inside the cartridge, which absorbs moisture and traps contaminants, with the dryer periodically purging accumulated moisture during the regeneration cycle.

Importance: On air-braked heavy trucks, moisture in the brake system can cause valve freezing in cold weather, corrosion inside brake components, and reduced braking reliability, making the air dryer cartridge a safety-relevant maintenance item.

Common Failures & Signs: Desiccant saturation reducing the cartridge's ability to remove moisture effectively. Moisture or oil found in the air brake system during inspection. Longer air compressor run times as the system struggles to build and maintain pressure. More frequent air dryer purge cycles than normal.
