Volvo 21620181 Air Dryer Cartridge

Description

The Volvo 21620181 cartridge works as an air dryer cartridge for Volvo trucks, designed to remove moisture and contaminants from compressed air systems. It helps protect brake equipment, cab systems, and auxiliary components from corrosion and freezing. By keeping air dry and clean, this cartridge supports safe and reliable truck operation.

Volvo designed the 21620181 cartridge to meet OEM standards, and it matches several cross-reference parts: Meritor TDAS432-420-220, TDAS432-420-220-2, WAB432-420-923, WAB432-420-923-2. In addition, it replaces Volvo part numbers 20972915 and 20557234 in many systems. The robust housing withstands wide temperature changes and frequent cycling.

The Volvo 21620181 cartridge maintains consistent airflow under heavy-duty conditions. Therefore, drivers operating in cold, wet climates benefit from fewer freeze-ups and less maintenance. It resists clogging even with moisture in intake air and works reliably with standard desiccant media. Furthermore, the construction ensures tight sealing and long service intervals.

For better performance, pair this part with a matched pre-filter or check sealing O-rings when servicing. You can also explore our Volvo filters collection to get the right air dryer cartridges and related parts.
