Air Dryer Filter 21620181 / BA5379 / AD27747 for Volvo, DAF, Iveco, MAN & Mercedes-Benz Trucks

Description

This 21620181 air dryer filter is a coalescer-style spin-on air dryer cartridge engineered as a direct replacement for the Volvo 21620181 and Fleetguard AD27747, used across a wide range of European and North American heavy-duty trucks, including Volvo (D13/D16J/D13J engines), DAF, Iveco, MAN, and select Mercedes-Benz models. It’s a component of the truck’s air brake system, designed to remove moisture, oil, and contaminants from compressed air before it circulates through the brake circuit.

Product Overview

The 21620181 air dryer filter uses coalescing filter media designed to separate moisture and oil vapor from compressed air in the truck’s air brake system, helping protect downstream valves and brake components from corrosion and contamination. As explained in this overview of how truck air dryers work, removing moisture from compressed air before it reaches the brake system’s tanks and valves is essential for preventing rust, freezing, and premature component failure. As a spin-on cartridge, it threads directly onto the air dryer assembly for straightforward replacement during scheduled maintenance. Each unit is dimensionally verified against OEM measurements before shipment — not just matched by part number.

Fits the Following Truck Brands, Engines & Models

This is a widely cross-referenced air dryer cartridge used across multiple truck brands sharing a common air dryer housing design. Always confirm your specific truck’s serial number range and air dryer assembly against the OEM cross-reference before ordering, especially for bulk purchases across multiple brands.

OEM Cross-Reference Numbers

Note: this filter is closely related to the Baldwin BA5374 (a desiccant version of a similar air dryer cartridge). Confirm you need the coalescer version (BA5379/21620181) rather than the desiccant version before ordering, as the two serve different functions within the air dryer system.

Frequently Asked Questions

What does an air dryer filter do? It removes moisture, oil vapor, and other contaminants from compressed air before it enters the truck’s air brake circuit, helping prevent corrosion and contamination in downstream valves and brake components.

Is the 21620181 the same as the BA5379 and AD27747? Yes. The Volvo 21620181, Baldwin BA5379, and Fleetguard AD27747 are all cross-referenced to the same coalescer air dryer cartridge specification, along with the Donaldson P951413 and WIX SS10129/WS10129 equivalents.

Does this filter also fit DAF and Iveco trucks? Yes. This is a widely used air dryer cartridge shared across multiple truck brands, including confirmed applications on DAF (65/75/85 CF series, 95XF), Iveco (EuroCargo, EuroTech, EuroTrakker, Stralis), MAN (TGA/TGM/TGS/TGX), and select Mercedes-Benz models, in addition to Volvo. Always confirm your specific truck model and air dryer assembly before ordering.

What’s the difference between this and the desiccant version (BA5374)? The BA5379/21620181 is the coalescer version, designed primarily to separate moisture and oil from compressed air. The related BA5374 is a desiccant version, which uses a different media designed to actively absorb moisture. Confirm which type your air dryer assembly requires before ordering.

Do you offer samples before a bulk order? Yes. We recommend requesting a sample for independent testing before committing to a bulk order, especially for first-time buyers.
