170.065225
The Automann 170.065225 is a complete AD9-type air dryer assembly that removes moisture and contaminants from a heavy-duty truck's compressed air system. It protects air brake components from corrosion and ice build‑up, ensuring reliable braking performance. This aftermarket unit replaces Bendix AD9 dryers and is commonly refreshed when the desiccant cartridge becomes saturated, the purge valve fails, or during preventive maintenance of the air system.
Universal fit
Direct replacement for vehicles originally equipped with a Bendix AD9 air dryer (using mounting bracket kit 170.107695 if needed). Commonly found on class 8 trucks including certain Mack, Freightliner, International, and Volvo models that spec'd the AD9 system. Verify physical mounting and port orientation before installation.
