Air Dryer AD-9
Bendix

Standard AD-9 type dryer unit provides reliable moisture control for heavy-duty pneumatic systems. This model adheres to common AD-9 specifications, ensuring compatibility with widely used spin-on housings and desiccant media. The dryer’s design emphasizes steady dew point control, minimizing ice formation and condensate carryover that can compromise braking performance and solenoid reliability. VMRS 013-010-252 positions it within the air dryer family, enabling consistent maintenance planning alongside other dryers in the vehicle’s pneumatic train. Cross references and fleet substitution options exist to support quick replacements during scheduled maintenance or roadside service. In practice, this unit supports improved air cleanliness, reducing the risk of corrosion and sticking in control valves, and contributing to more reliable pedal feel and brake response across temperature swings and heavy-haul duty cycles.
