Description
The Power Products 065612P is an aftermarket AD-IP-style air dryer assembly for heavy-duty trucks, tractors, and buses, replacing Bendix 065612 and 109477 as well as Meritor R955065612 and R955109477X. The unit clears moisture, oil mist, and particulates from the air-brake system through a desiccant cartridge, hard-seat purge valve, and integrated 12 V / 90 W heater for cold-weather operation. Mounting bracket included.
Signs You Need a New Air Dryer
- Water or oil discharged from purge valve continuously, or no purge cycle at all
- Air-brake compressor cycling more often than normal
- Moisture in the supply tank or air-system lines
- Visible cracks, corrosion, or damage to the dryer body or end cover
- Heater fails to keep purge valve from freezing in winter
