Bendix AD-SP Air Dryer

Replacement AS-SP style air dryer. Clean, dry air lines help keep you on the road and out of the shop. The air dryer (installed between the compressor and reservoirs) collects and removes solid, liquid, and vapor contaminants before they enter the air brake system and compromise efficient operation. A new air dryer provides clean, dry air to reservoirs, valves, and other components, which increases the life of the air brake system, helps reduce maintenance costs, and prevents system freeze-up. 12 volt.
