Air Dryer: Description and Operation
AIR DRYERThe air dryer is connected into the air line between the compressor and reservoir. It is mounted on the engine air cleaner box. The dryer removes moisture from pressurized air entering the system. All air exhausted from the system passes through the dryer in the opposite direction. The air dryer is regenerative in that exhaust air absorbs moisture in the dryer and expels it to atmosphere.
The air dryer is non-serviceable, designed to last the life of the vehicle. However, if any water is found in the system, the air dryer must be replaced.
CAUTION: If the air dryer is removed from the vehicle the ports must be plugged to prevent moisture ingress.
