Air Dryer

Attached to the compressor is the air dryer which contains a desiccant for removing moisture from the compressed air. Pressurized air is passed through the air dryer which removes any moisture in the compressed air before it is passed into the suspension system.

When the air springs are deflated, the exhaust air passes back through the air dryer, removing the moisture from the unit and regenerating the Desiccant.

The air dryer is an essential component in the system ensuring that only dry air is present in the system. If moist air is present, freezing can occur resulting in poor system operation or component malfunction or failure.

To ensure the air-dryer continues to perform correctly, it is essential during servicing, that

• the affected air springs are deflated using the correct deflation procedure
• air is removed from the air reservoir using the correct procedure.
