Air Drier

Attached to the air suspension compressor is the air drier which contains a desiccant for removing moisture from the compressed air. Pressurized air is passed through the air drier 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 drier, removing the moisture from the unit and regenerating the desiccant.

The air drier 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 make sure the air drier continues to perform correctly, the following are essential during servicing when:

NOTE: These steps are required only when the air suspension system needs de-pressurizing during servicing.

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