An air suspension system is a kind of automobile suspension that replaces steel springs used in conventional suspension systems with air bags/springs. An air compressor, which is an electric pump, delivers compressed air to the springs via a series of compressed air lines. The air suspension system also includes a dryer, usually attached to the compressor, to prevent any moisture from entering the springs.
