Air Suspension

An air suspension system is a style of vehicle suspension that's powered by an electric pump or compressor that pumps air into supple bellows that are typically made out of a textile-reinforced type of rubber. Air suspension is described as a replacement to the leaf suspension or coil spring system with airbags composed of polyurethane and rubber. A compressor aerated the bags to a certain pressure in order to behave like springs. Air suspension also diverge from hydropneumatic suspension because it uses pressurized air instead of pressurized liquid.
