What is an Air Bag Suspension?
An air bag suspension system is powered by either an electric pump or compressor that forces air into rubber bags typically made out of polyurethane and textile-reinforced rubber. A compressor inflates the air bags to a certain air pressure. It’s important to note that it’s the air inside the bag that does the work of a spring. (An air bag suspension should not be confused with a hydropneumatics suspension which uses pressurized hydraulic liquid instead of air.)
