Without air, your new air ride suspension will be just about useless and considering the amount of money you spend on it, why let the bags stay deflated. The air compressor fills the air tank with air that will eventually be used to inflate your air bags. The air tank will be available in several configurations, depending on the size of your vehicle.Air ride tanks that are to be used in an air suspension application need to be able to handle at least 150psi of air pressure. "Approved" tanks are pressure tested after being made by the manufacturer to be certain that they are leak free and able to withstand the high pressures of air ride suspension. When you buy a tank from Air Lift, you can be sure that these tanks have been tested over and over again to ensure their quality.
