Air tanks are an important component in the air systems of heavy-duty trucks, buses, and trailers. The air tanks or reservoirs store large volumes of compressed air which is used to operate the suspension, brakes, and many accessory systems. The air system on the truck allows the engine driven compressor to fill the tanks in a cycle instead of running constantly. When a trailer is connected, the truck will also be responsible for filling the trailer tanks. By having a large air volume on hand in the air tanks, the systems driven by air can react instantly instead of waiting for the compressor to catch up.

Air tanks not only provide convenience, but they provide safety through the braking system. FMVSS 121 is the Federal Motor Vehicle Safety Standard that outlines the requirements for the air system including the volume requirements for trucks and trailers. For trucks and buses, the total reservoir volume (combined volume of primary, secondary, and supply reservoirs) should be at least 12 times the combined volume of all the service brake chambers on the vehicle. For trailers, the requirement is eight times the volume of all the service brake chambers. This allows for multiple controlled brake applications even after an air supply has been lost.
