Made for car suspension and other pneumatic needs, the VIAIR 444C Dual Performance Compressor Value Pack is ready to give you air where you need it. This dual compressor kit is built to attach onto all kinds of vehicles such as cars, fire trucks, and even trains. You can attach them just about anywhere, but it's recommended that you keep them close to the vehicle's battery. They should also be kept somewhere inside the vehicle to keep it out of direct rainfall. The 444C Air Compressor is able to run directly off of your vehicle's battery. That way you don't have to worry about keeping it filled with gas or changing its oil. It also means you don't have to spend time charging the compressor since your vehicle will always be able to supply the energy it needs. To keep the compressors in good shape, an automatic thermal overload protector shuts off the system if it's pushed past its limit. That said, the compressors are made to generate a lot of power without overheating. In fact, they can run continuously at 100 PSi. If you don't mind some downtime, they can actually generate much more pressure, up to 200 PSI. With that kind of output, you can power air horns, air ride suspension systems, and even light pneumatic tools. Use a compressor that will work wherever your vehicle is with the VIAIR 444C Dual Performance Compressor Value Pack.
