We have lovely METAL compressors for air suspension. They vary from our superb 200psi, 100% duty cycle at 100 psi units pictured down to the trailer and van units at 120 psi 15% duty cycle. All compressors are specifically designed for use as suspension compressors and are not recycled tyre inflation units. We recommend the high spec units for most applications. They are a better specification that the compressors used on new range rovers and other high end prestige cars.
