Abstract
A method of supplying a higher pressure air supply to a lower pressure air supply comprising a primary air supply tank, maintained at a first higher pressure by a compressor, continuously fluidly coupled to one or more secondary air supply tank(s) through a pressure reducing valve, maintained at a second, lower pressure to the pressure of the primary air supply tank. In this way the primary tank serves as a higher pressure reservoir and increases the efficacy of the secondary air supply tanks.
