The Peerless PHP15 Petrol Air Compressor Belt Drive Under & Over Design – for High Pressure – 17 CFM / 320LPM is a 6HP Honda engine high pressure compressor capable of running at 175PSI. These machines are fantastic for tyre inflation i.e.. truck tyres or applications where large volumes of air at high pressure is required. The advantages of a two stage compressor is that you do not lose volume of air at higher pressure. The air temperature is some 40% cooler than the standard type of air compressor therefore producing less condensation.
