The Coltri/Nuvair MCH6 Portable compressor is a standalone, four-stage high pressure (4500 psi / 310 bar) compressor made for filling scuba, SCBA or paintball cylinders/tanks on the go. Powered by a gas engine or an electric single- or three-phase motor, the MCH6 is ideal for filling cylinders at home, on boats, at the paintball field or on scene of an emergency incident.
The MCH6 Portable compressor is designed for filling scuba, SCBA, or paintball cylinders/tanks one at a time. The compressor was not engineered or manufactured for continuous duty filling of storage tanks or cascade storage systems of any kind. MCH6 Portable compressors are lighter and have a smaller footprint than the MCH6 Compact compressor line. The size and weight of this compressor make it very easy to transport and operate. Fill an 80 cu ft scuba tank in about 19-23 minutes based upon power source. Fill hose and air filtration system included.
