Coltri / Nuvair 3E High Pressure Portable Breathing Air Compressor
The sturdy enclosure and easily accessible lifting handles on this series of compressors makes it ideal for portable applications. It is available in a full range of electric and gas power for filling cylinders at home, at the dive shop or on boats.


MCH6 Portable compressors are lighter and have a smaller footprint than the MCH6 Compact compressor line.

The MCH6 is designed for filling SCUBA, SCBA or paintball 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.

The compact dimensions and light 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.
