Nuvair set out to develop a flagship continuous duty commercial high pressure compressor when we came up with open horizontal models. Available in three models, the open horizontal packages are built around the Coltri four-stage compressor block and can pump up to 27 SCFM* (764 L/min) at 6000 psi (414 bar) when charging cylinders. The Coltri compressor block and a WEG TEFC motor are mounted on to a stainless steel plate that is placed into a marine grade aluminum frame with belt guard. All packages come with two filters (combined for 60,000 cu ft of Grade E filtration), auto condensate drains, loadless start, independent vibration isolators, NEMA 4 motor starter box, enclosed drip pan and four point lifting eyes.
