About OGSI

Oxygen Generating Systems Intl. (OGSI), a member of Novair Group, designs and manufactures oxygen generators. Using PSA technology, OGSI offers a complete line of on-site oxygen generator (OG) plants with outputs from 15 (7.5 LPM) to over 5000 SCFH (5tpd) with an oxygen purity of 93% (+/- 3%). Using only air and electricity, OGSI can help you generate on-demand oxygen 24x7x365.

OGSI also offers complete oxygen generators with cylinder filling plants (CFP’s) that can fill from from 1 to 180 cylinders filled per day. We also produce compact plug and play oxygen generators, powerful mobile oxygen generating systems (MOGS), oxygen generators in trailers and containers, and tailor-made solutions.

By dumping costly oxygen cylinder distributors and switching to self-generating oxygen equipment, you start saving money in a short period of time. OGSI can find the perfect fit to produce life-saving oxygen for those in hospitals, firefighting & EMS, emergency & disaster response, and veterinary clinics. We also generate large amounts of economical oxygen and ozone for abatement & emissions control as with semiconductor fabrication, wastewater treatment, aquaculture/fish farming, and many other uses. 

We even service and offer replacement parts for many of our competitors’ products.
