Pacific Consolidated Industries (PCI Gases)  was founded in 1984 and has corporate headquarters along with manufacturing facilities in Riverside, California. PCI Gases is a global leader in the design and manufacture of on-site oxygen and nitrogen generators. These generators are popular in the military, oil & gas, commercial, and industrial markets.

​

Each PCI Gases product targets applications where distributed industrial gases are either too expensive or difficult to obtain. PCI Gases has developed robust platforms to include all three point-of-use air separation technologies. These exciting technologies are cryogenics (liquid oxygen and nitrogen), membranes (gaseous nitrogen) and vacuum swing absorption (gaseous oxygen). Domestically producing these gases helps the environment while cutting costs by effectively eliminating the logistical supply chain. PCI Gases is at the forefront of advancing air separation technology with thousands of systems built that are actively operating and supported in over 50 countries worldwide.

​

PCI Gases maintains a quality system registered with the British Standards Institute (BSI), in accordance with ISO 13485:2003 for the design, manufacture, distribution and aftermarket services of oxygen concentrators for medical use, and ISO 9001:2008 for the design, manufacture, distribution and aftermarket services of oxygen concentrators for industrial use.
