Our Best Selling Model
The OG-15 extracts oxygen from the atmosphere, concentrates it up to 95% purity, and delivers the oxygen to any application.

Dependable
The OG-15 is completely self-contained. Its internal air compressor, filtration system, zeolite sieve, surge tank, and flow control system were designed for 24 hour operation.

Durable
The OG-15 is built on a powder coated steel chassis. Its anodized aluminum sieve beds are fitted with custom molded composite end caps for years of reliable service. Weighing almost 73 lbs (33kg) the OG-15 is the industrial strength oxygen concentrator.

Safe
Why bother with the danger of high-pressure cylinder oxygen? The OG-15’s built-in regulator allows you to set the delivery pressure according to your needs. The 1/3 Horsepower compressor maintains an internal pressure of less than 32 psi, and delivers an optimal flow of oxygen from 1-12 psi.

Economical
Oxygen is free! Eliminate the unnecessary costs of transportation, storage, and cylinder rental. The OG-15 uses less than 1/2 kilowatt of electricity to deliver up to 15 cubic feet of oxygen per hour.

Simple to Use and Maintain
With a lighted on/off switch, integrated control panel, digital hours meter, custom flow gauges and controls, the OG-15 is truly user friendly. Just plug it in, turn it on, and set the desired pressure and flow. Check and/or replace the inlet air filter every 6 months, and you’re done. The zeolite sieve (which actually separates oxygen from nitrogen) is regenerative, and does not need to be replaced for the life of the unit under normal operating conditions.)
