OG-15 Oxygen Concentrator will take ambient air and concentrate the oxygen already present with a compact turnkey device.

The OG-15 is completely self-contained in a great looking powdercoated enclosure. It produces up to 15 standard cubic feet per hour (SCFH)/ 7.5 liters per minute (LPM) at  up to 15 PSI, with oxygen purities up to 95%. The OG-15 built for 24 hour operation.  The total industrial strength and quality of the OG-15 will provide the end-user with years of dependable, reliable, and virtually maintenance-free operation. 

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 78 lb (35 kg) the OG-15 is the industrial strength oxygen concentrator.

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 0.3 hp compressor maintains an internal pressure of less than 9 psi, and delivers an optimal flow of oxygen up to 12 psi.

Oxygen is free! Eliminate the unnecessary costs of transportation, storage, and cylinder rental. The OG-15 uses less than 0.7 kW of electricity to deliver up to 15  standard cubic feet of oxygen per hour (SCFH). This product is cost effective and energy efficient.

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, place the on/off switch in the “on” position, and set your oxygen delivery flow and pressure. The molecular sieve/zeolite (which separates the oxygen from nitrogen) is regenerative, and should not need to be replaced for the life of the unit under normal operating conditions.
