Evolved from the extremely popular OG-15 model, the OG-20 extracts oxygen from the atmosphere, concentrates it to 93% (± 3%) purity, and delivers the oxygen to any application. The OG-20 offers up to 25% more oxygen flow rate and delivery pressure.


The OG-20 is completely self-contained, and its overall design is built for 24 hour operation. It produces up to 20 standard cubic feet per hour (SCFH)/ 10 liters per minute (LPM) at 1-20 PSIG, with oxygen purities up to 95%. The total industrial strength and quality of the OG-20 will provide the end-user with years of dependable, reliable, and virtually maintenance-free operation.


The OG-20 is built on a powder coated steel frame/chassis. Its internal air compressor, aluminum sieve beds with state-of-the-art molecular sieve material, filtration and flow of control systems are designed for years of continuous and reliable service. Each OG-20 goes through rigorous quality control testing procedures. Weighing only 80 lb (36 kg) the OG-20 is available in 115 VAC/60 HZ, 230 VAC/50 HZ and 230 VAC/60 HZ models for use worldwide!


Whether you are dissolving high levels of O2 for your fish farm or boosting cell productivity in systems such as Wave Bioreactor cell culturing equipment, the OG-20 can deliver oxygen to your application.


The OG-20 is being used more and more as an alternative to using high pressure, dangerous, and costly cylinder/liquid oxygen. Bottom line... saving the end user significant dollars on their oxygen costs. The OG-20’s built-in adjustable regulator allows you to set the oxygen delivery pressure according to your requirements. The 0.3 hp oilless piston air compressor maintains an internal pressure of less than 32 psi and delivers an optimal flow of oxygen at up to 20 PSIG.


Oxygen is free! Eliminate the unnecessary costs of transportation, storage, and oxygen cylinder/liquid rental. The OG-20 uses less than 0.7 kW of kilowatt electricity to deliver up to 20 SCFH of oxygen.

Simple to Use and Maintain

With a lighted on/off switch, integrated control panel, digital hours meter, custom flow gauges and controls, the OG-20 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.

Original Equipment Manufacturer (OEM) Configurations

For integrators, the OG-20 OEM is available. This basic configuration includes the sieve beds, timing board, and a valve secured to a mounting plate for easy installation in the purchaser's enclosure. The benefit of this OEM design is it provides a lower cost option to customers who want to supply their own feed air, instrumentation, and enclosure for a total oxygen producing package to end users.
