This efficient and economical ,OGS-20 oxygen generator uses Pressure Swing Adsorption Technology (PSA) to deliver a constant flow of up to 20 SCFH (9 LPM) of medical grade oxygen at a pressure of up to 90 psi; making it ideal for Veterinary Clinics/Offices. Let’s sail through some of its awesome qualities: Dependable: It is very dependable as every oxygen generator is assembled and tested in our New York State production facility. The OGS-20’s internal air compressor, filtration system, zeolite sieve, surge tank and flow control system were designed for 24/7 operation.

They even operate in the harsh environments of Africa, Asia, South America and the Yukon. Economical: Well, we all know Oxygen is free! Eliminate the unnecessary costs of transportation, storage, and cylinder rental. The OGS-20 uses less than 1.1 kW of electricity to deliver up to 20 ft.3 of oxygen per hour. Simple to Use and Maintain: With a lighted on/off switch, hours meter, custom flow gauges and controls, the OGS-20 is truly user-friendly. Just plug it in, turn it on and set the desired pressure and flow and you’re done. Automatic Operation: Automatically starts and stops based on the need for oxygen and the pressure in the storage tank.
