Used OG-50

Used OG-50 Oxygen Generator is an industrial oxygen concentrator great for continuous oxygen production.  Compressed air must be supplied to the OG-50.  This compressed air is separated via Pressure Swing Absorption (PSA) technology.  Oxygen is captured in a storage tank and can be supplied to the point of use at any flow rate required up to 50 SCFH at pressures of 45 - 60 PSI.

Features:

OG-25 and OG-50 units are built to provide thousands of hours of continuous, reliable service. The Zeolite sieve is factory sealed in solid steel tanks and rarely needs replacement. With very few moving parts, our generators are built to provide thousands of hours of continuous, reliable service Routine maintenance is as simple as changing an air filter.

OG-25 and OG-50 units have precision-welded tank assemblies (ASME coded) and oxygen-clean brass tubing and valves which allow them to operate in extreme conditions.

Every PLC-controlled generator is assembled and tested in our North Tonawanda, NY production facility.

What is Pressure Swing Adsorption (PSA):

Clean, dry compressed air is fed into the first molecular sieve bed.  Nitrogen is adsorbed, while oxygen is allowed to flow through.  When the sieve in the first bed becomes full of nitrogen, the airflow is then directed into the second bed.  As the second bed separates the oxygen from the nitrogen, the first bed vents its nitrogen into the atmosphere.  Compressed air is once again fed into the first bed, and the process is repeated continuously.  A constant flow of oxygen is reliably produced.

The OG-50 Oxygen Concentrator requires compressed air for operation.  Typical installation of entire system is outlined below. 

- Air compressor will provide at least 12 CFM compressed air at 90PSI or greater

- Particulate filter will remove most dust, and oil from air stream

- Refrigerant air dryer is used to remote moisture from air and provide 40-deg F dew point

- Coalescing filter will remove any final oil mist and moisture from air flow

- Air storage tank is necessary to provide sufficient air storage for oxygen generator purging

- Oxygen Generator will purge nitrogen from air and capture oxygen

- Oxygen storage tank will store oxygen and provide consistent oxygen flow and pressure to point of use

- We also suggest installing an oxygen filter downstream of the oxygen storage tank to filter any zeolite dust from the oxygen concentrator

External components of the OG-50 shown below.  OG-50 is a simple system to install and operate.

Control cabinet of the OG-25 houses the PLC controller and all components.  All components are simple and reliable.  Every part on this oxygen concentrator is rebuildable or repairable.  This is a machine that will serve your operation for as long as you wish.
