Page 9: Pressure Swing Adsorption (Psa) Technology
Pressure Swing Adsorption (PSA) Technology The OGSI Oxygen Generator is an on-site oxygen-generating machine capable of producing oxygen on demand in accordance with your requirements. It requires less than 600 Watts of electrical power to control its operation. In effect, it separates the Oxygen (21% of air) from the air it is provided and returns the Nitrogen (78% of air) to the atmosphere through a waste gas muffler.

Page 11: Required Operating Conditions
Note: Operation outside of this temperature range will not be warranted by OGSI. Feed Air Requirements: The pressure of the incoming feed air supply should be at least 90 PSIG (620 kPa).
Page 12 Pipe scale, oil carryover from the compressor and water vapor should all be minimized to ensure long and trouble-free Oxygen Generator operation. These things can be accomplished with a few regular procedures. First, it is important to recognize that the air compressor is a critical component in the Oxygen Generating process.
Page 13: Typical Setup Diagrams
Typical Setup Diagrams Shown immediately below is a sample drawing that depicts how a typical system could look when connected. Occasionally a user may choose to maintain a liquid or cylinder backup and keep it connected to his system for critical applications. This is a precaution that ensures uninterrupted oxygen flow if the power supply should be lost or the compressor or generator malfunction.
Page 14: Pre-Installation Check
Pre-Installation Check Instructions Although every Oxygen Generator is thoroughly tested and checked before it is shipped from our factory, the following checks are necessary to insure that none of the internal components have been damaged in shipment. This check should take less than five minutes to perform.

If you do not have a valve on hand at this time, skip this step as one can be installed at this point at a later date. OGSI does stock valves that can be used for this purpose. If you need one you can reach our sales department at (716) 564-5165.
Page 19 5.) Connect Your Oxygen Hose to the Oxygen Pressure Regulator on the Oxygen Storage Tank - If you are using an Oxygen Manifold as in one of the previous drawings, we recommend another ball valve between the hose that is connected to the Oxygen Regulator and the Oxygen Manifold.
Page 20: Safety Precautions
Safety Precautions It is very important that you read the precautions below and make yourself aware of the hazards of oxygen in general. While it can be handled and used very safely it can also be mishandled or applied incorrectly causing dangerous situations. 1.) Oxygen is a fire hazard.
Page 21: Start Up Procedures
Start Up Procedures Prior to attempting to run the Oxygen Generator it is important to check to connections that have been made to it. Make sure that they are all tight as leaks will be detrimental to the generator’s performance and increase your operating expenses. Also be sure to review the ‘Setup Instructions’...
Page 22 4.) If the Storage Tank Pressure is Above 30 PSIG (210 kPa), the Generator Switch can be Immediately Turned to ‘Automatic’ - This should be the case upon arriving in the morning to a system that was properly shut down the evening before or after starting up the first time and having vented the storage tank down to 40 PSIG (280 kPa).
Page 23: Shut Down Procedures
Shut Down Procedures Following these few simple steps will allow you to avoid having to run the generator while venting the storage tank every day or every time you want to use it. 1.) Close the Valve that Allows Oxygen to Flow to Your Manifold or Application -This will keep the storage tank from being depressurized while oxygen is not being used.
Page 24: Troubleshooting Guide
Troubleshooting Guide No Power: 1.) Ensure that power is available from the 110 vac supply 2.) Visually inspect the electrical wiring. Reconnect any loose wires to their appropriately labeled location. Oxygen purity is low: 1.) Check the system for leaks, using a leak testing solution. 2.) Ensure that operating environment is conducive to oxygen generation.
Page 25: Detailed Warning Description
Detailed Warning Description Thermal switch The appropriate thermal overload switch must be Warning reset (by pressing it), and the “Clear Warning” pushbutton (touchscreen option)- must be pressed. Normal operation can then be resumed. Pressure Switch If the pressure switch has tripped, this is an indication Warning of the high pressure transducer failure.

Page 28: Process Flow Description
Process Flow Description The normal flow of air through the Oxygen Generating System is shown on the previous 2 pages in the Process Flow Schematic Drawings. As you can see once the incoming air is filtered and compressed to proper pressure it is directed into one of the two sieve beds.

A hose or pipe should be attached to this fitting. It should be of adequate diameter to supply air at a sufficient pressure and flow rate to feed the generator. OGSI can assist in sizing this line, if necessary.
Page 31 Hose Assembly should be connected to the inlet fitting of the Oxygen Storage Tank that you are using. If the storage tank was purchased from OGSI, it will have an appropriately sized fitting in place for this connection. If the tank was not...
Page 32 Oxygen Regulator - If your storage tank came from OGSI, there will be an Oxygen Regulator, which you should attach to it. It can be used to set the regulated Oxygen pressure out of the storage tank at any level up to 60 PSIG (420 kPa). Please keep in mind that our specification for the maximum oxygen pressure available from a system is 45 PSIG (310 kPa).

Page 35 The noise muffler is used to silence the exhaust noise that occurs as a result of the sieve beds rapidly depressurizing to atmospheric pressure, venting their nitrogen. For installations where a lower noise level is required, OGSI offers an optional alternative muffler system that can decrease the emitted noise even further.

Manifold Operating Procedures Warning: High Pressure Oxygen may present a Hazard. Always follow proper operating procedures, and open valves slowly. Rapid pressurization may result in personal injury. Safety glasses and hearing protection are required when venting oxygen under high pressure. Attaching and filling a K-type cylinder: With all valves initially closed, connect the steel whip between a manifold valve and a cylinder valve, and tighten both connections using a 1 1/8”...
Page 51: Routine Maintenance
Routine Maintenance Instructions Filter Drain: Make sure the filter drain is working properly and not blocked by anything. When the unit first begins to cycle in the morning the filter drain should open for 5 seconds and then for 5-second periods once every 15 minutes. Do this daily. Filter Element Replacement: The filter element provided with the Oxygen Generator must be replaced every six (6) months.
Page 52: Filter Element Replacement Instructions
Filter Element Replacement Instructions 1.) Place the Generator in the ‘Continuous’ Mode 2.) Close the Valve that Supplies Air to the Generator 3.) Press the Manual Filter Drain Push Button until the Regulated Air Pressure Gauge Reads 0 PSIG 4.) Place the Generator in the ‘Off’ Mode 5.) Open the Cabinet Door 6.) Disconnect the Plastic Tube from the Brass Prestolok Fitting holding it in Place.
