Ingersoll Rand O9 PSA Oxygen Generator – 47936628001

The Ingersoll Rand O9 PSA Oxygen Generator, part number 47936628001, produces industrial oxygen on site from clean, dry compressed air. Pressure Swing Adsorption (PSA) provides oxygen at 90%, 93% or 95% purity to suit the process. At 95% purity, this model has a nominal output of 3.44 m³/h under the datasheet reference conditions.

O9 PSA Oxygen Generator Features

• Colour touch screen control
• Built-in purity analyzer for continuous monitoring
• Data logging via USB interface
• Modbus TCP Ethernet connection
• Remote start/stop relay
• Stainless steel piping
• Designed for dynamic pressure loading

O9 Oxygen Output and Compressed-Air Requirements

Flow values use the model datasheet reference conditions of 20°C and 1.013 bar absolute. Rated inlet pressure is 7 bar(g), with rated oxygen outlet pressure of 4 bar(g). Select the operating purity to match the process; available output depends on the operating conditions.

• Clean, dry compressed-air consumption at the generator inlet: 43.08 m³/h.
• Minimum feed-air quality: ISO 8573-1:2010 Class 1.4.1.
• Model datasheet inlet pressure range: 7–11 bar(g); oxygen outlet pressure range: 4–8 bar(g).
• Compressed-air inlet and ambient temperature range: 5–50°C.
• Minimum buffer tank size listed for this model: 150 litres; tank supply and configuration are confirmed with the system quotation.

Use correctly sized air drying and filtration upstream of the generator. Confirm compressor capacity, operating pressure, site conditions and required oxygen storage with AVISTA before ordering.

Oxygen Monitoring and Control

The model datasheet specifies a zirconium oxygen-purity sensor, a Siemens S7-1200 PLC and a KTP400 4-inch touch screen. A dew-point sensor and off-spec bypass protect the molecular sieve against excessive moisture in the feed air. USB logging records purity and pressure for operating checks.

Industrial Oxygen Applications and System Selection

Industrial applications include fish farming, glass and metal processing, gold leaching, ozone production, water treatment, cutting and welding. Select the generator and compressed-air preparation system according to required oxygen flow, purity and operating conditions.
