Ingersoll Rand N4 98%- 99% Nitrogen Generator

Ingersoll Rand N4 98%–99% PSA Nitrogen Generator

The Ingersoll Rand N4 98%–99%, part number 47860293001, produces gaseous nitrogen on site from clean, dry compressed air using Pressure Swing Adsorption (PSA). This listing covers 98% – 99% nitrogen purity, with published output of 14.7–18.6 Nm³/h across the listed purity settings. On-site production allows nitrogen supply to be matched to the facility’s operating requirements.

Generation technology and controls

• PSA separates nitrogen from compressed air through alternating adsorption and regeneration cycles.
• A built-in purity analyser monitors gas quality, while touchscreen controls support operation.
• Automatic start/stop responds to nitrogen consumption.

Technical specifications

Nitrogen output by purity setting

Manufacturer N-series performance data are based on 7 bar(g) inlet pressure. Flow is shown using the manufacturer’s Nm³/h designation; the technical sheets reference gas volume at 20°C and 1.013 bar(a). The output at one purity setting must not be assumed at a higher purity.

Feed-air preparation and installation

The N-series brochure specifies inlet air quality ISO 8573-1:2010 Class 1.4.1. Select the air compressor, dryer, filtration and storage together to maintain the required inlet condition and pressure throughout the PSA cycle.

Provide the required electrical supply, ventilation, receiver capacity and service access for the selected package. Confirm purity monitoring, operating alarms and the response to off-specification gas during system selection.

Purity, capacity and system selection

Select the required nitrogen purity first, then size the generator for average demand, peak demand and delivery pressure. Higher purity reduces the available nitrogen output and changes the compressed-air requirement. Include feed-air and nitrogen storage in the system design.
