99.99~99.999% high purity PSA Industrial nitrogen generator nitrogen system

PSA nitrogen generator (Pressure Swing Adsorption Nitrogen Generator) is a device that uses the pressure swing adsorption principle to separate high-purity nitrogen from compressed air.

  • Working Pressure:6[ bar ]87[ psig ]
  • Free Air Delivery:12.4~88.3[ cfm ]0.35~2.5[ m3/min ]
  • Working Power:0.1~0.15[ kw ]0.13~0.2[ hp ]

Product features

• Low-cost operation: This is the core advantage. Once the equipment is operational, the primary cost is electricity (to drive the air compressor).

• Flexible purity and flow rate adjustment: Users can flexibly set and adjust nitrogen purity within a certain range (e.g., 95% to 99.9995%) to meet 

their process requirements.

• Safety and reliability: Eliminates the safety risks associated with handling high-pressure cylinders or cryogenic liquid nitrogen tanks. Nitrogen is 

generated at low pressure, providing enhanced safety.

• Energy conservation and environmental protection: Carbon emissions associated with transporting cylinders or liquid nitrogen tanks are avoided. 

Energy consumption during container manufacturing is also eliminated, resulting in a lower overall carbon footprint.
