Technology Options

PSA systems utilize carbon molecular sieves to separate nitrogen from compressed air. The process cycles between adsorption and regeneration phases, producing nitrogen purities from 95% to 99.999% depending on application requirements. Ideal for applications demanding high purity or variable flow rates with rapid response.

Membrane systems employ hollow fiber membranes that selectively permeate oxygen, water vapor, and CO₂ while retaining nitrogen. Simpler operation with no moving parts in the separation stage produces nitrogen purities typically 95-99.5%. Best suited for moderate purity requirements with steady flow demands and lower maintenance preferences.
