It’s a reliable and economic solution for on-site production of high purity oxygen/nitrogen. Generally economical for larger systems, this technology utilises vacuum cycles to the better known PSA technology.

Vacuum swing adsorption (VSA) is a non-cryogenic gas separation technology. Using special solids, or adsorbents, VSA segregates certain gases from a gaseous mixture under minimal pressure according to the species’ molecular characteristics and affinity for the adsorbents. These adsorbents (e.g., zeolites) form a molecular sieve and preferentially adsorb the target gas species at near ambient pressure. The process then swings to a vacuum to regenerate the adsorbent material.

AirPro’s Oxygen and Nitrogen Generators with VSA technology are among the most efficient and dependable generators available today.
