Roots Blower and Vacuum Pump for VPSA System

VPSA（Vacuum Pressure Swing Adsorption）is a non-cryogenic gas separation technology that uses special solids (adsorbents) as molecular sieves to segregate the Nitrogen and Oxygen from the mixture of air. Roots Blower and Vacuum Pump are the main equipment for the VPSA system.

Vacuum Pressure Swing Adsorption (VPSA) is an advanced gas separation technology that utilizes the different selectivity of adsorbents for gas molecules to separate gas components. Based on the principle of VPSA technology, the VPSA-O2 units adopt the special adsorbent to enrich the oxygen in the air and supply it to the user.

VPSA Working Principle

Firstly to remove mechanical impurities with filter. After desorption, a Roots Blower blows The VPSA-O2 into the adsorption vessel of the VPSA-O2 system. The adsorber is a double-vessel system, and its product is oxygen. It will absorb Nitrogen, carbon dioxide, and water vapor in the air. After saturated adsorption, a vacuum pump will work to desorb the adsorbents in the adsorption vessel completely for regeneration. The double-vessel VPSA-O2 system ensures continuous oxygen generation through the cyclic switch of the program control valve under the control of PLC (data control system).
