What Is a VPSA Oxygen Generator?
A vacuum pressure swing absorption or VPSA oxygen generator is one
of the more effective tools at extracting oxygen from the
atmosphere around us.
The VPSA can extract oxygen from the ambient air stream by
absorbing one of the most common elements in the air around
us—nitrogen—thus producing a flow of purified oxygen. For higher
volumes, the VPSA is very effective.

How VPSA Oxygen Generation Works
Vacuum pressure swing adsorption (VPSA) is a technology effectively
separating oxygen or nitrogen from atmosphere using molecular
sieves.
Features
The unit energy cost will decrease as the increase in oxygen
production volume.
Adopt Roots blowers and Roots vacuum pumps, which are both based on
volumetric and oil-free operation, and easy to maintain.
The whole system is highly-integrated, the power system and oxygen
generator are synthesized, enabling one-click start.
Suitable for medium to large production volume
Adsorbing process can be automatically controlled by PLC system and
switch valve.
Oxygen Generation Process
- Ambient air treatment After removed from dust particles by the
inhalation filter, the atmospheric air will be compressed to
0.3-0.5 barg by the Roots blower and then flows to one of the ZMS
adsorb tower. The CO2 will be adsorbed by the activated alumina
filled at the bottom at the inlet of the adsorber. As nitrogen has
a higher diffusion rate in ZMS pores, the sieve will adsorb the
nitrogen and moisture over oxygen, allowing the oxygen to be
collected as product gas at pressure.
- Separation of oxygen Non-adsorbed air such as oxygen and argon will
escape from the outlet of the adsorber into the oxygen buffer tank
as product gas.
- Depressurization of the adsorber When the adsorber is
fully-adsorbed, the valve should be switched to the opposite
direction to depressurize the adsorb tank to 0.65-0.75 barg by the
vacuuming pump, to desorb the sieves for reuse. The adsorbed
moisture, CO2, nitrogen and other gas will be released into the
atmosphere.
