At On Site Gas, we utilize Pressure Swing Adsorption (PSA) technology for oxygen generation. This method uses variations in pressure to create concentrated oxygen.
Oxygen generation with PSA technology has the ability to create oxygen with a 95 percent purity. This is accomplished with our Pure Convenience line of PSA oxygen gas generators. In order to achieve higher oxygen levels, our PSA oxygen generators remove the nitrogen via a molecular sieve filled with pressurized air. As the pressure increases, the sieve absorbs the nitrogen and vents it out. The remaining oxygen is moved to a storage tank where it can be used for various commercial and industrial applications.
