Frequently Asked Questions

What is a PSA Nitrogen Generator?

PSA (Pressure Swing Adsorption) nitrogen generators use carbon molecular sieves to separate nitrogen from compressed air, producing high-purity nitrogen gas for industrial use.

How does a Membrane Nitrogen Generator work?

Membrane systems use hollow-fiber membranes to separate nitrogen from air based on differential permeation rates, ideal for continuous, low-maintenance operation.

Can I get a custom nitrogen system?

Yes. We offer fully customizable nitrogen, oxygen, and hydrogen generation systems tailored to your flow, pressure, purity, and space requirements.

Do you provide installation support?

We offer remote technical guidance and documentation. On-site installation support can be arranged upon request.

What industries use your generators?

Our systems are used in pharmaceuticals, food & beverage, electronics, oil & gas, metallurgy, laboratories, medical facilities, and more.
