Frequently Asked Questions

Nitrogen from INMATEC can reach a purity grade of 90.0 up to 99.9999%. The oxygen purity is “only” about 90.0 – 95.0%. The difference is this large because the requirements of the users of PSA generators in the individual sectors differ greatly for nitrogen or oxygen purities.

The PSA technology is based on the adsorption principle: The nitrogen molecules and oxygen molecules of the incoming air are separated by a carbon molecule sieve. The nitrogen molecules or oxygen molecules flow through the carbon. They are led into a large container or system tank by compressed air and collected. The highly pure nitrogen or oxygen are available there for further use.

The term Pressure Swing Adsorption (PSA), stands for a proven technology for producing nitrogen or oxygen. INMATEC has been using the PSA technology in its machines and systems for many years. The nitrogen or oxygen is separated from the remaining air components and compressed.

The molecular sieve for nitrogen generation and oxygen generation essentially differ from each other.

Nitrogen is filtered from the compressed air with the help of activated carbon, while oxygen is produced with so-called zeolites. INMATEC ensures the highest possible quality of the respective filter materials here.

Not all molecular sieves are equal. Even within some manufacturers, differences exist, e.g. depending on the place of production, size and quality.

If you obtain your molecular sieve from INMATEC, you have the greatest assurance that the most suitable model, appropriate for your INMATEC system, is being used.
