Oil-free air compressor, as the name implies, is an air compressor that does not require the addition or generation of lubricating oil during the compression process. Its working principle is mainly based on the following aspects:

​The principle of centrifugal air compressor is to compress gas by centrifugal force.

Oil-free scroll air compressor is a special air compressor that uses the scroll compressor refrigeration principle to compress gas.

In recent years, as industrial gas costs continue to fluctuate, more and more manufacturing plants, laboratories and medical facilities are switching from traditional cylinder supply to on‑site gas generation. Nitrogen and oxygen generators, especially those based on PSA (pressure swing adsorption) and membrane separation technologies, have become invisible but essential pillars of production lines.
