PSA nitrogen generator is a type of nitrogen production equipment widely used in many industries. It uses molecular sieve technology to separate air into oxygen and nitrogen. Although this device is convenient to use, there are still some safety risks during use.

An oxygen concentrator is a device used to separate and purify oxygen from the air before outputting pure oxygen. Its working principle is to separate oxygen from other gases such as nitrogen in the air through physical and chemical means, and then output the separated pure oxygen through the output port.
