More About Us

Zhejiang Longfei Medical Instrument Co., Ltd. specializes in the development and production of oxygen generator for medical care, pressure swing adsorption oxygen generator for hospital centralized oxygen supply and hospital negative pressure suction system. It is the only leading enterprise in China with both household oxygen generator and hospital pressure swing adsorption oxygen generator. The company has been producing oxygen generator for 20 years, and has passed ISO13485 and ISO9001 certification.
Technology Overview
Our products adopt PSA technology.
At least two vessels with molecular sieves are used as adsorbers in our oxygen plant and oxygen generator.
When compressed air passes through one of the adsorbers, the molecular sieve will adsorb nitrogen.
This allows the remaining oxygen to pass through and leave the adsorber as a product gas.
Before the adsorber is saturated with nitrogen, the inlet flow switches to the second adsorber.
The first adsorber is now regenerated by desorbing nitrogen under reduced pressure and purging with oxygen.
Then repeat the whole cycle. Under normal operating conditions, the molecular sieve is completely regenerated and can be used indefinitely.
