As a Chinese oxygen machine manufacturer, we can provide a series of oxygen concentrators including 1~20L/min models with output pressure between 0.04 and 0.07Mpa, as well as 10-20L/min types with pressure between 0.14 and 0.4Mpa. Our products are widely applied in areas such as medical, home health care, industrial, aquaculture, pet, and stock farming. In addition to oxygen generators, we have also developed the ozone generator mainly used for water treatment and sterilization in laundries, hospitals, hotels and livestock breeding farms.

Longfian has strict administrative regulations and a capable R&D team. The control system and oxygen concentration monitoring system of our oxygen equipment are developed all by ourselves. Adopting self-developed components not only ensures the final product quality but also reduces production cost. Thus, our oxygen concentrators are competitive in price in the market.
