In pharmaceutical industry, nitrogen generator is mainly used for nitrogen filling, packaging, transportation and protection of pharmaceutical raw materials and drugs; Nitrogen filling of Western medicine injection, nitrogen filling of storage tank and container, pneumatic conveying of gas source, etc. According to the international standard GMP of pharmaceutical industry, the purity of helium making machine must be high. Moreover, different from the common nitrogen production equipment in other fields, the medical nitrogen production equipment must be made of stainless steel, and the nitrogen outlet also needs to be equipped with sterilization and filtration device. It is reported that with the improvement of GMP standards, many pharmaceutical enterprises are also making efforts in this regard. There are many pharmaceutical high-purity nitrogen generators that meet the standards, mainly composed of three systems: compressed air after-treatment system, PSA pressure swing adsorption system and precision filtration and sterilization system.

According to people in the industry, the pharmaceutical high purity nitrogen generator adopts the latest PSA nitrogen generator process in the world, adopts all stainless steel high grinding treatment and unique adsorber structure design, so as to ensure the production of high purity nitrogen (higher than the international anaerobic requirements), with nitrogen purity of 99.999%, no heat source and aseptic falling, meeting the CP production requirements of the international pharmaceutical industry. At the same time, the use of automatic control and monitoring system, so that the equipment to achieve automatic operation, unattended, widely used in the pharmaceutical industry. Only the standard equipment can ensure the safety of pharmaceutical production, nitrogen generator equipment enterprises can operate in good faith, work hard on the improvement of equipment performance and technology, and better serve the pharmaceutical industry.
