VPSA oxygen generator is an oxygen manufacturing equipment widely used in industrial, medical, household and other fields, and its service life is an important factor to consider. The length of service life directly affects the efficiency and safety performance of equipment, and also has an impact on the maintenance cost of the equipment.

A box type nitrogen generator is a device that separates oxygen from nitrogen in the air, in order to obtain high-purity nitrogen separately. Box type nitrogen generators are widely used in many industries, including metallurgy, chemical engineering, electronics, pharmaceuticals, beverages, healthcare, gas welding, and so on.

Centrifugal air compressor is a device that can quickly compress air into high-pressure air and is widely used in modern industrial production. Its working principle is to compress gas through centrifugal force, hence it is called a "centrifugal" air compressor

Fixed screw compressors are one of the common types of compressors in industrial production, with advantages such as small size, high compression efficiency, and stable operation. They are widely used in industries such as metallurgy, chemical engineering, and pharmaceuticals. However, due to the complexity of the technology and process involved in fixed screw compressors

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.

A fixed screw compressor is a mechanical device that compresses gas into high pressure. Its main working principle is to compress the gas through two spiral rotating impellers and push it towards the outlet. Screw compressors have some important working principles
