The top ten centrifugal air compressor brands are:

1. Atlas Copco (AC)

A multinational group headquartered in Sweden. The air compressor manufacturer is just a group under it. Due to years of continuous acquisitions, AC can produce almost all forms of air compressors and is quite famous. The first screw machine manufacturer with the largest strength and widest range of products. Oil-free machines and centrifuges are unmatched and have a large market share.

2. Ingersoll Rand (IR)

The earliest company to jointly produce screw machines in China was established in Shanghai in 1987. It started out as a manufacturer of construction machinery and refrigeration machines, and its market share is second only to Atlas. IR's most profitable product in China is centrifugal air compressors. Another profitable product is mobile air compressors, which are widely used in China.

3. Sullair, USA

A subsidiary of a large American aviation (military) company, the machines are certainly good. The main products are oil-filled screw type and mobile type. The mobile type has been mainly domestically produced in recent years, which will increase its market share. Sullair mainly sells through agents. Recently, the number of its agents has greatly increased, and it has considerable performance in the textile, automobile and other industries. The main advantage is that it already has a factory in China, and its high-horsepower products are relatively cheap. The product operates reliably and has a long life.

4. Kaiser

Germany’s largest air compressor manufacturer has strong production capacity and enjoys a high reputation in Europe. There are no factories in the country. It has set up a branch in Shanghai, China, and has an agent in Shenzhen, but has not yet established a sales network across the country. The advantage is that it is very famous in Europe and its price is competitive. The disadvantages are that it does not produce oil-free products, the network is not perfect, and the awareness of innovation is not strong.

5. CompAir/Demag (Compair)

A British company, mainly famous in the industry for the production of sliding vane air compressors (≤50HP). In recent years, Compair has successively acquired the screw air compressor department of Demag in Germany and Leroi Air Compressor Company in the United States to become a global air compressor company. A factory was established in Shanghai in 1993, but its nationwide sales network in China has not yet been established, so it does not have a great impact.

6. Quincy, USA

Since 1920, it has been committed to the compressed air technology industry, specializing in manufacturing and selling the highest quality air compressors and vacuum pumps. Products are widely used in global manufacturing, medical and climate control systems, and any industry that requires the use of safe and reliable gas sources. The main engine rotor is independently designed and manufactured by Quincy Company. It adopts an extra-large diameter rotor, and the machine has high reliability and durability.

7. Japan's Kobelco

It started at the beginning of the last century and has a long history of nearly a hundred years. In 1915, it produced Japan's first high-pressure reciprocating compressor, and in 1956, it successfully launched Japan's first oil-free screw air compressor on the market. In 1966, it began to produce centrifugal compressors and has since become one of the few comprehensive compressor manufacturers in the world that can independently produce piston, screw, centrifugal process compressors and air compressors.

8. Fusheng

The joint venture has three factories in China: Zhongshan, Shanghai, and Beijing. It is already a well-known air compressor manufacturer in China. It has opened up the Chinese market through its small piston machines with good quality, and has dealers all over the country, but its screw machines are still the representative of low-end machines. The biggest advantage is that it is cheap and well-known. The disadvantage is that the quality is poor, and the high-horsepower model has a high failure rate.

9. Liu Erkong

A joint-stock company restructured from Liuzhou Second Air Compressor Factory, it is a manufacturer of gas compressors, air drying and purification equipment and plastic molding machinery in my country. key key enterprises. Who passed the ISO9001 quality system in 1996. The products have won the title of National Quality Silver Award and Ministry of Quality Products for many times. It now has 6 categories, 16 series, and 119 varieties of products.

10. Shanghai Oriental

Founded in 1921, it has nearly 90 years of professional experience in manufacturing compressors and a group of high-quality management talents and experienced compressor technical experts. .

Extended information:

The centrifugal air compressor is mainly composed of two parts: the rotor and the stator. The rotor includes an impeller and a shaft. There are blades on the impeller, as well as a balance plate and part of the shaft seal. The main body of the stator is the casing (cylinder), and the stator is also equipped with a diffuser, a bend, a return flow device, an air inlet pipe, an exhaust pipe and some shaft seals. The working principle of the centrifugal compressor is that when the impeller rotates at high speed, the gas rotates with it. Under the action of centrifugal force, the gas is thrown into the diffuser behind, and a vacuum zone is formed at the impeller. At this time, the fresh gas from the outside world Enter the impeller. The impeller rotates continuously, and the gas is continuously sucked in and thrown out, thereby maintaining a continuous flow of gas.
