1. Atlas Copco Atlas, Copco (AC for short)?

AC is a multinational group headquartered in Sweden, and the air compressor manufacturer is just one of its subsidiaries. group. Due to years of continuous acquisitions, AC can produce almost all forms of air compressors and is quite famous. It is estimated to have the highest share in the world. ?

AC mainly produces oil-filled screw air compressors. It has multiple factories around the world and also has a factory in Wuxi, China. ?

AC mainly relies on its branches for sales in China. AC has branches in important cities such as Beijing, Shanghai, and Guangzhou. AC's biggest advantage is its reputation and its ability to adopt flexible prices for important projects.

2. Ingersoll-Rand (hereinafter referred to as IR)?

IR is also a multinational group headquartered in the United States, and its air compressor manufacturing companies are only its subsidiaries A group. IR can also produce various forms of air compressors, with a rich product range and high reputation. IR's global market share is second only to or comparable to AC. ?

IR is the earliest company to jointly produce screw machines in China. It was established in Shanghai in 1987. Before 1995, the production and sales of Shanghai IR were very good. Customers in the market are waiting to buy screw machines, but at this time only IR produces screw machines. ?

IR is mainly sold through branches, with branches in major cities across the country, such as Beijing, Shenyang, Qingdao, Wuhan, Three Gorges, Guangzhou, Shanghai, etc. In other regions, IR sells through distribution agents.

IR’s current advantage is still its popularity, and its disadvantage is that it has two sales systems: one is Far East IR and the other is Shanghai IR. It is difficult to unify the concepts of the two sets of organizational members, which weakens their overall competitiveness to a certain extent. Therefore, the current sales status of IR's screw machines in China is still very good. ?

3. Compair/Demag Compair/Demag (hereinafter referred to as Compair)?

Compair is a British company that mainly produces sliding vane air compressors (≤ 50 HP) is well known in the industry. Currently, there is no information showing the source of its profits. 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.

Compair’s advantages are: a. The sliding vane machine is cheap; b. Demag’s screw machine also has a price advantage; c. The product range is complete; d. It has factories in China.

4. Sullair?

Sullair is a subsidiary company of a large aviation (military) enterprise in the United States. It has a short history of producing air compressors, mainly screw compressors. Sullair has branches around the world, and in the United States, it is the largest air compressor company after IR.

Sullair mainly sells through agents. Before 1999, its agents were mainly Tang Sheng from Taiwan and Keming from Guangzhou. Recently, the number of its agents has increased significantly. At present, Sullair has considerable performance in certain industries, such as textiles, automobiles, etc. ?

Sullair's main products are oil-screw type and mobile type. Its oil-screw type has great price competitiveness in the high-horsepower type (300HP). It is said that its mobile phones have been mainly domestically produced in recent years, a move that will increase its market share.

5. Fusheng?

F and S are joint ventures with three factories in China: Zhongshan, Shanghai and Beijing. F.S. has opened up the Chinese market through its high-quality small piston machines, with dealers all over the country. ?

F.S. is already a well-known air compressor manufacturer in China, but its screw compressor is still a representative of low-end compressors. ?

Extended information:

An air compressor is a device used to compress gas. Air compressors are constructed similarly to water pumps.

Most air compressors are reciprocating piston, rotating vane or rotating screw. Centrifugal compressors are very large applications.

The electric motor directly drives the compressor, causing the crankshaft to rotate, which drives the connecting rod to cause the piston to reciprocate, causing the cylinder volume to change. Due to the change in pressure within the cylinder, air passes through the air filter (muffler) through the intake valve and enters the cylinder during the compression stroke.

Due to the reduction in cylinder volume, the compressed air passes through the exhaust valve and enters the gas storage tank through the exhaust pipe and one-way valve (check valve). When the exhaust pressure reaches the rated pressure of 0.7MPa Automatic shutdown controlled by pressure switch. When the pressure of the gas tank drops to 0.5--0.6MPa, the pressure switch automatically connects and starts?
