1, Atlas Copco Atlas, Copco (referred to as AC)?
AC is a multinational group, headquartered in Sweden, air compressor manufacturers are just one of its subordinate groups. As a result of years of constant acquisitions, AC is able to produce almost every form of air compressor and is quite renowned. It is estimated to have the highest share in the world...?
AC mainly produces oil screw air compressors, there are a number of factories around the world, there is also a factory in Wuxi, China.
AC mainly relies on its subsidiaries to sell its products in China, with branches in Beijing, Shanghai, Guangzhou and other important cities.
The biggest advantage of AC is its popularity, and it is able to adopt flexible pricing for important projects.
2. Ingersoll-Rand (hereinafter referred to as IR)?
IR is also a multinational group, its headquarters is located in the United States, the air compressor manufacturer is only one of its subordinate groups. IR can also produce various forms of air compressors, a wide range of products, and high visibility. IR in the global market share is second only to the AC or not similar to it.
IR was one of the first companies to enter into a joint venture to produce screw machines in China, founded in Shanghai in 1987. before 1995, IR Shanghai was doing very well in terms of production and sales. Customers in the market were waiting to buy screw machines, and at this time only IR was producing screw machines.?
IR sells mainly through its branch offices, which are located in all major cities in China, such as Beijing, Shenyang, Qingdao, Wuhan, Sanxia, Guangzhou and Shanghai. In other regions, IR sells through distribution agents.
IR's current advantage remains its popularity, and its disadvantage lies in the fact that it has two sets of sales systems: one for Far East IR and the other for Shanghai IR. It is difficult to unify the perceptions of the members of the two sets of organizations, which has weakened its overall competitiveness to a certain extent. As a result, IR's screw machines are still selling well within China at the moment.
3, Compair/Demag Compair/Demag (hereinafter referred to as Compair)?
Compair is a British company, mainly known in the industry for the production of sliding vane air compressors (≤ 50 HP). There is no information on its profitability. In recent years, Compair has acquired the screw compressor division of Demag in Germany and Leroi Compressors in the US to become a global compressor company.
Compair's strengths are: a, the sliding vane machine is cheaper; b, Demag's screw machine also has a price advantage; c, a complete range of products; d, set up factories in China.
4, Sullair Sulli?
Sullair is a large U.S. aviation (military) companies under the company, the production of air compressor history is not long, mainly screw machines. sullair has branches around the world, in the United States, it is second only to IR air compressor company.
Sullair mainly sells through agents; before 1999, its agents were mainly Tang Sheng from Taiwan and Ke Ming from Guangzhou. Recently, the number of its agents has increased significantly. Currently, Sullair has a considerable track record in certain industries, such as textiles and automotive...?
Sullair's main products are oiled screw type and mobile type, and its oiled screw type has a great price competitiveness at the time of high horsepower type (300HP). Its mobile type is said to be mainly localized in recent years, a move that will increase its market share.
5, Fusheng Fusheng?
F, S, is a joint venture with three domestic factories in China: Zhongshan, Shanghai and Beijing. F, S, opened the Chinese market through its good quality small piston machines, with dealers all over the country.?
F, S, has been a well known air compressor manufacturer in China domestic, but its screw machine is still the representative of low-grade machine.?
Extended information:
An air compressor is a device used to compress gases. An air compressor is similar in construction to a water pump. Most air compressors are reciprocating piston, rotary vane or rotary screw. Centrifugal compressors are very large applications.
The compressor is driven directly by an electric motor, which produces a rotary motion of the crankshaft, which drives a connecting rod to produce reciprocating motion of the piston, causing the cylinder volume to change. As a result of the change in pressure in the cylinder, through the inlet valve so that the air through the air filter (muffler) into the cylinder, in the compression stroke.
Because of the reduction of cylinder volume, the compressed air through the role of the exhaust valve, through the exhaust pipe, check valve (check valve) into the tank, when the exhaust pressure reaches the rated pressure of 0.7MPa by the pressure switch to control and automatic shutdown. When the pressure of the gas storage tank drops to 0.5-0.6MPa, the pressure switch is automatically connected to start.
