In 2018, China's air compressor market was mainly composed of piston type, screw type, centrifugal type, sliding vane and other air compressors, of which piston type accounted for the largest proportion, followed by screw type, centrifugal type, sliding vane, scroll type and so on.

In recent years, with the development of screw air compressor and centrifugal air compressor, the proportion of piston air compressor in the industry has decreased, but it still dominates the market.

”Compared with the piston air compressor, the screw air compressor has the advantages of low operation cost. From the whole life cycle of the machine, the investment recovery rate of the screw air compressor is 20% higher than that of the piston air compressor, and the energy-saving effect is obvious. Therefore, the screw air compressor begins to replace the piston air compressor step by step in many fields.

Especially under the energy-saving development trend of "low-carbon and environmental protection", the rapid development of domestic mining, metallurgy, electric power, electronics, machinery manufacturing, medicine, food, textile light industry and petrochemical industry will also accelerate the elimination of backward processes and high energy consuming equipment, promote the upgrading of compressor equipment from low added value to high added value, and bring further development opportunities for screw compressor industry.

During the "Eleventh Five Year Plan" period, China's screw machine has partially replaced the piston machine. It is expected that the replacement of screw machine to piston machine will continue, and the demand for piston machine will gradually decline. However, in view of the wider application fields and relatively low price of piston air compressor, its market demand will still maintain a certain level. The prospective industry research institute predicts that the market scale of screw air compressors in China will maintain an average annual growth rate of 15% from 2014 to 2018.

In recent years, although the proportion of piston air compressor in air compressor has decreased, it still occupies a major position. In 2008, the proportion of piston air compressors in air compressors accounted for 81.8%. Although the proportion has decreased in the past two years, it remains above 75% as a whole. In 2011, the market scale of piston air compressor in China was about 100.137 billion yuan. In 2012, the market scale of piston air compressor was about 108.039 billion yuan. According to the analysis report on production and marketing demand forecast, transformation and upgrading of China's air compressor industry from 2014 to 2018 issued by the prospective industry research institute, the market share of screw air compressors in western developed countries was about 80%, while that in Japan was 27% in 1976 and 85% in 1985. In the future, the replacement of piston compressors in China will continue to increase, but considering the replacement cost of equipment, this replacement process will take some time.

Centrifugal air compressor - because the centrifugal compressor is an oil-free compressor with good safety and health performance, it can be used in food, pharmaceutical, mining, air separation and other industries with high requirements for working environment.

At present, centrifugal air compressors are mainly used in steel, petrochemical, shipbuilding, electric power and automobile, and their demand can account for more than 70% of the total demand of centrifugal air compressors. At present, the steel, shipbuilding, electric power and automobile industries are in a downward trend. It is expected that the slowdown of downstream growth will slow down the growth of centrifugal compressor industry.

Scroll air compressor is the latest air compressor developed in recent years. Compared with traditional air compressors, it has a series of excellent technical properties, such as novel structure, small volume, light weight, low noise, long service life, stable and continuous gas transmission, simple operation and low maintenance cost. It is known as "maintenance free air compressor" and "new revolutionary air compressor" in the industry, It is an ideal model of air compressor below 50HP. At present, scroll compressor is still mainly used in the field of refrigeration.

In the past two years, affected by the economic downturn, the decline of air conditioning sales has led to the decline of turbine air compressor sales. However, in the future, with the improvement of economic situation and the improvement of residents' consumer confidence index, turbine air compressor can still maintain a certain market growth rate. The machinery industry is still the most important market for air compressors, accounting for 40% of the total sales. The demand of chemical industry, electric power and other industries is also growing rapidly. In the field of power, the sales volume of piston compressor is greater than that of other products. However, with the improvement of people's requirements for use environment, energy consumption and environmental protection, energy-saving air compressors such as screw and scroll will have a large market space in the future.

At the Third Plenary Session of the 18th CPC Central Committee, the issue of energy conservation and environmental protection was also included in the conference on building an "upgraded version" of China's economy. According to the analysis report on production and marketing demand forecast, transformation and upgrading of China's air compressor industry from 2014 to 2020 by the forward looking Industry Research Institute, relying on the national policy of energy conservation and emission reduction, energy-saving products in the air compressor industry will become winners in the downturn in the future. Enterprises should strengthen the research and development of products, constantly produce more advantageous products and enhance the core competitiveness of enterprises.

According to the data, the market scale of China's air compressor industry has increased by more than 8%, and the growth rate from 2010 to 2017 even exceeded 28%. The market scale has expanded rapidly. However, in such a huge market, foreign-funded enterprises controlled most of the market for a long time. In 2009, there were nearly 400 production enterprises in China's air compressor industry, of which the number of domestic enterprises was nearly 90%, and the total sales revenue was about 6 billion yuan, accounting for 40% of the whole industry; The number of foreign-funded enterprises is close to 10%, and the total sales revenue is about 9 billion yuan, accounting for 60% of the whole industry.

Since 2017, the domestic economic situation has remained complex, the industry demand in the downstream application field of air compressor, which is closely related to macro-economy and fixed asset investment, is still low, the market demand has not come out of the weak situation, and the sales performance of most enterprises in the industry has declined. Relevant people believe that there is still downward pressure on China's macro-economy in 2014, and the possibility of rapid economic recovery is small. As an investment product, the industry as a whole may continue to be depressed.

With the continuous progress of society and the development of science, energy conservation has increasingly become a topic of concern. In recent years, the country has continuously increased the promotion of energy-saving products. As a product applied in many fields, the introduction of energy-saving products of air compressor is of great significance to China's energy-saving cause.

Under the energy-saving development trend of "low carbon and environmental protection", the rapid development of domestic mining, metallurgy, electric power, electronics, machinery manufacturing, medicine, food, textile light industry and petrochemical industry will also accelerate the elimination of backward processes and high energy consuming equipment, and promote the upgrading of compressor equipment from low added value to high added value, so as to bring further development opportunities for screw compressor industry.
