Another is the capital and technology intensive, complex product structure, long manufacturing cycle, complete and systematic also strong, and operated under high pressure, high temperature and high speed conditions, and some even run in bad conditions, users of the class fans have different requirements. For turbine blowers and compressors and large fan, "Inflatable Air Blower" user is the main pursuit of high-quality, high reliability, smooth operation and long life cycle. Fan key to energy transmission and distribution systems, it is very critical part of building energy efficiency. According to the National Air Conditioning Equipment Quality Supervision and Inspection Center for many years a lot of fans in the fan test showed rated conditions are a problem, and therefore the need for strict product standards in accordance with the requirements of production and manufacturing wind turbines. Turbine compressors (including centrifugal compressors, axial compressor and axial - centrifugal compressor complex) is an important equipment of major projects complete sets of equipment, it plays an important role in the national economy. "Inflatable Air Blower" for both the performance requirements of the turbine compressor to high pressure, but also large flow. With large-scale complete sets of equipment, requiring higher and higher turbine compressor parameters. Such as blast furnace smelting equipment, large-scale coal chemical equipment, large-scale chemical fertilizer plant, a large ethylene plant, a large air separation plant, gas pipeline and oil field gas injection delivery device devices. From "Inflatable Air Blower" demand characteristics forecast for the use of a wide range of small and medium large fan, the product structure and manufacturing process is relatively simple, the cost is low, the user is the main pursuit of high efficiency, low noise, long life, and low price.
