In 1935, Germany first adopted axial flow isobaric fans for boiler ventilation and induced draft; In 1948, Denmark developed an axial flow fan with adjustable moving blades for operation; Rotary axial flow fans, radial acceleration axial flow fans, diagonal flow fans, and cross flow fans have also been developed.
With the progress and development of the times, people are no longer satisfied with the pressure and air volume requirements of centrifugal air pumps, and the noise of centrifugal air pumps has become an increasingly headache within factories. So, Japan first introduced fully enclosed flow measuring fans, which are now known as high-pressure fans (vortex vacuum pumps). This fan, with its compact appearance and noise, met the demand for high-pressure fans in society at that time. Later on, this fan was upgraded successively and developed into high-pressure fans with single-stage, two-stage, and three-stage impellers. The maximum pressure of the high-pressure fan was once refreshed to 230kpa. It is widely used in industry and agriculture, covering infrastructure construction, environmental protection industries, automotive industry, electroplating industry, aquaculture industry, industrial dust collection, packaging machinery industry, printing machinery industry, plastic industry, chemical industry, food, pharmaceutical industry, medical industry, electrical and electronic industry, light industry and textile industry, shipbuilding and railway engineering, and so on.

The vortex fan has dual functions of blowing and suction, which can be used for both suction and blowing; Running with little or no oil, the output air is clean; Compared to centrifugal fans and medium pressure fans, their pressure is much higher, often more than ten times that of centrifugal fans. Currently, the maximum pressure is up to 101KPA; The pump body is die cast as a whole and uses shockproof mounting feet, so its requirements for the installation foundation are also very low. It can even operate normally without fixing the feet, which is very convenient and saves installation costs and installation cycles.
