Definition: High pressure fan refers to the fan with air pressure of 30kPa~200KPa or compression ratio of e=1.3~3 under design conditions, which can also be called high pressure blower.

Composition: It is composed of motor, inlet and outlet air duct, impeller, bearing, casing and sealing ring.

Working principle: When the impeller rotates, due to the centrifugal force, the impeller impels the gas to move forward and outward, thus forming a series of spiral movements.

Classification: classified according to the direction of gas flow: centrifugal, axial, diagonal and cross flow.

Classified by the number of built-in impellers: single section fan, double section fan and three section fan.

Relevant experts believe that energy-saving fan products are not only reflected in product design, but also in fan operation. The high-pressure fan is made of aluminum alloy, which is light in weight; The motor is a fully closed external sector aluminum frame motor, which can be used for a long time with the special axis design; The unique blade design and air volume regulating damper endow the high-pressure fan with the characteristics of large air volume, low noise and easy operation. It is a product with low energy consumption and high reliability, and is suitable for infrastructure construction, environmental protection industry, automobile industry, electroplating industry, aquaculture industry, industrial dust collection and other fields.

It is also worth noting that air suction and air supply are the major features of high-pressure fans that distinguish them from other fans. This is impossible for other ventilation equipment. The reason why the high-pressure fan can save energy is that it does not require much lubricating oil during operation, but only a small amount. One machine can be used for two purposes. The high-pressure fan of Ouruidi Environmental Protection can be used in dozens of fields, such as engraving machine, welding waste gas absorption, industrial dust collection, vacuum dehydration, livestock manure fermentation aeration, incinerator grate waste, etc.

The key to high pressure fan is "high pressure". According to the data, compared with other fans, the pressure is relatively high, and its pressure is dozens of times more than that of centrifugal fans, which is also a major advantage of high-pressure fans over other fan products. Take the environmental protection industry as an example, high-pressure fans have been widely used in water treatment, such as sewage aeration, to meet the oxygen content required by aerobic microorganisms in activated sludge and the conditions for full contact and mixing of sewage and activated sludge, so as to degrade various organic substances in water to achieve the purpose of sewage purification, and also play a role in mixing.
