    Centrifugal fan, in our production is very wide range of applications. Centrifugal fans usually have the strongest structural design on site. They are made to be durable, tough and powerful enough to move large volumes of air by maximizing the pressure on almost any industrial fan configuration. In the type of centrifugal fan, there is a very popular centrifugal fan, that is, forward centrifugal fan. In the use of centrifugal fans, a very important issue is our fan noise reduction, and that we come today to introduce some noise reduction method of forward centrifugal fan.

    The forward centrifugal fan is composed of an outer rotor motor, a plastic front bending type or a metal front bending type impeller, a plastic or a metal volute, and has the advantages of compact structure, small size, light weight and convenient installation and use. It is widely used in automatic control devices, forced ventilation of electronic equipment and indoor pipe dust removal, exhaust, heat extraction, environmental protection, air purification and pollution control and other occasions.

    Rear centrifugal fan centrifugal rotor from the rotor, plastic / aluminum impeller combination of low temperature motor with ventilation and cooling of the unique advantages of cooling. Thus prolonging the reliability of fan life. The fan is curved after the impeller, with a compact structure, large air volume, high static pressure, small vibration, low noise, easy installation and so on. Mainly used for cleaning workbenches, purification units, ventilation ducts dust, air purification systems, environmental protection and pollution control and other refrigeration equipment supporting work.

    Since the forward velocity of the air flow is relatively large, the kinetic energy of the air flow is converted into pressure energy loss in the spiral chamber of the casing. Therefore, the static pressure head used to overcome the system resistance accounts for a very small proportion. However, the absolute velocity (C) of the backward-flowed blade to the gas flow is small, so the loss of the gas flow during the energy conversion is small. Therefore, the static pressure head used to overcome the system resistance accounts for a large proportion.
