2.FRP process, is often said to be FRP process, is generally the common raw material of centrifugal fans. These raw materials have high quality properties that can withstand a wide range of acids and alkali salts. Fiberglass process centrifugal fans are used for various gas treatment in chemical plant processing and manufacturing industry.

3.Stainless steel plate is also a common important raw material of centrifugal fan, it is not a raw material, but also contains a variety of unique raw materials, including martensite, austenite, metallographic structure, duplex steel, etc.

4.Choose plastic as the key raw material, generally PP, but because the tensile strength is lower than the glass fiber reinforced plastic process, so the scope of use is small, rarely used, but because of its characteristics, can be used in the fan.
