FRP Centrifugal Fan

  1、Pressure up to 7000Pa, suitable for a wide range of operating conditions. High efficiency and energy savings reduce operating costs.

  2. FRP construction provides corrosion resistance, high strength and safety.  Reinforced construction and low vibration. Computer stress and strain analysis improves structural strength. Impeller dynamic balancing meets JB/T9101 standard, grade G2.5 grade. Fan-unit vibration meets JB/T8689 standard, grade 4.5mm/s requirements or better, substantially reducing vibration-related shutdown risks and improving workplace safety.

3. Durable construction supports a long service life. FRPThe one-piece impeller has rigidity and yield strength comparable to steel. The casing is molded from Vinglester premium resin with a UV-resistant gelcoat for extended service life.

4. Oil-bath pedestal bearings and a sealed oil reservoir protect bearings and shafts from acidic and alkaline gases, extending service life and reducing failures.

     1. Fan casing: Showa 901 vinyl ester resin, Taishan/Jushi fiberglass and a marine-grade corrosion- and UV-resistant coating；
