Corrosion-resistant Centrifugal Fan

 1. The fan consists of FRP parts (impeller, volute casing and inlet cone), bearing housing, steel frame assembly and motor drive.

 a. Impeller: blades, backplate and front shroud made of vinyl ester FRP;  

 b. Casing: housing and outlet made of vinyl ester FRP.  

 c. Inlet and volute: integral FRP construction at the fan side, with a curved axial profile for smooth entry into the impeller and low losses.

 d. Bearing housing: integral oil-bath housing, precisely aligned drive and oil-bath cooling

 e. Motor: horizontal motor with a rain cover.

2、Corrosion-resistant Centrifugal FanHigh aerodynamic efficiency, low noise and strong corrosion resistance.
