Top margin FRP centrifugal fan with low noise can be widely used: corrosive acid gas pumping exhaust gas treatment purification, sewage odor, etc., containing corrosive gas environments. Top margin low noise FRP centrifugal fan Features: a wide range, for a variety of operating conditions of energy efficient (saving), you create a profit, cost savings, top margin FRP centrifugal fan with low noise characteristics: A. Pre-injection shell with screws France to reduce the error repair, storage location contact function B. Bell and the shell of the side entrance to the axis of the plane to reduce leakage and bearing installation C. axis protection, increased security (domestic fan does not) D. motor to slide design is easy to adjust and transform horsepower E: impeller using the most advanced design techniques triples, and for the pure glass steel production, (domestic over many fans on the use of steel impeller 3000PA coated fiberglass production, easy delamination) F: impeller base increase back ribs, can enhance the strength of the impeller, shaft seal can also increase the suction fan section, truly zero leakage. (Domestic fan does not)
