South China Low noise centrifugal fan shell with screws pre-injection method to reduce the error of repair, contact surface deposit in southern China targeting low noise centrifugal fan inlet bell and the shell of the plane to reduce leakage axis and the axis of the bearing installation of protection, increased security (domestic wind turbine does not) motor to slide design for easy adjustment and transformation horsepower rotor uses the most advanced three-way design techniques, and for pure glass steel production, (many fans 3000PA more on domestic carbon steel impeller coated fiberglass production, easy delamination .) impeller base increased back ribs, can enhance the strength of the impeller, shaft seal can also increase the portion of the suction fan, truly zero leakage. (Domestic wind turbine does not) company mainly produces frp fan, FRP fan, pp fan, pvc fan, fan anti-corrosion, FRP centrifugal fans, centrifugal fans, plastic fans, laboratory fan, energy saving fan, acid fan, General Fan, deodorant fan, Boiler Fan, boiler blower, high pressure blower, dust blower, high pressure air, professional fan, heat fan, stainless steel fan, sewage deodorant fans and fire resistant to high corrosion pipeline, air and water treatment equipment and other products according to ASTM Pre-Testing Association ASTMD4167 and AMCA210 strictly regulate the design, we have passed the ISO9001: 2000 quality system certification. High performance, high efficiency, low vibration, low noise and so become an international semiconductor, precision electronics, chemicals, sewage treatment, metal processing enterprises exhaust system equipment, with our abundant human capital and continuous innovation, will be able to to safeguard the health of humans and eternal create a comfortable and peaceful environment.
