Detailed Introduction:
1.Fan blade is made of Krupp 430 stainless steel by punch forming, no dust, attractive and durable. Special blades shape design ensure large air volume, no deformation, no broken, keep air volume same all the way. Thickness 1.2mm, surface finish BA grade.
2. Fan belt pulley is made of high strength aluminum-magnesium alloy by die-casting which reduces the weight of blade impeller complete, high corrosion resistance. Special three reinforced ribs pulley design. Blast-sanding treatment for attractive appearance, eliminate internal stress to improve its own rigidity and stability, never broken.
3. Both China famous motor and Siemens motor are available. Motor voltage and frequency can be customized. Chinese famous motor OEM by special design for fan, the first put in the phase lack protection device which would power off when shortage of electricity. Motor protection grade IP55, insulation class F grade.
4. Fan bearing adopts imported double-row bearing with special waterproof design, water can’t enter. High strength, lower noise, maintenance free and long service life.
5. Belts are Japanese Mitsubishi brand, ensure the long service life, maintenance free.
6. Using high strength nylon swung drop hammer opening device to ensue the shutters opening and closing flexibly.
7. Fan blades are adjusted by intelligent dynamic-balance tester, each blade tolerance weight controlled within 1g. Ensure the fan smooth running, lower vibration, less noise, increase stability. Blade material have stainless steel, galvanized sheet, aluminum alloy, FRP for option.
8. Hot-dip galvanized blade support and safe net ensure never rust.
9. Complete new CNC production line improved fan quality up to top grade, aesthetic appearance.
