3.Product Feature And Application

centrifugal exhaust fan is the product with the least damage to the customer's installation environment among the ventilation and cooling equipment products. It basically does not occupy the customer's space and does not need to install air ducts. It is usually installed on windows, walls, or roofs.


4.Product Details

Our centrifugal exhaust fan blade is special designed for the biggest efficiency which made of Krupp stainless steel by punch forming. Large air volume, no deformation, no broken, no dust, attractive and durable. Thickness 1.2mm, surface finish BA grade

Centrifugal system open the shutters at complete 90 degree to ensure the lowest air resistance and biggest air volume. When close, the sealing can efficiently block light and wind into the poultry farm house. As the first one adopt high quality nylon PA66 to ensure the long service life. The fasteners of centrifugal system all are copper rivets, wear-resisting and no rust, flexible. Guide rod is made of 304 stainless steel, ensure the high strength, no rust, reduce friction

Frame adopts Hot Galvanized sheet with zinc thickness of 275g/m², which extremely improve its anti-corrosion performance. Shutter fixed parts are made of high quality nylon which ensure long service life, open flexibly.Shutters are made of galvanized sheet with thickness of 0.8mm and 1.5mm, ensure shutters no deformation, running stable

Belts are Japanese Mitsuboshi brand, ensure the long service life, maintenance free. From 2010 the first adopt Type B belt which 3 times longer service life instead of type A

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

Fan belt pulley and flange are made of high strength aluminum-magnesium alloy by die-casting. Light weight, lower vibration. Blast-sanding treatment for attractive appearance, eliminate internal stress to improve its own rigidity and stability

Motor plate fixed nuts, first change round type to hexagon type. And with stainless steel washer, more firmly, never loosen

Fan side frame with plastic handle, easy to carry, convenient to load, reasonable design without injuring hands, beautiful appearanc

Linking parts are made of aluminum alloy,light weight,no deformation,added with wear-resistant shaft sleeve.Reducing friction to ensure the shutters open flexibly.The spring is made of 304 stainless steel,long service life,no deformation,no rust

Standard parts especially the washer as fastener parts are made of stainless steel, no rust, beautiful appearance

Fan bearing adopts imported double-row bearing with special waterproof design. High strength, low noise, free maintenance and long service life

The fasteners fixed on both ends of blade support are changed from traditional iron plates to aluminum magnesium alloy base, traditional welding connection to plug-in connection which has greatly reduced the friction coefficient, fixed more firmly, avoided rust and improved the appearance

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 for option

Hot-dip galvanized blade support and safe net ensure never rust

Complete new CNC production line improved fan quality up to top grade, aesthetic appearance


5. Product Qualification

Our centrifugal exhaust fan completely change to numerical control flow production, accurately grasp the product quality, and reach the high level of the international industry
