Centrifugal Push-Pull Exhaust Fan (Double Rotational Hammer)

Product Specification

Centrifugal Push-Pull Exhaust Fan (Double Rotational Hammer)

● Blade: 6 fan baldes is special designed for the biggest efficiency which made of Krupp 430 stainless steel by punching forming. Large air volume, no deformation, no broken, no dust, attractive and durable. Thickness 1.2mm, surface finish BA grade. Through intelligent dynamic-balance tester, ensure the fan smooth running, lower vibration, less noise, increase stability.

● Centrifugal System: 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: Frame adopts Hot Galvanized sheet with zinc thickness of 275g/m², which extremely improve its anti-corrosion performance.

● Shutters: Shutters are made of galvanized sheet with thickness of 0.8mm and 1.5mm, ensure shutters no deformation, running stable. Shutter fixed parts are made of high quality nylon which ensure long service life, open flexibly.

● Defend Net: Hot-dip galvanized anti-rust processing.

● Motor: Chinese famous motors, Siemens motors and ABB motors for option; Motor voltage,frequency and phase can be customized. Motor protection class is IP55, Insulation class is F.

● Belt Pulley: Fan belt pulley is made of high strength aluminum-magnesium alloy by die-casting which reduces the weight of propeller, high corrosion resistance. Special three reinforced ribs pulley design. Sand blasting treatment for attractive appearance, eliminate internal stress to improve its own rigidity and stability, never broken.

● Belts: China faand Sanlux belt, Japan Mitsubishi belt, Korea Dongil belt for option, long-term use of deformation.

● Bearing: Fan bearing adopts imported doublerow bearing with special waterproof design, water can’t enter. High strength, lower noise, maintenance free and long service life.

● 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 appearance.

● 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.

● 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.
