Poultry Farm Ventilation Exhaust Fan

Product Application Widely applied in a range of livestock Husbandry Farms, Greenhouses, Industrial Buildings for the Ventilation and Air Cooling
Main PartsDrop Hammer/Weight Balance Swing-open DeviceBodyNylon PA66
Fixed partscopper rivets
Make sure the shutters are completely open at the least air resistance against the biggest air flow, and closed with tight blocking for the light and wind.
As the first adopted with excellent nylon PA66, ensure the long service life.The linked part are fixed with copper rivets, which are wear-resistant, anti-rust, flexible, and friction coefficient's reduced.
Fan BladeSurface Fineness DegreeBA
Thickness1.2mmMaterial OptionsStainless Steel/ Hot-galvanised Sheet/Al-Alloy/FRPFan blade is made of Krupp stainless steel by punch forming, which makes the blades off-dust with aesthetic appearance, meanwhile the constant big air volume with little possibility of distortion or broken.They are also adjusted by intelligent tester, making the dynamic balance is controlled within 1g, the international standard, ensured the smooth running, lower vibration, less noise, increased stability.

OriginalDomestic / Imported
Light weighted , high corrosion resistance. Specialized 3-reinforced-rib design , together with the grit-blasting on the surface , besides the aesthetic appearance, the internal force is eliminated, improved the intensity and stability, genders no broken possibility.BeltBrand/OriginalDomestic or Japanese Mitsuboshi
Either brand can ensure the long service life , and maintanance-free. Our domestic B type, instead of A type in most of other factories, has 3 times longer service life.
Bearings
Brand/OriginalDomestic/FranceImported double-row bearings with waterproof design, high intensity , low noise, long service life and maintanance-free.
Shutter Frame InfoShutter/FrameMaterial OptionsHot-galvanised/ Stainless-Steel/Al-Alloy
Alternatives for hot-galvanised steel sheet (zinc thickness at 180g/m2 or 275g/m2), or stainless steel (304/430), both efficiently improved the anti-corrosion capacity. Size can be customised.
MotorBrandDomestic Laoyite/Simons
Protection DegreeIP55
Insulation DegreeF
Also can install Phase-loss protection device , for the notification of fault conditions and provide control contacts to turn off motors before damage occurs.Custom-made for the Voltage , Frequency as requested.
Shutter ClipsPlate-type shutter sealing clips make installation intenser , and the friction coefficient between fixed clips and rotational arm is much smaller than the original model which used the direct friction with plate. Hence this improved design make the opening&closing more flexible.Recessed HandlesEasy carrying, assembling and disassembling.Rational design without injuring hands, plus elegant look.
