exhaust fan for poultry house

Commoditydescription: Aircapacity:43170m3/h Size:1380×1380×450mm Noise:≤64dB Power:1.1kw Voltage:380V Electriccurrent:2.8A Weight:about89kg 1.The frame material is galvanized with advanced auto-machining techincs.Sheet thickness 180g/m2.The frame is pressed with flower pattern,which promotes the intension and toughness of the frame. 2.It uses Al-alloy rim,so it has light weight,high intension and good toughness. 3.Being imported from French Original,the bearing is of high intension and durable using-term without any noise. 4.Safety net with easy disaasembly is convenient for maintaining. 5.High precision system is assistanted by computers,which maximizes the effectiveness of the fan.The strict procedures that consist of airflow test,noise test,libration test,drive concentric test,blade RPM test,electric durrect test and whole mahine efficiency test,dynamic balance test,the thickness of the galvanized sheet test,the size of the spare parts test,etc.They assure the quality of the fan. 6.The guarantee period is one year,during which the easily damaged parts are offered free of charge. 7.Shutter is opened by this special automatic centrifugal open system. 8.Motor is specially used for high-performance fan,with updated design for automatic regulating device,the belt doesn’t need manual adjustment. Blades:The mirror face stainless steel blades are imported from German,the whole machine goes through balance test. Blade diameter:1270mm/910mm(36” ventilation fan).Blades are formed by stamping while the angle is suitable,which can make the biggest airflow as well as the smallest noise and not out of shape nor rupture during long using term. Additionally,each set of blades must be tested by balance system before sold,which will make sure the stable and smoothy work for the fan. Hot galvanized sheets.The thickness is 0.8mm and 1.5mm.It increases the intensity,life length and weight of whole machine.It improves the stability of the fan. The special and advanced centrifugal system assures the opening angle of the shutter so that air flow can be kept on the smooth high level.It is made of superior quality nylon and a litle fiberglass,also it is used rivet,which is made of cuprum so that they will antirust.Column-oriented is made of 304 stanless steel.It can ensure the shutter opens with the angle of 90 degree when the while machine runs on the rails. Demestic motor,Siemens,we will supply according to customer’s choice and suiting for local voltage and frequency. Installation hole of motor is six angles instead of the roundness,which can steady the motor better. Two kinds of belf pulley for selection:Aluminum,Cast Iron. It is used by aluminium magnesium alloy,light weight,high intensity.Flank is one-off injection moulded,with aluminium magnesium alloly,which is ne aerial material,ligh and high-strength with beautiul shape. The spring is made of high quality 304 stainless steel,it will be antirust and non-deformation during long term-using,which ensure to close the shutters in place. Being imported from Japan,the Mitsuboshi belt is of top performance and long using terms wihout any maintaining.
