Butterfly Cone Fan

Usually combined with the cooling pad for longitudinal ventilation. It can be applied to the poultry house, dairy farm, greenhouse and industrial use, etc.

● Double Door Opening Device: Using advanced front double door opening device, small wind resisitance, good sealing, high efficiency, lengthed cone design impove exhause power. Fan double doors closed with the rubber sealing which effectively avoid air backflow when start fans at different time. Greatly improve the operation efficiency by 15-20% compared with the same power fan.

● Cone: Adopt new design, plug type connection, not need many bolts and nuts for tightening as before, reducing intensity of labor and improving aesthetidurablec result of fan. Reasonable cone designing can get bigger airflow and lower noise.

● 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.

● Frame: Galvanized steel sheet, steel thickness 275g/m2, stamping forming, the bottom applies drainage outlest.

● 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.

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

● 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 famous brand 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.
