BONFIGLIOLI Motor& gear box with lengthened large diameter connecting shaft. Motor equipped with double fluorine rubber oil seal to ensure reliability of drive system. Fan equipped with start up delay function which can reduce the Strain on the motor and Extend life.
The integrated chasis system is made using high precision cutting technology. The high precision cutting ensures the consistency of chassis, and stability of each fan.
Designed using advanced fluid simulation software CFD and wind tunnel testing. High quality aluminum magnesium alloy blade with a life span of more than 20 years. Tough, Corrosion Resistant and easy to clean because of the anti-oxidant treatment.
Danfoss VFD, frequency converter with the functions of over current, under voltage, phase lack, overload and overheat protection. Control panel manufactured with the best quality components. Frequency convertor with protection Against voltage fluctuations, power fluctuations and heating protection.
• Secure chain connection to prevent fan leaf damage
• Unique Auto Stop Function
• Our patented HUB reduces axial forces on the gear box, reduces friction between gears, reduces oil spill. Thus extending the LIFE of the gear box.
• Double outer bearing bears the blade weight, protects the gear box and improves motor use. Anti falling security baffle prevents accidental falling.
• Danfoss vector inverter controller, capable of bearing high carrier frequency to reduce motor zing, improve the control pulse signal quality & built in filter to reduce interference.
• Fan is fastened using 8mm steel wire ropes for stability & safety
• 5 Years replacement warranty
• The double outer bearing extends the service life of the motor by extending the guide distance and avoiding the axial force acted on the reduction box, as well as preventing the oil leakage.
• Completely resolves the risk of inertial impact caused by the abrupt power cuts while the fan is rotating
