Big Fan

1.Processed by adopting advanced equipments and technology and quality materials, the frame has strong corrosion resistivity. 2.Unique high strength hub has better strength,tenacity & longer life than the general nylon hub. 3.With automatic adjuster, the belt need not manually adjust within the belt life period. 4.New type blade, subjected to the tests of dynamic balance and static balance, ensures generation of a lot of air volume at the reasonable blade angle and a good noise control. 5.National patent aluminum alloy shutters with particular pneumatic opening & shutting mechanism, adopting the inclined belt to drive, ensure the shutters can open and shut fully to protect against wind & rain and dust. 6.Fan is subject to eight strict quality testing procedures——noise, vibration, dynamic balance, static balance, rotary concentric performance, blade rotating speed, overall efficiency test prior to shipment. 7.Can be combined with cooling pads to form vertical ventilating and cooling system, which is the most inexpensive and effective cooling measure in summer. 8.The cooling fans we produce are widely used in industrial workshops, civil fields & agricultural fields.. Our products enjoy high reputation at home & abroad and sell well in China, Southeastern Asia, Africa, Mid East, Europe and USA, etc. Fan technical parameter: Model Blade diameter:1000mm Blade rotating speed:600r/min Motor rotating speed:1400r/min Air volume:35000m3/h Full Pressure:70Pa Noise:≤70decibel Input Power: 750W Rated Voltage: 380V Height:1100mm Width:1100mm Thickness:400mm
