  The fan blade is stainless steel , big air volume, without distortion, no broken, attractive and durable.(  
    adopting aluminum fan blade in the past, which had some problems caused after long time working of metal in the factory cooling, for example broken and air volume decreasing).  
  Adopts automatic belt tensioner which can adjust up and tight so that the belt can’t loose and drop .  
  The belt pulley adopts more stiffening rib and processed by sandblasting, become attractive, eliminate the  
    internal stress and increase own strength efficiently;  
  France imported axletree(bearings), high intensity, low noise, long service life.  
  Variety sizes of shape and install conveniently.Size of shape(blade): 620mm(24″)、780mm(30″)、  
    830mm(32″)、900mm(35″)、1000mm(39″)、1100mm(43″)、1220mm(48″)、1380mm(54″)、1530mm(60″)nine kinds.
