Sotop Axial Fan Serie：

Featured of excellent heat dissipation, is effective in reducing the bearing temperature, thus prolong the service life of the blower.  Considerable  rise in temperature is inevitable in the inner part of the blower during work.  If the bearings are exposed in high temperature for very long time and the heat fails to be sent out, the service life of bearing will be in great risks, and the efficiency of the working machine will be influenced.  In order to reduce the negative effects brought by the rising  temperature, introducing a cooling device is critical and necessary.  

Oxidation-resistant metal fan blade：

What makes Sotop Axial Fan Serie standing out is the oxidation-resistant metal fan blade, which performs much better in heat dissipation and much longer life span than usual plastic counterpart.  The majority of existing blowers made of PBT or PC material are not capable of blocking the incoming electromagnetic waves.  With the help of Sotop oxidation-resistant metal fan blade, the disturbances from electromagnetic waves are eliminated at the largest extent.  Assisted by the surface treatment technology, oxidation will not be happening on metal fan blade even long exposed in natural environment.
