Features:
　　1、It adopts the temperature control technology ---- using pancake coil with N, total number of the turns unchanged ---- to increase the quantity of the coil to increase air passage and exposure of the coil to the air to improve the cooling effect.
　　2、It applies the low-noise axial aerofoil fan, with strong wind pressure, large blast volume and satisfactory cooling effect.
　　3、The control gear employs the interlocking mechanism. The magnetic separator excitation cuts off the power and gives alarm immediately the blower stops.

Applications：
　　It can be applied to remove ferromagnetic matter from dry coal, coke, limestone and detritus.
