The fan blade surface uses PTT corrosion preventing material spray
coating processing, the characteristic is the dust cannot stick on
the surface, guaranteed that 8 years do not go bad. Domestic own
technology
A、The outer edge uses the advanced automatic processing craft, the
precision is extremely high; The especially thick galvanization
level, the corrosion resistivity is greatly strengthened B、 High strength aluminum alloy casting wheel hub, new distortion
ramming formation fan blade; The reasonable blade section angle,
may achieve the maximum air flow; The high accuracy microcomputer
auxiliary manufacture system may cause the air blower display
biggest potency C、five strict quality detection procedure; Noise examination,
vibration examination, rotation concentric performance examination,
wind leaf rotational speed examination, complete machine efficiency
examination; High performance 380V NBC special-purpose electrical
machinery; cad optimization design
D、Uses the stainless steel fan blade, does not distort, does not
break artisticly, durable, improves the aluminum alloy fan blade
break question thoroughly E、Uses the leather belt to rise automatically the tight
installment, causes the leather belt not loose belt, to fall the
belt, to cut the air blower failure rate
