Ventilation fan

Fan Components

1.Shatter: High strength hot-galvanized steel sheet, with a centrifugal system it will turn on automticly. Shtter will turn off and sel under the influence of gravity of springs when the ventilation equpments go off, which can effctively prevent and prohibit the ray outside from shining through and make the indoor air ventilation optimized. 

2.Frame: Galvanized steel sheeet, the layer of the galvanization is **0g/m2, and frame is one-off molded, also there is a out let in the bottom.

3.Fan Blades:6 pieces of Germany-imported mirro finished stainless steel blades, the fan translations all have passed the experiment of homeostasis, which makes the air volume keep the same as the very beginning during the operational life span of the fan.

4.Belt Pulley:The V type belt pulley is aluminium alloy injection moulded, so it is light and high-strength.

5.Belt: The belt is imported from Japan, it is a ametbolic in a longtime so there is no use to maintin it during its life circle.

6.Motor: The motor is high efficiency and low wastage of energy and have accredited 3C certifiction, the Grade of Protection is IP*4 and the insulation Grade is F.
