Material:

Frame: galvanized steel sheet, the layer of the galvanization is 150g/square meter,and the frame is one-off molded, also there is a outlet in the bottom.

Fan Blades: 6 pieces stainless steel blades with the diameter of 1270mm and the angle of the blades is patented designed. The fan translations have all passed the experiment of homeostasis, which makes the air volume keep the same as the very beginning during the operational life span of the fans.

Shutter: high strength hot-galvanized steel sheet, with a centrifugal system which can ensure the shutter opens with the angle of 90 degree under all the condition.

Belt Pulley: the V type belt pulley is aluminium magnesium alloy injection moulded, so it’s light and high-strength.

Belt:the belt is imported from Japan it is ametabolic in a longtime so there is no use to maintain it during its life circle.

Motor: The motor is high efficiency and low wastage of energy and have accredited 3C certification; the Grade of Protection is IP54 and the Insulation Grade is F.Maintenance free: there is no use to maintain it during its life circle.Performance: it is used for longitudinal ventilation, the effect would be better if the fan translation works with a cooling pad.
