Description

commodity description: Air capacity:****0m3/h Size:***0×***0×**0mm Noise:≤*4dB Power:1.1kw Voltage:**0V Electric current:2.8A Weight:*8kg Material: Frame: galvanized steel sheet, the layer of the galvanization is **0g/㎡ï&frac*4;Œand the frame is one-off molded, also there is a outlet in the bottom. Fan Blades: 6 pieces of mirror finished stainless steel blades with the diameter of ***0mm 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 *0 degree under all the condition. And uncontrollable air can never goes into the birdhouse as the shutter works. 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. Motor: The motor is high efficiency and low wastage of energy and have accredited 3C certification; the Grade of Protection is IP*5 and the Insulation Grade is F. Maintenance free: there is no use to maintain it during its life circle. Performance: it is used to ensure the minimum and transverse ventilation in spring and fall and it usually works with the air inlet.
