Qingdao Shuangjunli Machinery Co, Ltd

We are qingdao shuangjunli machinery co, ltd based in qingdao , China. We are member of Tradekey.com since November, 2008. Our business is related to Agriculture industry and we specifically deal in exhaust fan cool pad ventilation fan. Please find our product details below: exhaust fan Air capacity:43070m3/h Size:13801380450mm Noise:≤64Db Power:1.1kw Weight:88kg Voltage:380V Electric current:2.8A Material: Frame: galvanized steel sheet, the layer of the galvanization is 280g/m2.and the frame is one-off molded.also there is a outlet in the bottom. Fan Blades: 6 pieces of Germany-imported mirror finished stainless steel blades with the diameter of 910mm 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 fan. 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. 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 IP55 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 fan Air capacity:43070m3/h Size:13801380450mm Noise:≤64Db Power:1.1kw Weight:88kg Voltage:380V Electric current:2.8A Material: Frame: galvanized steel sheet, the layer of the galvanization is 280g/m2.and the frame is one-off molded.also there is a outlet in the bottom.
