Sell 50" fan,exhaust fan, axial flow fan,negative pressure fan,ventilator @China (Mainland)

1.Fan frame: it is formed in one step due to the use of advanced automatic processing technique, the thick zinc coating (150g/m2) ensures great corrosion resistance, the bottom outlet design makes fan structure more reasonable. 2.Belt pulley: The V-shaped hub made of aviation aluminum alloy is light, tensile, high-strength, and unlikely to break. 3.Fan blade: six stainless steel blades which are formed in one step are aesthetic, durable and resistant to deformation, the blade passed the dynamic balance test and its reasonable angle ensures maximum air flow and minimum noise. 4.Shutter: High strength hot galvanised plate, the automatic opening-closing device makes it possible to open and close louvers completely, maintain a 90-degree opening angle to ensure louvers are windproof, rainproof and dustproof. 5.Motor: V type belt is durable ,high energy efficient, 3C approved, IP55, class F insulation. 6.Belt: Imported B type belt is long lasting, deformation resistant , and requires no maintenance. 7.tests: Aonuodi standard exhaust fan is subjected to noise test, vibration test, concentric performance test, fan blade speed test .air flow test and efficiency test, so as to ensure its quality .
