Main parts Description Features
galvanized frame Through strength test,square frame and round air guide sleeve are stamped and connected together by standard fasteners, using electric power and air tools. Zinc coat thickness no less than 200g per sq.m,resistant to corrosion and weathering.
louver leaves Hot galvanized louver leaves are also made by stamping mold. 1.5mm-thick middle louver leaf supports plastic automatic centrifugal opening device,ensuring no deformation after operation for a long time. When fan stops operation,all leaves will close tight,leaning no leak for air or light.
SS blade 6 stainless steel blades are self cleaned,with a stamping process by computer mathematical model.
V-belt V-belt from MITSUBOSHI,with high strength,long life span and little maintenance.
Automatic belt tensioner Aluminum magnesium alloy material,no deformation; Tensioned from the inside in order to avoid being distorted to reverse direction.
belt wheel and wheel hub aluminum magnesium alloy material,die casted,with better corrosion resistance. Water proofing groove in the belt wheel protects water against entering inside. Built-in oil bearing in auto industry,maintenance-free.
Automatic centrifugal opening device Injected by reinforced nylon,bearing drive structure included. When powered,the centrifugal opening device pushes louver leaves quickly and flexibly,then ideal temperature and ventilation can be reached within a short period.
Famous brand motor 100% copper cored motor,with CCC authentication. Protection grade-IP55;Insulation grade-F
Invisible handle Both sides of every fan are equipped with handle, making easier for transportation . Concave hole design avoids possible damage to handle when installation in the wall.
