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. zn-coat thickness no less than 200g/㎡,resistant to corrosion an 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.
