increased air flow
*Dimension-54 inch(W 1380*H1380*T448mm)
* Galvanized housing ,guard rail and louver leaves,zn-coat thickness ≥200g per square meter,resistant to corrosion and weathering; SUS430BA mirror finished stainless steel blade
Housing thickness-1mm;blade thickness-1.2mm
Middle main louver leaf thickness-1.5mm;other louver leaves thickness-0.8mm
*Each forper fan is passed balancing testing for three times to
guarantee high strength, increasing air flow and low noise.
A static balancing testing- Weigh fan blades by electronic scale to ensure all the 6 baldes of a fan have the same weight.
A dynamic balancing testing-Proof the angle of six halves of a flange to guarantee they have the same angle.
Another dynamic balancing testing-Test assembled blade and flange in operation by dynamic balancer to ensure equilibrium amount of each blade is no more than 1g.
*die casting and numerical control machining aluminum wheel;
Self-sealing pillow block bearing, good flexibility and long life span
*Automatic belt tensioner,belt type-89 (MITSUBOSHI), with high strength and long life span.
*3C,CE approved energy efficient motor :
*Both sides of every fan are equipped with hand rail, making easier for transportation and installation.
