Material of components:
1). Frame: Galvanized steel shee, anti-corrosive and durable, zinc thickness: 180g/m2. Thickness: 1.0mm for the top and 0.8mm for the other sides.
2). Fan Blades: 6 pieces of mirror designed Stainless Steel Blades, one-off molded, attractive and durable with big air flow, not easy to rust and never distortion and broken. Thickness: 1.2mm.
3). Motor: Siemens motor or Chinese famous brand motor, high efficient and energy-saving with CCC Cetificate. Protection class: IP55. Insulation class: F. The voltage, power, fequency and phase can be cuustomized.
4). Shutters: Made of high strength galvanized steel sheet, dustproof and waterproof. Thickness: 0.45mm.
5). Swung drop hamme: Made of high quality nylon, stable performance, guaranteeing the shutters open and close flexibly.
6). Protective net: Made of hard-drawn wire, designed as door type, convenient for maintaining.
7). Belt impeller: Made of aluminum magnesium alloy by injection molded, adopting more stiffening rib, processed by sandblasting, eliminating the internal stress, high intensity, low noise, long service life.
8). Belt pulley: Made of aluminum magnesium alloy by injection molded, reducing the weight of blades and impeller, high corrosion resistance. Blast-sanding treatment for attractive appearance, eliminating internal stress to improve its own rigidity and stability, high strength.
9). Belt tensioner: Made of high quality nylon or aluminum magnesium alloy, avoiding belt loosening or dropping off, extending service life of belt and avoiding distortion, waterproof.
10) Bearing: Imported double-row bearing, super mute, high intension and durable, adopting special waterproof design, maintenance-free and long service life.
11). Belt: Chinese famous brand belt
10). Strict test criterion: Consist of airflow test, nose test, libration test, drive concentric test, blade RPM test, whole machine efficiency test, dynamic balance test, the thickness of the galvanized sheet test, the size of the spare parts test, etc.
