1. Blades are made of high quality stainless steel by CNC TURRET PUNCH PRESS, attractive and durable, special design of blade shae ensurng big air flow, no distortion, no broken, passing the homeosasis test to ensure the air volume keeing the same as the very beginning during the operational life span.
2. Siemens motor or Chinese famous motor can be chose, high efficient and energy-saving with CCC certificate. Protection class: IP55, Insulation class: F. The voltage, power, frequency and phase can be customized.
3. The bearing adopts special waterproof design of double-row bearing, high intension, low noise, maintenance-free and long service life.
4. Belt Pulley: Made of aluminum-magnesium alloy by injection moulded, reducing the weight of blade and impeller, high corrosion resistance. Blast-sanding treatment for attractive appearance, eliminating internal stress to improve its own rigidity and stability, high strength.
5. Swung drop hammer: 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, which is convenient for maintaining.

7. Belt impeller: Made of aluminum magnesium alloy by injection moulded, 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 moulded, reducing the weight of blade 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 and avoiding distortion, waterproof

10. Bearing: Imported double-row bearing, super mute, high intension and durable

11. Belt: China famous brand belt, Mistubishi belt

12. 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.

13. Guarantee period: One year. Easy broken parts are offered free of charge during this period
