So that I can clean and clean
Based on the aerodynamics of the streamlined duct design, the bell-shaped design forms a high static pressure
Area, a substantial increase in suction, and the duct wall of the wind side of the three sections of the arc design, smooth lead
Air flow, greatly improve the utilization of air volume, while increasing the fan wind angle, to avoid
Turbulence reduces noise and wind resistance, resulting in high static pressure and low noise.
