Return-flow low-speed wind tunnel
● Uses a DC motor to drive the axial flow fan, resulting in good starting and speed regulation performance, a wide and smooth speed regulation range, strong overload capacity, and low susceptibility to electromagnetic interference.
● Matched with an imported brand DC speed regulator, it has a large speed regulation ratio and can obtain good torque characteristics throughout the entire speed regulation range, ensuring stable and reliable speed at both low and high speeds.
● The fan impeller is designed using aviation engine technology and manufactured using high-strength aviation aluminum alloy. The addition of front and rear guide vanes results in a highly efficient axial flow fan with low temperature rise, low noise, and high air quality.
