Reflux low-speed wind tunnel-I

Using a DC motor to drive the axial flow fan has less impact on the test results of the product. No electromagnetic interference to the DUT.
The fan and fan are designed with aero engine technology and apply high-strength aerospace technology.
It is made of gold and aluminum, and is equipped with front and rear deflectors, so that the manufactured axial flow fan has high efficiency, low temperature rise, low noise and high wind field quality.
