There are many types of fans, and the effects of different types of functions are naturally different, so you must grasp as appropriate in your choice. There are many fans installed in many workshops, but the workshop is still very sultry. This is definitely the fan that is not suitable. The following is the analysis of the difference between axial fans and negative pressure fans.

     The exhaust of the axial fan is on an axis. The example shows that if you stand beside the axis of the axial fan, you will not feel the airflow at all, although there is a lot of wind on the axis. Its air flow is linear, and it can rarely be driven by the surrounding air. It is like a high-pressure faucet spraying water. Standing on the side of the water flow, your body will not be wet.

     A negative pressure fan is like a reverse sprayer. Its absorption of air is horn-shaped. It not only drives the airflow from the axis of the fan, but also flares the air from the fan outward. We stand next to the axis of the fan. You will feel strong airflow. Its characteristics determine the thoroughness and high efficiency of its exhaust.
