1. Rotation direction
(1) When facing the inlet of a centrifugal fan, the fan impeller rotates clockwise, which is left rotation. If it rotates counterclockwise, it means the centrifugal fan is rotating to the right.
(2) When standing at the "tail" position of the centrifugal fan motor - if the impeller rotates clockwise, it rotates to the right; if it rotates counterclockwise, it rotates to the left.
The rotation direction of the centrifugal fan is also determined based on the user's working conditions and environment. Only when installed correctly, can a centrifugal fan convert the input mechanical energy, increase the gas pressure, and discharge the gas, thereby accelerating the flow speed of the fan airflow, improving the efficiency of the fan, reducing time delay costs, and increasing user benefits.
2. Angle
Judging from the position of the "tail" of the motor, the air outlet is 0 ° to the ground, 90 ° vertically upwards, and 180 ° parallel to the ground. Other angles can be adjusted according to the increase or decrease.
The rotation direction of a centrifugal fan is easy to determine as long as it stands in the correct position. However, if you stand on the bearing side, it is easy to make installation errors and cause inconvenience during use, which can affect exhaust.
