The fan flange adopts a circular hole on one side and an elliptical hole on the other side

The fan flange adopts a design with one circular hole and one elliptical hole, mainly based on the following engineering requirements and advantages:

Installation convenience and fault tolerance

Adjustment space for elliptical holes: Elliptical holes allow bolts to be fine tuned along their long axis during installation, compensating for flange alignment errors or pipeline axial deviations, especially suitable for scenarios where on-site installation space is limited or precision requirements are not high.

The fixing function of the circular hole: The circular hole end ensures the stability of the bolt after tightening through precise fitting, preventing the flange from displacement due to vibration or external forces.
