Fan series connection
Thread Content
What will happen if two fans with a large difference in performance are connected in series? Will the air volume handled by the smaller exhaust fan increase?
When fans of the same model are connected in series, the wind pressure increases while the flow rate remains unchanged. When fans of different models are connected in series, with the higher-pressure fan placed at the front, the flow rate does not increase; however, the wind pressure decreases due to the restriction imposed by the lower-pressure fan； Large fans are connected in series; the air volume and pressure remain unchanged. Therefore, it is not recommended to use fans of different models in series.
