Customers often ask whether the DC fan can be adjusted in speed? Is there something like a knob on the fan that can be adjusted casually? The speed adjustment function is one of the main differences between a DC fan and an AC fan, but it depends on how to adjust it. The adjustment method used is mainly related to the matching of the client. The DC fan itself is a fixed motor and will not change. However, the speed of the DC fan can be changed when the external conditions change.
If the speed is adjusted according to the high and low frequency, the computer CPU fan is commonly used. If you change the input voltage of a DC fan, the most common one is a handheld DC fan
DC fans can be customized with different high and low speeds according to customer requirements. Some people say that AC fans are also possible, but AC fans only adjust the speed within a small float, while DC fans have a very large adjustment float, 10% of the small speed. Up to 100%. The cost of high and low speeds may also vary several times.
