When many customers are looking for DC axial fan, they usually look at the nominal current or power of DC axial fan. They think that the same effect can be achieved only when the power is so high. Is the relationship between the power of DC axial fan and the air volume proportional?
First, for the same material, the same design, the larger the power, the larger the air volume, but to a certain extent, the power increases, the speed increases little, or does not increase with the original, so the air volume will not increase.
Secondly, for different materials, different designs, it is possible that DC axial-flow fans with smaller power are larger than those with larger power from another fan factory. For example, large motors are generally less powerful than small motors for fans of the same size, but the volume of fans can be larger. For example, with the same specifications, the same speed, the same air volume, generally single-winding energy-saving drive circuit is more energy-saving than double-coil drive circuit.
