What is the relationship between the power of the DC axial fan and the air volume?

When many customers are looking for a DC axial fan, the common practice is to look at the nominal current or power of the DC axial fan. They think that with such a high power, the air volume can achieve the same effect. The relationship between the power of the axial fan and the air volume Is it proportional? First, for the same material and the same design, the greater the power, the greater the air volume, but to a certain extent, if the power is increased, the speed will increase little or not, so the air volume Secondly, for different materials and different designs, it is possible that the air volume of a DC axial fan with a smaller power is larger than that of another fan factory with a larger power. For example, fans of the same size generally use the power of a larger motor. It is smaller than using a small motor, but the air volume can be made larger. For another example, with the same specifications, the same speed, and the same air volume, a single-winding energy-saving power-saving drive circuit generally saves more power than a double-coil drive circuit.
