Amperage increases at more than three times the rate of airflow. The startup current for most correctly operating blower motors is low (usually less then 200% full load amperage), so the op's concern should not be much of an issue. 12v x 30a = 360 watts.

We cannot get the actual full load ampere because it depend on efficiency of motor.if electric motors have a higher efficiency rating,it will draw fewer amps, for example a 10 hp motor with a 60% efficiency rating will draw about 65 amps at 230 vac compared to about 45 amps for a motor with a 80% rating. At the bottom of this page is a video that’s very popular. I have a 4 speed 1/2 hp motor. A high unloaded amp draw signals an issue with the drive motor, over tensioned drive belt, bad bearings in the front and/or rear rollers, and/or an over tensioned walking belt.
