Fan, axial
A fan with blades that turn around a shaft. The blades force air to move parallel to the shaft, so air blows across the axis of the fan.
Fan, centrifugal
A fan which pulls air in near the shaft and forces it outwards. The air exits through an opening in the outer edge of the scroll-shaped fan casing. A centrifugal fan produces more pressure for a given air volume than an axial fan.
Fan, radial
See fan, centrifugal.
Full load current
The amount of current a motor will draw when operating fully loaded and at full speed.
