The Lasko Pro-Power B20548 is a 20-inch box fan built for workshops, garages and sheds rather than bedrooms. Its steel body carries over 25% more steel than standard box fans, and the Wind Ring shroud is claimed to push up to 20% more air velocity. A Weather Shield motor lets it sit in a window without rain worry, and the fused safety plug adds protection. Against ordinary plastic box fans it is heavier, sturdier and louder; owners rate it well for moving serious air, while some find the top-mounted controls basic and the fan noisy at high speed.
