Query: Moves the air

Performs well at either of the 3 speeds. Clears the dust in the air out of my shop (40' x 28' x 8') with no issues. The LED lights are not very good and seeing them is difficult, but who really cares? You can hear the 3 speeds well enough to know where you are at. The audio beeps are loud enough to hear so you know when you are changing the speed or turning it off. Easy to install, but you should have two people to lift and get it into the final install position on the ceiling.
