With Multiple speeds, and Very low power usage. You can adjust the speed to your needs. In my case, I use it to pump warm air from our living room , into our bedroom down a hallway, that is not getting enough heat from our wood stove in winter time. I bored a hole through, above the bedroom door, and extended a 4 PVC pipe down the hallway , to get warm air at ceiling level, closer to the stove. because it takes almost no electricity to run, it's on full time....... Yes it looks a little weird, but hanging it fromlarge cup hooks, with straps, it can, all be removed after winter is over. And go right back up, next winter. IT WORKS GREAT !! UPDATE: power usage averages measured with my kill a watt meter is a follows. speed 1 = 1.2 watts, speed 3 = 3 watts, speed 5 = 7.5 watts, and speed 8 = 23 watts. note: watt reading bounces around on all but the high speed, because of the way it controls the speed. I leave mine on 3.
