Yeah I'm sure it'll clear a 4x4x7 with no problems. It's very strong. The only caution I would give is that if you need it to be slower in speed for noise or to slow down the exchanging of air the dial doesn't help much. It really only feels like High and Medium not really a low you know what I mean. It's a great fan, and not very noisy imo, course I keep it outside my tent in the attic area
