The Exhale bladeless ceiling fan creates a vortex in your room. This Tesla inspired design utilizes the science of laminar flow. We created this video to show the vortex flow of the Exhale fan in a room with a smoke generator after many suggestions from our water demo. The smoke used is very light and although appears to be moving very quickly is quite gentle. Standard 34" Exhale fan in a 14x15' room with a 8' ceiling. Enjoy!
