1.Really big air volume: The product can reach a maximum wind speed of 30ft, compared to 22ft for regular tower fans. It addresses the big sore point of the tower fan being soft but not strong enough. There is currently no comparable tower fan on the market that can match its volume of air. 2.Fixed Structure, Stable Air Supply: Traditional tower fans shake their heads, and the slightest touch can cause the entire fuselage to vibrate, especially if you have a baby crawling across the floor. Our product is a fixed body with only the Outlet strip swinging. The air supply angle is actually the same, but it makes the product more stable.
