Destratifier Vertical 360 Fan 18" is a powerful fan that effectively mixes the heavy, cool, dense air that accumulates at ground level with the warm, light, thin air that lingers near the top of your facility. This creates a comfortable and consistent indoor environment from top to bottom. As a vertical, low-airspeed circulator, it is an ideal choice for maintaining air quality, and its impressive IP66-rated 3-year warranty backs Gold Star Motor. The fan is easy to install and requires no maintenance, helping you save on labor costs and reduce your heating bill.
