EcoJet's Tornado 21" Wall Mount fan is one of the most powerful misting fans on the market. This industrial strength wall mount fan provides a superfine mist and operates quietly. Tornado is generally used in large scale cooling applications such as industrial plants, warehouses, loading docks, barns, livestock pens, poultry houses, community and church camp areas. The wall mount fan connects directly to a fixed water line or hose and hangs on a large L - shaped bracket that comes with the fan along with mounting hardware. It’s recommended the fan be mounted high on the wall so the mist can drift down and slowly spread out into the desired cooling area. Tornado will reduce area temperature 20+ degrees in the cooling area. The mist cloud effectively cleanses the air of dust and fine particles, odors and pollen. It also reduces static electricity and creates a bug free fly zone. Tornado provides the same superfine mist as the other EcoJet fans, and will not drench people and equipment. EcoJet's patented disk technology breaks water molecules down to 4-10 microns, much smaller than the industry average. Cools up to a 3,000 square foot area.
