This Newair Outdoor Misting Fan is one of the most powerful fans on market, thanks to metal fan blades that deliver up to 2,800 CFMs to cool 600 square feet of patio, deck or outdoor kitchen space. Use the 3-speed fan alone, or connect it to a standard garden hose for refreshing mist that lowers temperatures by 10 degrees in arid climates west of the Mississippi river. Newair
