Aero-Cool Fan is a revolutionary oscillating 18" misting fan. A 5 nozzle hub is built right into the grill of the fan! The 5 nozzles help to disperse the water vapor over a wider area of coverage to produce an evaporative mist and cool your patio or warehouse up to 30 degrees F. This fan will make a "cool"ing addition to any patio. Add a misting pump to provide the best atomization and patio cooling. (nozzles and nylon sold separately)
