Portable Cooling/Misting Fans work by both creating wind movement and dispensing water vapor, giving the feeling of up to a 30-degree temperature drop. This model's tubular aluminum frame is lightweight yet durable, and its 8" tires provide mobility over a variety of surfaces. Ground fault circuit interrupters enhance electrical safety in wet environments, and the independent shut-off valve on each nozzle can help regulate the amount of cooling provided. This product would be especially helpful for people with difficulty regulating body temperature who want to continue working in hotter weather.
