Misting Fans

Heat stress is an indicator of unsafe and unhealthy work or play circumstances. Heat stress has been documented to contribute to dangerous conditions such as heat stroke, fainting, cramps, vision impairment, and dehydration. Capable of cooling a large area down by as much as 35 degrees Fahrenheit, the Mighty Mister Misting Fan can last up to 8 hours! Fitted with wheels and a handy folding tow handle, the Mighty Mister Cooler Misting Fan is not only lightweight, but the Misting Fan can be stored in the Cooler during transportation or storage. Extremely energy efficient and affordable, the Mighty Mister Misting Fan is the way to go for both portable applications and anytime regular Air Conditioning is impossible.

Easily transportable, the VersaMist Misting Fans are a unique and clever misting cooling systems solution that simply attaches to the Igloo 10 gallon drinking cooler. Simply fill the cooler with cold water, insert the misting hose, attach the lid, hook the misting fan up to an AC Plug-in or choose the DC power supply model and turn on the misting fan. Schaefer Ventilation VersaMist Cooling Misting Fans can last up to 5 hours. Effective enough to cool an area of 180 square feet and lower air temperatures as much as 35 degrees Fahrenheit.

Stepping up the ladder in overall power and cooling ability, the Schaefer Ventilation VersaFog is a high-power, high-pressure cooling fog misting fan that can move up to 11,000 cubic feet per minute of cooled air. Mounted on a wheeled platform for easy transportation and set up in Fan Oscillation mode, this extremely effective air cooling system cannot be beat for pure cooling power and energy efficiency. The VersaFog can actually reduce air temperature as much as 35 degrees Fahrenheit!. Look to Schaefer Ventilation cooling misting fan systems to solve even the most challenging cooling problems and provide years of trouble-free use.

According to wiseGEEK, "A typical misting fan works on the principles of thermal dynamics and evaporative cooling. If you place a wet towel in front of an electric fan, you may notice the area around the towel becomes noticeably cooler. As the water from the towel evaporates, it takes a certain amount of heat energy along with it. The fan circulates the cooler air around the room, acting like a rudimentary air conditioner. Misting fan technology takes this idea of evaporative cooling and makes it much more efficient and productive."

Water is the key to misitng fans. Special high-pressure pumps generate a water pressure of 1000 PSI (pounds per square inch). Super fine nozzle openings compress the outbound water into micron-sized droplets, creating a thin mist. The mist evaporates upon contact with the warm air. These tiny droplets actually pull heat as they evaporate resulting in a significant temperature drop. An electric fan pushes this cold air and mist combination for several hundred yards or more.

Because the mist created by a misting fan system is so fine it is very unlikely that one would become wet, unless you are less than 6 inches (15 cm) away from the water nozzle. Misitng Fans usually filter the water supply and rarely use more than 1 or 2 US gallons (about 3.8 to 7.6 liters) per hour.

Misting Fans were originally created to cool crowds of people in outdoor arenas or stadiums, however, smaller home units are becoming popular. Misting fans are great for around the pool, backyard gardens, outdoor garages or while mowing the lawn.

How A Misting Fan Works

A standard fan uses evaporative cooling to create a cooling effect. When you sweat the fan circulates air over your skin and causes the perspiration to evaporate. This moving air efficient at removing radiated heat from your body.

A misting fan simply adds water to this basic principal. A fine spray of water is combined with the air movement of the fan. The water absorbes the heat and then evaporates, thus cooling the surrounding air up to 30 degrees. Misting fans work best in areas with low humidity.
