How To Repair Misting Fans How To Repair Misting Fans
Misting fans may have to be repaired if they are not ejecting enough misting spray to cool the surrounding air. If a blade is broken or not functioning properly, you may have to replace it. Misting fans can be used in the outdoors, stadiums, and in homes. They can also be used in greenhouses and produce stores where they can cool down the temperature and provide moisture.
Misting fans operate on the principle of evaporative cooling. They eject streams of microscopic water droplets, which evaporate on contact with the hot atmosphere. As the droplets evaporate, they take some of the heat with them, thereby lowering the temperature. The effectiveness of misting fans is highest in dry areas; however, some of the models available today can handle humid climates as well.
Step 1 – Identify the Problem
Three common problems you may encounter are: the fan base or the fan blades not running, a lack of misting and leaks from the nozzles or draining area. A lack of misting is most probably because the water in the unit tank has run out. In this case, you can simply refill the tank and the problem will be solved. If there is a leak, check the drain plug that is used to drain the water in the unit. Also, check the air hoses for any openings. Properly seal any cracks and tighten the drain plug to solve the problem.
Step 2 – Check the Connections and Switches
If your misting fan is not running, check the power cord. Make sure it is connected properly to the power supply. If the switch is turned off, turn it on. If the problem still persists and the fan blades are not moving, proceed to the next step.
Step 3 – Open the Fan Grill
Remove the fan assembly from the base motor by using a screwdriver to unfasten the screws. Use a screwdriver to open the covering grill. Check the fan blade for any signs of damage or breakage. If there is damage, you will have to contact the manufacturing company to purchase a new blade for your model. If the blades look undamaged, the problem may be a lack of lubrication. Proper lubrication should fix the problem and the fan should operate properly.
Step 4 – Check the Nozzles
The misting spray emitted by the nozzles should be even and must cool the surrounding air. If this is not the case, the nozzles may need some cleaning. Most of the time, the problem is caused by calcification and mineral buildup. You can easily fix this problem by first disconnecting the power supply, removing the nozzles, and soaking them in vinegar for sometime. Wash the nozzles with water and reconnect them.
Step 5 – Clean or Replace the Filters
The filters must be cleaned regularly to ensure optimum performance. You can clean the filter by simply holding it under running water till all the particles are removed. Depending on the condition of the water you are using, you must replace the filters regularly. The recommended duration between filter replacements is 6 months. You must also treat the water in the tank with chlorine every month. Following some or all of the above steps to repair your misting fan will have it running like new in no time!
