Ceiling fans are commonly accepted in residential environments, and are also a staple in commercial and industrial environments. However, unbeknownst to many, they are extremely useful in agricultural settings, and other harsh environment situations where they are exposed to dust, moisture, water, and the elements.
The benefits of using agricultural type ceiling fans include: air mixing and heat destratification, creating a wind chill for evaporative cooling, reducing condensation and moisture, keeping floors and walls dry, dispersing fumes, and discouraging flies, insects, and birds. For agricultural situations, studies have shown the use of fans increases production as livestock is more comfortable, and decreases diseases such as pneumonia. In any situation, ceiling fans have shown to reduce heating and cooling costs and decrease energy bills by as much as 30% when used correctly. They can also be useful in other outdoor situations such as stadiums, reclaiming lost heat and directing it back down on patrons.
Of course typical ceiling fans can not withstand being used under these conditions. Many industrial ceiling fan manufacturers offer fans specially outfitted and treated for agricultural settings and harsh environments. These fans have fully sealed motors and bearings, and epoxy coated finishes resistant to moisture. They are not only designed to withstand moisture but also dust. In most cases the agricultural/harsh environment fans are also the largest and most powerful fans offered by each manufacturer. These fans are recommended for agricultural settings such as horse, poultry, and dairy barns, greenhouses, stadiums, automotive garages, car washes and anywhere else fans may be mounted outside and in the path of water. Different manufacturers offer different features for their harsh environment fans. Here are a few popular and highly recommended models:
