J&D Manufacturing Model #CF60 White UL Listed Spray/Corrosion Proof Variable Speed Ceiling Fan (60" Reversible, 9,415 CFM, 120V)

The AirFiciency Indoor/Outdoor ceiling fan provides a healthier, cooler
environment for your animals all year long. In the summer, the fan
creates a mild wind chill to help poultry and livestock. It vertically
mixes warm stagnant air above and in between animals, reducing
heat stress to keep production at maximum levels. It also disperses
hot pockets which can be a breeding ground for germs and bacteria.
In the winter, the ceiling fan prevents warm air from collecting in the
rooftop and peaks which produces condensation that drips down on
animals and bedding surfaces. Instead of wasting the valuable winter
heat that collects in peaks, the heat is mixed and circulated throughout
the building, saving on energy costs and keeping your animals comfortable.
Throughout the year the AirFiciency ceiling fan dries bedding to reduce
slippage, and also dries litter, walls and floors. The continuous circulation
dissipates ammonia, gasses and odors to keep the air not only cooler,
but fresher too.
