Use our standard 18 In. Wide Guard Wall Mount Fan for small indoor ag areas such as a livestock barn, horse barn, or in a poultry coop to keep developing chickens and laying hens at their most productive. This industrial fan is built for longevity, pairing a totally enclosed motor protected from dust with wide grilles whose openings allow airborne debris to pass through the fan, keeping the blade assembly and components free to operate at maximum efficiency. Mountable to a ceiling or on a wall with the pre-installed heavy-duty bracket; just plug it into a standard electric outlet to cool your space with 3 powerful speeds and a 180° tilting fan head.
