This 18 In. Wall Mount Fan features wide grille openings that allow airborne debris to pass through, keeping the high velocity fan operating at top performance and making it a perfect choice for cooling indoor areas such as a commercial livestock barn, horse barn, or in a poultry coop to keep developing chickens and laying hens at their most productive. Mount the air circulator to a ceiling or wall in a large room using the pre-installed heavy-duty bracket. This commercial grade fan tilts up to 180 degrees for focused airflow with your choice of 3 speeds and uses a totally enclosed motor to protect from dust and other particles and ensure a longer life in the field.
