This 18 In. High Velocity Wall Mount Fan is a great choice for a large barn, workshop, garage, factory, commercial warehouse, or gym where industrial grade air circulation is required. It's built tough with a powder-coated steel housing in black finish and features a totally enclosed motor to prevent dust and other particles from clogging and damaging the motor and other critical components. This ensures a longer life in the field in challenging indoor locations. The electric wall fan arrives to you fully assembled for your convenience—it's mountable on a wall or ceiling to save your floor space, and takes advantage of 3 powerful speeds operated via rotary switch on the rear grille. Ensure the airflow is properly dispersed through your space with 180° of tilt. Choose between a 3 prong plug model for typical indoor situations or a GFCI plug to operate safely in covered locations like a restaurant or home patio.
