Greenheck’s new BAER belt drive sidewall propeller fan delivers expanded performance and improved efficiency in wall-mounted clean air applications. Features cast aluminum airfoil blades and hubs, an AC induction motor and an automatic belt-tensioning system that minimizes regular maintenance of the fan belt. The automatic belt-tensioner will adjust tension as the belt wears, easily doubling the life of the belt while maximizing the life of the fan and motor. Fan efficiency is also improved, as belt tension minimizes drive loss.
Available in exhaust configurations with propeller diameters from 24-36 inches, and performance capacities from 300 to 33,000 cfm and up to 3.3 in. wg. A range of sidewall accessories is also available.
