This company's new range of Aerofan propeller fans has a cast aluminum motor mount that provides a rigid and versatile platform, allowing a wide range of motor choices. An integral safety guard permits motor wiring without guard removal. Airflow is developed by a quiet and efficient adjustable pitch airfoil propeller in a deep drawn epoxy-coated venturi. Propellers are available in five or 10-blade versions, made of glass-reinforced polypropylene or pressure cast aluminum.
