Product description
The 12 Inch Dia, 5 Blade, 25 Deg Pitch, Ccw, 5/16 Bore Acme 31215 is a precision-engineered fan blade designed for efficient air movement in commercial and industrial HVAC applications. This fan blade features a 12-inch diameter and a 5-blade configuration, optimized with a 25-degree pitch to deliver a high volume of airflow while maintaining structural stability. The Counter-Clockwise (CCW) rotation is designed to match specific motor and housing configurations, ensuring the correct direction of air delivery. With a 5/16-inch bore, it is compatible with a wide range of standard small-frame motors. The blades are constructed from high-quality materials, typically aluminum or galvanized steel, to resist corrosion and mechanical deformation under high rotational speeds. This Acme fan blade is a critical component for maintaining the cooling or ventilation capacity of condensers, evaporators, or exhaust systems, providing reliable and quiet performance.
