This 13x11x1/2 blower wheel (often referenced by nominal dimensions of 13x7x7 in specific housing configurations) features a double inlet forward-curved design to maximize CFM output while maintaining structural integrity during high-RPM operation
preventing combustion air bypass and maintaining the precise fuel-to-air ratio required for peak thermal efficiency
Code 1 Matching: Precision engineering ensures that multiple B116 V-belts can be used in matched sets for balanced power sharing
It supports zoning system integration and enables the monitoring of indoor humidity levels and outdoor temperature sensors without requiring a direct Wi-Fi connection at the thermostat interface
High Horsepower Capacity: The raw-edge sidewalls and notched V-belt design offer significantly higher horsepower ratings than conventional wrapped belts
Lau 60718301 Fan Blade 320819-301 This 13x11x1/2 blower wheel (oftenWhen you're servicing a condenser in the field, you need a high performance 12 inch condenser fan blade that balances airflow demand with mechanical longevity. The Lau 60718301 is a heavy duty, 4 blade propeller engineered specifically for high static environments like commercial condensing units and HVACR ventilation systems. With a 27 degree pitch and clockwise (CW) rotation, this aluminum blade assembly is optimized for localized air movement,
