Lennox 47K30 Blower Wheel

The Lennox 47K30 Blower Wheel is a factory-authorized, single-inlet centrifugal component designed for high-static residential and light commercial HVAC applications. This 11-inch diameter by 9.5-inch wide wheel is engineered for direct-drive configurations, featuring a precision-machined 1/2-inch bore for secure mounting on standard motor shafts. Constructed from heavy-duty galvanized steel, the 47K30 utilizes a forward-curved blade design to optimize airflow volume and maintain system pressure. This specific part is a direct replacement for Lennox R02592A023 and 47K3001, ensuring exact physical and performance matching for Lennox GCS and CHP series units. Factory balancing minimizes rotational vibration, protecting the motor bearings and reducing decibel levels during peak operation. When replacing a furnace blower wheel, verify the concave hub position and clockwise rotation to ensure compatibility with your existing blower housing and direct drive blower motor equipment.

• Universal Cross-Reference: Fully compatible with part numbers 47K30, R02592A023, and 47K3001 for streamlined inventory and repairs.
• Industrial-Grade Build: Heavy-gauge galvanized steel construction resists corrosion and prevents blade deformation under high temperature or high RPM.
• Enhanced Airflow Efficiency: Forward-curved blade geometry provides superior air movement for consistent climate control and HVAC part performance.
• Vibration-Damping Design: Each wheel is precision-balanced to ensure smooth operation, extending the operational life of the connected motor and shaft.

What are the symptoms of a failing Lennox 47K30 blower wheel?
Contractors typically report excessive vibration, "banging" or "thumping" noises, or reduced airflow at the registers. Inspect blades for dust buildup, cracks, or hub separation from the wheel structure.

How do I ensure the 1/2-inch bore fits securely?
Always clean the motor shaft with an emery cloth and ensure the flat side of the shaft aligns perfectly with the set screw. Proper torque on the set screw is critical to prevent the wheel from slipping during high-torque startup cycles.

Can the 47K30 replace other 11x9.5 wheels?
While dimensions match, you must confirm the bore size, rotation direction, and hub projection. The 47K30 is specifically balanced and specced for Lennox HVAC systems to meet OEM performance curves.
