Lennox 47K28 Blower Wheel

When you are dealing with restricted airflow or severe unit vibration in a Lennox air handler or furnace, a compromised blower wheel is a likely culprit. The Lennox 47K28 Blower Wheel is a precision-engineered OEM replacement part designed for high-static applications. This 10-5/8" diameter by 8-1/8" width wheel features a 1/2" bore size and 48 concave blades designed for efficient air movement. It is a direct-drive component, meaning it mounts directly onto the motor shaft to deliver consistent CFM without the energy loss of belt-driven systems. As a verified identical replacement for R02592A003, this wheel ensures the mechanical balance and rotational specs (Clockwise Hub End) required to prevent premature motor bearing failure. Using this genuine Lennox part guarantees that your static pressure readings remain within the manufacturer's specified range (typically under 0.5” W.C.), maintaining the structural integrity of the blower assembly and preventing the "hunting" behavior common with unbalanced aftermarket alternatives.

• Factory Balanced Core: Prevents excessive vibration that can lead to direct drive blower motor fatigue and noisy operation.
• Direct OEM Compatibility: Replaces Lennox part numbers 47K28, 47K2801, 30M01, 48J89, and Allied/Armstrong R02592A003.
• Optimized Blade Geometry: Features a convex hub and 48-blade count to maximize HVAC airflow efficiency even in high-resistance ductwork.
• Industrial Build Quality: Heavy-duty construction designed to handle the high RPMs of modern Lennox furnace blower wheels.

What are the exact dimensions of the 47K28?
The wheel measures 10-5/8 inches in diameter and 8-1/8 inches in width, with a standard 1/2-inch bore for furnace blower motor shaft mounting.

Which direction does this blower wheel rotate?
This component is designed for CW (Clockwise) rotation when viewed from the hub end, which is critical for proper air discharge and motor cooling.

Can this wheel replace the 30M01 or 48J89?
Yes, the 47K28 is the current authorized substitute for those legacy Lennox blower parts, maintaining the same fit and performance profile.
