Rheem-Ruud 70-18625-01 Blower Wheel

The Rheem-Ruud 70-18625-01 is a precision-engineered blower wheel designed for high-static efficiency in residential and light commercial HVAC applications. This 10 5/8" diameter x 9 1/2" wide component features a 1/2" bore designed for a secure fit on standard motor shafts. Configured for CW rotation (clockwise), this double inlet blower wheel utilizes a concave fin design to optimize CFM output while maintaining structural integrity under high torque. As a direct-drive component, it eliminates the inefficiencies of belt-driven systems, ensuring consistent airflow across various duct configurations. This model serves as the official OEM replacement for the discontinued 70-18625-03, engineered specifically for Rheem-Ruud furnace and air handler units. Proper installation requires checking the motor shaft alignment to ensure vibration-free operation and maximum heat exchanger performance. Selecting this centrifugal blower wheel ensures the air distribution system meets the original equipment manufacturer's static pressure specifications.

Key Application Benefits:

• Direct Drive Compatibility: Matches factory specifications for 1/2" shaft furnace blower motors.
• Enhanced Airflow: The double inlet design maximizes air intake for efficient cooling and heating cycles.
• Exact OEM Replacement: Replaces 70-18625-03 without the need for housing modifications or re-balancing.
• Dynamic Balancing: Concave fin construction reduces harmonic vibration and extends the life of the motor bearings.

Common Technical Questions:

What is the difference between 70-18625-01 and 70-18625-03?
The 70-18625-01 is the current technical revision. It shares the same dimensions and performance curve but features updated manufacturing tolerances for improved balance.

How do I confirm the rotation of this blower wheel?
The 70-18625-01 is rated for Clockwise (CW) rotation. Always verify rotation by looking at the wheel from the hub side to ensure it matches your motor's lead orientation.

Can this wheel be used in a belt-drive system?
No, this is a direct drive blower wheel. It is designed to be mounted directly onto the motor shaft and is not reinforced for the side-loading tension of a belt-drive pulley system.
