Ao Smith rbw90131 Single Inlet Blower Wheel Cw Tab Lock

Product Description

The AO SMITH rbw90131 is a single inlet blower wheel designed for ducted forced-air systems. Built from galvanized steel, it delivers reliable airflow in residential and light commercial air-handling applications. The wheel measures 9-7/8 inches in diameter with a 1/2 inch bore, features clockwise (CW) rotation, and uses a tab lock hub for secure shaft attachment. HVAC technicians install this component as a direct replacement in blower assemblies where precise diameter, bore, and rotation direction must be matched to the original equipment.

This blower wheel is suited for ducted air-handling units, furnace blower sections, and fan coil assemblies that require a single inlet design. The tab lock hub simplifies field installation and reduces the risk of slippage under sustained load. Applications typically include residential gas furnaces, air handlers, and similar forced-air equipment where a 9-7/8 inch diameter single inlet wheel is specified.

Key Features

• 9-7/8 inch diameter single inlet design for ducted systems
• 1/2 inch bore with tab lock hub for secure shaft engagement
• Clockwise (CW) rotation — verify rotation direction before ordering
• Galvanized steel construction for corrosion resistance and durability
• Ducted application rated — not intended for ductless systems

Compatibility

Designed as an OEM-style replacement blower wheel for ducted forced-air systems requiring a 9-7/8 inch diameter single inlet wheel with a 1/2 inch bore and clockwise rotation.

Installation Notes

Installation should be performed by a qualified HVAC technician. Disconnect and lock out all electrical power to the air-handling unit before removing or installing the blower wheel. Confirm shaft diameter, rotation direction, and wheel diameter against the original equipment specifications before installation. Secure the tab lock hub fully to the shaft to prevent wheel movement during operation.
