This replacement motor fan is designed to support airflow restoration in riccar vacuum parts systems and simplicity vacuum platforms. Built for compatibility with models using the B123-3000B part number, this component fits a wide range of vacuum cleaner configurations that rely on internal motor fan performance for proper suction. Compatible with riccar vacuum cleaner models including the Supralite and Lightweight series such as RSL1, RSL1AC, RSL3, RSL4, and RSL5, this motor fan also supports simplicity vacuums including S10E, F3300, F3500, F3600, F3700, and R10E. This shared motor platform between riccar and simplicity allows this component to serve as a reliable vacuum replacement part across both product lines. Designed to function within vacuum motor systems, this fan plays a critical role in maintaining airflow and suction consistency. When the original fan becomes worn or damaged, replacing it helps restore the vacuum cleaner's ability to perform effectively in both home improvement and light commercial vacuum cleaner environments. This component is ideal for users performing maintenance on vacuum cleaner parts, particularly those working with vacuum motor repair or dust collection optimization. It supports airflow performance in systems that require stable motor operation and efficient air movement. The design allows integration into existing vacuum parts assemblies without the need for replacing the full unit. It is suitable for maintenance professionals as well as users managing routine repairs in residential settings. Package includes one replacement motor fan only. This listing does not include additional vacuum cleaner parts such as motor housing, carbon brushes, or external components. Users should verify compatibility by matching the B123 3000 part number or confirming alignment with their original component before installation.
