The Imperial 1166 CCW Rotation Blower Wheel supports efficient airflow by moving air consistently through ventilation or heating systems. Designed with an 8-1/16" diameter, 2-1/2" width, and a 1/2" bore, it rotates counterclockwise to draw in and push air across components as required. The wheel works by spinning within a housing, creating airflow that helps regulate temperature and maintain proper system function. Equipped with two set screws, it allows for secure attachment to the motor shaft and stable operation. Its construction is suited for continuous use, contributing to improved airflow efficiency, reliable performance, and reduced strain on system components.
