Lennox G40UH-60D-135 Blower Wheel
The main blower wheel is finned and is used in order to produce an airflow throughout an entire home. You may also see it named a squirrel cage due to the resemblance to that of a pet hamster wheel. Whatever you want to call it, it remains a vital device of a heating and cooling system that needs a good amount of airflow.
