Desa R40 Blower Wheel
The blower wheel is commonly finned and is used to produce a steady airflow through all the ductwork of a home. It is sometimes called a squirrel cage because of its remarkable semblance of a very large wheel a hamster would run on. Whatever you decide to call it, it is still a crucial aspect of a heating and cooling system that needs proper airflow.
