Desa R155B Blower Wheel
The blower wheel is the primary device that is spun around by a motor to provide forced air through all the ductwork of a home. It can also be called a squirrel cage because of the striking resemblance to that of a hamster wheel. However you decide to name it, it is still a crucial device that is needed for proper airflow.
