Carrier 48XL-A30 Blower Wheel
The main blower wheel is commonly finned and is used as to generate airflow throughout a house. It is also named a squirrel cage due to the partial likeness of a very large wheel a hamster would run on. Regardless of what you call it, it is definitely an important piece of equipment that is necessary for proper air pressure within the ductwork.
Signals of a failing main blower wheel
