Lennox CB28UH-036 Blower Wheel
The main blower wheel is like a squirrel cage that is attached to the main blower motor, which is used as to provide air circulation to all the ducts. It can also be called a squirrel cage because of its likeness of an oversized wheel a hamster might run on. Whatever you decide to call it, it is definitely an important device of any heating or cooling systems that requires proper air circulation.
