International Comfort Products NAC036AKA1 Blower Wheel
The main blower wheel is a finned wheel that is spun around by a motor to produce a steady airflow through all the ducts. It is occasionally called a squirrel cage because of the noticeable alikeness to that of a hamster wheel. However you decide to name it, it is still a very necessary aspect of any heating or cooling systems that requires proper air circulation.
Important clues of a declining blower wheel assembly
- Clanking sound can be heard as the blower starts to turn
- If one of the fins has been damaged and looks unbalanced when it spins
- You observe lower than normal air coming from the vents
