International Comfort Products PGAA24C1K1 Blower Wheel
The primary blower wheel is usually finned and is used in order to produce a steady airflow through a house. It is sometimes called a squirrel cage due to the clear similarity of a very large wheel a hamster would run on. However you decide to name it, it is definitely an important aspect that is necessary for proper airflow.
Important signs that the main blower wheel will soon need to be replaced
- If a part of the wheel has been twisted and it seems out of balance
- You may sense less than normal airflow coming out of the system
- A scraping sound can be heard when the system ramps up
