International Comfort Products NAC218AKA1 Blower Wheel
A blower wheel usually has fins all around it and it is spun around by a motor to provide forced air through all the ductwork of a home. It is also called a squirrel cage because of the striking alikeness of a hamster wheel. Whatever you decide to call it, it is a necessary contraption that is essential for proper air pressure within the ductwork.
Major indications of a worsening blower wheel cage
- If a part of the wheel has been dented and it wobbles when spinning
- Scraping sound is audible as your system initiates
- You find much less air flow
