Fujitsu ASU30CLX Blower Wheel
The main blower wheel is commonly finned and is traditionally used to produce a steady airflow through all the ductwork of a home. It is sometimes referred to as a squirrel cage because of its unusual semblance of a hamster wheel. Whatever name you use, it remains a vital device of any HVAC system that needs suitable airflow.
Symptoms of a deteriorating main blower wheel
- A rattling sound is audible when the system ramps up
- If any part of the wheel has been damaged and it spins lopsided
- You notice a lot less flow of air
