Why is the Esta Fan suction too weak?
- RRoy MartinAug 10, 2025
Weak suction in your Esta Fan could be due to several reasons. First, the filter may be soiled, requiring cleaning. Alternatively, the throttle in the suction pipe system might be closed too much; try opening it more. A clog from deposited residue in the suction pipe system could also be the culprit, so inspect and clean the system if needed. Finally, the cleaning point may be too low, preventing proper filter cleaning, in which case you should contact ESTA customer services to adjust the cleaning point.
