Why is my DELTA BREEZ SIG80 so loud?
- KkristaelliottJul 28, 2025
There could be several reasons why your DELTA BREEZ Fan is louder than expected: * The CFM (cubic feet per minute) rating may be too high for the room size. Ensure the fan's CFM rating matches the room's requirements. * The damper might not be working correctly or could be damaged. Check that it opens and closes properly. If damaged, contact Customer Service. * A sharp bend in the duct might be too close to the fan discharge (less than 18 inches). * The ducting might be smaller than recommended, increasing noise. Use the recommended size ducting. * The fan body might not be securely attached to the ceiling joists. Make sure it's firmly attached.
