Bath Fan Noise
Flex ducts need to be pulled tight and sloped to the exterior wall if possible. The bath fans in this development have had a problem with the bath fan noise bothering the new owners. The fans are now set at 5 cfm for a total of 10 cfm for a building that requires 30 cfm continuously from each fan to meet ASHRAE 62.2 2019. The static pressure caused by the size, length and installation of the ducts causes the fans to use more power to move the air with significantly more noise. One solution is to drop the bath ceiling and run the ducts strait out of the building. Another is to use a remote bath fan such as the Fantech PB 110. Click HERE. Mount it to the joist or trusses using these. A third choice would be to use six inch duct.
