Ducting for multiple extractor fans

jamesy · 14 Apr 2003

Hi all. Does anyone know if it is possible to run three fans into one duct. As well as saving money on the ducting I thought that this would mean I only need one unsightly outlet. Ideas appreciated.

Unless each one has a "non return valve" then i would say no, if you have no non return valve which ever one is running bill send air back down the ones that are not.
