OK this is probably a really stupid question but I thought I ask...
I would like to get a high power exhaust fan for my bath. Most of them use
6" duct to vent to the roof. My roof vent is 4" and I don't want to change
Can I get a fan for 6" and then use a reducer to go from 6" to 4" duct then
to the vent?
Will this make it work "better" than a regular 4" exhaust fan?
I think this is a bad idea...
