attic fan vibrations

i installed a Broan 1600cfm attic fan on my roof, now i hear the vibrations when it runs. the trusses are 2x4, 16 on center. how can i stop or cut down on the vibrations?

Re: attic fan vibrations

If I were you I'd go up there while it's running and see where it's loose and secure it, I don't know how it was installed but you may have to brace it with 2x4 or 2x6. Good Luck!!! :)

Re: attic fan vibrations

You can try to isolate the mounts with some sort of thick rubber or isolation pads. That's the best I can recommend not knowing how it is mounted.
Good idea to check that everything is tight too.
