How does the muffler go over the fan?
i'm currently just using a booster fan for my exhaust. my setup is as follows...hood...booster fan....ducitng exhaust into other room. i have an ocilating fan and intake as wellyour... BOOSTER fan is loud? your 240cfm (when used in-line w/ a high cfm fan pushing it) is loud?
Replace it, the bearings are obviously going out, n they are like what, $22?
it does not go over the fanHow does the muffler go over the fan?
Ya I have my fan mounted directly on the hood...its not super loud or anything.. very slight vibration...the air its moving seems to be the problem. would mounting the fan help reduce the sound of the air flowing? I'm also using a 25ft duct( most of it it scrunched up)....cut in half?perhaps its time for liquid cooling? Seriously, a 6" booster fan on its own pushes AT BEST 160cfm... its what "booster" fans are designed to do. 160 free air movement, 240 pass thru w/ a real fan at one end....
So at 160cfm thru a 6" tunnel.... what is the god awful noise your hearing if it's not mechanical? Maybe you got the wrong brand n its got a loud motor or something? I just can't imagine this amount of air movement, or this small and low power of a fan is producing noise to a level of irritation...
Also... Is your fan connected direct to the hood? Cuz that sounds like it'd be noisy as hell.....
hood, duct, fan, duct to exhaust port. Mount/hang the fan. (i like rubber bungee straps w/ a piece of foam behind so absorb vibrations. Eye hook on either side to hook to. Foam I use comes from local old lady yarn shop, lol.)
Cool, they've never been on my radar before now.it does not go over the fan
it get attached to the fan ...........before the fan and after the fan ................it will reduce the sound the fan makes and keep it from echoing down the ducting
to stop the noise from the fan u need to incase it with the foam like i said
