I bought RUCK RKW 150-L 700m3 fan, Rhino Pro Filter 150/600 and over 15' of acoustic ducting.

My original idea was to connect the filter directly to the fan, then connect the ducting and hang its end outside. I figured this setup would be most efficient and quiet. Actually I even like/liked the concept of Foothill filters best.

But now I read some places that if the fan is attached to the filter a lot of noise would escape from/through the filter and the vibration of the fan can settle/unsettle/whatever the carbon in the filter. Even retailers "recommend using a short length of ducting between the fan and filter (just enough to keep them separated from each other, or as much as necessary for your application) to keep vibration from causing the carbon in the filter to settle".:what:

Is that true?

It seems absurd to insert ducting after the filter and double the number of potential failure points.

What are your thoughts?

I can't really try it out. I don't want to screw with the ducting too much. I only hope to connect it once right...


Also I forgot to order the clamp to connect the filter to the fan. crybaby.gif Do I need it at all though?
The RUCK plugs nicely into the Rhino. Could I just seal it with duct tape maybe?
