Im curious as to what size (cfm) fan i should use for my current setup.
im using a 4x2x8 closet. im only using 1 extractor fan on my cooltube atm which does the trick as it runs in a straight line and sucks air out of the room... BUT!!! i want to now run ducting from my ceiling down about 2-3 ft then onto the cooltube then back up near the ceiling and exited through an exhaust fan into a neighbouring closet. this whole run will only take up about 3-4 meter's of ducting at most. i wish to use 4inch/100mm ducting on my cooltube which is 6inch/150mm (i have the reducers).
what size exhaust fan should i use?
should i have it as an intake or extractor?
any help if much appreciated.... tyvm![Mr. Green :mrgreen: :mrgreen:](/styles/smilies/icon_mrgreen.gif)
