I upgraded my filter, and need to make my filtration setup more efficient. I was running a 6” kootenay filter hooked up to an old 6” eco line fan (440 cfm) to scrub my flower tent, and then having that exit the tent and run through my old/used carbon filter. The issue is, we have central air and my “lung room” is open. Any remaining smell gets picked up and blown throughout the house. I caved and bought a 12”x40” Can Fan Filter, paired with this fan :
My state is now legal and will allow more plants than I need, but I still value my privacy. I currently have 2 5x5 tents next to each other, with 6” vent holes. I’d like to run 2 - 6” “duct splitters”. One would mount above the tents, with ducting to suck/filter air from each tent - and then through the central fan and carbon filter. Another “t shaped duct splitter” would branch off with 2 additional lines, sucking up and filtering ambient air from 2 different ends of the room. I’m going to construct simple pre-filters to screen out any dust for each of these lines (as advised from can fan site when “blowing through the filter”). The idea is that I over purchased for my needs, so I might as well try and use it to its max potential.
I’m concerned with the possible back pressure on the fan with my intended setup, and overall load on the fan. The fan certainly has the power to do it, but I’m worried about the possible resistance from the length of ducting. Even though the tent holes are 6”, should I consider running 8” flexible ducting instead, and running it to a 6” reducer, to fit the tents? Other options would be: Turn down the fan speed (I have a fan speed controller), and/or put “relief holes” in the ducting to bring in more air and relieve pressure on the system.
Pics of: tents, fan, and some hardware store goodies - 12”-8” reducer, 12” connector flange for fan/reducer, connector flange for 6-8” reducer, 2 duct splitter pieces, ducting, hose clamps, strapping for mounting all ducting.
Thank you.
