I need a new exhaust fan that has a 6" inlet that is quiet (or as quiet as they get) and preferably variable speed. It needs to pull air through 6" cool tube, 2 elbows, a home made carbon scrubber and 8' of flex duct total. Does anyone know where I can get such a fan?
6" vortex 449cfm http://www.plantlightinghydroponics.com/vortex-inch-449-cfm-high-power-inline-fan-p-353.html 6" valuline 435cfm http://www.plantlightinghydroponics.com/valueline-inch-435-cfm-centrifugal-inline-fan-p-2260.html and if you want a speedcontroller http://www.plantlightinghydroponics.com/cap-variable-speed-fan-control-p-2263.html
I will try the Stanley blower mod. It does have 3 speed settings, so that will be a help. If I have little luck with that, I will get a pro model like newgrow linked me up to.
