OK, I'm planning on either buying a carbon filter/fan combo or just buying a new fan and making a DIY filter. When doing some online shopping or browsing pics of grow rooms, I notice that the filter is almost always attached directly to the fan.
One of the fan/filter combos I was looking at has a fan that's rated at 424 cfm and a filter that has a 265-424 optimal cfm range.
I figure a short section of ducting between the fan and filter would do a few things for me:
1. Because of static pressure, the fan would draw less than it's max 424 cfm at the filter, this would keep the air flowing through it around the middle of its optimal cfm rating which I assume would be ideal.
2. I need to vent my veg room with this fan as well so it needs to be behind my Y connector so I can draw from both rooms.
My question is this:
Can I run an ~8' section of ducting between my fan and filter and retain the filters effectiveness?
As I sit now, I have 2x 6" inline duct fans rated at 250 cfm. One sits behind the Y and one is boosting about 2/3 of the way to the final outlet out the chimney. They are definitely NOT great, but they do get the job done. It creates a negative pressure in my room but it could be better for sure. I just started 12/12 2 days ago and my room already wreaks like skunk and need to get this filter setup soon!
