Ok, so I'm trying to decide on the right exhaust fan for my setup (2.5' x 5' x 7').. I was wondering if any vets had some advice to give me on which type of fan I should buy.. until recently I was just going by cfm ratings, but those can be misleading.. I'm going to have the exhaust be linear to reduce any air restrictions, and ideally, have 8" duct tubing going to a wall mounted register.. here's what I'm looking at now
8 In. 110VAC 500FM In-Line Duct Fan - 3012 at The Home Depot
..but for some reason, it doesn't seem like this could do the job that a can-fan of the same size and lower cfm rating could do... squirrel cage alike.. are cfm ratings always what they seem?? what should i do?
also, there will be a scrubber the air needs to pass through as well, and it will be connected to a cool tube as well
PS Im broke..
thanks
