I am in the process of designing a 400 watt grow cabinet, and I've got a couple questions.
I am planning to use an Elicent inline fan to suck through a DIY carbon filter, through a 6" (probably Hydrofarm) cool tube, and blow out of the cabinet. I found the spec table for the Elicent fans. It gives flow rate (in m3/hr) versus pressure (in pa). This information would be priceless if I only knew how much static pressure would be generated by my DIY carbon scrubber... The only static pressure numbers I have been able to find are on the Can Filter webpage. They list static pressures at "max CFM" for a couple of their filters (not all of them...). The two they list are 0.75" water for the Can 33, and something like 0.375" water for the Can 2600. My DIY carbon filter will have a bed thickness of 1", which I think is closer to the Can 2600 (but the 2600 is a 4" model...).
So... Could you guys throw out some guesses on what the static pressure through my DIY carbon scrubber will be? I am going to use a 6" inside diameter, 8" outside diameter, and about 15" long.
