i have two 6" 400cfm inline fans and need advice on how to most efficiently mount them.
currently, the flow looks like this: carbon filter >> duct >> 6" fan >> duct >> air-cooled reflector with 600watt HPS >> 2nd air-cooled reflector with 600watt HPS >> duct >> vertical 8" cool tube with two 600watt HPS >> duct >> 6" fan >> duct >> another carbon filter (as a backup for when the first one gets spent).
this setup does not seem efficient. pressure builds just ahead of the first fan in the reflectors and leaks out small gaps in the glass seal at the corners. seems like the room runs cooler when just the one fan closer to the exhaust is on.
the horizontally mounted air-cooled reflectors are both on while the vertical cool tube and its two 600watt bulbs haven't been fired up at this time.
would i be better off putting the two fans closer together toward the exhaust end of the duct so they're working together to pull the air? is there any benefit to having two pulling on the same intake? i'm assuming that'll get me closer to 400cfm actual flow.
alternatively, i could split the two setups and run one fan for each pair of 600watt HPS bulbs. but that would require another carbon filter and another hole in the ceiling for exhaust.
any ideas?
