Dayton is considered good, Vortex is best IMO and relatively quiet, CanFan is very good. Compare warranties. 265 cfm sounds good unless you are going through several turns. Always use straight duct (actual ducting) instead of dryer duct whenever possible. It makes a huge difference. If you add a muffler or carbon scrubber increase the CFM. How much? x amount.
Opie Yutts Reviewed by Opie Yutts on . 400w HPS - can't decide on fan Hey all, my cab is 2' x 3' x 6' and is separated into two chambers... one flower one veg. The veg chamber has an array of veg spectrum CFLs (6x27w) and is 26" tall, the flower chamber has a Hydrofarm 400w aircooled HPS setup (reflector w/ glass, ballast etc). The reflector has a 4" hookup, which currently has drier vent hooked up to it going up into my equipment chamber. I have some activated carbon I bought and can make a filter pretty much any size I want. I want a fan that will cool this Rating: 5
