Help with fans

[MJ-XILE]

I need to get a couple good fans for my system. I have two 8" four port manifolds, one for intake, one for exhaust. I need a fan on each of these to move all of the air. I need at least two 800 cfm fans but could use up 1600 cfm, what are my best options as far as quiet goes? I'm more worried about the noise of the moving air as opposed to the fan itself, as I am facing a parking lot. Any suggestions?

Can you give us a little more information about your setup?

For one thing, it sounds like you have an equal intake and exhaust. If you are setting this up for a cabinet grow and want to control smell/cooling, then you are already going down the wrong track by having equal sized intake and exhaust.

In addition, 800CFM-1600CFM fans are going to produce a pretty good amount of noise unless you spend a good amount of money for a quiet one.

Are you using this fan for cooling, straight air movement, in a cabinet, in a grow room... there's a bunch of factors to consider.

If cooling, how much cooling? Information like that is useful when determining what fan(s) you need to get the job done correctly.

With a bit more detail about the situation, I'm sure you can get some good suggestions here.

Sorry about that. Room is 10x10x7.5, so 750 cubic feet. My room has a huge window that opens side to side its about 4.5x4x5. The room has a closet I am using for veg. I am planning a 3k light column with 2 hps, and one mh. I am using aero buckets, hydroton, and gh nutes. I have a great dual hose a/c for environment control as well. So, I am planning two separate manifolds to give me all the necessary ventilation. I am planning two 8'' manifolds with four ports each. One port for my column, one port for my a/c, one port for the veg closet, and one for my actual room (which again is 750 cubic feet) So i need some good fans to move this air, I figured at least 2 900 cfm fans, one per manifold. Here is a pic of my setup:

Go with the Comair Rotron Fans .The only one i use is the 550 cfm Caravel model p/n CL2T2 .But im sure they make the higher cfm ones as well,just research a bit .Industrial grade ,for a killer price.
