Anyone use these fans?????

I've been planning a small grow tent, 2.5'x2.5'x5.5', using a 250w hps. But I need some help with the ventilation. Stealth is not of the highest importance, I just don't want it to sound like a jet engine taking off lol. Anyone know of any quiet inline fans. I found this one, http://www.ventingdirect.com/soler-and-palau-td-100x-4-100mm-inline-mixed-flow-duct-fan/p934766?intcmp=recs_cat_prodTD-100X_productPageWRatings3Items_placement1
But idk if anyone has used these models before and was wondering if anyone has experience. Or if perhaps someone can link me to a fan that isn't too loud or large, being a small tent I want to conserve space. Thanks RIU.

are you planning to use a carbon filter?

I got this fan it's not the quietest, but i've heard that others fans are way louder. There are many CFM ratings that can fit your needs sir.

Same company, similar design. At least it's not super loud. I was considering building a small box for the fan to sit in and line the box with acoustic foam, stuff is rather cheap

just buy bigger than you need, then buy a fan speed controller and turn it down half way or so, at half way speed you shouldn't be able to hear it. also acoustic/insulated ducting makes a huge difference.

What's a good CFM rating for exhaust fan in a 8' x 4' room?

depends on the height of your room, but a 6 inch 450 cfm should be good. its enough to cool 2x 600 hps down and the room.
