I've got about 3 of them (I believe they're cheaper at homedepot.com). IMO, the only good thing about them is that they're cheap. Their air pressure goes down drastically with the slightest bit of resistance. They also get unbalanced and noisy. But I have used them to cool lights, scrub air and also cool a res through evaporation.
My main fan is now an Elicent centrifugal fan and it's powerful, quiet...a real precision piece of machinery. But it's 10X the price of the Suncourt.

Don't pay 40$! You can get them MUCH cheaper just about anywhere! My hydro store even sells them for about 26$. I agree with OG... they're not even close to 250cfm once you add the slightest resistance. [I have 5" computer fans that push more air than this thing. I use one on the aircooled hood and it works just fine for that but its not much good for anything else except just air circulation. Won't even come close to running a carbon filter.

they are good for bringin in fresh air and for light venting. if you use them for your lights you really shoukd buy 2 of them and set up a push-pull venting. any turns in ducting drastically reduces their cfm. if you use one for intake air you can reduce your square inches of passive intake by quite a bit. they are very quiet and easy to install also.

Thats prolly what im gona do. I have 465 pulling through a squirell cage which i have found to not quite do the job on 400W...I know that sounds outrageous but the fan rating is actually based on the push from the out put rather than the pull from the "input" which is only sucking about half the air from its hole and the other half from the unsealed motor oriface....LAME.
I really need a cetrifugal vortex but i am soooooo not in the position financially...
Thanks guys,

squirrelcages sound like lawnmowers...
When you get the $$, grab an ELICENT!! I got a buddy who been running one for 9 years straight!!

Those are duct booster fans. I have the Suncourt 6" and it's a piece of shit. It moves a decent amount of air but it's really loud. My Vortex which moves far more air isn't as loud as the Suncourt. Also it's only 250cfm if using it as a booster. By itself it only moves like ~50cfm. If you goto Home Depot and look at one it says on the back how many cfms it does by itself. It's also a lot cheaper at Home Depot than that site. And like said it will not work well with back pressure, so don't try putting a scrubber on it.
With vent fans you get what you pay for.

Theyre about $30 @ homedepot, but dont be fooled by the 250cfm rating. That 250cfm rating is the "boosted" rating, meaning that it needs to be inline with another fan to reach that rating. The real speed of that fan is 160cfm, and thats with out any air restriction. Its also pretty loud; i belive its 50dba in terms of noise level. A 6" 449cfm vortex is quieter with noise level of just 49dba.
It seems like you were willing to dish out $40 for this duct fan, but i recommend you modify a stanley blower which costs $50 total: http://www.icmag.com/ic/showthread.php?t=29341
Or better yet spend the money for a 265cfm dayton... You can get it used on ebay for about $50. Used or new the dayton is one of the most reliable blowers that money can buy.

Yea man those things suck for the most part. What you have there is simple HVAC duct booster fan. Great for moving 250 CFM of air with ZERO static pressure. That mean no turns or curves or ridges in the pipe and no air resistance on either end of the duct. So like a straight piece of smooth duct would be perfect for this booster fan.
This is an axial fan. Much like the fans cooling your PC or a box fan you put in the window. If you where to close the window behind your box fan it would be forced to suck air through the smaller opening of the window and it's performance would drop off drastically. Axial fans cannot perform where you have pressure or resistance in the venting scheme.
To move air through ducts well, through air cooled lights, through carbon scrubbers and then through more ducts you need centrifugal fans. I prefer the inline kind, but either way to get any reasonable performance in cooling anything 400 watts or more you'll want centrifugal fans. Unlike the wide bladed axial fans centrifugal fans move the air move with a scooping effect. This applies much more force to the air which is called air pressure and then air then pushes its way through most anything. A centrifugal fan in say a cabinet will suck air aggressively through every intake and crack even pulling the door of the cabinet shut and it does so much more efficiently than an axial fan which would have to be MUCH larger, and higher wattage to get the same pressure.
For moving air in open areas axial fans are ideal and very effecient. A 60 dollar axial fan in your living room window or an attic fan moves an amazing amount of total CFM, but close the windows most of the way and your air movement dies.
For growing you will usually need to send air through ducts and carbon filters so centrifugal blowers are ideal if not required for most people. Vortex makes great inline fans with 10 year warranties last I checked. They are effecient, quiet (for a blower), and much easier to install than dayton blowers. Inline blower are the way to go. mdhydro.com has them pretty cheap last I checked.
Soo that booster fan is only good for open areas and relatively short duct with very few turns. It's good for micro grows.. but beyond that the uses are minimal for booster ducts for 35 bucks.. it's just a tiny tiny box fan in a circle. You could buy and take apart a cheap dollar store fan or such and potentially get more performance for much less. I think they are overpriced really even at 25 bucks... that's like 1/4 of the cost of a real fan.
You can get centrifugal blowers even cheaper, just look around. They sell em used and such. Perhaps ask electric supplies in the area for used or refurbished models, but be warned they will be noisier and less efficient than a Vortex. Also your houses HVAC system as built around a massive centrifugal fan and you might be able to tap that for some serious ventilation. I highly recommend running your air cooled light/room exhaust into your cold air return of your house. Makes ventilation much easier and avoids heat buildup in the adjacent room.

Pontiac how loud is the 265 daton? do u think it has enough power to push through a 6x18 8lb carbon filter? i was planning on doing it with the stanley blower mod, but if i can get a dayton for $50 i would do that fur shur.
Thanks for the info,

what do you guys think is the better choice the stanley blower mod or a hydrofarm 265??
NK- Yea, i'm using a very tiny 4" x 10" carbon filter and i still get very good air movement with my used 265 cfm dayton (note- that the dayton was used in high temp furnace applications for a few years). I know for sure that there wouldnt be ANY air movement if i was using that inline duct fan, cus my filter is so damn small. The filter youre describing is pretty big so the dayton should do just fine when pushing through.
