inline fan to cool 1000 watt under $175 total?

I've asked this same Q: i have a 400w hps that's in a cool tube , i use a 100cfm duct boosting fan its works ok my thoughts would be just the light no filters a 250cfm should cool the 1000k light ,i may be way off lets hear from some of you out there with 1000k watt lights ,a little help please ....rob
 
Yeah I plan on using a filter but if I have to I can add a booster. I'm using a sealed hood, How cool does it keep yours? Thanks for the reply
 
I know this is too late....but for other people who have problems with this, you might wanna check out amazon. I got all my inline fans from there and they work great BUT..........the 200CFM is not enough for a 1000w if you're using carbon filter in a 4x4 tent. I tried to limit my bends and turns in my ducting to avoid suction loss and it still get to 84degrees in there. I would recommend a 400cfm fan if you are trying to cool down tube and also suck air through a filter. And make sure you exhaust that hot air outside and not into the room because it would only get sucked back in through vents and you will have an 80 degree temps going into it. this it the one i bought http://www.amazon.com/LED-Wholesalers-GYO2402-Hydroponic-Booster/dp/B003YFADW8/ref=sr_1_1?ie=UTF8&qid=1334181393&sr=8-1

And here is a 440cfm one for $89 bucks http://www.amazon.com/Hydrofarm-Act...14F8/ref=sr_1_2?ie=UTF8&qid=1334181393&sr=8-2

Remember though too much of a suction in the tent will suck out too much co2 if you're using that set up.
 
go for a 6" vortex. they are extremely quiet and long lasting. i used one to cool 2 1ks withno problem. plantlightinghydroponics.com has them for $139
