Will a 500cfm Inline Fan Cool 2 600w HPS??

what's the point of the carbon filters? filters are to reduce odor, you want to put those on your exhaust air for your room, the air for the lights is just to cool and should be seperate from the room.

My bad, I should of explained it better, the 500cfm fan from tha "tee" conneting tha 2 lights will be connected to an insulated duct venting tha air out of the room.

Should tha 500cfm cool both lights??

500 cfm is no joke.. i dont see why those wouldnt work... whats ur temps like?? I think thats a good system
 
I like your idea....I'm currently working on my exhaust system aswell, but only need to cool one 600w hps.

Just to clarify, your fan will be pulling air through 2 filters across the lights, as well as exhausting the room's air from the second "T" connection?

I think you need to check the static pressure of the fan.

The inline duct fans are created to be placed.... inline... it probably will work but not even close to the full potential that it would if it was inline. why not put them like this -----/hood\----/hood\--(fan)

I would like to see how this turns out. a 500 cfm pulling thru 2 carbon filters. And the Hoods.

I am curious as to the size of your grow area.
I agree with PurrrrP, Inline you will have less restriction on the overall cfm.
Being personally not opposed to having the filter(s) inside (some people just can't have them outside the grow.)
I wonder how this would work.

(oooooooo) Filter
0
0
000000000/Hood-----Hood---Fan.

I am not good at drawing with the keys but.
Maybe the Filter positioned above a hood, then inline to the next hood. then FAN to your 6" exhaust tubing, and out the grow area.

My thoughts are Maybe 2 filters will slow air current? will 2 bends greater than 60 Degrees slow current.
How much CFM will be left after pulling thru 2 carbon filters?

A ton of people will say never vent your lights with air from the grow area "Just makes things that hottter"
"Like forcing hot air into a hairdryer, This will only make things hotter." thats what I keep hearing.

I don't have a problem and as the weather outside changes I don't think that will end up being a problem for me.

My next and final mandatory purchase is a filter. So again I am interested to see how this turns out, what you end up doing and how the performance is.

so you have gotten it from all angles
some say it should werk, some say, don't restrict the airflow to the hood. some say, Place hoods inline.
Seems like everyone is trying to help. Keep it simple, try not to slow air flow, we are all watching!

my opinion is that it should work fine set up like that granted you have a good enough intake.. im not real sure of the tee tho might want to get a "Y" for better air flow..

if possible connecting a single duct through them inline with a filter on the beginning would be cheaper/more efficient. Also, you could have the 2 ducts connect into a t again and have 1 carbon filter attached there. Let's say you have an 8"inline fan, then Y splitting 1 8"duct into 2 6" (1 to each light) then another Y connecting the 2 6" to an 8" then to 8" carbon filter. You could keep them all the same size to make it easier, it's just more efficient this way.

Simplest thing to do is line them up, put 1 duct through them and a carbon filter at the end.

I use a 300 cfm fan with a 250 cfm inductor fan, run through four 600w lamps and a filter. My temps are fine and I can touch my tubes, and that's with tons of flex-duct and bends. You ought to be fine with two lights. Save yourself money though and just use one adequately-sized filter.
