air cooling \ ducting help

[jdubz206]

I am wanting to air cool my lights except I am having a few issues and hope you guys can help me out once again. Here's the rundown:
8" hydrofarm inline fan (568 cfm)
1 8 to 6" reducer
6" ducting
8" & 6" clamps

I have 2 hoods with 6" a/c cooling. I bought a cooling kit for a 3rd but didn't realize it was 4 ". I bought 6 to 4" reducers but was told that this will drastically decrease the performance of my fan, is this correct? Here's the other issue the 8 to 6 inch reducer doesn't fit on the fan. there's one edge that i can't get over. do you have to cut these things? do they never actually slide over and I just foil tape them to the fan? I don't want to scratch the shit out of the fan, which I've already started doing. Any help would be greatly appreciated. thanks!

Reducing diameters will definitely reduce performance. Wish I had a formula but ...

Consider cutting out the 4" flanges and replacing them with 6 inchers. You may want to convert all of them to 8. Of course, you'll have to enlarge the holes as well.

Will the 6" reducer fit on the hood? Then you could run 8" hose between that and the fan.

About connecting the reducer to the fan, I have noticed the same thing as they are both identical in size making it difficult to connect them. At Home Depot or Lowes you will find everything you need to connect the two. Just go take a look, they got so many - thats what I did and found exactly what I needed. Just remember to bring measurements. I always forget and they I end up buying a couple fittings that don't fit - always happens lol. Good luck!

How do I convert them all to 8?

do I connect the fan to 8" ducting and then connect that to the reducer?

man i am having issues with the shop up the street. i've had to return so much shit in the past two weeks because they keep giving me wrong parts or suggesting wrong equipment then I bring it home and realize they're idiots. just called them and they told me they only make 4" kits for the piece of shit reflector I have so it looks like I'll just by a new reflector. they have these cheap 6" a/c reflectors that I'll grab one of in the next few days. I'm setting up a new room this weekend but it doesn't look like I'll finish everything.


Thanks everyone for the help so far.

How do I convert them all to 8?

8" flanges. Short cylinders attached to flat plates. They come in various angles depending on where they attach to the hood.
Cut off offending flanges (or unscrew, depending) Cut out the hole to 8". Drill screw holes for each flange hole (use the flange as a jig) Attach the new 8" flanges.

nice thanks bro! i appreciate the help. i'm actually going to buy 2 radiant 8" a/c hoods and use them in my room. i'll still need to convert 1 light to a 8" so this will definitely help. any suggested place online to buy those pieces? they don't have those at the shops near me.

there dayton blower flanges, they have them at the hydro stores, never seen-em at home-de-pot. u could use the 4" for ur mother plants, only one reflector and a 4" fan itll work great. i dont know what to tell you about that shop, do some surfing at discounthydo.com and just look at all the things, plan it in your head and what u want it too function like when your done, and just part-and-piece your way to the dreamroom... i just get one controller or part at a time. but then again i kick it at my store the guys cool there, he even feeds me pizza and soda. just go in knowing what you want is all im getting to.

The flange in the pic above on the left is also called a "flat duct take off" at any wholesale duct supplier. They use them on rectangular duct systems to pull a round duct. They come in most any size. Good luck.
