i have an 8inch vortex fan and 6 1000w raptors and i was wondering if i should have the fan blowing the air out of sucking it out?

Sucking the air out.

depends where you want to mount your fan/blower. I tend to hang them outside the room in the ceiling by zip ties to reduce vibration noise to I set mine up to suck out the air. both work

Yeah I've just heard they are more efficient sucking air then blowing. Could be wrong thought.

That's a good idea with the zip ties. Mines just on 2x4s that r insulated with foam to reduce noise but zip ties might be ever better. Might have to try it out

That 8inch might not be enough to cool 6x1000w lights,


Are they all linked in one straight line? This would give the least resistance.



Personally i would have 3x1000w per 8inch fan. 2 fans running 3lights each.

its easier to push air than to pull air

Some fans do better pulling air some do better pushing. If your worried you could use 2 of the same fans 1 pushing and 1 pulling.

Pulling is more efficient, however, with the lights and everything else in the way it may be better to push over the tips of the bulbs. With 6 lights, it might actually be benifical to have a duct booster fan in the middle of the chain

tell you what, a lot of "centrifugal fans are refered to as "blowers." I am wondering a similar issue. I have a 20 foot run on my fresh air supply and I dont know if I want my fan to pull the air or push it...

pulling is ideal, but that fan is not strong enough for 6 lights you need another fan atleast 1 8" per 3 hoods is ok i like 1 per 2 hoods though lol cool glass

thanks for all the replies. i have the 8inch vortex fan if that makes a difference. there is some turning but its not 90 degrees i was gonna try to have it pull it out but i could do both i guess.
