Can't find the right duct!!

Guys, I don't know what to do and it's giving me a panic attack. Every duct I've tried for my air cooled lights so far won't work. Aluminum ducting has a ton of tiny holes in it that will leak smell. Insulated ducting is too thick to bend in the ways I need it to. Woodworking dust hose is too small in diameter. If I run aluminum hose but with the air pushing through the hose instead of pulling, would it not make smell leak?

Your fan has to be at the end, so your pulling air rather than pushing.
If you pull air, and it passes though the filter at the end there is no smell.

ok smerked out

the little tiny holes are nothing when u are moving 240 cfms /170 cfms/400 cfms/720 cfms

once the air passes over the carbon filter it is clean no smell so that is the not the issue .....i tell ppl to think of air like water cold water sinks hot rises they both have a flow path water u see .......your ducting u want as strait as possible with as few bends as possible .........and when u put the ducting out u want to stretch it all the way out no ridges of extra ducting

to do what u want to do the inside tent has to be the flexie ducting just for the bends then to the fan flexie ducting then off the fan PVC piping

But I'm running my lights with their own fan separate from the filters. So I'm drawing cold air in through a duct, into the hood, out of the hood, into the next tent, through that hood, and out. No filter on that line. So any leak will go straight into the open...

Then add a carbon filter to the end of that line.

carbon filter is always the first in the line hung at the top of the tent ....so it removes the hotest air from the tent

carbon filter....ducting......hood with light ....ducting ......fan......ducting/pvc....ejection point with a vent

I agree with you justugh, but he's running two tents together so adding a carbon filter to the end would fix his problem.
If it were me, I would have a separate system for each tent.

But if I do that, and then the duct has a ton of little holes in it all those holes will suck in unfiltered smelly air.

Take your aluminum duct, block one end, and use your hands to seal the other end to your face. You'll see that the duct is FULL of holes.

no
the air is passing to fast to really come in tho those ......air will always travel the path of least energy
(given this the carbon filter is matched to the fan so the path is always tho the filter) the only time it would possiblly pull tho those is if the carbon filter was to small or is blocked off somehow with something

But the path of least resistance is those holes. The filter is further away from the fan, plus it has carbon that the air has to go through. So it's easier for the air to go through that hole than go through an extra 2 ft of duct and a bed of carbon.

try it light a smoke and blow

aslong as the filter is matched to the fan the smoke should not be pulled in and if done right it should be blowen away with in 10 secs of being blown

the only answer u seem to be willing to accept is PVC pipping .........this is going to massive increase the weight on your system so unless u are a gorilla tent u have alot of work to do to build a support system and mounting system for the fans

if this system did not work thousands of us would have been busted on nearly a daily if not weekly scale

oh we all over looked air polishing
or if u are a 8 inch or 10 inch ducting adding in a ozone gen

Fuck I guess you're right on that last point... I guess I'll get some aluminum ducting. Or maybe some of this rubber coated stuff?

looks to be good never personally used it .........the only thing u might need to think of is it is BLACK so it will aborb heat from light .......all fans have a thermal senor on the motor it will cut off about 140 degrees

that and this is only 4 inches so that is only 170cfms
