i'm running 2 - 1000w. hps. inline in cooltubes w/ a pair of 630 cfm. hurricanes . 1 pushin , 1 pullin through the cooltubes which is probably way overkill but i have a cpl. sharp bends . i also run a fan speed controller and slow them down some . my 10 x 12 room is 72 degrees -n- you can lay your hands on the cooltubes for extended periods of time w/ fear of ever being burned . also only use as much of the flixable dryer duct as you absoultely have to , it reduces airflow drasticly . use metal galvanised stove pipe .
peace

cooltube 2k watt. i didn't upgrade the fan part yet. but yes, i'm getting a vortex brand for sure. I just wanted to check the cfm rate i need to cool 2k watt. I have to initial setup in mind.

1.) suck air in carbon filter-> 8" vortex -> 2k watt -> out the window

2.) suck air in carbon fitler -> 6" vortex -> out the window
suck room cool air -> 6" vortex -> 2k watt -> out the window

no point in burning money if i only need a 8"vortex to cool 2k watt instead of duel 6" vortex. Crispi, How loud does it get in your room with 3 fan ? oh and damn that one scary looking dog.
what is this cpl sharp bend? and doesn't the metal stove pipe have small hole for light leaks?
YASoob Reviewed by YASoob on . CFM backpressure i was reading this on another thread fans are tested without ducting which give them the cfm. The thread also mention that if you use ducting, it will cut the cfm by half. No one on that thread asked if it will cut more than half if ducting and carbon filter is use. It got me thinking since i just upgraded and i need a fan that will cool 2000watt in a 64 cubic feet room. Any input on this would be great. thanks in advance Rating: 5
