hey yasoob ,
gimme some more input . cooltubes ? air-cooled hoods ?
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

xcrispi Reviewed by xcrispi 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
