inline fan for 400w cooltube

canadian said:

This is a noob question... but I have to say it,

I was researching my potential 400w perpetual cabinet grow and I stumbled apon a cheap 6" Aero Flo 240 HIGH CFMs inline Duct Air Booster Fan http://cgi.ebay.ca/6-Aero-Flo-240-HIGH-CFMs-inline-Duct-Air-Booster-Fan-/330351699650?cmd=ViewItem&pt=Air_Conditioner&hash=item4cea7ee6c2#ht_7683wt_1253[/HTML]
Since this is cheaper than a, say a vortex inline fan, can this be used to cool a 400w cooltube. or do I need a true inline fan with a higher cfm? (assuming that I attach a carbon filter to the fan)

Could someone clarify to me whats the difference between a air booster fan and an inline fan? And would someone clarify if the air booster fan will be enough for a 400w hps cool tube (with carbon filter)

dude i have a 125 cfm 6" duct fan to cool off my 400w hps (well 2 i should say) and i can still get the light 6 inches from the canopy with no problems. the combined cost was 55 dollars. You should see if you can get that 400w going...

Alright thank you for your guys feedback. I found a nice 6" inline fan (vortex) for $104 (shipping/handling) so I think that is my best bet. I've also decided to use a 250 cool tube hps instead of 400w... so I know this inline fan WILL control the heat!

CFM of 350 http://cgi.ebay.ca/NEW-Duct-Metal-Fan-Inline-Exhaust-Fan-Blower-Vortex-6-/160431466337?cmd=ViewItem&pt=LH_DefaultDomain_0&hash=item255a75e761

Will the 250 air booster vs vortex 350 make a huge difference when cooling a 250w hps? I heard air boosters are bad with bends in ducts too.

The boosters are used for long runs. That fan will cool a 400w with a carbon filter included.
