Ducted window exhaust fans

[virginiadiver69]

I've been looking for some sort of DUCTED window exhaust fan.
What I have in mind is an in line duct fan connected to a window grill. That way I can vent hot air from my hood/stand to the window that sits directly behind my tank. I've some searching online but haven't seen anything...any ideas?

try grower fans, the type they use for growing pot, a few reefers (water) use them and they work great, I will be incorporating one in on my next build. I have seen cheap ones, thy dont have the cfm, buy a decent one that can really pull the air from the tank you can see them here http://www.botanical.com/hydro/air/canfan.html
