Ventilation Duct Fan For COOLTUBE Question

[GaGrown]

It powerful enough to do the task! Just hook it to the timer with the light and let it come on with the light and go off with the light!

You think so? Here's the kit I bought today:
SL TD160 In Line Fan Kit

Will that do?

Air Movement
Speed 1
160m3/hr - 2500rpm - 35watts

Speed 2
130m3/hr< - 2100rpm - 23watts

if i did the calculation rght the fan you got is about 91cfm at the high speed. that is about the same as the fan i 1st tried to use with my 400hps before i upgraded. as i said it works but not as good as a cooltube should with a more powerful fan on it. i got through a grow with it without problem before i upgraded. this is what i upgraded to it's only 15bucks more than the 1 you linked. Ecoplus 465 CFM Industrial Grade Blower - Plantlighting Hydroponics

i just noticed that your in denmark, i guess the prices on your link weren't in us dollars so the price of the fan i linked is 80us dollars and the one you linked is 64euros i guess, i don't know what you guys use for cash over thee or what it equals in us dollars, please forgive my ignorance, i'm just a stupid american unfortunately, lol.

OK, thanks. How well will it work if I just want to vent the room? No cooltube?

If your gonna vent the space your using then a 265 or a 465 will work best for you! If you are gonna vent the tube? Then have it blowing ant the mogul end and exiting via a duct.The shorter the better!If it's flex then pull it tight! Less restriction that way.I use a 265 and a tempstat by my light hood and it only runs for about 5 mins. tops! I have a fairly large space,too! I'm about to post a pic for ya!

Cool thanks. I should mention I also have one of these sucking in cool air at the bottom, its either 60 or 90m³/h

FAN.........

Btw, both holes are done and puttied. Drying till tomorrow, fresh coat of matte white tomorrow for the next grow

All you need is an entrance for air! Don't really need a fan blowing in as long as you have a fan blowing air about the room!It'll save ya some on the electricity bill.
