Venting question

Recommended Posts

Morning guys,

 

I have a question relating to extraction fans for my grow cabinet. I've attached a pic of the cabinet I intend to use. 

 

The dimensions are as follows :

Height is 78cm

Length is 86cm

Width is 57cm

 

I've found this fan on bid or buy that I wanna use for extraction, is it strong enough? Or do I need more than 1? I'll be using 3 45w cfl's for now.

 

Fan spec :

AXIAL DC FAN

120x120x38mm

12V DC

BALL BEARING

3100RPM

138CFM   -    0.36"  H2O

48dBA

Any help would be appreciated!

I agree with GLO. I use 2 of those 220v 12cm ones. Just connect a plug and you good to go.

Hi bud

Well if ypu do the math your space works out to 13.502 cubic feet and if the fan does 87 cubic feet per m , let's rather call it 60 cubic feet per min as this will make up any margine of error , 60 divided by 13.5 gives us 4.444 . What this means is that your fan will extract the box 4 times a min or 280 times an hour which is more than enough.

Cheers
