? about activated carbon

[Mr White]

High all

Am looking at making a carbon filter sort off to add to my extraction fans inside a small grow cupboard.

850x550x1750 of the top of my off head.

 

It consists of 2 x 120mm 240v fans running through 2 seperate lines of 125mm flexi vent into a 100mm two into one(y curved shape) pvc pipe and out the top right hand side.

 

My ? is ,would it be effective to mount the filter directly on the back of the fan with the air pushing through the filter or would it be best to mount it further down the line where the air flow is not that great and the air drifts through.

Not exactly sure what rating the fans are but im guessing they are about 108cfm

Or would it be better to suck the air through the filter.

Keep in mind each chamber will be loosely packed with carbon to let the air through resonablly well and i would expect it to blow around a bit.

 

Basically my ? is, would it matter if the air was forced though rather than drift through.

Not sure if it would work at all to be honest.

Hope it makes sense

Heya sycho , i think you should pack the carbon tight, not loose ... the air must pass thru the carbon particles to capture smells, also it should suck the air thru the filter rather than blow thru

 

have a look @ this https://cannabis.community.forums.ozstoners...showtopic=13508

good luck

Cheers Frazzle

have thought of a few ways of making this work and putting the carbon before the fan so it is sucked though it is the easiest one but wasn't sure so thanks frazzle i'm going to try that way first.

Bloody pearla that filter Blacksaint, Love home made projects.

xcellent idea,

Had my own little idea as well but when i seen the one een posted,i scrapped mine for now and gave this one a go with a few mods.

Carbon was the hardest thing to find,plenty at dive shops, but no one willing to sell.Persaverance paid of though.

As you see it is were i am at.

Finish painting it,put it together at see how this baby works tomorrow maybe.

Well she's done

and now only time will tell if it works,

About a layer of 15mm for the carbon and the 2x 120mm fans still push through a bit of air.

Plants not stinky yet so when they do i will find out how good it works

Top job sye , its a pearler

just kiddin ..

[Mr White]

Thanks frazzle

I reckon it cost me say $150 all up including the 2 fans at $40 each and the ducting at $25,

Definatley not enough on a day like we had today though,38+ where the cabinet is,aircon would be nice.
