About carbon scrubbers

[totalgearhead]

Hey guys
Check this out.This thing got me thinking.
I was looking for a scrubber and found one on www.leafman.nl
I found one big enough for me-250 cubic meters.
Then,when I look at the spesc. it says this:

''Always make sure that the capacity of the chosen carbon filter is higher than the capacity of the used sucktion fan !!! ''

I allready have an 4'' inline fan rated at 155(min)-200(max) cubic meters.The fan has 2 speeds.
Now I don't know what to do.Should I get a new fan,larger than this one?

i think you should be fine. it seems to be saying that you always want the cfm rating of your fan (how much air it can move) to be less than the cfm rating of the carbon filter (how much air can move through it per minute). that way the fan is not overly stressed. so pretty much with a 250cubic meter per minute filter and a 200 cubic meter per minute fan, you're good to go because your fan has less air movement capacity than your carbon filter

Thanx for saving my skin Irish
For a moment there,I was scared as hell.
Before I read that info I was about to buy a scrubber at 125cm.Man,what mistake I could have done.
Huh. Reading is so damn good.

I have one more question that' eating me in: my ''micro'' friend wants to know if he can cool a 250W HPS cooltube using 2x 120mm computer fans(one pushing and one pulling air).From what he told me his cab is 2x2x5ft.

if i used a fan on a speed controller and set it higher than what my can filter is rated for, would the odor particles wizz through the filter and stink up the place or are you positive the filter would limit the air flow to filterable levels?

I have a 260cfm 6" inline fan and the can 33 which is rated for 200cfm. this should be good to filter and ventilate a 1kw, eh?

St0n3r I belive (from what I've read so far) that if you exceed the scrubber's capacity with your fan,the stinky air won't have enough time to come in contact with the carbon particles.Like you said the odor particles will wizz through it.

I think I got like 20 calls from my buddy

Try using pinesol in a waterfountian, of bubbler. It will remove all odors, even better than the scrubber. Use the fan to ventilate the light. I promise , you will be suprised here. Mine were real stinkers too.

Sill I don't know what to tell my friend about his setup.
I need an answer asap.

Hello!!!
Anybody ?

If he has a fan taking air out of his setup it should be fine, but if not hook those fans up at the back of the box pulling air out and put a little desk fan in there for circulation...
You need to remove the heat from the box not just spread it around by blowing across it....
Hope this helps..

i would get the biggest scrubber that would fit (but thats me!), or its extremely easy to make your own. in just thinking about it i think if you exceed the CFM of the scrubber it will either, a) lead to ineffective scrubbering, or b) just be inefficient use of the fan. set it up correctly and then you dont have to worry about those.... as irishsoco indicated in his post, make the scrubber bigger than the fan needs... bigger means, better performance and less NOISE...

 

[totalgearhead]

Hey,thescissors the scrubber thing is set..I've ordered a 250cm/h filter for my 200cm/h fan.No worries.I think it solves my problem.

But that buddy of mine still doesn't know if his setup will work.I've told you,he wants to cool just the cooltube with those computer fans.Not the entire box.He's got a 250 hps bulb in a DIY cooltube.

 

[R00KIE]

Sry man, my bad I didn't see he had a cooltube, If I had to guess if they are big enough comp fans then he may be fine, but I would find a slightly more powerful fan and rig sumtin up, but thats just me...
Tell him to hook it all up and give it a try....
Turn on the fans and light and see how the temps get, if they stay reasonable then he should be fine...
Trial and error my man...

I forgot to mention that the fans are rated at 56,3cfm.
They look like this:

Totalgearhead,

Try the pinsol trick, it works. Just went through this myself last week. I have a 6 in. vortex and 15.5 in. x 22 inch carbonaire filter. It does not get all the smell out anyway. All odors are completly gone now.

The cool tube will need more than a computer fan. people use them, but you need moe air flow in a cool tube. The centrifical fan is neccessary to cool your light, lowering temps in your room.

I tested this last night. Turnned off the pinesol bubbler, and within minutes it began to stink up again. Turned it back on, they were completely gone. Plus, this is a cheap fix for both your problems. You cant mess around while odors might be detected by others. Just opening your front door, people will spell it. You will get riped off, or busted.

I am not familliar with the pinesol.Sorry
I'll stick to my carbon filter,after all my cab is not big - 20x20x50''.
My setup is scrubber->fan->cooltube->out.I have found this style is used by some people here with success.

So,afterall, my buddy can't cool that lamp with 2 of these fans,uh?
I'm gonna tell him to find a bigger fan (prolly. something rated at higher cfm's).

Just ordered a scrubber today for my micro

Just ordered a scrubber today for my micro

Hello , just thought I would add this info. I just ordered a Can Fan Filter fan combo. CF9000 w/RS5HO fan 5.5"x25"filter; 5" 206 cfm fan.
I asked shop keep this morning about what you had read. He told me the filter slows the CFM to almost half. Sometimes even more depending on the filter. Can-Fan combo spec's I copied are-MAX CFM: Recirculating (Scrubbing): 136/400 m³/h Exhaust: 118/200 m³/h @ 0.1 sec contact time RS5 HO

Specifications for fan RS5HO are CFM: 206@0wg
Recommend Combo:
FAN Filtered CFM
RS5HO 109
So the way I am taking it, if you are cooling & scrubbing w/same fan to get approx double the CFM the filter is rated for. I have 36 CUFT to cool & scrubb. Need to multiply area x 3 to get good cooling & scrubbing. I am using T5's so doesn't take much to keep cool. I am mainly trying to destink-a-fi
I will try the pinesol bubbler too. Double protection can't hurt. I am thinking to run the scrubber set up on the same timer as the light. Then just let the pinesol go 24/7. I hope this helps.
Ps. check www.canfilters.com they have a reference on the pages that show CFM of filtered air.

 

[totalgearhead]

So you are saying that if I have a carbon filter at 250cm/h then I should get a fan rated at ~500cm/h?
That just don't makes sense.
I belive that my fan has enough power to cool my light after it has pulled through the scrubber.Just my opp.

Wow,I really like that combo stuff.Real nice.How much did you paid for it?

 

[The Dopest]

hey Gearhead, tell your friend that what may work for one person may not work for another. its hard to say if those will work for him but they could work. its best to over shoot though and if he has room, i would recommend a stanley fan. you can look in my sig for a few different ideas.

sounds like you did the right thing with the filter, gl

 

[totalgearhead]

Nah man,his cab is very simillar to mine.Except he has no scrubber an only wants to cool his 250W cooltube.Plus,he's in some financial bog right now.

I have a different setup:scrubber->fan->cooltube->out.But,hey,I managed to save some money from my ex-job for this grow.Now I got myself a new job and allready saving for a biger room
