Inline Carbon Scrubber

[Guest]

For reasons of convenience I would like to design an inline carbon scrubber.

Is it possible to make one that won't overly restrict the airflow?

Any thoughts? Ideas?

Anyone? Ideas?

This could be handy in any garden.

Ive been thinking of using large diameter pvc and a series of couplers with screens inside. Lengths of pvc in between could be filled with activated carbon. Attach inline between hood and exhust fan with ducting.

Any help would be sincerely appreciated.

Hi phototropic.

Sounds like a good idea you have. Can makes an inline carbon filter. Have you ever seen the DIY carbon scrubber over at OG? I imagine with some pvc pipe and some reducers, your goal is easily attainable.

I was wondering why you wanted a inline scrubber. I take it your intake side of the hoosd is open and so you are exhausting stinky grow room air.

My hood's are sealed and supplied with fresh cold outside air that is than exhausted into the general home.

Now do not over restict the air flow as a large blower will be needed to pull the air thru all the carbon.

I have a larger fan that I expected it to be, does not fit inline a 4" duct, so I took box's of a larger size mounted the fan on side and on the opposite side connected the duct work from the hood. Now I call it an air box. It allow's enough room for the fan to be mounted and exhaust the hood's just fine.

Now a regular cardboard box is all I used, just tapped it up good so no air leak's. Now you could take a little longer box and slide in panel's of carbon filter every few inch's and this would allow air to flow better and reduce the odor. I would think 3 of them would do the job, so about a 8 to 10 inch long box.

If that is the only source of your odor and exhaust from the grow room, than yes I would put filter's on the end of the exhaust line.

Now if you have another exhaust blower for the grow room, well it is produceing odor also.

Maybe the Scrubber off of OG would be better setting it the grow room taking the odor away , but I do not see it helping with the light exhaust odor, inline or at the end of the line would be best.

Heck I will throw a carbon filter in my box's first to see what happen's. I am thinking of this pre made one's sold for home A/C unit's. The come in a few size's and are desinged to replace the exsisting filter that came with the A/C unit. Okay the model I have is this way.

Your idea is a solid one and will make it's way into the gardening world, so keep your idea rolling around, I hope some of my talk has helped you.

Just remember the more inline restriction you make the louder the exhaust blower will sound while pulling the air.

I really think you should think about this box idea. You can mount a large enough fan to pull the air thru the filter's, a nice surface to mount it to, and one could simply hot glue the filter's into place in the box, and actually make more back up filter box's and just remove and replace with a new one and throw old one away.

Thinking of my grow room and set up, well the only easy access for this would be at the end in the fan box's and not inline by the hood's exhaust port, again this is just my set up.

I really have to thank all for replying, as this only made me think a bit more, and now I have the answer to help insure no odor leak's out of my grow thru hood exhaust.

I am simply going to open the box, hot glue the carbon filter into place, close and tape box close, and I am in buisness.

Now I ran a scrubber as an exhaust blower, a commercial unit, and it is to small and air is not moved fast enough for the room, so I have to remove it and replace with a 465 cfm blower. Now one can pull the air thru the filter's or the can mount the fan at the start of the box and blow the air thru the filter.

There is a carbon inline filter, nope not inline, it is at the end of the line after the fan.
I seen it on a commercail grow chamber from canada. Just about a 3" metal chrome tube with holes and they have a carbon insert air must pass through first. I have only seen pictures of the grow unit, but a friend has one going right now, so soon I can ask them how the filter work's on odor control.

Think of how small your pvc coupled piece's are in dia., so filter pad's would be small, how much air is moving thru them, so how ofted do they need changed. I would think a few larger panel's of filter material in the box would serve the grower better control.

Again it will take only a few minute's for me to make a carbon filter box for my hood's, I just wish the room was full of stinky girl's, but we are a week late, so I will find out how the work with the next run.

stay safe and grow the same way, love the new idea's I have found on this site.

There is a thread at a site called UKCultivator.com there they have some how to guides, a guy on there showed how to use an old truck or bus air filter as the basis, then got some carbon, check it out.

 

[Guest]

Thank you all for your ideas. All great advise.

realhigh - THANK YOU! Your box idea is something i had not considered. It such a great idea, I will be making one to use for this application. I also have an oversized fan to work with, so your plan is even more ideal. Thanks very much for your post, Ill post some pics in a week or so when I get it built.

 

[Guest]

I would like to thank you phototropic and the other's.

I kinda got some control going, but not enough, and as I read the thread I thought, and Bamm this old fart got the idea thank's to the thread.

I hope you the best, and I will see how you do your's first as it might be better than my idea, LOL

grow safe.

I'll be interested in how your scrubber box turns out too, Phototropic. I'm going to need to come up with something similar for a new grow space I'm planning that'll have no outside exhaust. Thanks for the great instructions, realhigh!

Hey guys, the box filter is a great idea. Here's a few pics and a link to the original document. You'll need a .pdf viewer to view it which is why I've snapped them and posted them here for quickeness.

There are many way's to do this.

Another way is to purchase an Ionic machine. They do remove odor also and help kill mold spore's along with trapping loose pollen in the air. It also collects dust from the air and that is nice.

I hope you the best with your odor control.

grow safe.

Bump.
Why doesn't anyone ever do this?
Tell me why I shouldn't, seems like what I need.
Or do my search skills just suck tonight?

Because most people simply put the filter as either the first or last element in the exhaust chain, eliminating the need for an "in-line" carbon filter.

In a large room it works fine to put it first.
Inline would be best for smaller rooms that don't want to lose the space, or for venting more than 1 room through a single filter. Just seems odd more people don't do it, unless there is something obvious I'm just not seeing. I'm going to give it a try. My current fan should have plenty of power left over for the extra air resistance it may create. More resistance is the only negative reason I see.

Inline versions of a filter are larger than their corresponding non-inline versions. You basically have to take the non-inline version and wrap more ducting around it to make it "inline".

Can-Filter 66
Diameter: 12"
Height: 26"
Carbon Weight: 31 lbs
Carbon Bed Thickness: 2"


Can-Filter 66 Inline
Diameter: 14.6"
Height: 38.5"
Carbon Weight: 31 lbs
Carbon Bed Thickness: 2"

or for venting more than 1 room through a single filter.

You can always just put the filter as the last item on the end of the entire exhaust chain.

unless there is something obvious I'm just not seeing.

I'm just still not really seeing any advantage to "inline" versus regular filters.

It should work the same as any other carbon filter, which is usually pretty good.

Say wha? They took a standard end of line filter, built a box around it, doubled it's size ... How does that save space?

It can then be put outside of the room, obviously if you can leave it inside there is no need for the inline. I have (2) rooms that are both about 3ft x 4ft running vertical lights. The carbon filter takes up some space, and I hit my head on it quite a bit. I need to vent outside, so the filter can't be at the end. My duct runs through the crawlspace, so I have unlimited room down there to mount the filter.

Looks like people don't do it because it isn't usually necessary. I just wanted to make sure there wasn't some major problem with the air flow or something I just didn't see. Should have this built in a few days.
