DIY Inline Carbon Filter Plans

specialkayme mentioned a link in a previous post of mine to point to a DIY carbon filter that is pretty nice...International Cannagraphic Magazine Forums - DIY pro style carbon filter ... He also mentioned he couldn't find any plans for an INLINE carbon filter... so again at work today I was bored and thought I would draw something up using stuff you can find at lowes.

The picture should be self explanatory and I don't really feel like labeling and calling out everything but..

1.) the Grey lines are a screen wrapped around chicken fence or panty hose over some chicken fence

2.) the first picture is the actual Filter assembly.. I think the smallest this would work with is a 4" to 2" reducer (unless you find smaller), 4" end cap, 2" end cap (this will give you 1" space around for carbon rocks).. Use sheet metal screws to screw the caps together on the end (Shown in picture 2)

3.) the second picture is the housing. in this example I would have: 2 - 4" to 6" increasers, and a 6" piece of ducting to however long your making this thing. I show a cross section view of the assemble with screws placed where they should be. Since the spot to fill carbon will be 1" thick, I used 1" long screws in four spots around the outside housing to hold the inner filter centered.

Make sure to wrap the filter with something so carbon doesnt get everywhere... 4" Inline Carbon Filter... This can be increased in size also. Happy Growing

Wow, I'm actually impressed. Not only did you mention a post I made, but it inspired you to create an interly different thread, and design something completly different. Very interesting. Next question, of course, is does it work? Would you like to try the construction or would you like me to?

I don't necessarily need an inline air filter but I know it will work. I just made one like my other plans and it is working great. I don't see any reason why this wouldn't work after making the Carbon filter I just made. The most expensive thing is the Chicken Fence but if you got left over the other stuff will only cost about $30 bucks... I wrapped mine in the Carbone Filter replacement pads for air purifiers found at lowe's for $10. If I get around to it tonight I will post a pic of the filter I made... I just got my 400 hps today so I will probably be hooking my diy cooltube up and getting that all setup. If you want to try this out, go for it- I am 100% sure it will work... you MAY have to buy 1 sleeve if the 4" part doesn't fit into the other 4" part very well but that would be the only reason why this wouldnt work... even so you could caulk or stuff padding in there to keep the carbon from slipping. Good luck man
