Backyard gas vent filter
 

Needed to vent tank and this is how I did it.
Carbon filter material
Some activated carbon from local pet shop
Co2 cilynder
Micro filter
2x 1/4" bungs
Aluminum tubing ( placed some carbon mesh inside ) to prevent clogs
Line going to tank is isolated from loose carbon.
Access on top to replace carbon if needed
Will put a safety valve on the line

Very cool. I was going to build myself a couple. Did you cut the C02 tank in two pieces and weld it back together?

Yes it got cut and shortened by 4"

Well that beats my solution which was to give the vent line a couple of loops and then zip tying some pantyhose on the end.

That was plan B

Excuse my lack of knowledge but my curiousity is killing me, what exactly is this used for and where? Is this like a home made version of the II Much fuel vent?

Yes it's the " NOT MUCH "vent

LOL ^^^ ok

:idea: I Like It ! Nice idea.

Thanks Wayne .
It's now official it works . It's been in and out of garage ( 3/4 full tank ) with close to 100 dg temps and not a hint of fumes in garage.

Here's an alternative to cutting up a C02 cylinder for those that might not have access to a lathe or welder. This is sold as an oil catch can but, because it has a removable top, it could easily be converted to a vapor trap using the same method as above and at less than $30 it won't break the bank. These are available in Red, Blue, Black and natural aluminum.
