Well, after reading this my head was spinning and I decided it is way too complicated and expensive to pursue CO2. I think I need to take some Advil my head hurts so much. Great write up though and for those that are interested enough and have the cash and technical skill it is on point. Now off to get some meds for this headache. I think any even slight inclination to try CO2 was put to bed after this.

Oh c'mon, it wasn't that bad.

LOL

Yes it was! And for reference I crunch numbers and create dashboard reports and analyze data for a living. LOL

No problem. Just let oldpunk sell you a setup and put it all together for you. Then all you need to do is install it on your own CO2 tank and drop a good diffuser into your tank.

Not much harder than playing with Lego blocks, only you use wrenches to hook 'em together.

Does anyone know if the Clippard ET-2M-24-H will work? It's listed as low pressure, high flow (hence the H.) There is also an L version (low flow.) The regular ET-2M-24 that everyone seems to use says neither on the Clippard site. Thoughts??

**oldpunk78** · 01-09-2012, 10:00 PM

They just have different orifice sizes. The 'L' version is actually the medium flow model and the ET-2M-24 is the lower flow model. The ET-2M-24, ET-2M-24-L and ET-2M-24-H will all work.

**kevmo911** · 01-09-2012, 10:28 PM

Even with with pressure set to 30+psi (which would be necessary for an Atomic-style diffuser), the -H model will *probably* work, but it's only rated to 25psi. The standard and -L models are rated to 105 and 50psi, respectively. For some reason the info at Clippard.com doesn't show this, but if you click the link to the catalog page, you'll see it at the bottom of the page.

Be aware that those are mounted versions, so in case you're checking Evilbay and not the Clippard site, you'll still have to order a mount from Clippard, in which case you're better off buying straight from them. There's no price difference between the standard, -L, and -H, so just get the standard. An example of an inline (not mounted version) would be ET-2-24 rather than ET-2M-24. The main advantage to a mount, for our purposes, is that the inlet is 1/8" NPT, so it's a bit sturdier than a non-mounted version, which has a 10-32 inlet.

^ I'm glad you helped here. I just looked it up on Clippard's site and thought that the 105spi rating for all three looked weird. Now I remember why. There are actually a bunch of typos like this on their site. I should have remembered.

maduro80 · 01-09-2012, 11:41 PM

Thanks, that clears that up nicely. Just wanted to know the difference before ordering.

Often when you get one of these 2 stage regulators there is a manual shut off valve on the low pressure side already installed.

Pretty well every build thread I have seen... it is absent. Anyone leave it on, and just build off of that with thier solenoid and needle valve etc...?

**oldpunk78** · 01-15-2012, 04:44 PM

There's no reason you can't leave it on. I remove them because its just an unnecessary part. It might be useful if you don't have a solenoid.

Ok cool - just kinda figured it would be handy to have a cutoff for those "What if" moments LOL...

the 212 look really nice, here is a couple pictures of the build

and good news to you who want a quality setup, oldpunk is getting ready back to business again.

I am not be able to take any new orders recently, due to busy personal working schedule, work almost 70 hours every week and barely have time to stay home. So I contacted oldpunk and wanted him back to the business so he could build setups for the fellow hobbyists, got negative answer initially but now he just contact me, and he is ready.

Nice informal thread.
