Hi folks,
I'm planning on adding a nitro faucet to my kegerator and hook up a beer gas line to serve. Is there such a thing as a nitrogen regulator or can I use a "standard" one as I do for my CO²? I see Northern Brewer sells one (http://www.northernbrewer.com/nitrogen-regulator) but not sure if that is just fancy marketing lingo.

They are different. Some have told me that they have seen beergas in standard co2 cylinders, but I've only seen them in the nitro style.

Because the nitrogen gas in the beer gas mix requires being stored under greater pressure than co2, beer gas requires a high pressure tank and regulator.  Normally both the tank and regulator have a bigger diameter regulator connector and match-up connection nozzle than a co2 regulator/tank.  Also, the high pressure tanks have a female threaded connection nozzle, rather than the male thread connection nozzle of a co2 tank.

Apologies if I'm using the wrong descriptive terms, but I hope you get the picture.
