Does anyone use one of these? http://www.micromatic.com/draft-keg-beer/gas-equipment-pid-770SG-L1300.html I've seen a few pics of people's keezers with these things. They're kind of pricey but if it saves beer from bad CO2 it might be worth it.
I'm betting no one here has that filter. I'd be surprised if a reasonable substitute wasn't available for a lot less than $125.
no. it is not used. sometimes the soda guys use a filter. it is never used in any install I have seen though and we never use it either. not in our area at least. CO2 is food grade and there is no reason to believe it needs to be filtered. the gas is clean. never has anyone ever thought, "this beer needs a CO2 filter". also, it is worth noting that the description claims it filters "impure gases and oils" and that "the CO2 cylinder may not have been properly cleaned". if this is your problem you need a new gas supplier not a filter. @IceAce might have some insight. Cheers.
If you use paintball cartridges that contain lubricants, this might be of value. Likewise if you live in, e.g. India and the origins of your CO2 are suspect. In the reasonably developed world, purchasing from the usual welding gas/beverage suppliers, not needed.
I used to use this sort of filter when I did gas chromatography to filter out impurities in the carrier gas (which was not CO2). I think they would be prevalent in homebrewing only if impurities in the CO2 we use were above sensory thresholds, or maybe if there were convincing data that minute impurities below sensory levels caused health problems (I would be skeptical).
Good memory Bill. There was this thread from 2012: http://www.beeradvocate.com/community/threads/where-can-i-buy-a-co2-tank-locally.43545/#post-553306 While I still have an inline domnick hunter CO² filter on my home system, the big guys stopped installing them on commercial systems about 5 years ago.
I wouldn't ever buy that. If you require a filter for your C02, just buy a new regulator with an inline filter. You'd get an updated regulator and the filter with less to spend. Taprite regulators have inline filters.
