idk too much about co2 scrubbers but id just be worried about impacting the seal of the bag if im adding extra things to it, if the co2 scrubber is quite bulky it could make the bag a bit "uneven" on one side if you know what i mean? so the seal might be tighter on one end than it is the other, its not something that id personally do as the gas and the seal not being airtight serves the purpose of flushing co2 but it could potentially make it more comfortable but i mean from my own failed attempt with helium i didnt find the exit bag that uncomfortable tbhI made another discovery today when testing out a freshly made exit bag. Instead of nitrogen I used a Husky 120V Tire Inflator with a rated output of 27-30 liters per minute. Everything functioned perfectly. The bag was nice a taught without any risks of bursting or flying off. I did not feel really hot right away inside the bag like I did with the nitrogen at 15 LPM. In fact I was quite comfortable and was able to pretend to be an astronaut which was highly amusing. The bag did not deflate nearly as much on inhale which shows me that air probably isn't leaking in. After about two minutes I felt very slightly light headed but medication that can cause that so IDK if being bag boy for a few minutes caused it.
Now this doesn't prove anything it just suggests that 15LPM is not enough to be totally comfortable and that 27LPM wont blow off the bag. (at least I think I'm at 15LPM nitrogen I have no way to accurately measure because welding flowmeters aren't scaled for pure nitrogen).
One more thing. Taller tanks like the 80cuft I have really want to tip over when pushed or if you pull on your hose. I suppose since there isn't any liquefied gas in a welding tank of nitrogen you could operate it on its side so It can't come crashing down, but I'm sure there are lots of other reasons not to do so. Consider ratchet strapping the tank to the bedpost or use a tank cart with chocks on the wheels.
I've been reading through the Exit Bag and Inert Gas Megathread and I discovered what MDB means. It is Mad Dog Brewing which is a defunct gas bottle/accessories dealer from Australia. I GODDAMN HATE NON-STANDARD ABBREVIATIONS!!! You guys have GOT TO STOP using them. Its a huge problem on this forum. It may save you a second or two at the most but it costs hundreds or thousands of man hours to everyone else. Each reader who isn't hip to the bullshit probably wastes at least an hour trying whilst looking for context clues and searching the web.
Finally I just had another idea. What about a CO2 scrubber for inside the bag to help the N2 remove all CO2??? Or is no one willing to play with me anymore?
