Hi,
It took me quite a long time to put together all the information on inert gas/exit bag method that i ended up needing. I'm writing this up to hopefully simplify the process for anyone else who runs into the obstacles I run into. The one thing i will highlight here is I did not buy the max dog regulator, but the WT farley oxygen regulator that EI/Max Dog uses, and a simple converter to adapt it to the nitrogen tank.
Materials:
1. At least 20 cubic feet/560 litres cylinder of INDUSTRIAL (like what's used in welding) nitrogen gas. Purity of 95% or higher. Before you install the adapter/regulator, release the valve once for a moment to blast out any dirt or debris.
2. WT farley oxygen regulator - search for "Oxygen Standard Body Click Regulator CGA 540". You need a flow rate of 15LPM for nitrogen (and supposedly slightly more for argon, double check on SS) and you want the "barb outlet". When you are using it, make sure the black dial reads "15" for 15lpm.
3. Some kind of adaptor to connect the the CGA580 valve on the nitrogen tank to the CGA540 end of the regulator. Search for "Western Enterprises#415, PKGD: Adaptor CGA-580-540"
4. Oxygen tubing. Standard oxygen tubing + oxygen regulator will eliminate the need to check diameters, etc.
5. Exit bag materials:
i. Oven bags (like for a turkey)
ii. elastic cord
iii. cordlock
iv. micropore tape
6. Wrenches. I got an adjustable wrench, a 1" one, and a 1-1/8" one. These are the same measurements that someone else (i think Fister) gave, which i've cited at the bottom of this post. You need the wrenches to make sure everything is connected securely. Finger/hand tight is not good enough.
How to make an exit bag (Doing it with Betty):
I'm not going to post instructions on how to actually use the exit bag, since other people have done a much better job. Please see the linked threads below for more info. I will just reiterate a couple key things:
1.you need to scrunch all of the air out of the exit bag before you begin filling it up with nitrogen.
2. release the valve on the cylinder ALL THE WAY to prevent leakage from the shaft.
Here are the threads i studied to pull all this together:
TiredHorse's very in depth thread. Read the first two to four pages carefully, and then read FightingSioux's comments at the very end of the thread:
FightingSioux's recent summary. Please read through carefuly, it has much of the same information but i've been more specific about materials in this post:
Max dog regulator is the same as WT farley oxygen regulator: https://sanctioned-suicide.net/threads/addendum-on-nitrogen.3099/post-139877
Fister's thread showing a Medline oxygen regulator, the CGA adapter, and the nitrogen tank all connected:
special thanks to Pane as well, for his very informative posts scattered throughout the threads above.
