Method Exit bag and inert gas megathread

[Nocturna666]

US SCBA:
Drager 2216 psi PAS Lite
Drager FPS 7000(R56200)
CGA-580 to CGA-346 adapter
~2000$

US hood setup:
Drager rescue hood~250$
Drager CEJN 344 coupler~140$
ACU-200 reg~100$
Middle adapter(CGA-032 to 1/4 NPT)~15$

Both will kill you,the choice is yours

Hey, I don't know if you are still active on this forum since it seems that you posted sometime ago but if you do happen to see this, could you let me know whenever you get the chance if the cga 580 to 346 adapter actually fits with the pressure reducer that comes with pas lite? There was another member on here that made a good point which I'll quote but to my knowledge did not buy the pas lite due to doubts the connection would work. Hoping to get some clarity since I'm using Scba and am based in US.


"the photo shows a male connection that wouldnt connect to the adapter.
This scba system with this male type of connection is used for connecting to an airline. The system has an integrated Automatic Switch Over Valve (ASV) and a male airline connection kit. This allows the wearer to breathe from an external airline and automatically switches to the cylinder (back-up) air if the external supply fails.
These are the 333358743 (2216 psi) & 3358744 (4500 psi). The adapter will not connect with these systems"


The photo showing the example of this drager scba setup was posted by yet another member of this forum. his name I honestly can't remember, but it claims to be the first stage pressure reducer from pas lite though upon inspection it looks different in appearance.

Sorry, I should have clarified that the previous system with the male connection is another model of PAS lite. 333358743 It for use with a airline.

The photo of the system that connects to the brass adapter is another PAS lite model. 4046190 (2216 psi)
As in the photo, the first stage pressure reducer has a 'black' wheel....female connection. The brass adapter (male) fits into that. They are CGA-346 types of connections.
The part of the brass adapter that fits into the cylinder is a CGA-580 connection.
There is another PAS lite model that is for higher pressure tanks (4500 psi) 4046191....they have a 'blue' wheel and use a CGA-347 connection, and there is a way to make them work with a cga-580 adapter as well.

Ok. thank you for shedding some light on the differences between the two, it helps a lot.

The photo of the reducer with the male connection....I think that is a G5/8" type of threaded connection. Its a UK/EU type of connection.
There are adapters....G5/8 to CGA-580
(cga-580 is the usa inert gas thread connection to a cylinder....its the male rounded pointy end of that brass adapter).
The issue is trying to find one that is G5/8 female to a cga-580 male.
I dont think this kind is made...the only ones Ive seen are male to male.
(edit) There are G5/8 female to G5/8 female adapters.....so this system could potentially work.

Sorry for the confusion......

PAS lite 333358743 and 4046190 are basically the same model.
They are both for 2216 psi cylinders.
The 333358743 just has an extra hose assembly that allows one to connect to a hose supply. The rest of the system should be the same.
The manufacturer just gives them different models based on what they are grouped with.

They both have the same connections to the cylinder (cga-346 which is for 2216 psi), that is if they are the USA models.

The photo of the scba pressure reducer that shows a male connection, it is a UK/EU model. I believe it is DIN 477 G5/8 type of connection.
There are adapters to get it to connect to that brass adapter cga-580.

Hi, I've built my helium setup. What are your thoughts on this? Let me know if you have any advice. Thank you.

Finalized my helium setup. what are your thoughts on this?

Here's my helium setup. You might be wondering wtf is going on in this picture so to put it short, I want to CTB by inhaling helium while asleep without fear or discomfort. So it basically consists of air pump motors and a solenoid valve, controlled by timer plugs to flow air and helium with a...

Well thought out from an engineering perspective.
The air pump motors (3 qty) are for pushing normal air to the mask? How did you determine that 3 were needed? 1 or 2 would not get the needed air flow to the mask?
So the fans turn off based on a timer switch....then another timer switch opens a valve to allow the inert gas to flow.

What kind of mask is that? Just a regular respirator, i.e. the kind used for spray painting or other similar uses?
Being asleep while all this happening may introduce issues that might be a failure point.....Some have suggested restraints of arms and legs.

I am curious, can you list the parts, models etc...

I replied in the other thread.

I wondered if anyone knows if this can just be attached to inert gas rather than oxygen? With some kind of adaptor I'm guessing.

The harness, regulator and pressure reducer arrived. Now the problem is removing the harness from the pressure reducer. I looked up instruction articles and videos but nothing is shown on what tools for removal. The adapter DOES fit though so that's a huge plus.

For that Scott scba system, what is the silver box (photo on the left)? Is that the pressure reducer?

So it does appear that with the brass adapter, that the scott scba does have a cga-346 connection (assuming its 2216 psi scba model).
Seems all the scba manufacturers use the same connection type. Confirms my findings as well, I have a Scott air tank that fits my drager pressure reducer.

It appears this system is meant for use with an air compressor with a hose / quick-connect type of coupler. But there are adapters that could be made to attach from a cylinder tank that has a hose attached to it with a coupler. This is from Sweden (EU) so I am unaware of the tank cylinder types of connection attachments. One would need to research what that would be and then find an adapter that would connect to the cylinder and to a hose with a quick connect type of coupler.
