O2 conversion on Sierra Booster

[Ty Hamby]

To kick off I think it best to first define the outline design performance parameters and requirements.

1. Define your requirement of scavenging.

Down to a pressure that makes sense. I dont want to spend thousands more to get down 25 more psi. If scavenging cylinders down to 300psi is doable and only throwing away the last 300psi of 21/35 or 100% deco gas makes financial sense then this. Clearly I don't know what I need to know. Help me learn. That is why I am here.

2. Stainless tubing I would avoid at all cost and suggest an Alpha Brass or bronze material such as Tungum.

Ok, Will look into other tubing options.

3. You will need to modify the heads and the spring on at least the discharge side from the original piano wire steel to at least an inert to oxygen

4. Filters? what filters if inline filters for particulate contaminant then again you should use brass body

Ok. I assume modifying the heads is something doable.
OK. Will look into brass.

I am starting to think buying a Chinese booster pump that is easily thrown away when defective, might prove to make more sense.

Ok, what are the turnkey options?

And you’re using parts from Masterline to do the conversion?

When parts are needed, yes I get them from Masterline.
