| Oxygen Booster in Manifold?
Hello!
I am in the process of deciding whether to build my own partial pressure manifold to blend Nitrox and in the future Trimix (Global used in picture as example). What I want to know is whether you can have the booster permanently plumbed into the manifold prior to the whips? All gas would pass through it requiring the entire system to be Oxygen clean. Therefore, the ability to boost is there without having to disconnect the cylinder(s) from the whip.
My thoughts are buying a compressor to fill via a tee 1) a two cylinder bank and 2) the booster. From the cylinder bank would be filters to get my modified Grade "E" air. The remainder of the manifold would have the necessary needle and slow opening valves that lead to the inlet of the booster? What I don't know is whether any of the boosters are designed to allow gas to freely pass through them or do I need to plumb a bypass loop for boosting?
I'm thinking once cleaned I rather not connect and reconnect fittings, risking potential for contamination and only design it in a manner to disassemble for re-cleaning.
With max. depth of 100 fsw and most sites in 40-60 fsw I'll be blending a lot of EANx36 & EANx40 until I get my rebreather. |
