Drysuit inflation with a rebreather

Graham · 18th April 2006, 13:19

I was thinking of ditching my 6cuft drysuit inflation cylinder and running the feed from the bailout, as it would get rid of one extra piece of gear for now.

This thread is good, but what are the pros and cons of each method?

A big con for me in running it off the bailout is the scenario of handing off the bottle for whatever reason and losing the drysuit inflation. Although the counter argument would be that the dive is over at that point and on ascent, inflation is not needed. But what if it was an overhead dive and we still had to exit?

Thanks for all the suggestions.

I'm going to just run it off the dil for now.

Also decided to go with the Classic instead of the SK.

Click on my avatar to look at my profile pic. I carry a 13cuft inflation cylinder secured to the CK frame I got from John. Works like a charm and is completely out of the way.

Looks nice, if I ad one in the future I'll probably just do a 6cf mounted to my plate, though.

If I ad a frame to mine I'll sink like an anchor!

I bought 2 6 cubic foot cylinders and have them both filled with air. I mount them on my plate and have only once run out of inflation gas, and I think that was on the second dive on the bottle. If you run out of inflation gas, you can switch over to your bailout tank or, if in an already stressful situation, just ignore it, as you don't need to add gas while ascending... I have the second bottle so I can just switch over between dives. They are very easy to transport and store - I keep my backup bottle in my save-a-dive toolkit.

Just wanted to report that even when using a 6 cu ft suit inflation bottle mounted on the side of the Transpac, I can still sidemount sling bailout bottles on that same side. I have used a 19 all the way up to an 80 and I don't even notice the suit inflation bottle --They both fit with no problems on the same side.

Does anyone sell a complete solution? i.e. Bottle, firststage and hose? I have been looking and can only find a bottle...

Cheers

O.M.S. sells the complete Dry Suit inflation system.
Dive Rite said they have one according to the web site.

But as we all know both companys love there toys so be perpared to spend the money for them..

Have a look at TDL. I have just added a 6cuft filled with air to my Evo after I froze my ar5e off when I used trimix from my bailout for my suit. I have found the little 6cuft cylinder fits down the side of the Evo next to the wing and is completely out of the way. I have a small piece of webbing between two hose clamps and this is passed through the strap for the O2 onboard and tightened up.

Joel from TDL is on this forum as well and will give you any information you need. I have found the guys from TDL to be quite helpful.

Argon-06-Fill

Argon Inflation System with 6 cuft 3000 PSI Cylinder and Fill Station Filling Adapter

● Integrated Regulator-Valve
● Aluminum Cylinder

● 22" Hose with Easy Grip "Hose-Hat"

● Over pressure Relief Valve (OPV)

● Fill Adapter (fill station style)

● Argon Label (not installed)

TDL Dry Suit Inflation System is a self-contained integrated valve and first stage assembly Measuring only 2 3/8 inches tall this is the most compact valve/regulator system in existence. The regulator is a balanced piston first stage with an intermediate pressure set at the factory at 120 psi. Each regulator has 2 LP hose ports and one HP hose port for a gauge, a safety assembly (burst disk) and a special one way fill valve is built into the regulator to allow for easy filling with the fill adapter.

The TDL Dry Suit Inflation System is an active regulator valve system that it is always "on". No knobs to turn, no valves to check before diving. As long as the suit hose is connected and the cylinder is full, it works.

I have been using this specific system for at least 3 years with no problems. Plenty of gas for multiple dives, its small and lightweight. I mount it on the left side of my backplate using some left-over 2" webbing to hold the body of the bottle and a 1/4" bungie loop through a hold on the bottom corner of the plate where I slide the regulator through (bottle is mounted upside down). It's secure, out of the way and I don't even notice it. I only ran out of gas once - my own fault, I forgot to fill it!

An ex-work colleague conducted a dive using nitrox, used it as his drysuit inflation gas and due to the gnawing cold had a couple of charcoal handwarmers in his undersuit pockets...

The handwarmers were somewhat more efficient in the high O2 environment and badly scorched him and his undersuit!
