Drysuit inflation

Sune Jorgensen · 9th April 2008, 05:16

How do I add drysuit inflation to the onboard dil without using the first stage bottom LP plugs?

Stephane · 9th April 2008, 05:56

Hi,

Replace the long DS hose with a short 2nd stage one and put at the end an Omniswivel Y-Block like this:

Then two short Direct-System hoses.
I will post photos later this morning.

Thanks

So I guess I would need these two:

Yes, correct.

The rEvo comes with additional mounting brackets.. You are much better off using an independent drysuit infaltion ssystem.. get a 1 or 1.5l cylinder.. it adds hardly any weight and keeps the potential failure points down..

if your diving deep stay in the 1.5-2l range.. in that case you definately don;t want onboard!

There is another solution Joe: the side bracket is used to mount the external diluent bottle for deep trimix dives.

In this case, the inboard tank is only filled with air and is used for shallow dives as diluent, dry-suit and BC inflation.
For the moment I'm using a S006 tank but that's just enough for one dive.

You must use alot of gas in your drsuit.. even on 80m dives I get at least 2 dives on a s006 with plenty to spare..

The S006 is the external diluent tank.

The drysuit/BC inflation is always from the 3l inboard tank.

Sune have a look in this forum for a thread by Dave S, titled 'Nice Pair'.

I know Joe writes that it reduces failure-points to add a drysuit tank, this is in fact wrong. It adds more gear and hence failurepoints. However it adds redundancy to boyancy-control.

But... when you are diving drysuit, and never use the wing anyway, there is another way: Use onboard O2 for wing, and onboard Dil for Drysuit.
Less gear, same redundancy, and by using a breathing-inflator you get OC-access to your Onboard should you need it during a bailout...

Doing Trimix use offboard Dil.
Building the system right now, just recieved my CEJN-221 couplings.

I guess it is how you were taught to use a drysuit.. I find exactly the opposite.. The wing is used mostly for buoyancy, and gas is only added to the drysuit to eliminate squeeze..

I NEVER use the ds for buoyancy.. too big a gas bubble to move around and too much of a risk should you go head up and the gas burps out your neck seal..

I stand by the opinion that it reduces failure points on the rEvo.. on the stock rEvo, the only way to add gas is using the onboard diluent or oxygen, it you lose it you are screwed.. Save the breathable gas for when its needed.. a stuck DS valve could quickly deplete you diluent.. If you start adding in sources to plumb in other gas sources into the loop then its less of an issue in my mind..
