Inflating Jacket from Dolphin Reg

**Dave1w** · 12th October 2006, 05:58

As most LP hoses are rated to around 27 bar, apart from the redundancy issue, can anyone see a problem a with running a LP feed to a wing from the Dolphin reg (about 16 bar I think)?

Will I need think about having the best quality inflator to handle the extra pressure, or should it be OK?

Another thought, has anyone run the Ray dosage from the dolphin 1st stage?

I know the dolphin one doesn't like to work with the Ray 1st stage, but I wonder if it is OK the other way around.

Cheers
Dave

Hi Dave.

There is no problem in attaching a normal inflator hose to the Dolphin 1st stage. I have been doing this myself.

Although I have never tried to, I don't think the Ray dosage will work on the Dolphin first stage as it is designed to use with an IP of ~11 Bars (as far as I remember) and hence the dosage will freeflow and/or the flow rates would be way too high.

Because of the design of a BC inflator I dont think there is a problem on Dolphin reg.first stage: The highest the pressure is, the more the valve is firmly closed ( its the contrary than on a second stage reg )

You cant use a Ray dosage ( in fact 2nd stage Ray ) on a first stage dolphin because it is both a ADV and a dosage device,youll get instant freeflow or you have to decrease the IP of the first stage so low that you cant go at depth and anyway inthis case the dosage orifice of the ray is not correctly rated

You might have a problem if you have the old style drager 1st stage, doesnt it use a different thread? I dont think a std LP (3/8?) hose will fit.

I believe the new style Drager 1st stage would be fine.

Yes. The new Drager 1st stages are fine.
You are right about the old style 1st stages.

can get adapters at Tauchen - Cave, Nitrox, Rebreather Ausbildung, Tec Ausrüstung, Reisen to fit a standard LP hose

I suppose the bypass problem could be solved by swapping out the spring form the dolphin. To be honest I wasn't thinking too straight, with regard to the effect on hte bypass, and really, I don't think it is worth the hassle.

Basically, I am looking for the simplest, most compact way to run a ray bypass.
I think I may go with a standard nitrox reg 1st stage, then will be able to go with bailout and run a wing.

Cheers

So what was the problem with the original Ray first stage

it IS a standard nitrox first stage

By the time I have put in my din to drager adaptor, and then the Ray 1st stage, when it is on a standard tank back mounted, it is too long. That's all. It digs into the wing/neck.
The dolphin is smaller, and an apeks would be even smaller.

If its the length of the Ray first stage with a DIN adaptor thats the problem, Tecme do a Conversion for the Dolphin first stage that removes the Drager fitting completely and replaces it with DIN instead. Which means the 1st stage is as compact as any DIN Reg. I use one and its great.

I suggest it might be worth asking Martin (Tecme.de), if it can fit the Ray. If your lucky, he might even reply to this post
