Max pressure for Dolphin 1st stage regulator?

4ster · 25th July 2007, 00:58

Is the maximum working pressure for the Dolphin 1st stage 200bar/3000psi? That is what is engraved near the HP port. I have been searching in the manual for the spec and can't find it.

I have a couple of cylinders with a working pressure of 3443 that I would like to fill to their full capacity. Until now I have been filling them to 3000psi.

Assuming that I use a DIN valve and DIN to Drager adapter and not a Drager tank valve, can I fill to the higher pressure? (One cylinder has a Drager valve on it and my dive shop blew its burst disk on the first fill!

)

I have used 232bar bottles, filled to about 240bar with no problems, but that is of cource no guarantee that it works for you....

It is normally rated to 200bar yes.
