1st Stage Repair Recommendation

scubadiver1961 · 20th October 2007, 16:23

I have two Dolphin's with the older style first stages and would like to have them serviced. Does anyone have any recommendations where to send them here in the US? I want a quality job. Thanks

Dale,

Do you know when Drager switched from the piston to diaphragm style first stages? What are the advantages of the newer style?

Thanks,

David

The black cover over it is only a cover to keep hands out of the IP adj screw. It is also not a standard piston used in most regs. In function it resembles a typical diaphragm set up (The piston pushes a pin, which open and closes the seat.
