Congratulations on receiving the DivAir safe and sound! We're waiting for a dive report.
When you take the cover and diaphragm off to look at the insides, be very careful of the diaphragm. The retaining band can cut the silicone very easily. I put the band on the diaphragm first, then slip it over the rim. I ruined one new diaphragm by putting the diaphragm on first, then trying to get the band over it. The sharp-ish edge of the band cut it like butter.

Hello Phil,
This time the USPS box was in perfect state 😃.
Thanks for the advise. I already remove the cover. But I don't go further, I just look, the diaphragm is very soft and thin, ( I immediately thought, " Fred if you remove the diaphragm, be very careful with it and with the band🥵). I can't use my single tank spiro due to the plate for shoulder strap, but I think the twin tank is ok, and normally it must be possible to hook a second reg in back up.
Cheer's
Fred

Fred, I'm thinking you may want to use some electrical tape: en.wikipedia.org/wiki/Electrical_tapeon the inside of the retaining-band, but with 1-2mm sticking out/protruding on either side/edge: this will give you a soft-buffer This should lessen the need for overly colorful language Good luck and congratulations Jaybird

I'll pull mine apart soon and see if a something like the SCUBA exhaust diaphragm retainer is in order (soft printed buffer between the diaphragm and the retaining clamp).

I don't think anything is necessary but care. If you slip it on band and all, it'll go on fine, w/o worry.

Cheer's Fred There are plastic tubes over the long cover screws to keep the diaphragm from being abraded by the threads. I don't remember if your Divair has new cover screws, but in either case, either new or original, I put new tubing on each one. The originally clear and supple oem tubing is usually hard and black after 70 years. This is the same tubing that I use to restore capillary depth gauges. Don't lose the acorn nuts! They are hideously expensive to replace.

I wonder how many members have DivAirs?
I know JB, James, SwimJim, Fred, Neil, Graeme (?), and I all have at least one. I'm sure there are others.
Anyone else I forgot?

5.30 am wake up, I go down to the cellar, and I try to hook the DivAir on my twin, 🤬 his reserve mechanism is on the way when I try on the center valve ( there is my the right shoulder assembly on the tank)🤬.Finally I hook on the second valve (right side), tanks are 500psi, and... ,... it leaks slowly. I must open and look inside...to be continue😃.
But I must go dive first, I must find a reg.

The HP seat is a used one that I had which replaced an incorrect Scuba seat that it came with. The seat has not been pressurized more than a few times.
Hook up to a full 2250 tank and cycle it a few times before you take it apart. If it still leaks, I'll bet it just needs the lever dropped a fraction.

Spirou, Thank you for the patent number. I usually enjoy going through patents, but this one is most unusual. The first claim is almost undecipherable. Here it is, in one sentence (JB, ‘don’t think you’ll want to even look at this sentence); Again, the above is one sentence. It is 302 words long! It uses “movable means” to describe, I think, the diaphragm and levers. Amazing… That sentence was outdone by claim #10, with one sentence consisting of 355 words: patents.google.com/patent/US2787280A/en?oq=Arpin+US2787280Again, one sentence. Maybe that’s why Healthways bought the DivAir, but then developed its own set of regulators, called the Healthways Scuba. IMG_2916 by John Ratliff, on Flickr John

Thanks a lot , this I will try, tomorrow I must inflate my twin tank.
