I won a Divair on eBait recently, and have no idea as to how it works: I have yet to receive it. While trolling I found one for sale as parts:  I took the image from eBait and isolated part of the image. From this image I instantly figured out how to make a second non-return valve. The regulator I won has its original Hope-Page mouth piece, that has a non-return valve too, so my mod will hopefully keep this breathing even better. More later, Jaybird |

Jaybird,
I don't think the DivAir had a second exhaust valve, nor did it need one due to the placement of the exhaust opening. 'Just a thought.

Okay, so the reg is on upside down... and backwards:   But, it's a Divair! Okay, with that last image, I'm sure you're saying, "WHAT DIVAIR?!?!?!?" Jaybird |

Reading Basic Scuba, Fred Roberts mentions that, "Hoses have been added to give a hint of 'wintergreen' flavor when you breathe." HUH!?!?!?! I guess they were thinking ahead for when you meet a really hot mermaid!  Jaybird |

Hi nikeajax Since that film came out in 1957 I would go for the "E" & "F" models. Must try to get out more!!!
PS. The late James Garner used a "Divair" in the film "UP Periscope"

That is a sweet reg Jay. I have no experience with them, but they were around in the beginning, so the design is truly one of a unique vestige.
I'm looking forward to your reports on the restoration and first dive(s).

John, I was unaware that they made anything after the B-model, which is what I'm getting: but that doesn't mean anything  The B is the black fiberglass bodied reg. Do you know something I don't, I hope? Jaybird |

GRRRRR! I didn't mean "B", I meant "C"!  The reason I thought this is because Basic Scuba says there were only three different ones, but now we know there are five... Adair, I took this from your site, thank you (translated from Portuguese): "There are no catalogs, manuals or advertising materials in any mention of classification of the models produced Divair, either LETTERS or NUMBERS. What exists in the literature are the improvements and updates to each model.
The L.G Arpin put the letters "A", "B" and placed "C" before the serial numbers to identify a specific type of design or production. To wit: "A" for the first series of regulators produced, "B" for the second series of regulators and "C" for the third series. But, for some unknown reason, the use of letters, prefixes in the numeric ranking was ceased when the plastic body was introduced.
It is believed that the Technical Service Department of LG Arpin wore terminology MODEL A, B, C, E or F to facilitate the identification of parts of various models of regulators. The Healthways and the Unity Service also used this system." UFF-DA! That was a lot to translate (the whole article), but I think I got through it! Jaybird |

Dang John, yer totally right about it being an "E" in the image: I remember watching the movie and saying to my wife how insanely long the hoses were! They were Healthways "Air-Flo" hoses, and you can make out in the image a Cressi Medusa mask, as denoted by a slightly triangular shape and the hoses are attached to the sides of the mask. I should note that the Air-Flo hoses were nine-inches, but could be stretched to... 63!  The "F" model had regular-normal hoses, closer to what we're used to seeing. Okay, I know, more nerd stuff, but who knew! I found this really dark image were you can see the mask has an underwater telephone attached to it:  Jaybird |

Okay, here it is, it just came this morning:  Special thanks to Sitka Dave: in image is a Healthways-Divair valve with nylon seat! Dave sent me two when my HW valve got buggered up. This unit is serial number 10588. More later, Jaybird |

 Note the nylon tubing on the screws: these are to keep the threads from cutting into the diaphragm. Jaybird |

If there was any question as to how new the technology was when this regulator was made, look at the images again; notice anything odd?
Look at the reserve...
What side is it on...
YUMP: it's on the right hand side... and NOT on the left! I don't think we get to call it a J-valve, do we?
