In 1871 the known Russian inventor A. Lodigin has offered independent diving equipment. Little bit later A. Hotinski has designed the underwater oxygen respiratory device. However all these important inventions in the field of diving engineering, as well as set of other Russian inventions in the past, because of indifference of the imperial officials have not found application in diving practice.

Long time the oxygen respiratory devices were applied mainly in a mountain industry at collapses (landslides) in mines (shafts). In the first world (global) war they under the name oxygen isolated of gas masks (KIP) were used in chemical divisions of many armies of the world.

The wide development and use of independent oxygen devices for underwater works is caused by necessity of application them at failures of submarines. Fears of the people from the sunk submarines needed special individual devices. In the twentieth years the devices of the foreign marks “Momsen”, “Davis” and hood “Belloni” have appeared, last worked by a principle of a diving bell. Individual - saving devices of these marks in one time ‘ were on supply of submarines.

In 1931 — 1932 the Soviet engineers together with the doctors - physiologist have designed perfect underwater devices of the marks “E” (Epron) and VAP.

"E" (Epron)

The next two - three years the diving devices were let out for NAVAL Fleet under the marks E-1, E-2, E-3, E-4 without bypass and E-5 with bypass. Further in a niche to the country new samples of devices were created: VAP-1, VAP-2, IPA-1 without oxygen-giving mechanisms and IPA-2 with the oxygen-giving mechanism of lever system.











In 1936 the advanced design of the diving device IPA-3 was developed. The occurrence of devices working on oxilite Substance, absorbing carbonic gas and allocating oxygen concerns to the same period, However and these devices have not received distribution in diving practice.

The efforts of our designers in the same time (1939) created one of the best samples of oxygen respiratory diving devices — ISA-M. This device had the very reliable ISA-Moxygen mechanism.















Now isolated the oxygen respiratory devices (IDA) are widely applied to performance of various underwater works. The first time at use of these devices was many cases of various diseases, the oxygen famine is especial. The intervention of the doctors -physiologist has helped to prevent cases of diseases. Huge work in this area have done military - medical academy of a name Kirova and organized in Leningrad the laboratory on preparation of the naval easy divers is scientific - test.

The significant work on improvement of the isolated oxygen respiratory devices was executed also by (with) the army designers. So on a strictly scientific basis in our country there was a new branch of diving business — Easily diving.

Just the military experts possess creation legendary not only in Russia but also abroad series of devices under the name IDA. From the very beginning development of devices of this series went on two directions. It is devices intended for crews of submarines and devices intended for realization of underwater, technical works. Last has defined (determined) destiny of many devices as espionage.

And so under the order:

In 1955 from a marine sea fleet the order for manufacturing of new oxygen devices suitable as for use was received as saving means on submarines, and for realization of various diving works on small depths.

In that to year the experimental model under the mark IDA-55 has appeared, but on what that to the reasons it has not received the further development and beat is overlooked (forgotten). And only in 1957 there is a new model of the oxygen device IDA-57 which with the large success passes tests and admits suitable for use army and on fleet. Till 1959 model “57” was used as the universal device which applied as during emergencies (fires poisoned atmosphere, output (exit) of crews from the sunk submarines), and at realization of various works under water on depths up to 20 meters.

The IDA-57 is a simple and robust 02 rebreather designed in 1955. It is a very close technical sister to the early Dräger rebreathers, and was used in service (USA. red.) through the early 1970's. They are fairly rare, having been discarded as replacement equipment became available. I was fortunate enough to obtain a new (un-dived) example for my collection, and present it without further fanfare for inspection. I'll dive it this spring, as soon as the weather warms up, and have high expectations for it. It will be interesting to compare it to a Dräger LAR-III, which is the oldest Dräger that I have available. It'd be more comparable, I think, to a Dräger Lieutenant Lund, which is the most widely known of the first-generation 02 rebreathers. This rig is certainly represents pre war 02 rebreather design, its post war date notwithstanding.

The device is developed in 1960. It is intended for carrying out of underwater search works. The device is the closed cycle of breath. The exhaled gas mix is cleared of carbonic gas by absorber HPI and enriched with oxygen from cylinders with constant inlet velocity 0,5 - 1 l/minutes. A regenerative cartridge of the cylindrical form with two environments. The similar design of a patron in other devices is not applied. The maximal depth of immersing - 20 meters. The device can be made in antimagnetic variant.
