The history of Polish diving apparatus part 3 The next regulator was MORS ... MORS (walrus) Production: Poland Manufacturer: Precision Engineering Manufacturer in Gdańsk Time of production: 1960 - 1969, more than 2000 was made. Constructor: J. Hiszpanski's team of engineers Construction: double hose regulator without one - way valves, combined stages, the 1st counter-rotating stage (reduction to 4-6 atm) the 2nd co-rotating without support (membrane) Together with the reducer, a new type of valve with a reserve device was also designed. Set P-21/P-31: cylinder 2x8L/3x8L, 150 atm, air reserve 40-55 atm (320-440/400-520L) weight 23/30 kg. Heavy diving apparatus mounted with valves upwards, reserve device (pull rod) on the body of the left side cylinder. Drager watertight pressure gauge connected to the valve, attached to the front of the left shoulder strap. Due to the large weight and air supply it was intended mainly for professional divers for underwater work... For under water exploration ... Navy divers with MORS apparatus, dry suit FOKA , full face mask with communication system attached UW recon - diversion team with P21 set during exercises But also for "non professional" divers Typical diving suit "model" for beginners ... which one on the picture is an instructor Used for construction "ambient pressure under water camera case" To be continued... Regards Pawel

I agree, they look like someone's idea of a nightmare: Are there even humans under all of that-- YIKES!

Those FOKA drysuits are not for the claustrophobic..... "Foka" is Polish for "seal" (the marine mammal). The name may have been chosen in deference to Jacques-Yves Cousteau's "Phoque" (French for "seal") constant-volume drysuit: DRW

The PW-2 FOKA & PW-3 KROGULEC dry suit The Grudziądz Rubber Industry Plant "Stomil" produced the PW-2 "Foka" dry suit. It was a two-piece and composed of a flexible helmet (closed with glass) and a space suit...at least two people needed the clothes. It usually leaked a bit so it was "dry" in name only The successor of the "Foka" was the PW-3 "Krogulec" dry suit, production began in the late 1970s. Made of waterproof rubberized fabric, it was a one-piece suit. Helmet closed with glass. Dressing independently is possible thanks to the use of a gas-tight zipper (in an additional part of the suit). Used primarily by the military and professional divers a camel wool undersuit was worn under the suit. FOKA on the left & KROGULEC on the right They were used till early 90' in Navy Training Center There is a link to YT with suit PW2 FOKA using...in the beginning of the film (from 0.40 sec) you can see MORS regulator, next one during the diving is it's successor KAIMAN R7 regulator with P-22 tank set www.youtube.com/watch?v=Tfh_lTUlIv0 Regards Pawel

You are more technically experienced I think ... the mechanizm is "similar" to Drager PA 60-2 regulator , isn't it? What is your opinion about that Rainer Pawel

DAAAAAAAAAAANG! Those things are horrifying: they must have been almost as bad to wear. Huh, I wonder what the BDSM/fetish people think of those? Jaybird

Hello Pavel
Yes , the (Mors/Pa60) mechanizm looks similar. I have no Pa60 to proof . I guess there was a cooperation between ZMP and Dräger .
Greetings Rainer

The history of Polish diving apparatus part 4 The first single hose reg ELF... ELF Production: Poland Manufacturer: Precision Engineering Manufacturer in Gdańsk Time of production: 1966 - 1970 Constructor: J. Hiszpański's engineering team Construction: two-stage automat with separated stages; the 1st counter-rotating unloaded stage (diaphragm, reduction to 4-6 atm) the 2nd co-rotating stage without support (diaphragm). The construction of the second stage was borrowed from the "Aquamatic" of the French company La Spirotechnique.Set P-11: 1x8L 150 atm cylinder, weight 12.5 kg. A lightweight apparatus with a medium air supply, designed for rescue purposes (predecessor SP-1 version for firefighters, miners), training, sports and short-term underwater work / research. The cylinder is mounted on a dedicated back brace with the valve facing downwards and a separate reserve valve knob (air reserve 35-45 atm, 280-360L). A waterproof Drager manometer connected to the cylinder valve was attached to the front of the shoulder strap. Some parts of the previous SP-1 and Mors reductors were used in ELF the apparatus. Experimental "small set" P-12 with chest mounted 2L air tank was tested but never produced...unfortunately To be continued... Regards Pawel
