The KG (German: Klein-Gasschutzgerät - small gas protection device) serie was designed before the Second World War by Dräger for the Civil Defence and Fire brigade. It was exported to many countries and used till the end of the 1970s. It is easy to confuse it with other Dräger and Degea Audos MR rebreather series.

KG 1928 Edit

It was the first rebreather in the KG series and one of the first rebreather produced by Dräger which used the "backpack" configuration making it much more compact than the previous hip or waist mounted ones.

Facepiece Edit

It could be used either with a mouthpiece and a nose clip or with various other facepieces. Like the Leder B-Maske being the most common.

Backpack Edit

It is very similar to the later KG 130 however the easiest way to distinguish them is that the KG 1928 lacks of the additional equaliser valve under the mouthpiece. The backpack contains a regenerating cartridge filled with bariumhydroxid, a breathing bag and a oxygen source tank. It is connected via two hose to the mask. It could provide enoug oxigen for an hour.

KG120 Edit

The KG120 rebreather was designed before the Second World War by Dräger mainly for military use but it was used by the Civil Defence and the Fire brigade too. It was license built by many companies during the war but it kept the designation. It was exported to Hungary where the device was used until the 1960s.

Facepiece Edit

The facepiece is an early GM-30 mask but without exhale valve, later is was used with the GM-38 and the ebu made devices were used with OPT masks. In Hungary it was used with the 34M mask as well.

Backpack Edit

The breathing device can be found inside a wooden box with metal case where the apparatus itself is located. The case has two leather carrying straps for attachment to wearer's back and one strap to attach around waist. There's a manufacturer's logo on the case and the name of the apparatus Heeres-Atmer KG120. Inside the case there's an oxygen tank, leather pouch and a carbon dioxide absorber. Corrugated hose with pressure gauge is attached to the case from outside, together there are two hoses - one is for inhaling and the other one for exhaling. These hoses are attached to the mask. The system worked automatically as the user breathing. The wearer could also regulate the oxygen supply manually if it was necessary. The exhaled air flowed to a leather pouch covered in rubber material with capacity of 5 liters through a carbon dioxide absorber. This pouch served as an air storage nad was connected to the regenerating cartridge filled with bariumhydroxid. The air from the pouch was later mixed with oxygen from the tank and was again inhaled by the wearer. The case had also built-in horn which warned the wearer in case he forgot to open the oxygen tank. Pressure of air flowing from the tank automatically turned the horn off. It could provide enoug oxigen for an hour.

External information Edit

"The Russians found a Heeresatmer set in Hitler's bunker when they searched it in May 1945. There is no direct evidence that it was actually for the Führer's personal use, but it is quite possible: "A door led to Hitler's bedroom...here was a bed with a night table...a safe in which he kept secret papers...and oxygen apparatus."  Cabinets in a nearby corridor contained ordinary gas masks and other air-raid equipment."

After the war Chirana, a Czechoslovakian company continued to produce the rebreather as CH146.
