| The URAL-1 is an back worn rebreather. The webbings are maiden from brown imitation leather. The case is a shell construction, maiden of aluminium. | ||||
 |
||||
| The respiration tubes are connected to the openings at the upper corners, direct to the scrubber. | ||||
 |
||||
| Here's is the SCBA open. | ||||
 |
||||
| The mask is a modification of GP-5, a regular gasmask. The valves are maiden of rubber and a plastic frame. They have a big diameter for a comfortable breathing. The valves are compatible to the KIP-8. | ||||
 |
||||
| Not only a spit trap. The black rubber button together with the small valve is for empty the spit trap in use. Sure, 120 minutes is a long time. The rubber plug is for keep the loop closed in storage. | ||||
 |
||||
| The openings, when the SCBA is in use, are on the backside. Should be a way to protect the SCBA again fire heat. | ||||
 |
||||
| The ID-label with the serial number. I guess 1966 is the building date. | ||||
 |
||||
| The scrubber has volume of round 2000 ml. The exhale of the user goes through the scrubber, into the lung | ||||
 |
||||
| The counterlung is maiden in brown rubber and has a volume of 6 liters. The counterlung has only 2 openings. One to the scrubber and one to the regulator. | ||||
 |
||||
| The aluminium plate on upside is part of the over pressure mechanism. The plate is fixate by a rubber belt. The diameter of the belt is a little bit smaller then the diameter of the counterlung | ||||
 |
||||
| So when the counterlung is nearly full inflated, the aluminum plate press on the valve on let the pressure out. The mechanism open at 5 cmH²O. | ||||
 |
||||
| At the downside, the counterlung has a opening. I guess, it is for cleaning the lung. | ||||
 |
||||
| Here the oxygen part. The parts are in a really good quality. | ||||
 |
||||
| The oxygen tank is difficult to estimate. It is a steel tank in a special size. It must be a volume near 2 liters. The valve is chromed, like medical valves. The tank fits for the regular russian oxygen thread. | ||||
 |
||||
| The regulator is also chromed. Basically, the regulator has a constant flow of 1 liter per minute. The egg-beater is the auto-add valve. When the lung collapse, the egg-beater pressed together and the lever mechanism open the oxygen flush | ||||
 |
||||
| The small lever on the right side is the reserve lever, when the oxygen is near to finish. | ||||
 |
||||
| The lever at the right downside is the manual oxygen flush. | ||||
|
|
||||
| The oxygen gauge. It has a pressure range from 0 to 300 bar. On the glass, not easy to see, is an older calibration stamp. | ||||
