Air revitalization plant on U-2540 (Wilhelm Bauer) Air cleaning system The CO2 enrichment in submerged operations can be measured with the Dräger device onboard. The air cleaning system starts when the CO2 content exceeds 1.5 %. The air cleaner contains calcareous granules which bind the carbon dioxide in the air. One air filter filling is sufficient for about 4 to 5 hours of air purifying. To refill the air cleaner (2 canisters) the filling of 4 potash canisters is necessary. 450 potasch canisters are onboard as replacement. The calculation is based on the following data: The air volume inside the hull is 900 m³. The crew consists of 60 men. The carbon dioxide output per man and hour amounts to 10 litres during sleep, 20 liters during light, mostly seated activities, 30 litres during heavier activities. Further calculations are based on the average, i.e. 20 litres per hour and man for ordinary submerged operations. Basis of the oxygen requirement is the CO2 requirement + 10 %.

Diesel engine room Of the machine rooms of the boat, only the back portion of the electric engine room is in its original condition. The Diesel engine room used to house two 6 cylinder MAN diesels, which through the use of a Vulkan clutch and gear box each ran one of the both propellers. With the conversion of the boat, this diesel-electric machine was put in: 2 12 cylinder MB 820 diesel engines with an output of 600 hp each at 1400 rpm Make Daimler Benz and 2 BBC generators with an output of 405 kW Make BrownBoverie Cie. This means that at the Federal Navy, the boat ran only using the electic engines. While diving at shallow depths, the diesel engine could be supplied with air using the so-called Snorkel, which, like the head of the periscope, reached above water.
