In Germany 60,000 compressed air plants use 14,000,000,000 kWh electrical energy per year. 15 to 20 % could be easily saved (Peter Radgen, Fraunhofer Institut, Karlsruhe). Most of theses costs are caused by leakages in the compressed air system. The air “escapes” unused. 1 leak with a diameter of 1 mm = 270 EUR/year.
The LD 300 will be payed off after 4 leakages.
