Two centrifugal oil-free Turbo Air COOPER compressors have been mounted in the power engineering workshop. These compressors have higher working characteristics than any other oil-free compressor: output up to 160 m3/min, output pressure - 10,5 bar, with control system that allows to ease the use and maintain high efficiency. Air working pressure of forging hammers and die forging hammers was increased due to new compressors from 7 to 10,5 bar that resulted in higher impact energy by forging and die forging as well as increased labor productivity by 25 percent.
