Explain about the importance of optimal Pressure settings of a compressed air network Answer : The power consumed by a compressor depends on its operating pressure and rated capacity. They should not be operated above their optimum operating pressure as this not only wastes energy, but also leads ... switches must be adjusted such that the compressor cut-in and cuts-off at optimum levels. ...
