It is possible to reduce the cost with lower air and energy consumption of compressors. Inlet pressure and compressor electric power cost against operating flow rate (per coupler) [Calculation conditions] Operating pressure at the outlet: 0.5 MPa Compressor efficiency: 0.7 Electric power cost: 15 yen/kWh Annual operating time: 2500 hours Cost reduction effect by using S couplers in a factory It is possible to achieve a large cost reduction when looking at the effect on a factory scale. Note) The relationship between the total compressor capacity, air consumption and quantity of S couplers is shown as a general guideline. [Calculation conditions] 50% of the total air consumed in the factory passes through the S coupler, and 4 S couplers are used at the end of the line. Operating pressure at the outlet: 0.5 MPa Air consumption of one line at end: 1.2 m3/min (ANR) Air consumption time: 20% of annual operating time of 2500 hours Compressor efficiency: 0.7 Electric power cost: 15 yen/kWh Compressor capacity: 8 m3/kWh Energy saving and cost reduction 186
