Air consumption

Air consumption By analyzing routines and the use of compressed air, you can find solutions that give a more equal load on the compressed air system. The need of increased air production can thereby be kept low, which reduces operating costs. Increasing general awareness best rectifies unprofitable consumption, which usually depends on leakage, worn equipment, processes that have not been adapted or the incorrect use of compressed air. Dividing the compressed air system into sections, that can be separated using valves, can be a method of reducing consumption during the night and at weekends. In most installations there is some leakage, which is a pure loss that must therefore be minimized. Frequently leakage claims 10-15% of the produced compressed air sometimes even more. Leakage is proportional to the working pressure, which is why one method of reducing leakage is to repair leaking equipment and lower the working pressure, e.g. at night. A lowering of the pressure by only 0.3 bar reduces leakage by 4%. If the leakage in an installation of 100 m3/min is 12% and the pressure is reduced by 0.3 bars, this represents a saving of approx. 3 kWh/hour, which is equivalent to the electricity consumption in a normal electrically heated home. Even the air consumption for machines and equipment increases with an increased working pressure.  
The diagram on your left, shows how consumption can be spread during a week and 24 hours per day. Consumption is low during the night, high during the day shift. It drops during breaks, but is constant during the weekends (leakage or production
