The above figures are based on values from the Compressed Air & Gas Handbook. Calculations assume a conservative cost of $0.25/1000 cu. ft. at compressed air, 100% coefficient of flow, working 8,760 hours/year @ 100 psig.

Your energy costs may vary, however, as you can see any air loss costs you money. There is 3 times more condensate in summer than in winter. On average, over a 12 month period, a timer operated solenoid valve will be discharging compressed air only 50% of the time. Based on the valve orifice size you can calculate energy wasted from the figures above. Our BEKOMAT® electronic level controlled drain traps wasted no compressed air, thus saving time and money.
