Filter life and dirt-holding capacity are limited. لذلك, compressed air quality cannot be guaranteed when its life expires. عادة, the replacement cycle of our filter element is 8000 ساعات.
فضلاً عن ذلك, it is not only to ensure air quality but also to consider pressure loss and energy consumption. The additional power of the air compressor must compensate for the pressure loss of the filtration system. نتيجة ل, the power consumption of the compressor increases. مؤخراً, operating costs and expenses will rise. Now take two examples for comparison.
Example:
Electricity fee: 0.07USD/kWh,
For every 100SCFM air consumption, the pressure loss will increase by 1PSIG,
Finally annual increase in electricity bills due to pressure loss: 67 USD.
Case 1:
Filter element purchase cost = $400.00;
Air consumption = 500 SCFM;
Initial pressure loss = 2 PSID;
Pressure loss before filter element replacement= 5 PSID;
Filter element lifetime = 6 months;
So average pressure loss during filter element use: 3.5PSID;
Increased electricity bill: 3.5 X (500/100) x 67 = 1,172$;
Because replacing the filter element is twice a year, the total annual cost is 400X2 + 1,172 = 1,972$
Case 2:
Filter element purchase cost = $400.00;
Air consumption=500 SCFM;
Initial pressure loss = 5 PSID;
Pressure loss before replacing the filter element = 10PSID;
Filter element service life = 1 سنة;
Average pressure loss = 7.5 PSID;
Operating electricity bill increase = 7.5 PSID X (500/100) X 67 = 2,512$;
So total annual expenses = $400 + $2512 = $2,912
ختاماً, in case 2, the filter element was used twice as long as in case 1. لكن, the total cost increased by $940 due to a bigger pressure loss. So much more than the cost of replacing the filter element ($400). هكذا, we must exchange the air compressor water separator filter element in time.
