Filter pressure-drop savings estimate calculator

The example treats 4 psi of avoidable loss as about 2% extra energy.

Units

S_{\text{filter}} = C_{\text{energy}} \times 0.005 \times \Delta p

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Given

S_{\text{filter}} = 38{,}000 \times 0.005 \times 6 = 1{,}140

Symbol	Meaning	Unit
$S_{\text{filter}}$	annual energy-cost saving	$/yr
$C_{\text{energy}}$	baseline annual energy cost	$/yr
$\Delta p$	pressure differential removed	psi

Results are estimates for study and screening. Check the inputs, units and assumptions before you use them for design, billing or contract decisions.
