How does raising or lowering pressure affect my energy costs?
A rule of thumb for nominal 100 psig systems is for every 2 psi the resultant energy change is 1%. So if you lower your system pressure by 10 psi the change in energy at the compressor should be 5%. Try it and use a simple clamp-on ammeter to measure the results. Let us know the data and your energy rate and we will help you determine the cost differential. Additionally, operating at a lower pressure reduces leakage rates and air usage in unregulated devices which may provide an additional energy savings benefit.
