Industrial Filtration, Separation & Dust Collection worked example

ROI with filtration project investment of 212,500 $: a worked example in industrial filtration, separation & dust collection

What does the result look like when filtration project investment reaches 212,500 $? The full calculation is worked below with real intermediate numbers. Use it when comparing filter upgrades, dust collector retrofits, separator replacements, fan energy projects, or maintenance reduction investments.

The inputs for this scenario

  • Filtration project investment: 212,500 $ (raised for this scenario; the documented default is 85,000)
  • Annual filtration savings: 42,000 $ / yr (unchanged)
  • Annual support cost: 9,000 $ / yr (unchanged)

Working through the calculation

  • Applying the documented formula (Net annual filtration savings = annual filtration savings - annual support cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 6.44 yr for payback period, the number this scenario is built around.
  • At this operating point the engine returns 33,000 $ / yr for net annual filtration savings.
  • At this operating point the engine returns 212,500 $ for filtration project investment.
  • At this operating point the engine returns -47,500 $ for five year net.

How this compares with the baseline

  • Against the tool's baseline example, where filtration project investment sits at 85,000 $ and the headline result is 2.58 yr, this scenario comes in 150% above the baseline at 6.44 yr.
  • A figure at this level is achievable when filtration project investment is genuinely sustained, not just peaked for a shift. Simple payback ignores the time value of money, salvage value, and savings that ramp over time; for long-lived projects pair it with an NPV or IRR analysis.
