Industrial Filtration, Separation & Dust Collection worked example

ROI with filtration project investment of 42,500 $: a worked example in industrial filtration, separation & dust collection

Suppose filtration project investment falls to 42,500 $. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate payback for filtration or dust collection improvements from project cost, annual savings, and ongoing support cost.

The inputs for this scenario

  • Filtration project investment: 42,500 $ (the input this scenario stresses; the baseline uses 85,000)
  • Annual filtration savings: 42,000 $ / yr (held at the documented default)
  • Annual support cost: 9,000 $ / yr (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Net annual filtration savings = annual filtration savings - annual support cost.
  • Payback period works out to 1.29 yr at these inputs, and this is the headline figure for the scenario.
  • Net annual filtration savings works out to 33,000 $ / yr at these inputs.
  • Filtration project investment works out to 42,500 $ at these inputs.
  • Five year net works out to 122,500 $ at these inputs.

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 50% below the baseline at 1.29 yr.
  • It computes the payback period in years by dividing the project investment by the net annual savings (annual savings minus annual support cost). When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
