Industrial Filtration, Separation & Dust Collection worked example

Downtime Cost at 110% affected production share: a worked example in industrial filtration, separation & dust collection

Push affected production share up to 110% and the picture changes. This example computes every intermediate figure at that operating point. Use it when planning filter changeouts, baghouse outages, separator cleaning, filter press service, or emergency collector repairs.

The inputs for this scenario

  • Filtration downtime hours: 6 hr (unchanged)
  • Cost per downtime hour: 4,200 $ / hr (unchanged)
  • Affected production share: 110 % (raised for this scenario; the documented default is 100)
  • Fixed restart and cleanup cost: 1,800 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable filtration downtime cost = filtration downtime hours × cost per downtime hour × affected production share) to the inputs above produces each figure below.
  • At this operating point the engine returns 29,520 $ for total filtration downtime cost, the number this scenario is built around.
  • At this operating point the engine returns 4,920 $ / hr for cost per downtime hour.
  • At this operating point the engine returns 27,720 $ for variable filtration downtime cost.
  • At this operating point the engine returns 1,800 $ for fixed restart and cleanup cost.

How this compares with the baseline

  • Against the tool's baseline example, where affected production share sits at 100% and the headline result is 27,000 $, this scenario comes in 9.33% above the baseline at 29,520 $.
  • It computes the total dollar cost of a filtration or dust-collection outage by combining the value of lost production hours with the fixed restart and cleanup cost. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Total filtration downtime cost: 29,520 $ (headline result)
