Dust Protection Cost at 58% points needing upgrade: a worked example

Suppose points needing upgrade falls to 58%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate the cost of dust ingress protection on mining vehicles, including cab sealing, filtration, and positive-pressure systems for respirable silica control.

The inputs for this scenario

  • Sealed enclosures and filters: 24 units (held at the documented default)
  • Cost per sealing point: 320 $/unit (held at the documented default)
  • Points needing upgrade: 58 % (the input this scenario stresses; the baseline uses 80)
  • Pressurization system charge: 4,500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Dust protection cost = sealing points x cost per point x upgrade share % + pressurizer.
  • Total dust protection cost works out to 8,954 $ at these inputs, and this is the headline figure for the scenario.
  • Dust protection cost per unit works out to 373 $ / piece at these inputs.
  • Variable dust protection cost works out to 4,454 $ at these inputs.
  • Fixed dust protection cost adder works out to 4,500 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where points needing upgrade sits at 80% and the headline result is 10,644 $, this scenario comes in 15.87% below the baseline at 8,954 $.
  • It computes the total dust protection cost as sealing points multiplied by cost per point and the upgrade share, plus a fixed pressurization system charge. 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.

Results at a glance

  • Total dust protection cost: 8,954 $ (headline result)
  • Dust protection cost per unit: 373 $ / piece
  • Variable dust protection cost: 4,454 $
  • Fixed dust protection cost adder: 4,500 $
