Industrial Filtration, Separation & Dust Collection worked example

Maintenance Interval at 18% access and cleanup allowance: a worked example in industrial filtration, separation & dust collection

This worked example runs the maintenance interval numbers for a tougher week than the baseline: 18% access and cleanup allowance instead of the typical 25%. Estimate filtration maintenance interval from required service work, maintenance crew rate, and access or safety allowance.

The inputs for this scenario

  • Filtration service work content: 120 tasks (held at the documented default)
  • Maintenance crew processing rate: 18 tasks / hr (held at the documented default)
  • Access and cleanup allowance: 18 % (the input this scenario stresses; the baseline uses 25)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base maintenance interval time = filtration service work content รท maintenance crew processing rate.
  • Adjusted maintenance interval works out to 7.87 hr at these inputs, and this is the headline figure for the scenario.
  • Base maintenance interval time works out to 6.67 hr at these inputs.
  • Access and cleanup allowance works out to 18 % at these inputs.
  • Maintenance crew processing rate works out to 18 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where access and cleanup allowance sits at 25% and the headline result is 8.33 hr, this scenario comes in 5.6% below the baseline at 7.87 hr.
  • Use it when planning a dust collector PM window, sizing a shutdown, or quoting service labor for a baghouse or cartridge unit. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
