"Nilfisk SC500 Solution Filter — Replace & Clean"
Clean or replace the Nilfisk SC500 solution filter when flow drops. Shop filter assemblies and keep the SC500 dispensing consistently.

Replacement Part Guide
Use this guide to inspect, replace, and stock the right wear item for your SC500 route. Order the matching part below or view the full machine if you are adding a scrubber to your fleet.
When the SC500 stops dispensing solution evenly, the solution filter is a common culprit. Sediment and chemical residue clog the filter and starve the brush area.
Daily care
- Rinse the filter screen when you dump and rinse the solution tank.
- Use approved neutral cleaners at correct dilution to reduce scale buildup.
When to replace
- Replace the filter assembly if flow remains weak after cleaning.
- Stock at least one spare filter if the machine runs multiple shifts.
