Flat Filter or Plug-in Filter? – The Difference with SATA RPS Cups
Anyone who regularly works with SATA RPS cups knows: the right paint filter is essential for a clean, even finish. But many people ask themselves: flat filter or plug-in filter – which one is the better choice?
1. Function of the Filters
- Filter out particles and lumps from the paint
- Ensure a consistent material flow
- Prevent nozzle clogs and rework
2. Flat Filter
Flat insert that is placed into the lid.
- Quick to change – ideal for frequent color changes
- Easy to dispose of / clean
- Better suited for low-viscosity materials or pre-filtering
3. Plug-in Filter
Inserted firmly into the lid and sits securely.
- Secure fit, even with high-viscosity materials
- Lower risk of unfiltered material passing through
- Ideal for high-quality final finishes
4. Which Mesh Size?
Typical: 125 µm (finer) for low-viscosity paints, 190 µm (coarser) for higher viscosity.
Conclusion
Flat filter = fast and flexible. Plug-in filter = stable and precise. The best choice depends on the material, workflow, and quality requirements.
