N29

High-precision cleaning of screen-printing stencils

The benchmark machine for cleaning stencils, squeegees and print heads: dedicated ultrasonics, a closed-loop water-based bath and patented filtration.

MBtech N29 cleaning machine

Application

The N29 cleans screens and stencils of all formats, along with squeegees, holders and print heads. The water-based cleaning agent is continuously regenerated by patented filtration: the bath stays active and rinsing is done with the filtered agent — no water, no compressed air.

Benefits

  • Ultrasonics dedicated to stencil cleaning
  • Water-based bath regenerated in a closed loop
  • Patented filtration of the cleaning agent
  • Rinsing with the filtered agent — no DI water
  • Neither water nor compressed air required

Frequently asked questions

Does the N29 require deionised water?

No. The process runs in a closed loop with a water-based agent regenerated by patented filtration. Rinsing uses the filtered agent; no water or compressed-air supply is needed.

What can the N29 clean?

Screens and stencils of all types and formats, squeegees, holders and print heads, as well as boards rejected at the printing stage.
