The filter test rigs PMFT System enable the reliable control of masks and filter material. This allows you to ensure the quality of your products effectively.

The PMFT system includes three models for different needs:

  • PMFT 1000 for development and production monitoring of half masks
  • PMFT 1000 M for reliable continuous operation in routine monitoring of half masks
  • PMFT 1000 F as an all-rounder in the testing of almost all mask and filter types
The PMFT System measures overall penetration and breathing resistance/pressure drop and fractional efficiency in the size range between 100 nm and 5 μm.
Our test instruments test better than required by relevant standards for face masks and full face mask filters:
