Inline penetration test concerning the quality of the filter material directly during production

Still have questions?


The P-MFP inline 2300 enables 100 % control of flat filtration media without influencing it. Based on the measuring principle of single particle measurement, aerosol photometer, aerosol generator and a custom-made measuring carriage become the P-MFP inline 2300. This allows penetration/filter efficiency, as well as pressure drop and breathing resistance to be measured at 100 % of the material, thus providing a statement on quality. In manufacturing and processing plants, this data can also be used to control processes. It is also possible to use the P-MFP inline 2300 as a "stand-alone" solution and thus perform outgoing and incoming goods inspections.

In the P-MFP inline 2300, the belt material is fed through a custom-made carriage and exposed to salt aerosols via an aerosol generator. This is medical-grade salt aerosol with an extremely low mass concentration. This prevents the belt material and its filtration properties from being affected. The aerosol spectrometer measures the aerosol concentration before and after the filtration medium, thus measuring the filter efficiency. Differential pressure sensors are also used to measure the pressure difference, which allows conclusions to be drawn about the breathing resistance.

Depending on the application, the P-MFP inline 2300 can be implemented directly in the production line or as a separate measuring station. Thus, it is possible to qualify 100 % of the strip material.
