PMFT 4000

PMFT 1000 M: Atemschutzfiltern, Filtermaskeneffizienz
The PMFT 4000 is a versatile instrument for testing virtually all filter types. Total penetration testing exceeds the standard, and efficiency measurements range from 145 nm to 5 µm

The PMFT 4000 was specifically developed for use in the quality control of filter media and particle filters. On a test area of 100 cm², the medium is tested at a defined flow velocity ranging from 1.5 to 70 cm/s—simultaneously, the total photometric penetration and the fractional separation efficiency are determined, i.e., the efficiency across particle size or the particle-size-dependent penetration.

Testing is conducted in accordance with the standards EN 143, ISO 16900-3, and NIOSH 42 CFR 84, as well as EN 149/EN 13274-7 and GB 2626. A dedicated media test is available for HEPA-grade filter media. In addition, precise analysis of filter efficiency in the size range from approximately 120 nm to 160 nm is possible.
