Palas - Model PMFT 1000 -Protective Mask Test Systems
PMFT 1000 for development and production monitoring of half masks. Test of total penetration better than the standard, exact analysis of filter mask efficiency from 100 nm to 3 µm.
The PMFT 1000 tests respirators better than the standards EN 149/EN 13274-7 with additional accurate analysis of filter mask efficiency for SARS-CoV-2 (size approximately 120 nm to 160 nm). Both total photometric penetration and fractional efficiency are tested e.g., the efficiency in the whole size range respectively the particle size-dependent penetration.
In addition, the PMFT 1000 meets the requirements for respirators specified by the CCF (Covid Certified Filter) quality seal .
The PMFT 1000 is equipped with aerosol generators for measuring penetration with oil and salt. Measurement procedures for quick quality control (short test) or for testing according to standard (exposure test) are supplied.
Operation and automatic printout of the measurement results are therefore easy even for inexperienced users.
The measurement of total penetration and penetration via particle size is carried out with the high-precision Promo 1000 aerosol photometer.
The size distribution of the test aerosol according to the standard is as follows:
EN 149
Oil: Media diameter 290 nm | Geom. standard deviation 1.85
Salt: Media diameter 70 nm | Geom. standard deviation 2.5
Oil: Media diameter 200 nm | Geom. standard deviation 1.6
Salt: Media diameter 55 nm | Geom. standard deviation 1.86
Based on the measurement of particle penetration via particle size, the PMFT can also be used to view the tolerances in the particle size distribution according to EN 13274-7 as min. / max. penetration values. In addition, comparative values to other manufacturers are possible (option).
The comparison with other standards (42CFR84/NIOSH) is also easy with the 42CFR84 upgrade KIT.
