Palas - Model PMFT 1000 F -Respiratory Protection Particle Filters System
PMFT 1000 F as an all-rounder in the testing of almost all mask and filter types. Test of total penetration better than the standard, exact analysis of filter mask efficiency from 145 nm to 5 µm.
The PMFT 1000 F tests respiratory protection particle filters better than the standards EN 143, ISO 16900-3 and NIOSH 42 CFR 84 with additional accurate analysis of filter mask efficiency for SARS-CoV-2 (size approximately 120 nm to 160 nm). In addition, the testing of face masks based on the EN 149/ISO 13274-7 standards is possible. Both total photometric penetration and fractional efficiency are tested e.g., the efficiency in the whole size range respectively the particle size-dependent penetration.
The PMFT 1000 F 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. Corona discharge with CD 2000 A is integrated.
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 aerosol photometer Promo LED 2300. An automatic switch allows efficiency measurements without dilution up to 99.9995 %.
The size distribution of the test aerosol according to the standard is as follows:
EN 143
Oil: Media diameter ca. 160 nm | Geom. standard deviation ~ 2
Salt: Media diameter ca. 60 nm | Geom. standard deviation ~ 1.9
Oil: Media diameter 190 nm | Geom. standard deviation 1.4 - 1.8
Salt: Media diameter 80 nm | Geom. standard deviation 1.4 - 1.8
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 the particle penetration via the particle size, the PMFT can also be used to consider the tolerances in the particle size distribution according to EN 13274-7 as min. / max. penetration value.
