Benefits
Test rig working principle better than EN 143, EN 149 and EN 13274-7
Equivalent to GB 2626, 42 CFR 84 and ASTM 2299-3 by additional software option
Test of community masks equivalent to CWA 17553
Includes two Aerosol generators for oil and NaCl
Testing of fractional efficiency, e.g. efficiency in whole size range of 100 nm up to 40 µm
Exact analysis of filter and filter mask efficiency for SARS-CoV-2 (size approx. 120 nm up to 160 nm) in the size range between 100nm and 180 nm we have 8 size channels
Future proof: Works with any kind of aerosol without adjustments
Further measurement of differential pressure, e.g. as well within different face velocities to simulate measurement of breath resistance
Face velocity adjustable between 1.5 – 70 cm/s
Product capable of fast quality assurance AND continuous optimization in R&D (display of size distribution)
Individual face mask adapter for your product
Attractive 2 years maintenance package for availability of test rig
The software extension additionally offers:
Display of penetration results of the entire tolerance range of the size distribution according to EN 13274-7
Allows the comparison of different test institutes and test systems
Facilitates certification
Shows wide range of standards. Depending on the test operation – i.e. particle size distribution of the test aerosol – one and the same mask can perform very well or fail the test
Description
The PMFT 1000 tests respirators better than the standard with additional accurate analysis of filter mask efficiency for SARS-CoV-2 (size approximately 120 nm to 160 nm). 8 size channels for 100 nm and 180 nm efficiency.
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
42 CFR 84 / GB 2626:
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.
