Benefits

  • Test rig working principle better than 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
  • Meets the requirements for respirators specified by the CCF (Covid Certified Filter) quality seal
  • Includes two aerosol generators for NaCl and for oil
  • Testing of fractional efficiency, e.g., efficiency in whole size range of 145 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). Efficiency also displayed at 145 nm
  • 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 test of breathing 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 two years maintenance package for availability of test rig
  • Can be operated as Mas Q-Check with optional Mas-Q-Head

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 M tests face masks 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.

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). 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.

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

EN 143 Particle Distribution.jpg

ISO 16900-3

Oil: Media diameter 190 nm | Geom. standard deviation 1.6
Salt: Media diameter 80 nm | Geom. standard deviation 1.6

ISO 16900-3 Particle Distribution.jpg

42 CFR 84

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.
