PMFT 1000

Test of respiratory masks better than the standard. Exact analysis of filter mask efficiency from 100 nm up to 40 µm.  SARS-CoV-2 size approx. 120 nm - 160 nm.

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.

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

EN149.PNG

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.
