In 2023, Alpha Scientific supplied Australia’s largest government research organization with a Palas PMFT-1000-F advanced filter testing system with particle counting and sizing capabilities. Palas PMFT-1000 filter and face mask testing systems are widely used throughout Australia and the world. The (-F) version of this filter testing system was the first of its type in the Southern Hemisphere and gave this group unique measurement capabilities when testing face masks, filters and other media.
The Palas PMFT 1000-F tests respiratory protection particle filters better than the EN 143, ISO 16900-3, and NIOSH 42 CFR 84 standards require with additional accurate analysis of filter mask efficiency for SARS-CoV-2 (size approximately 120nm to 160nm). In addition, testing face masks based on EN 149 / EN 13274-7 standards is possible. Both total photometric penetration and fractional efficiency are tested. For example: the efficiency over the entire particle size range, respectively, the particle size-dependent penetration.
