PMFT 1000 : respirators mask filter tests
Product Descriptions
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.
• 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
• Meets the requirements for respirators specified by the CCF (Covid Certified Filter) quality seal
• 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
