PFMT1000

Test of respiratory masks better than the standard. Exact analysis
of filter mask efficiency for Corona Virus, size approx. 120
nm up to 160 nm. 8 size channels for efficiency from120nm and
180 nm.

Benefits
• Test rig working principle better than GB 2626, EN 143
• Testing of fractional efficiency, e.g. efficiency in whole size range of 120 nm up to 40 μm
• Exact analysis of filter and filter mask efficiency for Corona Virus (size approx. 120 nm up to 160 nm) in the size range
between 120nm 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
• Face velocity adjustable between 1.5 - 50 cm/s
• Product capable of fast quality assurance AND continuous optimization in RD (display of size distribution)
• Individual face mask adapter for your product
• Attractive 2 years maintenance package for availability of test rig
