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
