Particle Filtration Efficiency Tester
New Type for NIOSH
Equipped scartting light photometer.
Equipped high accuracy flow meter and sampling pump.
Automatic caculated penetration effeciency and air flow resistance.
Equipped the eletrostatic neutralizer.
Mask particle filtration efficiency tester is professional designed to determine the particle filtration efficiency of air filter, flat
sheet filter media or filter elements. Using test aerosol, the tester can measure the fractional efficiency and pressure drop of
samples under a prescribed filter medium velocity. High level of automatic operation with stable performance and low
maintain cost makes tester widely used in quality control, research and development, certification of air filter industry, filter
manufacturing industry, respirator or mask manufacturing or testing industry, etc.
The tester can work with breath resistance tester to determine the daily protective mask performance. It also can be used to
determine air filter media’s filtering efficiency. With compact structure and easy operation system, the tester provides better
testing usage and satisfies more applications.
