Filter Tester

FNM Filter Testers (FT150PA, FT200PO and FT200PS) can determine the efficiency, pressure drop and air permeability of different flat sheet filter media/respiratory mask using oil, salt aerosols or atmospheric dust. Our filter/respiratory mask testers can be employed for testing different flat sheet media which are used for producing respiratory face masks and air filters.

Filter/respiratory mask testers are equipped with high precision particle counter (six-channel particle sizes: 0.3, 0.5, 1.0, 2.5, 5.0 and 10.0 µm) for counting the particles generated by oil / salt particle generator or atmospheric dust in order to calculate filtration efficiency. Additionally, this machine can calculate air permeability and pressure drop of flat sheet media automatically.
FT200PO and FT200PS use two particle counters that simultaneously count upstream and downstream particles. Data can be saved automatically and also test reports can be printed by an installed printer on the machine.
FNM filter/respiratory mask testers can measure the efficiency and pressure drop of flat sheet media according to BS EN 143, BS EN 149, BS EN 779, ISO 16890, ISO 16900-3, ISO 11155-1 and ISO 5011 standards.
