Description
Filter tester is suitable for research institutions in the pre-commercialization testing of air filtration products. It is also widely used in face mask and air filter manufacturing industries for quality control and sample testing.
Filter 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. Data can be saved automatically and also test reports can be printed by an installed printer on the machine.
Filter 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.
