ISO-29463 Mask Particle Filtration Efficiency ( PFE ) Test Machine
Mask filtration efficiency tester is suitable for testing 45% -99.9% grade filter material efficiency test, and the filter material is tested according to international standards. The design structure of the whole tester is compact and light, and in the process of running the test, it only needs to provide additional suitable power and compressed air (no water, no oil), suitable for use in laboratories, factories and other occasions.
In the filter paper test, the particle counting method is used to measure the counting efficiency. It is recommended to use monodisperse aerosol in the test. The pressure drop measurement should be performed at the specified filtration rate.
Fix the filter paper on the fixture, and the test air volume corresponds to the required filter speed. The aerosol generated by the aerosol generator is adjusted, then electrostatically neutralized (PSL), and then evenly mixed with the filtered test air, and then enters the test area to penetrate the filter material.
In addition, the resistance of the filter material during the test must be measured and the flow rate adjusted manually.

ISO-29463 High-efficiency filters and filter media for removing particulates from the air
1. Aerosol generator
It is mainly used for experiments requiring high-concentration aerosols. It uses 0.3um PSL standard particles. The size of the main particles emitted is ≥0.3um, accounting for more than 70% of the total. It can produce aerosols continuously and stably. Provide the test particles upstream of the filter material.
2. Particle Counter
It is mainly used to monitor the upstream and downstream particle concentration of the measured filter material to obtain the efficiency of the measured filter material.
3. Differential pressure sensor
It is mainly used to test the pressure difference (or resistance) of the tested filter material under a certain test flow rate.
4. Stainless steel fixture
It is mainly used for the compression and sealing of the tested filter material.
5. Imported air pump
Mainly used for the test flow through the filter material, the flow is stable, green and energy saving, and the vibration noise is small.
6. Electrical control and software
Equipment circuit control and operation, software calculation and data processing, upstream concentration stability judgment, operation control, parameter setting.
