TSI 3160 Certitest Automated Filter Tester


Automated Filter Tester Model 3160 determines the pressure drop and fractional efficiency at different particle sizes (15 to 800 nm) in order to obtain the most penetrating particle size (MPPS) of HEPA and ULPA filters and filter media. It is designed to comply with the test requirements of EN 1822 parts 3 and 5. Filter tests are performed automatically following user-specific test parameters and up to 99.999999% (eight 9s) fractional filter efficiencies.



Product Details

The 3160 uses a bank of atomizers and the research grade TSI classifier to challenge a filter or filter media with known-size, monodisperse particles. Two new generation Condensation Particle Counters (CPCs) simultaneously count the upstream and downstream particles while the software calculates the penetration value. Filters can be sequentially challenged with up to 20 different monodisperse particle sizes in the range from 15 to 800 nm. The penetration value for each particle size is obtained. At the end of a test, the model 3160 generates a curve of penetration vs. particle size and produces a summary of test results, including the MPPS.

HEPA and ULPA filters are used in hospitals, operating rooms, laboratories, cleanrooms and other places that require low concentrations of particles, bacteria, etc. They are characterized by their retention at the most penetrating particle size (MPPS).
