Automated Filter Tester 3160

Request A Quote Accessories Related Products

The model 3160 determines the pressure drop and fractional efficiency at different particle sizes 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.

HEPA and ULPA filters are used in hospitals, operating rooms, laboratories, clean rooms and other places that require low concentrations of particles, bacteria, etc. They are characterized by their retention at the MPPS.

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 800nm. 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 most penetrating particle size (MPPS).

  • Does TSI design custom filter holders?
    TSI does customer filter holder designs when needed. Our standard filter holder is designed for flat sheet media. This standard holder is also used to make gravimetric samples with our special gravimetric sample holder, and to use with a pressure plate. Generally, custom filter holder designs are less expensive for round canisters and more expensive for rectangular cartridges, depending on the design and machining requirements. Consult TSI with filter types to be tested for exact pricing on this. To get exact pricing, we need to either have a filter on hand or have the customer send us a sample filter.
  • What data is output through the RS-232 interface?
    The RS-232 interface outputs the filter's percent penetration, flow rate, and pressure drop in the standard filter test modes of operation. The loading test mode of operation also outputs the upstream photometer reading.
  • What is DOP?
    The actual name for DOP is dioctyl phthalate.
