Automated Filter Test model 3160 is the most advanced system available for challenging filters media with sub-micrometer aerosols. It can be used to test both low and high efficiency filters and filter media up to 99.999999% efficient or penetrations down to 0.000001%。
    The model 3160 uses a bank of atomizers and the Electrostatic Classifier to challenge a filter of filter media with known-size, Mono-disperse particles. Two Condensation Particle Counters (CPCs) Simultaneously count the upstream and downstream particles and computer software calculates the penetration value. Filters can be sequentially challenged with up to 20 different mono-disperse particle sizes in the range from 15 to 800nm. The penetration value for each particle size is calculated. At the end of a test. The 3160 generates a curve of penetration Vs. particle size and produces a summary of test results. Including the most penetration particle size (MMPS). Test results can be automatically saved in a Microsoft Access data base and exported into Microsoft Excel.
      Model 3160 complies with EN 1822 Parts 3 and 5 and Provides the most complete information on filter penetration available from any filter tester. You’ll find it invaluable for product development and quality control.
