Theoretical and Experimental Aspects of Designing Media and Filters for Air Filtration

Course: Half Day, 0.4 CEUs
T. J. Ptak – Instructor

The objective of this course is provide information on designing filter media and filters for a broad range of air filtration applications. It is designed for engineers and technical people who are involved in designing, manufacturing and selling filter media and filters. Course covers both, the theoretical and experimental aspects of designing process as well as synergy between filter media development and filter development.

Attendees will develop a better understanding of air filtration theory when applied to filter media and filters, and how other filter requirements such as environmental regulations, durability and manufacturability have an impact on filter media design. The theoretical principles and practical knowledge gained during this course will allow to properly design filters and filter media and specify filter media for specific applications.

Course Outline:

  • Basics of filtration theory
  • Filter media including:
    • nanofiber technology
    • electrostatically enhanced media
    • media with antimicrobial properties – potential claim issue
  • Air filters including filters with external electrostatic field
    • specific filter requirements having impact on media design
    • theoretical and practical aspect of filters with external electrostatic field (high voltage)
  • Experimental evaluation of filter media and filters
    • test methods and their limitations
  • Environmental regulations and their impact on media and filter design
