Our public webinar series will focus on helping attendees understand industrial fan basics. We will cover a variety of topics, ranging from introductory, intermediary and advanced levels based off attendee feedback. Each webinar is worth one PDH (professional development hour). An expert panel will be conducting a Q&A session at the conclusion of each webinar. If you have suggestions for future webinar topics, please contact us or your local representative.


We will resume webinars in the Fall of 2022.


Fan Fundamentals - Intermediary, Module 3 - Noise

  • Understand the calculation procedure for overall sound and frequency weighting
  • Scale sound data to alternate operating conditions
  • Adjust sound data to account for fan configuration in the field
