Fan Array Vibration Isolation in Air Handling Units

The rules have changed for vibration isolation of modern air-handlers with fan arrays. Current ASHRAE design guidelines for fan vibration isolation in air handling systems are based on applications using single belt-driven fans. But many air handling systems now use arrays of direct-drive fans which have different vibration characteristics and thus different vibration isolation requirements. Design guidelines for vibration isolation of single fans don’t work for fan arrays—arrays of multiple direct-drive plenum fans require a new approach to vibration isolation.

What you will learn


This webinar will identify the deficiencies of the current ASHRAE design guidelines for fan vibration isolation as applied to arrays of direct-drive fans. We’ll look at:

  • Methods and effectiveness of internal and external vibration isolation ranging from solid mounting to spring isolation.
  • Guidance for effective isolation of fan arrays of direct-drive fans
  • Fans with AC Induction, PM and EC motors
