Designing Dust Hoods for Better Dust Containment

​EArn 2 Contact Hours

There are many factors to consider in selection and design of dust hoods.  Particle momentum issues require much greater attention to details of dust hood design.  This two hour webinar will review the types of hoods commonly used and the process/dust collection interface issues, particle characteristics, and environmental conditions to address in hood design.  Videos will aid the participant in visualizing how hoods work and some of the more common interferences.

Prerequisite: Familiarity with industrial ventilation hood design principles.




Planning on Group Training with additional participants?

Please note AIHA's eLearning Program will require the submission of an online evaluation and $35 processing fee for any additional participant seeking credit.

Learning Outcomes

Upon completion, participants will be able to:

  • ​List the common types of dust hoods and their applications

  • Discuss the common process interface, particle characteristics, and environmental conditions that negatively impact hood performance

  • ​Estimate hood air volumes and static pressures

  • ​Outline maintenance practices to keep the hoods performing long term
