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
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
