Description

This course provides a technical overview of how fans are tested under AMCA 210/211 standards and why those results can differ from field performance. Participants will learn to identify common "performance killers," such as poor aspect ratio inlet boxes and abrupt discharge elbows. The session highlights the physics of airflow and offers practical solutions like turning vanes and no-loss rain stacks to reclaim lost static pressure.

Instructor: James Conway
PDH: 0

Objectives

  • Identify how non-uniform airflow at the fan inlet or outlet creates pressure losses not accounted for in standard fan catalogs.

  • Apply AMCA guidelines for effective duct length to achieve fully developed flow and maximize static pressure regain at the fan discharge.

  • Contrast the aerodynamic and acoustic impacts of pre-spin vs. counter-spin vortexes and the importance of turning vanes in inlet boxes.

Certificate
