A series of four-state workshops, “Managing Your Unseen Employee: The Ventilation System,” will be held in early 2003.

Hands-on demonstrations will review setting fan controllers, adjusting inlets and the effects of static pressure and dirty fans. The demonstrations will use a mobile ventilation room and 3-4 demonstration boards featuring various brands of ventilation controllers wired to small fans and lights to simulate heating systems.

The classroom sessions will cover the basics of ventilation systems, effective temperature requirements and troubleshooting tools and techniques.

Faculty from South Dakota State University, Iowa State University, University of Minnesota and University of Nebraska will provide instruction. Dates and locations are:
