PHASE I • Introductory Ventilation System Design This class is intended for participants who have responsibilities for ventilation system maintenance or oversight of ventilation system projects. Participants who have had limited prior experience or specific education in ventilation system design or who do not design ventilation systems regularly are also recommended to attend this class.

PHASE II • Advanced Ventilation System Design Participants selecting this class should be thoroughly familiar with exhaust system design procedures or have satisfactorily completed a Phase I Ventilation System Design class at a prior conference. While not required, all Phase II registrants are encouraged to bring a computer.

Non-Standard Air Applications • This class will deal with exhaust systems that involve elevated air temperatures and/or moisture where air density may vary significantly from standard conditions.
