Ventilation and Exhaust Systems

COURSE NO: M04-009
Ventilation and Exhaust Systems
Course Highlights

This online engineering PDH course provides the basics of the ventilation system and will familiarize the reader with the mechanism of infiltration, exhaust ventilation and forced ventilation systems.


The ventilation systems supply and remove air to/from the building. In doing so, these systems control quality of breathing air and protect personnel and sensitive equipment from potentially hazardous airborne contaminants, fires, explosions, and excessive heat.


All components of ventilation systems such as fans, motors, ducts, dampers, air intakes and outlets, filters, and access panels, must work properly in order for the systems to operate safely and efficiently. Therefore, ventilation system design must be considered as an essential part of planning and development of new facility. Failure to provide effective ventilation systems in the design stage can create costly obstacles to safe and efficient operation, which ultimately presents a threat to personnel safety and health.


This 4 PDH online course is applicable to mechanical engineers, design and construction personnel, technical staff and facility personnel who are interested in gaining a better understanding of ventilation and exhaust systems.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • What is natural ventilation and what factors determine the building porosity
  • How do you calculate the infiltration using air change method, crack method, curtain wall method and stack effect method
  • What are the design considerations for forced ventilation systems
  • How are constant air volume ventilation systems different from variable air volume systems
  • What are the appropriate applications of airfoil, backward-curved, radial blade and forward-curved fans
  • What are the design principles and methods for air distribution ducts
  • What are the different types of air cleaners and air filters used for ventilation purposes
  • What are the common types of exhaust hoods and what factors determine the effective removal of contaminants
  • How do the automatic control systems function and how is economy cycle operation achieved
  • What are the basic methods and procedures for testing, adjusting and balancing (TAB) of ventilation systems
