Course Objective
This course provides an extensive understanding of air filter design and filtration systems. It explores the fundamental mechanisms of particle capture, covering concepts such as interception, inertial impaction, diffusion, and electrostatic attraction. Additionally, the course lays a solid foundation in aerosol science, including topics like particle diameter, size distribution, shape, and relevant testing standards.
Participants will learn to analyze and quantify key metrics, including filtration efficiency (the ability to capture particles of different sizes), pressure drop (the resistance to airflow), and filter lifespan. The course also examines how design selection affect these performance parameters, such as filter media type, filter surface area, filter geometry (Flat, bag, pleated and cartridge), particle characteristics, airflow velocity, operating and climate conditions.
This course is designed to equip participants with the knowledge to analyze existing filter designs, understand the trade-offs between different performance metrics, and effectively monitor filter performance for optimal outcomes.
