At a given rotational speed and fan pressure, centrifugal fans will develop a constant volume of airflow. Due to uncertainties in the final layout and construction of the ductwork, combined with the prospect of critical or changing process needs, many fans are selected to deliver more pressure and flow than what the industrial process or air-conditioning system actually requires. Some sort of control must then be employed to reduce the airflow to the desired level. In this self-guided course, you will explore common methods used for varying the flow capacity of the fan, such as speed control, outlet dampers, inlet dampers and inlet vane control. Your knowledge of these methods will allow you to accurately estimate and compare the power among the different methods. With this skill you can accurately predict the possible savings of changing to a more efficient method. Includes pdf course notes that are handy for future reference, and make it easier for you to follow along, especially if English is not your first language. Explore or re-visit topics in the sequence you desire. Learning activities and quiz questions keep you engaged in the topics. SI and IP units. Includes IP - SI spreadsheet calculator for unit conversion. Allow at least 2 hours in your schedule for completing this course. You can leave the course and the system will save your progress for when you come back.   Instructor: Ron Wroblewski  Course length: 2 hours  PDH credits: 2 Read more

Numerous studies of airflow and performance characteristics of circulating fans have been undertaken. Relatively few, however, are focused on aerosol transmission of airborne pathogens in large industrial spaces, a shortage all the more noticeable during the coronavirus disease 2019 (COVID-19) pandemic. To contribute to and improve the body of COVID-19-prompted guidance for the operation of circulating fans, Air Movement and Control Association (AMCA) International commissioned numerical-simulation studies of airborne-particle and aerosol transmission with large-diameter (greater than 2.1 m [7 ft]) ceiling fans (LDCF). The focus of the studies was warehouses in the United States, in which LDCF commonly are used for comfort cooling and destratification. The results, however, also are applicable to many manufacturing/industrial facilities. Join us for an in-depth look at this study, the research team, study results and ongoing guidance.  Due to the content of this webinar PDH credit is not available. This webinar was originally broadcast on January 5, 2022.   Speakers: Michael Ivanovich, Christian Taber, Dr. Paul Raftery, Dr. Leon Wang  Recording length: 60 minutes PDH credits: 0 Read more

Early in 2024, AMCA announced the release of a significant update of AMCA Publication 512, AMCA Listing Label Program. The AMCA Listing Label Program provides follow-up service for louvers tested in accordance with ANSI/AMCA Standard 540, Test Methods for Louvers Impacted by Wind Borne Debris, and/or ANSI/AMCA Standard 550, Test Method for High Velocity Wind Driven Rain Resistant Louvers. Join us for this 60-minute webinar to learn about notable changes to AMCA Publication 512 as well as changes to ANSI/AMCA Standard 540 and ANSI/AMCA Standard 550 made during the documents’ latest revision cycles and how they affect AMCA members.
