What do you need to know about duct dampers?What do you need to know about duct dampers?In any system, the damper dimensions must be appropriate for the designed airflow volume. The consulting engineer who designs a system’s duct work typically calculates damper sizes as part of the overall air distribution system.Dampers and Actuators Catalog - Johnson Controlssp.info How are parallel and opposed blade dampers different?How are parallel and opposed blade dampers different?The flow characteristics of parallel and opposed dampers are different; an opposed blade damper must be opened further (creating a higher modulating pressure drop) to provide the same percentage of total air volume as a parallel damper (creating a lower modulating pressure drop).Dampers and Actuators Catalog - Johnson Controls
Which is better bronze or synthetic damper bearings?Which is better bronze or synthetic damper bearings?Damper bearings are important components of the damper construction and are available in different materials. Be sure to check the temperature rating requirements of the dampers on your job. Bronze bearings have higher temperature ratings and typically last longer than synthetic bearings.
