Dampers
Volume control and back-draft dampers for round and rectangular ducts
Dampers balance an HVAC system. Volume control dampers set the right airflow in each branch, and back-draft dampers stop air flowing backwards when a fan stops.
All dampers are available for round and rectangular ducts in standard and custom sizes, with manual or motorised operation.
