Dampers (also known as louvers) are essentially an assembly of plates designed to control the ventilation in duct work systems. Sweco Fab. can design and manufacture standard, heavy duty, manually operated or motor-driven dampers. We can also install refractory lining to withstand high temperature applications. Air intake stacks are used to keep debris from traveling to the duct.
