SMP balancing dampers are manufactured with a sturdy steel construction. The damper frame is a 16 gauge galvanized steel welded hat channel design to keep the damper square and true to form.

The blades are formed 16 gauge galvanized steel with linkage in the airstream for better blade operation. Bronze oilite bushings offer low maintenance and ease of operation.

Dampers of the same height can easily operate sectioned together by linking the blade with a connecting rod from one damper section to the blade of the next damper section. Please consult factory for best options.

Commercial Control Dampers are used in buildings to regulate the flow of air in an HVAC system.
They can be used in intake, exhaust, or mixed air applications.
