OBN – Opposed Blade Non-Sealed Balancing Damper

The OBN non-sealed balancing dampers offer a sturdy steel construction. The damper frame is a 16ga galvanized welded hat channel design to keep the damper square and true to form. The blades are formed 16ga galvanized 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.
