(RSBS) Round Single Blade Sealed

RSBS spec sheet (PDF)

The RSBS is our round single blade sealed damper designed to fit inside pipes sizes ranging from 6″ to 20″ round. The welded 2″ deep damper frame is undersized 1/4″ for ease of installation.

The damper blades are formed 16ga galvanized and are attached by a 1/2″ round axle and a control rod.

To keep leakage to a minimum we have installed neoprene gasket to the frame for the damper blades to seal up tightly against.

This damper can be operated by either a hand quadrant with standoff or an actuator.
