Round Opposed Blade Sealed (ROBS) Damper

Sheet Metal Connectors is proud to distribute and sell Standard Metal Products dampers and louvers.

The Round Opposed Blade Sealed (ROBS) Damper is designed to fit inside pipe sizes ranging from 16 to 48 inches round. The welded 2-inch deep frame is undersized by a quarter inch for ease of installation, and damper blades are a formed 16-gauge galvanized steel with linkage in the airstream for better blade operation. To keep leakage to a minimum in Round Opposed Blade Sealed Dampers, SMP installs spring stainless steel to the side jambs, BES vinyl seals on the blades and neoprene gasket on the frame for the curved edge of the blade to seal up tightly against.
