The single blade is designed to fully cover the opening of the damper when closed. Round control dampers can be built with multiple blades, like any square damper, but the common design is a single round blade positioned in the center of the frame. With a few tweaks in design, round dampers can balance air pressure, direct airflow in one direction, and even contain the spread of smoke through ductwork. Round dampers can fulfill the role of any other damper in your HVAC system. Blade seals can be placed in one of two places: on blade stops set within the frame or along the rim of the blade itself. The single round blade is designed to fully cover the opening when rotated to close. This mount type would not be practical for multi-blade round dampers. Internally mounted actuators would interfere with the single blade. The actuator will not be mounted inside the damper. Install an actuator onto the frame to control the rotation of the blade, like a traditional square or rectangular damper. Round frames will have jambs to conceal the axle. The driving axle will protrude from the frame. The blade axle will be situated at the center of the damper’s frame. The single blade axle will run through the center of the blade. Round dampers can have multiple blades, but they will typically have a single flat blade. Round dampers are built with cylindrical frames that house the damper’s blades. They are commonly referred to as spiral ducts, which comes from the spiral-forming process used to manufacture the ducts. Round ducts are typically circular in shape, forming cylinders that carry airflow across your HVAC system. You have options for your spiral ducts!ĭucts aren’t always square or rectangular. In this article, we review the many types of round dampers and how they work.
