Abstract
A control damper for a housing of an air-handling unit includes a rigid main body rotatable about a first rotational axis. A sealing element extends radially outwardly from a first side of the rigid main body. The sealing element is formed of a resilient material. The sealing element further includes a resilient lip extending outwardly from a distal end thereof. The lip has a first series of undulations formed in an outer edge thereof, wherein the undulations form a wave-shaped profile in the outer edge of the lip.
