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.

A control damper for an air-handling unit comprising:
- a main body rotatable about a first rotational axis;
- a first sealing element extending radially outwardly from a first side of the main body, the first sealing element formed from a resilient material;
- and
- a first lip extending outwardly from a distal end of the first sealing element, the first lip having a first series of undulations formed in an outer edge thereof.
An arrangement for a housing of an air-handling unit:
- a first control damper disposed in a passageway of the housing and rotatable about a first rotational axis, the first control damper having a sealing element extending radially outwardly from the first rotational axis in a first direction, wherein the sealing element includes a resilient lip having a series of undulations formed therein;
- and
- a second control damper disposed in the passageway and rotatable about a second rotational axis, the second rotational axis parallel to the first rotational axis, the second control damper including a seal face extending radially outwardly from the second rotational axis in a second direction, the second direction opposite the first direction.
An arrangement for a housing of an air-handling unit:
- a first control damper disposed in a passageway of the housing and rotatable about a first rotational axis, the first control damper having a first sealing element extending radially outwardly from the first rotational axis in a first direction, wherein the first sealing element includes a first resilient lip having a first series of undulations formed therein;
- and
- a second control damper disposed in the passageway and rotatable about a second rotational axis, the second rotational axis parallel to the first rotational axis, the second control damper including a second sealing element extending radially outwardly from the second rotational axis in a second direction opposite the first direction, wherein the second sealing element includes a second resilient lip having a second series of undulations formed therein.
