A damper assembly is configured for placement within a duct of a ductwork system that supplies conditioned air through a register boot to a register vent. The damper assembly includes a damper that is configured to articulate from a deployment configuration, which facilitates advancement of the damper through the register boot and into the duct, to an operational configuration, in which the damper is positioned within the duct and able to selectively control how much conditioned air being supplied through the duct is permitted to pass by the damper and exit the register vent. The damper assembly includes an elongated deployment member that extends from the damper and is configured to facilitate advancement of the damper through the register boot and into the duct.

A damper assembly for use in a round forced air duct feeding a register vent through a register boot includes a damper frame having a frame periphery with a first side and a second side that is at least substantially parallel with the first side, the first side and the second side each having a length that is greater than a distance between the first side and the second side. A damper blade is pivotable relative to the damper frame about an axis of rotation, at least substantially parallel with the first side and the second side, between an open position and a closed position. A flexible outer seal extends outwardly from the frame periphery of the damper frame and is at least substantially circular in order to seal against an inner surface of the round forced air duct.

Retrofit damper optimized for universal installation

A damper assembly is configured for deployment in a forced air duct that supplies conditioned air through a register boot to a register vent secured relative to the register boot. The damper assembly includes a damper unit and a deployment strap. The deployment strap includes a first end secured relative to the damper unit and an opposing second end and has a length that is sufficient to position the damper unit in the forced air duct when the second end of the deployment strap is secured relative to the register boot. When in a deployment configuration, the damper unit has a reduced profile to facilitate deliver of the damper unit through the register boot and into the forced air duct. When in an operational configuration, the damper unit is configured to operate a damper blade between a closed position and an open position.

An electrode humidifier device having a cartridge and a reconfigurable steam nozzle, connected to the cartridge that may be changeable between a direct and a remote mounting. Fill and drain valves on a manifold may be operated to add or drain water, respectively, in the cartridge. A sensor may indicate a water level in the cartridge. A controller may be connected to the sensor, and the fill and drain valves. A steam output capacity of the cartridge may be maintained at a predetermined magnitude by controlling the level of water with a controller. The cartridge may have one or more handles for easily inserting or removing the cartridge in a housing. The manifold may be installed in the drain pan for easier cartridge replacement. The humidifier device may be directly mounted on an air duct of a heating system or can be installed remotely.
