The GeneralAire 747L Humidifier has been DISCONTINUED BY GENERALIRE! This product is no longer available Air Quality is only a concern outdoors, correct? Wrong, the air inside your home can be even more of a concern to your health and comfort especially in the winter, which is why it is important to have a GeneralAire 65 power humidifier in your home. The GeneralAire 747L Duct-Mount Humidifier is an outstanding choice for humidification. Heated air in the system duct absorbs moisture as it passes across and through a water-soaked, drum-mounted evaporator sleeve on its way to the living area. The drum-mounted evaporator sleeve picks up moisture as it slowly rotates in a water reservoir. A float valve controls the level of water in the reservoir. Application: Perfect choice when plenum mount is not possible. Drum-type humidifier mounts in any 16" wide horiz. warm air duct. (May be installed in 12" duct; output reduced.)

• Unit Size: 12" wide x 16" high x 4" deep
