General Aire 727-4 Drum Assembly
The 727-4 drum assembly is a replacement part for the model 747 and 747L GeneralAire humidifiers. This product consists of a plastic drum, covered in an evaporator sleeve. The assembly sits in a water pan, slowly spinning and picking up water, which is converted into humidity and circulated into the air in your home or business. The drum does not need to be replaced unless there is excessive mineral build-up, or it is damaged, in which case it should be replaced immediately.
