General Aire 81-22 Drum Assembly
The 81-22 drum assembly is a replacement part for the model 81 GeneralAire humidifier. This product consists of a plastic drum covered in an evaporator sleeve with a metal shaft through the middle. The assembly sits in a water pan, slowly spinning and picking up water, which is converted into humidity and circulated into your home. 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.
