Product Description

The evaporator sleeve, sometimes called a humidifier pad, media filter, or water filter, absorbs water from the pad within the humidifier. The sleeve fits over the drum assembly, which slowly spins and picks up water from the pan sitting below the drum. The water is then circulated as humidity into the air. The evaporator sleeve should be replaced at least once during the heating season. This sleeve is also available as part of the GeneralAire 747 series tune up kit, which includes everything you need to make your humidifier like new, and also saves 15% versus purchasing the items individually. This part works with humidifier models 747, 747L.

This component is also known as part number: 7107

This item is sometimes called a media filter, humidifier pad or water filter. The manufacturer is sometimes referred to as General Filters, General Air but is correctly spelled GeneralAire®.

Mr. Max Leimgruber by Max Leimgruber (Demarest NJ US)

I ordered a drum assembly (sleeve already mounted) plus 2 spares. The sleeve on the drum was improperly finished and had to be replaced (parts of the mesh were sticking out and prevented the drum from rotating properly). The spare sleeve I installed worked well. Also, I had numerous sleeves in the past and all of them had always worked well.

Mister? by William L Rogers (Export Pe US)

As always, I received the right parts and they arrived "on time." Since you have given me a pulpit, I thought I would take advantage of it: I have had the humidifier that houses these filters for a long time. Successive years of operation have resulted in a buildup of calcium (probably), and other signs of aging (the humidity control does not work, etc.). I would like to replace this unit with a new one. The ductwork for our furnace has no provision for side mounting (there is no available vertical surface in the discharge system for such an application). You and your competitors only provide humidifiers which are designed for side mounting. Therefore, I am forced to try to nurse this unit along, with no chance of replacement. Within the next year or two, we will have to revert to cave-man humidification: tubs of water all over the floor. Have you considered manufacturing bottom-mounted humidifiers, like you did all those years ago?
