90/190/86 Drum Humidifiers

Most Water-Conserving Whole-House Humidifier

A Drum Humidifier’s output is controlled by the humidistat, which monitors the home’s relative humidity and activates or deactivates the unit accordingly. Inside the humidifier, a rotating evaporator pad (or drum) lifts water from the water pan into the air stream, which is warmed and circulated by the furnace blower.

Because Skuttle Drum Humidifiers rely on forced air, they are well suited for warm-air heating systems, including gas, gas high-efficiency, electric, heat pump, geothermal, solar and oil forced air systems.
