This GeneralAire 1137 Humidifier is a fan-powered unit that mounts easily on the warm air plenum and delivers 21.3 GPD. A portion of the heated air from the furnace passes through a water-soaked pad where it absorbs additional moisture and then returns for distribution throughout your home. Water is metered into a patented trough and dispersed uniformly across the pad. Unevaporated water drains from the bottom of the unit to eliminate mineral build-up. An MHX3 humidistat is included.
