AprilAire: Model 400MK Evaporative Bypass Humidifier
AprilAire Model 400MK evaporative bypass humidifiers use 100 percent of the water that goes into the system by capturing excess water in a reservoir. The humidifier contains a water panel that absorbs the water from the reservoir. The water is then heated into a vapor and dispersed throughout the home before more water is added to the reservoir, helping save money on water and utility costs.
The unit delivers up to 17 gallons of moisture to a home per day. A manual humidistat is provided with all 400MK models, for applications where an automatic control is not practical. Installation kit included.
