AprilAire Model 700 Fan-Powered Evaporative Whole House Humidifier

A built-in fan on the Model 700/700M power humidifier pulls heat directly from the furnace. The Model 700/700M is the highest capacity AprilAire Evaporative Humidifier. Easy to install, it’s the best choice for systems with low or variable speed air handlers. The 700 includes an automatic digital control that delivers the correct level of humidity based on indoor and outdoor temperatures. A manual humidistat is provided with all 700M models for applications where an automatic control is not practical.
