AprilAire 700 Whole-House Humidifier – Automatic – Large Capacity Fan-Powered Furnace Humidifier for Homes up to 4,200 Sq. Ft.

A built-in fan on the Model 700 power humidifier pulls heat directly from the furnace. The Model 700 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. AprilAire introduced the first evaporative humidifier for forced air furnace systems back in 1954. Since that time, AprilAire continues to lead the industry in whole home humidification systems. Our evaporative humidifiers work by piping water into the distribution tray located at the top of the humidifier. The water is uniformly distributed across the width of the tray and through a scientifically designed system of outlets. It flows by gravity over the Water Panel evaporator. Dry, hot air from the HVAC system is moved through the moisture-laden Water Panel evaporator. Natural evaporation takes place, the water is turned to vapor, and the humidified air is circulated throughout your home. INCLUDED IN THE BOX: Installation instructions and template, humidifier with built-in fan, 24 VAC transformer, automatic digital humidifier control with sensor, outdoor temperature sensor, saddle valve, solenoid valve, and Model # 35 Water Panel
