Quick Overview
Details on the Aprilaire 400 Humidifier
Automatic waer saver Furnace Humidifier. The Model 400 is a drain-free humidifier, featuring evaporative technology to minimize water use. 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.
