Aprilaire 400 humidifier – Comfortable humidity with minimal water usage

The newest edition in the elite line of Aprilaire humidifiers, the Aprilaire 400 humidifier with automatic digital control, maximizes humidity control through a water-conserving design that minimizes water use. The new evaporative technology enables the Aprilaire 400 humidifier to use 100% of the water delivered to the unit. This feature allows the Aprilaire 400 humidifier to operate without a drain line, making it perfectly suitable to homes with septic systems, people preferring water conservation and applications where a floor drain is not available. The Aprilaire 400 humidifier comes with a built-in bypass damper that is conveniently labeled for winter and summer settings. With a high evaporative capacity of 0.70 gallons per hour, the Aprilaire 400 humidifier is best suited to handling homes up to 4000 square feet if they are constructed tightly.

The truly automatic control and innovative design of the Aprilaire 400 humidifier allows you to operate and maintain it easily. The Aprilaire 400 humidifier can also be used in manual mode without compromising on the comfortable humidity level and the functionality of the unit. For best performance, the water panel of the Aprilaire 400 humidifier should be replaced once a year, either before the heating season starts or at its end. The saddle valve of Aprilaire 400 humidifier will need to be replaced every 5 years while the strainer and orifice should be replaced every 3-5 years as needed.

Besides automatic digital humidity control and the water-conserving design, the Aprilaire 400 humidifier also features an Aprilaire water panel, outdoor temperature sensor, self-piercing saddle valve, automatic humidistat, 24V transformer and installation instructions/plenum cut-out template from Aprilaire.
