Aprilaire All Air Conditioning Humidifier in the United States with an effective humidification area of 300 square meters

Some households have drainage facilities that are unusable or available, and the 400 series humidifiers are designed to meet these applications. The design features of the Aprilaire humidifier ensure trouble-free performance and minimal maintenance. All humidifier casing components that come into contact with water are non-metallic and will never corrode. Under normal operating conditions, neither heat nor water will affect their Water Panel evaporator, resulting in a uniform design. High evaporation and scale control plugins effectively capture mineral deposits on the Water Panel, which are often the cause of damage to the working components of ordinary humidifiers. The evaporator is the core of the humidifier and must be in good condition to ensure high capacity and trouble-free performance. Except for 400 boxes of the 400M model, at least two replacements should be made each time, and the seasonal distribution tray should be replaced once a year. The use of synthetic fiber fabric filters is aimed at evenly delivering water to the entire top surface of the "water plate" evaporator, provided that the humidifier is installed in a horizontal position. It is normal for some mineral deposits in the distribution tray to flow out between humidification cycles, as they can actually help distribute water in the tray. However, if they block the opening, they should be removed according to the instructions in the manual for regular preventive maintenance.

Digital humidification control, along with the HVAC system, controls the operation of the humidifier. This controller senses indoor humidity and outdoor temperature, and automatically adjusts the operating time of the humidifier to provide humidity at home.
