This manual provides essential information for the safe and efficient operation of your HQHAOTWU Commercial Ultrasonic Humidifier, Model 2SC-10.5. This industrial-grade unit is designed for uniform humidification in large spaces such as warehouses, greenhouses, and commercial facilities, ensuring optimal humidity levels for various applications including plant growth and dust reduction.

The humidifier utilizes ultrasonic high-frequency oscillation to atomize water into ultra-fine particles (1-5 microns), which are then diffused into the air by a pneumatic device. It features a fog volume of ≥ 10.5kg/h and offers both humidity and time control methods for precise environmental management.
