Page 15: Product Description
Product Description General Description The Ultrasonic Humidifier is a steam-less humidifier. To humidify the space, the Ultrasonic Humidifier creates mist using piezoelectric transducers. Mist is expelled from the unit with internal fans, and an Ultrasonic Blower Pack (if installed), into the space. Mist is then absorbed into the air. The Ultrasonic Blower Pack comes in 4 different output capacities;... -
