The 16mm 108KHz Ultrasonic Atomizer Disc is a high-quality replacement component designed for humidifiers, foggers, and misting devices. It features a 16mm ceramic ultrasonic disc that operates at 108KHz, delivering reliable atomization performance in a compact form factor. The disc comes pre-wired with 60mm leads and includes a 20mm sealing O-ring, making it a complete drop-in replacement solution for compatible humidifier and fogger units.
At the heart of the disc is a ceramic piezoelectric element that vibrates at 108KHz when driven by an appropriate driver circuit. This high-frequency vibration breaks water into fine mist particles, producing a consistent, visible mist output. The 16mm diameter makes this disc suitable for compact humidifiers, portable misters, and small fogger units where space is limited.
The 12V operating voltage is a key feature of this disc. Unlike standard 5V atomizers, this disc is designed for 12V driver circuits, which are commonly used in automotive, industrial, and larger humidifier applications. The higher voltage allows for efficient atomization with good mist output in a compact disc size.
The pre-wired 60mm leads simplify installation and replacement. The leads are already attached to the disc, eliminating the need for soldering in tight spaces. The 20mm sealing O-ring ensures a watertight seal when the disc is installed in the humidifier chamber, preventing leaks and ensuring reliable operation.
The disc is widely used as a replacement part for:
-
Ultrasonic humidifiers — Home and commercial humidifiers
-
Fog machines — Small-scale fog and mist effects
-
Aromatherapy diffusers — Scent distribution
-
Model-making foggers — Diorama and display effects
-
DIY misting projects — Custom humidification systems
The disc is designed for continuous operation when properly immersed in water, with a typical lifespan of 3000–5000 hours. It is a consumable component that may need periodic replacement depending on water quality and usage conditions.
Important Note: The atomizer disc must be fully immersed in water during operation. Do not operate the disc dry, as this will cause overheating and permanent damage. Use clean water (preferably distilled) to prevent mineral buildup on the disc surface. Ensure the driver circuit is compatible with the disc’s 108KHz frequency and 12V operating voltage.
Whether you are replacing a worn-out atomizer in a humidifier, building a custom fogger, or maintaining a misting system, the 16mm 108KHz Ultrasonic Atomizer Disc provides a reliable, ready-to-install solution. It is suitable for individual makers, repair technicians, and businesses purchasing in bulk for product development or service applications.
