The 24V 1.7MHz Ultrasonic Atomization Driver Board + 20mm Knurled Edge Mist Maker Kit is a high-output, industrial-grade misting solution designed for humidifiers, diffusers, and misting systems requiring substantial mist volume. It combines a 20mm knurled-edge ceramic atomizer disc with a 24V driver board operating at 1.7MHz, delivering up to 300ml/h of fine mist — significantly higher than standard 5V atomizer modules.
At the heart of the kit is the 20mm knurled-edge ceramic atomizer disc. The knurled edge design provides a larger surface area for water contact and more efficient atomization compared to standard flat-edge discs. Operating at 1.7MHz, the disc vibrates at high frequency to break water into fine mist particles, producing a consistent, high-volume mist output suitable for medium to large spaces.
The 24V driver board provides the higher voltage and power required to drive the atomizer at full output. This makes the kit suitable for continuous-duty applications where higher mist volume and reliable long-term operation are essential. The driver board includes built-in protection circuits to ensure safe operation and long component life.
The 300ml/h mist output is a key advantage of this kit. Compared to standard 5V atomizers that produce 100–200ml/h, this 24V kit delivers up to 300ml/h, making it suitable for:
-
Commercial humidifiers — Larger spaces and continuous operation
-
Aromatherapy diffusers — High-volume scent distribution
-
Greenhouse and grow room misting — Humidity control for plants
-
Industrial misting — Cooling and dust suppression
-
Display and exhibit misting — Visual effects for showcases
The kit includes the 20mm knurled-edge atomizer disc and the 24V driver board, with wiring for easy connection. The atomizer disc is designed for continuous operation when properly immersed in water, with a typical lifespan of 3000–5000 hours.
The kit is widely used in commercial humidifiers, aromatherapy diffusers, greenhouse misting systems, industrial cooling, display effects, and DIY misting projects. It is also popular in product development for appliances and environmental control devices.
Important Note: The atomizer disc must be fully immersed in water during operation. Do not operate the atomizer dry, as this will cause overheating and permanent damage. Use clean water (preferably distilled) to prevent mineral buildup on the disc. The driver board should be kept dry and away from water. The 24V power supply must be capable of delivering sufficient current for the driver board.
Whether you are building a commercial humidifier, designing a high-output diffuser, or adding misting effects to a display, the 24V 1.7MHz Ultrasonic Atomization Driver Board + 20mm Knurled Edge Mist Maker Kit provides a reliable, high-performance solution. It is suitable for individual makers, engineers, and businesses purchasing in bulk for product development or industrial applications.
