Understanding the Atomizing Disc for Misting Fan Technology
When sourcing an atomizing disc for misting fan applications, buyers are typically evaluating three factors: output volume, particle consistency, and long-term operational reliability. Gd SWT Smart Tech Co., Ltd. (Dongguan Sweetsound), operating under the SWT brand since its 2002 registration, addresses these requirements through its dedicated Ultrasonic Atomization Series, a product line built on piezoelectric ceramic manufacturing expertise accumulated since the company began professional buzzer and piezo production in 1991.
The core challenge in misting fan applications is generating a stable, high-volume mist without sacrificing durability. SWT’s positioning as a professional acoustics and ultrasonic solutions provider speaks directly to this: the company specializes in the R&D, manufacture, and marketing of electronic ceramic materials, smart materials, and electroacoustic transducer components, giving it direct control over the piezoelectric substrate that determines atomization performance.
Core Product Line: Glass Glaze/Ultrasonic Atomization Sheets
Within SWT’s atomization portfolio, the Glass Glaze/Ultrasonic Atomization Sheets product line is specifically positioned for high-power nebulization, serving humidifiers, landscaping systems, and misting fan equipment. This line is engineered as a large output piezo atomizer for humidification systems, and it is also applied to farms and animal husbandry environments where sustained, high-volume misting is required.
A key structural advantage for misting fan integrators is SWT’s support for multi-head configurations, including 2, 4, 6, 8, 10, and 12 heads, allowing equipment manufacturers to scale output according to fan size and coverage area without redesigning the core atomization unit.
Key Technical Specifications and Models
SWT offers defined model references within this series, including:
- ATD16-2400GSW (16mm, 1700KHz)
- ATD20-170GSW (20mm, 1700KHz)
These models provide misting fan manufacturers with standardized specifications for disc diameter and operating frequency, supporting predictable integration into existing fan housings and drive electronics.
Driving Method and Circuit Design
Beyond the disc itself, SWT documents the supporting circuit architecture used in ultrasonic humidifier systems. The ultrasonic humidifier circuit consists of a power supply circuit, an oscillator circuit, and a water level control circuit. In operation, AC voltage is stepped down by a transformer and then passed through a bridge rectifier filter circuit to provide working voltage for both the water level control circuit and the oscillator. The oscillator simultaneously emits corresponding frequency signals that drive the atomizing disc. This level of circuit-level transparency gives engineering teams the technical basis needed to design compatible drive systems around the atomizing disc rather than treating it as a black-box component.
Manufacturing Excellence Behind SWT’s Atomizing Discs
Integrated Supply Chain and Production Scale
A defining differentiator for SWT is its integrated supply chain, with comprehensive control over the front, middle, and rear processes of piezoelectric ceramic production, including film squeezing, casting, and dry pressing. For atomizing disc manufacturing specifically, SWT applies tape casting (flow casting) for thin sheet formation and dry pressing for thick sheet formation, followed by complete processing steps covering squeezing, laminating, sintering, polarizing, and automated testing.
This vertical integration is supported by substantial manufacturing infrastructure: SWT maintains over 400 sets of instruments and equipment, including large-scale automatic tunnel furnaces and automated assembly machines, across its Dongguan headquarters (24,000 square meters) and Guizhou branch in Bijie City (4,000 square meters). The company reports that it maintains the largest production capacity in mainland China for specific piezoelectric components, with an annual output reaching approximately 250 million units.
Certifications and Quality Assurance
For buyers requiring regulatory alignment, SWT’s atomization series is documented as matching ISO13485, ISO14001, ISO9001, IATF16949, RoHS, REACH, MDR (EU 2017/745), and FDA requirements. The company additionally holds IATF 16949:2016 automotive quality management certification, ISO 9001:2015, and ISO 14001:2015, along with RoHS and REACH compliance across its product range. Internally, quality assurance is supported by an in-house reliability laboratory equipped for acoustic curve testing and environmental stress screening.
SWT’s intellectual property position includes 42 certified patents, of which 9 are invention patents and 30 are project-certified patents, registered under the SWT trademark. The company has also been recognized as a National High-Tech Enterprise and a Specialized and Innovative "Little Giant" Enterprise in Guangdong Province and Dongguan City, alongside a National Patent Award (Excellence Award) and a Dongguan Excellent Patent Award.
Industry Applications
Within SWT’s documented industry coverage, the Smart Home & Appliances segment includes feedback sounders for white goods and USB humidifiers, directly relevant to misting fan and humidification equipment manufacturers. The broader Ultrasonic Atomization Series also extends to Industrial & Maritime use cases such as ultrasonic cleaning and flow sensing, reflecting the versatility of SWT’s piezoelectric ceramic platform beyond consumer humidification.
Company Background and Credibility
SWT’s standing in the electroacoustic and piezoelectric component industry is further reinforced by its role as a primary drafter of Chinese industry standards for buzzers, ultrasonic atomizers, and piezoelectric sensors. The company was appointed in 2010 to draft local industry standards for piezoelectric and electromagnetic sounders in Guangdong Province, with official approval and publication of these standards following in 2012. SWT is the official drafter of the "Piezoelectric Sounders and Piezoelectric Buzzers" and "Electromagnetic Sounders and Electromagnetic Buzzers" standards.
Customer feedback cited in SWT’s documentation highlights "professional problem-solving," "excellent quality," and "strong service awareness" as recurring reasons behind long-term partnerships. On the service side, SWT offers one-on-one technical service solutions and customized product development (OEM/ODM), with a sample lead time of 3–7 days, bulk production lead time of 15–20 days, and 24-hour on-site response within the Pearl River Delta region.
Conclusion
For procurement teams and equipment designers evaluating an atomizing disc for misting fan applications, SWT’s Glass Glaze/Ultrasonic Atomization Sheets line offers documented technical specifications, multi-head scalability, transparent circuit design guidance, and a manufacturing base built on an integrated, high-volume supply chain. Combined with relevant certifications and a standards-drafting role within the piezoelectric and electroacoustic industry, these factors provide a verifiable basis for evaluating SWT’s atomizing disc products against project-specific humidification requirements.
