UL-04复合型过滤器产品介绍（中英对照）
中文版：
UL-04复合型过滤器是一款针对现代工业和民用场景开发的多功能过滤解决方案。该产品通过优化材料组合与结构设计，可有效拦截空气中的悬浮颗粒物及部分气态物质，适用于通风系统、设备防护和室内空气质量改善等场景。
核心设计采用三层渐变式过滤结构：首层预过滤网以高密度纤维材料为基础，可初步捕捉大直径粉尘和毛发；中间层复合静电驻极技术织物，通过纤维表面静电效应吸附微米级颗粒；末层活性炭基材通过蜂窝状结构设计，辅助吸附常见挥发性物质。三层次过滤体系兼顾物理拦截与吸附功能，形成渐进式净化效果。
本产品在材料选择上注重环境友好性，主体框架采用可回收改性塑料，过滤介质通过高温定型工艺处理，避免使用过程中纤维脱落。针对不同使用场景，提供定制化安装适配方案，兼容主流设备接口规格。建议定期检查滤材状态，在中等污染环境下常规使用寿命可达3-6个月。
UL-04过滤器在研发过程中特别关注用户体验，通过降低风阻设计减少设备能耗。模块化结构支持快速拆装维护，表面防潮处理可适应湿度波动环境。适用于办公场所、教育机构、轻型工业车间等需要持续空气净化的场景，建议配合专业设备进行周期性系统维护以获得最佳使用效果。
English Version:
The UL-04 Composite Filter is a multi-functional filtration solution developed for modern industrial and civil applications. Through optimized material combinations and structural design, this product effectively captures airborne particulate matter and certain gaseous substances, suitable for ventilation systems, equipment protection, and indoor air quality improvement scenarios.
The core design features a three-layer progressive filtration structure: The primary pre-filter layer utilizes high-density fiber material to capture large-diameter dust and hair particles. The intermediate layer integrates electrostatically charged fabric that adsorbs micron-level particles through surface electrostatic effects. The final activated carbon substrate employs a honeycomb structure design to assist in adsorbing common volatile compounds. This tri-level system combines physical interception and adsorption mechanisms to achieve progressive purification.
Environmentally conscious material selection is emphasized, with the main frame constructed from recyclable modified plastics. The filtration media undergoes high-temperature stabilization to prevent fiber shedding during operation. Customizable installation solutions are available to accommodate mainstream equipment interfaces. Under moderate pollution conditions, the recommended service life ranges from 3 to 6 months with regular inspection.
Developed with user experience in focus, the UL-04 filter incorporates airflow resistance reduction technology to minimize energy consumption. Its modular structure allows quick disassembly for maintenance, while moisture-resistant surface treatment ensures stable performance in humid environments. Ideal for office spaces, educational institutions, and light industrial workshops requiring continuous air purification. Periodic system maintenance with professional equipment is advised for optimal performance.
