AD402系列过滤器产品介绍（中英对照）
中文版本：
AD402系列过滤器是一款专为精密流体控制系统设计的高效分离装置，适用于多种工业场景的介质提纯与杂质拦截需求。本产品采用模块化结构设计，主体由耐蚀合金与高分子复合材料构成，在保证机械强度的同时兼顾了化学稳定性。
产品主体采用多层复合过滤结构，通过物理拦截与深度吸附的双重作用机制，可有效分离液体或气体介质中粒径大于5微米的悬浮颗粒。内部流道经过流体力学优化，在实现高过滤效率的同时将压降损耗控制在合理范围，有助于降低系统能耗。过滤元件采用可拆卸式设计，用户可根据实际工况灵活更换不同精度的滤芯组件。
本装置适用于化工生产、工业水处理、食品加工等领域的介质净化环节。主体结构采用快装法兰连接方式，可无缝接入DN15至DN50管路系统。设备表面经过特殊防污处理，减少因介质残留造成的二次污染风险。操作界面配备可视化压力指示装置，便于实时监控过滤状态。
使用注意事项：建议定期检查密封件完整性，避免在超出额定温度（-20℃至120℃）范围的工况下连续运行。当压差指示器显示数值超过初始值30%时，应及时进行滤芯维护或更换操作。安装时应确保设备处于通风干燥环境，避免剧烈震动或外力冲击。
English Version:
The AD402 Series Filter is a high-efficiency separation device specifically designed for precision fluid control systems, suitable for media purification and impurity interception requirements in various industrial scenarios. Featuring a modular structure design, the main body is constructed from corrosion-resistant alloys and polymer composite materials, ensuring both mechanical strength and chemical stability.
The product adopts a multi-layer composite filtration structure that combines physical interception and deep adsorption mechanisms, effectively separating suspended particles larger than 5 microns in liquid or gas media. The optimized internal flow channels maintain high filtration efficiency while keeping pressure drop losses within reasonable limits, contributing to reduced system energy consumption. The filter element employs a detachable design, allowing users to flexibly replace cartridges with different precision levels according to actual working conditions.
This unit is suitable for media purification processes in chemical production, industrial water treatment, and food processing applications. The main structure utilizes quick-connect flange joints for seamless integration into DN15 to DN50 pipeline systems. The surface receives special anti-contamination treatment to minimize secondary pollution risks caused by media residue. The operational interface includes a visual pressure indicator for real-time filtration status monitoring.
Usage Notes: Regular inspection of seal integrity is recommended. Continuous operation should be avoided when exceeding the rated temperature range (-20℃ to 120℃). Filter maintenance or cartridge replacement should be performed promptly when the differential pressure indicator shows values exceeding 30% of the initial reading. Installation should ensure the equipment is placed in a ventilated, dry environment, protected from severe vibration or mechanical impact.
