494.35型（G3/8″接口）过滤器产品介绍
中文版：
494.35型过滤器是一款专为中小型流体系统设计的精密过滤装置，采用G3/8″标准螺纹接口，适用于各类液体介质的杂质过滤需求。产品采用分层式过滤结构设计，内置多层复合滤芯，能有效拦截粒径大于80微米的固体颗粒物，帮助维持管路系统的洁净运行环境。
本产品壳体选用高强度黄铜配合工程树脂复合材质，在保证结构强度的同时兼顾轻量化需求。模块化快装设计可实现无需专业工具的单人操作，旋接式安装方式大幅缩短设备维护时间。特殊设计的防渗漏密封环能适应-20℃至120℃的工作温度区间，在0.6-1.2MPa压力范围内保持稳定工作性能。
该型号过滤器主要应用于小型水处理设备、仪器仪表配套管路、实验室流体控制系统等场景。其紧凑型外观设计（整体长度不超过120mm）特别适合空间受限的安装环境，顶部可视化观察窗可实时监测滤芯状态。经实验室模拟测试，在常规水质条件下建议每800工作小时或压差超过0.15MPa时进行滤芯维护。
产品优势体现在三个维度：流体兼容性方面支持清水、冷却液、润滑油等常见介质；维护便利性方面提供可拆卸清洗式滤芯组件；经济性方面采用长寿命设计延长部件更换周期。建议搭配前置粗滤设备使用以获得更佳的系统保护效果。
English Version：
The Model 494.35 filter with G3/8" threaded connection is engineered for precision filtration in compact fluid systems. Featuring a multi-stage filtration mechanism, this unit effectively captures particulate matter exceeding 80 microns in diameter, ensuring cleaner fluid transmission in various industrial applications.
Constructed with brass-reinforced polymer housing, the filter achieves optimal balance between structural integrity and weight reduction. Its tool-free installation design allows quick assembly/disassembly within minutes, while the temperature-resistant sealing components maintain reliable performance across -20℃ to 120℃ operating conditions. The pressure tolerance range of 0.6-1.2MPa makes it suitable for most standard industrial environments.
Ideal for compact installations with spatial constraints, this 120mm-long filtration solution finds typical applications in laboratory instrumentation, small-scale water treatment units, and auxiliary hydraulic circuits. The transparent inspection window on the upper housing enables visual monitoring of filter element status without disassembly. Maintenance intervals are recommended at every 800 operational hours or when pressure differential exceeds 0.15MPa under normal water-based service conditions.
Key advantages include broad fluid compatibility (water, coolants, light oils), service-friendly cartridge design for easy cleaning/reuse, and extended service life through wear-resistant material selection. For enhanced system protection, pairing with a primary coarse filter is advised to optimize filtration efficiency and component longevity.
