6. Structural Features & Product Advantages

     • Integrated Modular Design: Integrated filter and regulator structure realizes one-piece installation and disassembly, greatly saving pipeline space and simplifying on-site layout and daily maintenance.

     • Efficient Water Separation & Long Service Life: Front-stage centrifugal swirl separation removes large water mist and impurities efficiently, reducing filter element load and extending the service life of the 5μm precision filter element.

     • Stable Pressure Output & Fast Response: Overflow type pressure regulating structure ensures sensitive pressure response and stable downstream pressure, effectively avoiding pressure fluctuation during equipment operation.

     • Anti-Misoperation Self-Locking Structure: Knob self-locking pressure regulation design prevents pressure drift caused by equipment vibration or accidental touch, ensuring long-term stable pneumatic system parameters.

     • Visual Water Level Monitoring: Transparent PC water cup with protective cover realizes real-time visual observation of water level, avoiding excessive water accumulation affecting filtration quality and downstream components.

     • Free Upgrade & Expansion: Standard modular interface supports direct splicing with AL oil mister, quickly upgrading to a complete three-unit FRL assembly for lubricated pneumatic circuits.

7. Typical Application Scenarios

     • Automation Industrial Equipment: Air source pretreatment for automated machines, machine tools, robotic arms and precision automation production lines.

     • Light Industry Pipeline Equipment: Stable purification for electronics, packaging, printing, textile and assembly line pneumatic systems.

     • Pneumatic Component Protection: Front-end filtration and pressure stabilization for cylinders, solenoid valves and pneumatic tools to reduce wear and failure rate.

     • Centralized Air Source Processing: Primary air purification and pressure regulation for factory workshop main air pipelines to improve overall air source quality.

8. Daily Maintenance Guidelines

     • Regular Drainage: Drain accumulated water in the cup regularly to ensure the water level is below the warning line and prevent liquid water from entering the downstream circuit.

     • Timely Filter Element Replacement: Replace the filter element immediately if differential pressure rises significantly; regular replacement every 6–12 months to maintain optimal filtration performance.

     • Standard Installation: Install vertically strictly following the airflow arrow on the body to ensure normal water separation and pressure regulation efficiency.

9. FRL Two-Unit & Three-Unit Selection Instructions

     • AC Two-Unit (Filter + Regulator): Suitable for oil-free and clean pneumatic equipment, such as electronic precision equipment, vacuum systems and oil-free cylinders.

     • AC Three-Unit (Filter + Regulator + Lubricator): Suitable for conventional pneumatic cylinders, pneumatic motors and moving pneumatic components that require oil lubrication.

One Sentence Summary

     The SOLIH AC series two-unit combo integrates high-efficiency air filtration and precise pressure stabilization, featuring modular installation, anti-drift pressure regulation and visual water level monitoring, being the most cost-effective and widely applicable standard air source treatment solution for industrial automated pneumatic systems.
