AC Series FRL Three-Unit Combo

AC Series FRL Three-Unit Combo | AF+AR+AL Pneumatic Air Source Treatment Triple Assembly

Brand: SOLIH by Richge Technology | Standard Industrial FRL Pneumatic Service Unit

1. Product Overview & Definition

     The SOLIH AC series FRL three-unit combo is a standard full-set pneumatic air source treatment assembly, consisting of an AF air filter + AR pressure regulator + AL air lubricator. It completes the whole-process pneumatic air treatment: impurity & moisture filtration, stable pressure regulation and precise micro-oil lubrication in one modular unit. It provides comprehensive protection for downstream pneumatic components such as cylinders, solenoid valves and pneumatic motors, effectively reducing component wear, avoiding jamming failure and extending the service life of the entire pneumatic system. It is the most standard and essential core assembly for traditional lubricated pneumatic circuits.

3. Core Technical Parameters

4. Structural Features & Product Advantages

     • Integrated Modular Structure: Standard spliced modular design realizes quick installation, disassembly and replacement. Each unit can be maintained independently, greatly reducing on-site maintenance difficulty and replacement cost.

     • High-Efficiency Cyclone Water Separation: The filter adopts centrifugal swirl water removal structure, which quickly separates liquid water and large particles in the air, protecting the precision filter element and improving overall air purification efficiency.

     • Overflow Type Stable Pressure Regulation: The pressure regulator adopts overflow voltage stabilizing structure with fast response and stable pressure output, effectively avoiding pressure drift and fluctuation caused by flow change or equipment vibration.

     • Knob Self-Locking Adjustment: Self-locking pressure regulating knob design prevents pressure parameter change caused by accidental touch or long-term vibration, ensuring long-term stable operation of pneumatic system.

     • Visual Oil & Water Level Design: Transparent PC cup with safety protective cover enables real-time observation of filter water level and lubricator oil level, facilitating timely drainage and oil replenishment.

     • Independent Replaceable Consumables: Filter element and lubricator core can be replaced separately without replacing the whole set of units, lowering long-term operating cost.

5. Standard Air Circuit Working Flow

  Air Compressor → AC FRL Three-Unit → Solenoid Valve → Pneumatic Cylinder / Pneumatic Actuator

     The three-unit performs step-by-step air treatment: filtering moisture and impurities → stabilizing input pressure → atomizing lubricating oil, providing clean, stable and lubricated air source for terminal pneumatic components.

6. Typical Application Scenarios

     • Industrial Automation Equipment: Air source pretreatment for automatic machine tools, manipulators and automated production lines.

     • Light Industry Manufacturing Lines: Stable air supply for packaging, printing, textile and electronic processing equipment.

     • Lubricated Pneumatic Components: Special air source treatment for telescopic cylinders, pneumatic grippers and pneumatic motors that require oil lubrication.

     • Workshop Centralized Air Source System: Secondary purification and pressure stabilization for air compressor main pipeline to improve overall pneumatic system stability.

7. Selection Guide: Two-Unit VS Three-Unit

8. Daily Maintenance Instructions

     • Drain water regularly to ensure the water level in the filter cup is below the warning line.

     • Replace the filter element in time when the air pressure difference increases obviously or after 6–12 months of conventional use.

     • Install vertically strictly according to the airflow arrow on the valve body to ensure normal treatment efficiency.

     • Check the oil mist atomization status regularly to ensure uniform lubrication of terminal components.

One Sentence Summary

     The SOLIH AC series FRL three-unit combo integrates filtration, pressure stabilization and micro-lubrication functions, featuring modular installation, stable pressure output and visual oil-water monitoring, being the standard and most widely used air source treatment solution for conventional lubricated pneumatic automation systems.
