AW Series Filter Regulator

AW Series Filter Regulator | SOLIH Integrated Compressed Air Filtration & Pressure Reducing Unit

Brand: SOLH by Richge Technology | All‑in‑one Pneumatic Air Source Treatment Unit

1. Product Overview

     SOLIH AW series filter‑regulator is an all‑in‑one air source treatment unit integrating air filtration and pressure regulation functions. It performs primary air purification and pressure stabilization right after air compressors, serving as a space‑saving alternative to separate AF filter plus AR regulator assemblies. Compact construction simplifies field installation and reduces overall pneumatic system footprint.

2. General Technical Specifications

3. Model & Port Size Range

  Model Code Explanation & Examples

     • AW2000‑02: Filter‑regulator, series 2000, Rc1/4", manual drain

     • AW4000‑04D: Filter‑regulator, series 4000, Rc1/2", automatic drain

     • AW3000‑03G: Filter‑regulator fitted with pressure gauge

4. Structural Features & Advantages

     • Integrated One‑piece Design: Filter bowl and pressure regulator are combined into one unit for simpler installation and fewer connection points.

     • Cyclone Water Separation: Centrifugal swirling removes liquid water before air passes through filter cartridge, effectively extending filter element service life.

     • Pull‑to‑adjust & Push‑to‑lock Knob: Pull up knob to adjust pressure; push down to lock position, preventing unintended pressure change caused by vibration or accidental touch.

     • Built‑in Pressure Gauge Port: Direct mounting port for pressure gauge without extra adapters.

     • Transparent PC Bowl with Protective Cover: Real‑time visual observation of water level inside filter bowl.

     • Modular Splicing Compatibility: Can be directly assembled with AL series lubricator to build complete AC‑series FRL three‑unit combo.

5. Typical Application Scenarios

     • Primary air purification and pressure stabilization for automation equipment, machine tools and production lines

     • Front‑end air source treatment for spraying equipment, pneumatic tools, solenoid valves and cylinders

     • Centralized pressure regulation & purification for workshop main pipelines and air compressor outlets

6. Maintenance Guidelines

     • Drain condensate regularly; keep water level below warning line.

     • Replace filter element when pressure drop rises obviously or after 6‑12 months of normal operation.

     • Mount vertically; align body airflow arrow with actual air flow direction.

7. Recommended Air Circuit Combinations

     • Standard lubricated circuit: AW filter‑regulator → AL lubricator → pneumatic actuator

     • Oil‑free clean circuit: AW filter‑regulator (without AL lubricator) → pneumatic actuator
