AR40-04E-B: Precision Regulation, Stable Support! Filter Regulator with Gauge Empowers Reliable Pneumatic Systems

In pneumatic systems, stable and clean air pressure is fundamental for the reliable operation of actuators and consistent process quality. The AR40-04E-B is an integrated F.R.L. unit combining filtration, regulation, and a pressure gauge. With its core advantages of precise pressure regulation, efficient filtration, and visual indication, it provides pneumatic equipment with a constant, clean, and controllable power source, effectively protecting devices and enhancing system reliability.Core Product Advantages

• Three-in-One Efficient Integration
  • Precise Regulation (R):​ Utilizes a diaphragm balance structure for stable output pressure. Maintains constant outlet pressure despite inlet fluctuations, ensuring consistent actuator operation.
  • Efficient Filtration (F):​ Built-in filter element (e.g., 5μm) effectively removes water, oil mist, and solid particles from compressed air, protecting downstream components.
  • Pressure Indication (B):​ Integrated clear pressure gauge provides real-time, accurate output pressure reading for easy monitoring and adjustment.
• Automatic Drainage Function
  • The filter section is equipped with an automatic drain (E may indicate this feature), which expels accumulated liquids automatically, preventing maintenance oversights and ensuring continuous, efficient filtration.
• Safety Overflow Protection
  • If outlet pressure abnormally increases (e.g., due to thermal expansion), the regulator can automatically relieve excess pressure (overflow function), safeguarding downstream equipment.
• High Flow, Low Pressure Drop
  • Optimized internal flow paths minimize pressure loss and offer high flow capacity (Cv value), ensuring adequate air supply and fast system response.
• Compact and Durable Design
  • Compact structure saves space. Main body is aluminum alloy for corrosion resistance; NBR seals ensure long service life.

Typical Application Scenarios

• Pneumatic Equipment Inlet:​ Provides stable, clean operating pressure for cylinders, solenoid valves, pneumatic tools, etc.
