Feature: Medium is compressed air. Business Impact: Ensures clean, dry actuation common to pneumatic systems while simplifying supply chain considerations. Application: Best suited for general machinery and automation panels that rely on stable air pressure. Feature: Maximum Inlet Pressure of 20 bar. Business Impact: Allows operation from standard plant air networks with ample safety margin, reducing the need for separate high-pressure regulators. Application: Automated lines and CNC tooling where surges are possible. Feature: Outlet Pressure Adjustment from 0.3 to 4 bar (0.3–4 bar, 4–58 psi). Business Impact: Delivers precise control over downstream actuators, improving cycle timing and repeatability. Application: Pneumatic cylinders and gripping tools in assembly cells.Feature: Relieving design. Business Impact: Relieves excess pressure when venting, protecting components and enabling faster recovery after setpoint changes. Application: High-dynamic pick-and-place or machining centers where rapid pressure changes occur.Feature: Port Size 3/8" PTF and Gauge Port 1/8" PTF with flush-mounted integrated gauge. Business Impact: Reduces assembly footprint and simplifies monitoring, leading to shorter setup times and easier diagnostics. Application: Panel-mounted regulators in compact automation enclosures.Feature: Weight of 0.79 kg and compact dimensions (186 mm height, 70 mm length, 74 mm width). Business Impact: Easier handling and installation in tight booths, with less parasitic load on mounting structures. Application: Retrofit projects and new builds with space restrictions. Feature: Materials - Diecast aluminium body, POM bonnet, nitrile elastomers. Business Impact: Combines durability with resistance to typical industrial oils and seals, improving lifecycle performance. Application: Harsh production environments where reliability matters. Feature: 125 dm3/sec (265 scfm) flow. Business Impact: Sufficient capacity to feed multiple actuators without pressure drop, reducing the risk of under-pressurized tooling. Application: General purpose air distribution to automation cells. Feature: T-bar adjustment. Business Impact: Simple, repeatable setpoint changes without tools, lowering maintenance time. Application: Routine calibration in changing production mixes. Feature: Integrated gauge for flush mounting. Business Impact: Immediate visibility of downstream pressure without additional instruments, improving diagnostics. Application: Panel installations where visibility and space are at a premium.

FAQs
Begin by selecting a suitable mounting location on a clean, dry panel. Connect the 3/8" PTF inlet and the 1/8" gauge port using appropriate fittings, ensuring all connections are leak-free. Mount the regulator with the gauge facing for easy visibility, then set the outlet pressure with the T-bar, and verify operation with a low-pressure test. Use the Excelon Plus mounting accessories if panel space is limited. This approach minimizes installation time and reduces the risk of misalignment or leaks during commissioning.
Key specs include a maximum inlet pressure of 20 bar, adjustable outlet pressure from 0.3 to 4 bar (4 to 58 psi), and a flow capacity of 125 dm3/sec (265 scfm). The regulator is designed for compressed air and operates within -20 to 65 °C. The body is diecast aluminium with a POM bonnet and nitrile elastomer seals, providing robust durability in typical industrial environments.
Yes, the R84G-3AT-RFG provides a precise 0.3–4 bar output range with a flush-mounted integrated gauge for real-time monitoring, plus a T-bar adjustment for repeatable setpoints. Its compact form factor and reliable flow of 125 dm3/sec help maintain consistent actuator performance, reducing cycle time variability and improving overall line efficiency in automation cells.
Region-specific certifications should be verified with the supplier. In general, regulators like the Excelon Plus series are aligned with CE compliance for Europe and are designed to support safe operation in environments requiring IP-rated enclosures and compatibility with SIL-rated control logic where applicable. Always confirm applicable certifications and test certificates for your specific installation and regulatory regime.
For elastomer durability and ongoing reliability, use the Excelon Plus R84/B84 Elastomer Service Kit (FRLB84-KIT) when performing routine seals replacement. Additional mounting and gauge accessories—such as Excelon Plus Quikclamp kits and integrated gauge packages—help maintain performance and simplify retrofits. Regular inspection of the gauge accuracy and port leaks will sustain optimal regulation and reduce downtime.
