By the end, you will have a clear picture of whether the Chanto UAR20-2G pressure regulator is a good match for your plant or machine—and how to get the most value from it.
Understanding the Chanto UAR20-2G Pressure Regulator in Your Air Prep Line
To appreciate what the Chanto UAR20-2G pressure regulator brings to your system, it helps to start with the basics of air preparation. Compressed air leaves the compressor at a higher pressure than most tools and actuators actually need. Without regulation, that excessive pressure can cause seals to wear out faster, valves to fail prematurely, and cylinders to slam at the end of stroke. The Chanto UAR20-2G pressure regulator sits between your supply and your downstream devices, reducing and stabilising that pressure to a safe and optimal level.
The Chanto UAR20-2G pressure regulator is part of Chanto’s UAR series and matches the compact UAC20 FRL combination size. It is designed for clean, dry compressed air, with a working outlet range of 0.05–0.85 MPa and a maximum operating pressure of 1.0 MPa. This means the Chanto UAR20-2G pressure regulator is perfectly suited to standard plant air systems that typically run around 0.6–0.7 MPa (6–7 bar), giving you enough adjustment room for low-pressure circuits while still offering a comfortable margin below its maximum rating.
Another advantage of the Chanto UAR20-2G pressure regulator is the integrated round pressure gauge—the “2G” portion of the model code indicates the configuration with a round gauge. Having a local gauge on the body makes it easy for technicians and operators to verify set pressure at a glance, without needing an external pressure switch or separate indicator.
Key Specifications of the Chanto UAR20-2G Pressure Regulator
When selecting any regulator, understanding the technical details is crucial. The Chanto UAR20-2G pressure regulator offers a blend of compact size and robust ratings that makes it attractive for panel builders, OEMs, and maintenance teams.
At its core, the Chanto UAR20-2G pressure regulator is rated for a working pressure range of 0.05–0.85 MPa, with a maximum operating pressure of 1.0 MPa and a proof pressure of 1.5 MPa. This means the Chanto UAR20-2G pressure regulator can safely handle typical industrial air pressures while maintaining a safety margin during occasional over-pressurisation events.
The main port size of the Chanto UAR20-2G pressure regulator is configurable for 1/8" and 1/4" connections, depending on how you order it. This makes it suitable for both small pilot lines and slightly larger branch circuits. The gauge port itself is 1/8", which is standard in many pneumatic regulators and allows for easy replacement or upgrading of the gauge if needed.
From a temperature perspective, the Chanto UAR20-2G pressure regulator is typically specified for –5 °C to +60 °C in non-freezing conditions, matching the broader UAR/UAC series. This range covers most indoor factory environments and many sheltered outdoor installations. Combined with the regulator’s aluminium alloy body and oil-resistant elastomer seals, the Chanto UAR20-2G pressure regulator delivers the durability that industrial users expect.
How the Chanto UAR20-2G Pressure Regulator Fits into FRL Systems
Modern pneumatic systems rarely use a regulator in isolation. Instead, air is prepared using a combination of filtration, regulation, and lubrication—often referred to as a Filter Regulator Lubricator (FRL) unit. In this arrangement, the filter removes particulates and moisture, the regulator stabilises pressure, and the lubricator introduces a controlled oil mist when required by downstream components. The Chanto UAR20-2G pressure regulator is the regulator component for Chanto’s compact UAC20 FRL assemblies.
In a typical setup, you might see a UAF20 filter mounted upstream of the Chanto UAR20-2G pressure regulator. The filter removes particles and some moisture from the compressed air, which helps protect the internal seals and seat of the Chanto UAR20-2G pressure regulator itself. Downstream, a UAL20 lubricator can be added to deliver controlled oil mist to cylinders and valves if your application requires lubrication.
The beauty of the Chanto UAR20-2G pressure regulator is that it has been designed to mechanically and pneumatically integrate with these FRL partners. Chanto offers brackets, joiner kits, and modular connectors that allow you to assemble a UAF20 + Chanto UAR20-2G pressure regulator + UAL20 stack with neat, matched port sizes and a consistent appearance. This modular approach simplifies panel design and makes it easy to expand or reconfigure as your machine evolves.
For users who need finer filtration, a UAFM20 mist separator can be inserted before the Chanto UAR20-2G pressure regulator. This helps remove residual oil mist from the air, which can be essential in food and beverage, electronics, or other sensitive applications where oil-free air is critical.
Internal Construction and Build Quality of the Chanto UAR20-2G Pressure Regulator
Although you may never see the inside of your regulator, its internal construction is what determines how reliable it will be over time. The Chanto UAR20-2G pressure regulator uses an aluminium alloy body, which delivers a good balance of strength, corrosion resistance, and low weight. Inside, the Chanto UAR20-2G pressure regulator uses oil-resistant NBR (nitrile) or similar elastomer seals, which are standard for industrial pneumatics and compatible with typical compressed air environments.
This combination of materials makes the Chanto UAR20-2G pressure regulator suitable for general manufacturing, packaging, and automation lines. The body is designed to withstand the product’s 1.5 MPa proof pressure, while the seals and internal components support stable control across the 0.05–0.85 MPa working range. In practical terms, this means the Chanto UAR20-2G pressure regulator can maintain downstream pressure without hunting or drifting excessively when installed and sized correctly.
Additionally, the integrated round gauge on the Chanto UAR20-2G pressure regulator usually features a dual-scale dial (bar and psi), making it easier for teams working with different units to interpret the reading. For applications requiring electronic monitoring, Chanto also offers optional digital pressure switches within the same regulator family, although those configurations have different model codes from the UAR20-2G.

Installing the Chanto UAR20-2G pressure regulator in the proper orientation ensures accurate pressure control and a readable gauge.
Next, use appropriate fittings for the 1/8" or 1/4" ports on the Chanto UAR20-2G pressure regulator. Match the thread type—often Rc, NPT, or G—based on how your specific unit was ordered. Apply PTFE tape or a suitable thread sealant sparingly, making sure no loose tape fragments can enter the pilot passages of the Chanto UAR20-2G pressure regulator and cause blockages.
For mounting, Chanto offers L-type and T-type brackets that make it simple to secure the Chanto UAR20-2G pressure regulator to a wall, panel, or machine frame. Typically, you would fasten the bracket first, then attach the regulator body using the screws provided. Ensure there is enough clearance above the knob so that users can pull up to unlock, twist to adjust, and push down to lock the Chanto UAR20-2G pressure regulator without interference.
When commissioning, bring the system up to pressure slowly. With the Chanto UAR20-2G pressure regulator installed, pull up the knob to unlock, gradually adjust the knob while watching the gauge until you reach your desired downstream pressure, and then push the knob down to lock. Periodically inspect for leaks around fittings and verify that the pressure setpoint remains stable during operation.
