Product Description:
The Festo D Series MINI-class pressure regulators, also known as the LR series, are direct-acting diaphragm pressure regulators. They are specifically engineered to maintain a consistent output pressure, regardless of any fluctuations in inlet pressure or variations in air consumption within the network.
The “-7” models in this series offer a pressure regulation range from 0.5 to 7 bar, making them particularly suitable for applications that require lower output pressures. These regulators come with threaded port sizes that vary from G1/8 up to G3/8, accommodating a range of installation preferences.
These devices provide nominal flow rates between 1,000 and 1,800 liters per minute and are designed to operate under pressures from 1 to 16 bar. Their sturdy die-cast zinc housings ensure durability and make them ideal for use in standard industrial settings.
Models marked with the “-MPA” suffix include an integrated pressure gauge, allowing for direct and convenient pressure monitoring. Conversely, versions without the “-MPA” suffix are supplied without a pressure gauge but still feature two ports intended for attaching pressure gauge accessories as needed.
Additionally, all Festo D Series MINI-class regulators come with a lockable rotary knob, which helps to prevent any unintentional changes to the pressure settings, enhancing safety and reliability in operation.
Features:
Pressure Regulation Range
The device is engineered to operate within a pressure regulation range of 0.5 to 7 bar. It is especially suitable for applications that demand lower output pressures, delivering highly precise control throughout this range.
Direct-Acting Diaphragm Design
Featuring a direct-acting diaphragm, the regulator boasts low hysteresis and outstanding regulation performance. This design guarantees stable and accurate control of the output pressure.
Primary Pressure Compensation with Secondary Venting
The built-in primary pressure compensation combined with a secondary exhaust channel ensures optimal regulation even at elevated flow rates. Additionally, an automatic return valve activates in the event of overpressure, enhancing the safety of the system.
Lockable Rotary Knob
Equipped with a rotary knob that includes a detent and integrated locking mechanism, the regulator prevents unintended pressure adjustments. This lockable feature is standard across all available models.
Two Pressure Gauge Ports
Two pressure gauge connections provide versatile mounting possibilities, including options for front panel installation via accessories or direct in-line setup.
Robust Metal Construction
The regulator's housing is made from die-cast zinc, featuring corrosion resistance classification CRC 2. This ensures a durable performance even in challenging industrial environments.
Flexible Installation Options
Designed for convenience, the regulator supports various installation methods such as front panel mounting (using accessories), in-line installation, or any orientation within an assembly.
Wide Operating Pressure Range
With an input pressure range from 1 to 16 bar, the device is compatible with a broad spectrum of compressed air systems.
High Flow Rate with Low Pressure Drop
- G1/8 models (LR-1/8-D-7-MINI / -MPA): Standard nominal flow rate of 1,000 l/min
- G1/4 models (LR-1/4-D-7-MINI / -MPA): Standard nominal flow rate of 1,600 l/min
- G3/8 models (LR-3/8-D-7-MINI / -MPA): Standard nominal flow rate of 1,800 l/min
High Precision Regulation
The regulator achieves a maximum pressure hysteresis of only 0.2 bar, ensuring exceptionally precise output pressure control.
Compatibility with Lubricated Operation
This device is compatible with lubricated compressed air systems. Once lubricated operation is initiated, it must be maintained continuously to ensure optimal performance.

Applications:
Pressure regulation and control plays a vital role in pneumatic systems that demand a lower output pressure range, typically between 0.5 and 7 bar. This is particularly important for sensitive pneumatic components and actuators which require precise handling to function optimally.
In automated production lines and assembly systems, maintaining precise and stable pressure control is critical. Such accuracy ensures consistent performance and reliability throughout the manufacturing process, minimizing errors and downtime.
Stabilising the air supply is essential for pneumatic tools and instruments, especially those operating within the 7 bar output range. Proper pressure management helps maintain the efficiency and longevity of these devices under continuous use.
In the field of mechanical engineering and industrial equipment, preparing compressed air and managing its pressure is a fundamental task. Effective pressure control supports the smooth operation of machinery and enhances overall productivity.
Laboratory, testing, and research and development environments often require pressure regulation with inert gases. This application demands high accuracy and safety, ensuring experimental conditions are consistently maintained.
Some systems also require a lockable pressure setting to prevent tampering or unauthorized adjustment. This feature is crucial in environments where maintaining specific pressure settings is necessary for safety and operational integrity.
Applications that rely on consistent and repeatable pressure, such as precision machining and automated inspection, benefit greatly from advanced pressure control technologies. These systems ensure high-quality output by reducing variability.
Additionally, oil-lubricated pneumatic systems that are compatible with lubricated operation require specialized pressure control solutions to match their unique maintenance and performance needs.
Support and Services:
Our Pneumatic Filter Regulator Lubricator (FRL) units are designed to ensure optimal performance and longevity of your pneumatic systems by providing clean, regulated, and lubricated air supply. For technical support, please ensure that your FRL unit is installed according to the manufacturer’s guidelines, including proper orientation and secure connections.
Regular maintenance is crucial for the efficient operation of the FRL. Replace filter elements periodically to prevent contamination, check the regulator settings to maintain the desired pressure, and refill the lubricator with the recommended oil type to ensure adequate lubrication of downstream components.
If you encounter any issues such as pressure fluctuations, air leaks, or insufficient lubrication, start by inspecting the unit for any visible damage or blockages. Clean or replace the filter element if clogged, verify that the regulator knob is properly adjusted, and ensure the lubricator reservoir contains oil and is free from airlocks.
For detailed troubleshooting, calibration procedures, and maintenance schedules, refer to the product manual provided with your FRL unit. Our technical support team is also available to assist with complex issues or replacement parts identification to minimize downtime and maintain system reliability.
We recommend using only genuine replacement parts and accessories to preserve the integrity of your pneumatic system and to comply with warranty terms. Proper installation, routine inspection, and timely servicing will help you achieve the best performance from your Pneumatic Filter Regulator Lubricator.
