ALR Series Air Pressure Regulator - Precision Air Pressure Regulator
Product Advantages
The ALR series pressure reducing valves are professional solutions for air supply treatment, designed to enhance the performance of pneumatic systems. Their sensitive diaphragm structure precisely regulates pressure, effectively suppressing upstream fluctuations and flow changes, ensuring stable outlet pressure and reliable operation. Optimized internal flow channels achieve high flow rate and low pressure loss, meeting instantaneous high-flow-rate air supply demands and maximizing equipment performance.
For safety, the product is equipped with a high-performance relief valve that quickly vents air in case of abnormal pressure, effectively protecting downstream precision components. An integrated precision filter efficiently separates moisture, oil mist, and dust, supporting automatic/manual drainage to ensure clean air supply. The modular design allows for flexible combinations of filters, regulators, and lubricators, and features a locking handwheel and clear pressure gauge for easy adjustment and to prevent misoperation.
With stable air supply, efficient filtration, and flexible configuration, the ALR series is a reliable pressure regulating option for pneumatic systems.

FAQ
-
Q: In what situations should I choose a model with an oil mist lubricator (triple unit)?
A: You should choose a triple unit with an oil mist lubricator when your pneumatic system has components that require lubrication. For example, traditional cylinders, pneumatic valves, and some pneumatic tools require lubrication via an oil mist lubricator to reduce wear and extend their lifespan. If your system uses rodless cylinders or lubrication-free components, you can choose a two-unit unit that only includes a filter and regulator.
