(Also known as Air Preparation Units / Filter–Regulator–Lubricator Assemblies with Automatic Drain)

FRL Units and Auto Drain are essential air preparation components designed to improve the performance, reliability, and lifespan of pneumatic systems in industrial manufacturing, automotive service, construction, and general maintenance environments. FRL stands for Filter Regulator Lubricator, which works together to clean, regulate, and condition compressed air before it reaches downstream tools and equipment. The filter removes dust, moisture, and contaminants; the regulator ensures a stable outlet pressure; and the lubricator provides a controlled oil mist to reduce internal wear and extend tool life.

An auto drain automatically removes accumulated water and impurities from the air filter bowl, preventing corrosion, blocked passages, and performance loss without requiring manual draining. Built with durable housings, precision valves, and long-life seals, these components deliver consistent airflow, improved efficiency, and dependable operation in continuous-duty applications. Their compact modular design allows easy installation, adjustment, and maintenance while supporting a wide range of pneumatic tools and machinery.

FRL Units and Auto Drain are ideal for factories, workshops, automotive garages, assembly lines, and industrial facilities that require clean, regulated, and properly lubricated compressed air to protect equipment, reduce downtime, enhance safety, and achieve reliable, high-performance pneumatic operation.
