Filter, Regulator & Lubricator (FRL) Combos A single, modular unit that combines three essential air preparation functions: filtration to remove particulates and moisture, regulation to deliver stable downstream pressure, and lubrication to protect pneumatic components. Designed to simplify installation, reduce footprint, and improve the reliability of compressed air systems. Key benefits Protects equipment: removes contaminants and adds controlled lubrication to extend the life of valves, cylinders, and air tools. Stabilizes performance: the regulator maintains consistent working pressure for repeatable, accurate pneumatic operation. Reduces downtime: combined maintenance points and easier access cut service time compared with separate components. Space- and cost-efficient: one integrated assembly replaces separate filter, regulator and lubricator units for simpler piping and mounting. What it does and how it solves problems Filtration: traps particulates and separates condensate to prevent nozzle clogs, valve sticking, and wear in pneumatic components. Regulation: lets you set and hold the required working pressure, avoiding overpressurizing tools or inconsistent actuation. Lubrication: introduces a controlled oil mist to bearings, seals and moving parts to reduce friction and friction-related failures. Important attributes Function: three-in-one air preparation — filter, regulator, lubricator — in a coordinated assembly compatible with general compressed-air installations. Compatibility: fits standard pneumatic systems and downstream pneumatic tools, valves, cylinders and actuators; works with common compressed-air lines and fittings. Size and mounting: compact, space-saving design that simplifies panel or rail mounting and minimizes piping runs. Material and construction: built for industrial use with durable housings and serviceable bowls/elements to support routine inspection and maintenance. Performance and reliability: designed to improve air quality and pressure stability, reduce contamination-related failures, and deliver repeatable tool performance. Service and maintenance Single-point maintenance reduces service time: many FRL combos allow easy access to filter elements, drain points and lubricator reservoirs. Visual inspection: clear or accessible bowls and straightforward level adjustment aid fast condition checks. Replaceable consumables: filter elements and lubricator fluid are replaceable to maintain ongoing performance. Typical applications Manufacturing and assembly: protects and prolongs life of pneumatic tools, grippers, and actuators on production lines where consistent pressure and clean air are required. Packaging and material handling: stabilizes pressure for repeatable pick-and-place cycles and lubricates moving mechanisms to prevent jamming and wear. General plant compressed-air systems: centralized or point-of-use air treatment for shops, test benches, and machine tools to reduce maintenance and improve uptime. Why choose an FRL combo Consolidates essential air preparation functions into a single, easy-to-install solution that improves upstream air quality and downstream equipment life. Reduces installation complexity and ongoing maintenance compared with separate components while delivering the core functions needed for reliable pneumatic operation. Specifications and selection tips Choose an FRL combo sized to match your system flow requirements and port sizes. Confirm material and bowl options appropriate for your environment (e.g., resistant housings or metal bowls for harsh conditions). Verify regulator control range and lubricator adjustability to ensure compatibility with your equipment’s pressure and lubrication needs. Notes Follow manufacturer installation and maintenance instructions for correct mounting, piping, pressure settings and servicing intervals. Use appropriate lubricants and filter elements recommended for your application to achieve the expected protection and performance.
