Classic Compressed-Air Preparation

Festo Classic Compressed-Air Preparation

The Festo Classic compressed-air preparation range delivers essential pneumatic air treatment in an industrial automation context. These units are designed to filter out contaminants, regulate pressure reliably and, if required, provide lubrication to downstream pneumatic components — all within a compact, proven package.

These units incorporate standard combinations of filters, pressure regulators, lubricators and associated accessories, enabling machine builders and system integrators to deploy a prepared air supply quickly and cost-effectively. The Classic series supports robust performance with durable materials and easy servicing, making them well suited for general automation, packaging, handling, and machine tool systems.

⭐ Important: The Classic series offers fundamental compressed-air quality control — filtration, regulation and lubrication — with reliable service life and ease of maintenance, making them the go-to choice for standard pneumatic infrastructure.

Design & Functionality

Compressed-air preparation units in the Classic series operate by first removing particulate matter, condensate and oil carry-over through filters; then by regulating the outlet pressure via a reliable pressure regulator; and optionally providing a lubricator to add oil mist for maintaining downstream pneumatic component life. The modular design enables customization for specific applications: for example, adding branching modules, exhaust valves or pressure indication.

Available variants include:
• Filter-regulator units (FRL)
• Filter / regulator only modules
• Lubricator modules for oil-mist lubrication
• Branching or exhaust modules for complex pneumatic networks

These units are built for low maintenance, fast servicing (for example by simply replacing filter elements or drain cartridges) and are compatible with the broader Festo service-unit ecosystem.

⭐ Important: Modular design and ease of servicing ensure minimal downtime and efficient integration into existing pneumatic systems.

Total Crossed Beams

(Applied to the functional coverage of preparation families)

This series ensures full coverage of standard compressed-air treatment functions across typical pneumatic installations — from basic filtration and pressure regulation to lubrication and branching for sub-networks. It supports a wide range of port sizes, flow capacities and accessory modules to match standard industrial demands.

Regardless of installation orientation or machine layout, the Classic series delivers consistent air quality, stable pressure delivery and reduced contamination risk — thereby supporting higher machine availability and longer component life.

Beam Pitch Options

(Translated as: configuration variants, mounting options, flow capacities)

The Classic series offers a variety of configuration options including:
• Multiple port sizes to suit different flow requirements and machine sizes
• Filter/regulator only or full FRL combinations
• Manual and automatic condensate drain options
• Lubricator module option for adding oil mist to the air stream
• Standardised mounting (bracket or modular manifold) for ease of integration
• Option for pressure gauge or digital pressure indication

This gives users the flexibility to choose the right preparation level — whether it’s a compact unit for a small station or a higher-flow model for a larger pneumatic line.

⭐ Important: The wide range of variants ensures optimal matching of air preparation to the machine’s footprint, flow demand and maintenance context.

Intrinsic Synchronism

The internal design of the Classic units ensures synchronized operation of filtration, regulation and lubrication components — maintaining consistent outlet pressure, minimal pressure drop and reliable flow under varying load conditions. Standardised porting and mounting interfaces allow these units to align seamlessly with other Festo pneumatic system components, enabling simplified spares management and easier system upgrades.
