WHAT IS AN FRL

An FRL unit (Filter – Regulator – Lubricator) is an integrated system for compressed air preparation. Three essential functions in a compact body.

Key functions

Provides clean, stable and lubricated air
Ensures component durability and reliability
Reduces potential system failures
A properly sized FRL is a strategic investment, not an operating cost.

DISCOVER THE FRL SYSTEM

The FRL unit is a modular system that combines three essential functions to condition compressed air, ensuring it is clean, stable and properly lubricated.

Filter

Barrier against contaminants

Removes solid particles (down to 5 µm), condensate and oil impurities through a combined system of cyclonic separation and porous filtration. Cyclonic separation uses centrifugal force to separate heavier particles, while the filter element captures finer particles.

Filtration5 / 25 / 40 µm
Condensate drainautomatic or manual

Regulator

Stability and operational precision

Maintains constant working pressure regardless of inlet pressure fluctuations. A balanced diaphragm and calibrated spring ensure precise regulation with a maximum variation of ±2%. Eliminates pulsations that can damage downstream components.

Range0.5 – 10 bar
Accuracy±2% of setpoint
L

Lubricator

Active protection of moving parts

Uses the Venturi effect to atomize micro-droplets of oil into the compressed air. This oil mist reaches and lubricates seals, valves and all components with moving parts, reducing friction and preventing wear. Dosage is adjustable according to requirements.

Dosage1-2 drops/min
Recommended oilISO VG 32

THE INVISIBLE ENEMY

Untreated compressed air is the main cause of failures and machine downtime.

⚠ WITHOUT FRL

Untreated compressed air contains particles, condensate and contaminants that progressively damage pneumatic components.
