Prevost ALTO Filter-Regulator-Lubricator

Description

Prevost ALTO Filter-Regulator-Lubricator (FRL)

The Complete Air Preparation Command Center

The Prevost ALTO Filter-Regulator-Lubricator (FRL) is the ultimate all-in-one solution for managing air quality and tool longevity. By combining three critical functions—filtration, pressure regulation, and lubrication—into a single modular assembly, this unit ensures your compressed air is clean, dry, precisely pressurized, and properly oiled.

This “Complete Air Station” is the gold standard for industrial environments, automotive shops, and manufacturing cells where tool uptime and performance are non-negotiable.

The Three-Stage Protection System

1. Stage 1: Filtration: The high-efficiency filter removes water droplets, oil aerosols, rust, and pipe scale. This prevents the “sludge” that clogs internal tool valves and causes premature wear.
2. Stage 2: Regulation: The integrated regulator provides a rock-steady air supply. By dialing in the exact PSI required for your application, you prevent over-pressurization—the leading cause of seal failure and wasted energy.
3. Stage 3: Lubrication: The micro-mist lubricator delivers a precise, atomized oil spray directly into the air stream. This constant lubrication reduces friction in high-speed rotors and pistons, keeping tools running cool and smooth.

Key Features

• Modular Space-Saving Design: A compact, pre-assembled unit that replaces three separate components, reducing the number of potential leak points and simplifying installation.
• Push-to-Lock Adjustment: The regulator features a tactile locking knob to prevent accidental pressure changes due to vibration or workspace activity.
• Precision Drip Control: The lubricator includes a transparent sight-dome and a needle valve, allowing you to visually calibrate and monitor the exact amount of oil being delivered.
• Rugged Construction: Built with high-strength metallic bodies and polycarbonate bowls protected by reinforced metal guards for maximum impact resistance.
• Easy Maintenance: Features rapid-release bowls for quick filter element changes and a lubricator that can be refilled without depressurizing the entire system.

Why Invest in a Full FRL?

Without an FRL, your air system is working against you. Moisture causes rust, pressure spikes cause mechanical stress, and dry air causes friction. The Prevost ALTO FRL turns “raw” air into a professional utility, significantly lowering your total cost of ownership by doubling the life of your pneumatic tools and reducing expensive emergency repairs.

Ideal Applications

• Pneumatic Tool Stations: For use with impact wrenches, grinders, and air drills.
• Industrial Automation: Protecting cylinders, manifolds, and solenoid valves.
• Woodworking & CNC: Ensuring smooth operation of pneumatic clamps and actuators.
• Heavy Machinery: Providing treated air for high-torque assembly equipment.

Note: The FRL is designed for tools requiring oil. For paint spraying or clean-air applications, the Lubricator stage should be removed or bypassed.
