Description
Prevost 2-Piece FRL Unit + prevoS1 Safety Coupling
The Complete “Ready-to-Run” Air Treatment Station
Upgrade your workstation instantly with the Prevost 2-Piece FRL Assembly, a pre-assembled, all-in-one solution designed to filter, regulate, and lubricate your compressed air in a single compact package. This unit combines the ALTO series filtration and regulation precision with the legendary safety of the prevoS1 Quick Coupling, giving you a professional air drop that protects your tools and your team from the moment you install it.
This assembly merges the Filter-Regulator (piggyback) into one module and the Lubricator into the second, saving valuable wall space. It comes pre-fitted with a prevoS1 Safety Coupling on the outlet, ensuring that connecting and disconnecting hoses is effortless, leak-free, and completely safe from dangerous “hose whip.”
Key Features & Benefits
- All-in-One Protection:
- Filter: Removes moisture, dust, and pipe scale (typically 25µm) to prevent contamination.
- Regulator: Stabilizes air pressure to ensure consistent tool torque and reduce energy waste.
- Lubricator: Automatically injects a fine oil mist to extend the life of air motors and seals.
- prevoS1 Safety Coupling Included: The outlet features the patented prevoS1 one-touch coupling. A single push depressurizes the hose (eliminating whip) and disconnects it safely, all with an ergonomic composite body that resists scratching surfaces.
- Space-Saving 2-Unit Design: By stacking the Filter and Regulator, this configuration reduces the overall width of the assembly compared to 3-piece units, making it perfect for tight installs.
- Ready for Installation: Comes pre-assembled with a wall mounting bracket, reducing setup time.
- User-Friendly Control: Features a locking pressure knob to prevent accidental changes and a clear sight dome on the lubricator for easy oil flow monitoring.

Ideal Applications
- Mechanic Bays: The perfect single-point station for powering and protecting impact wrenches and ratchets.
- Assembly Benches: Provides regulated, lubricated air for screwdrivers and drills in manufacturing.
- Machine Shops: Ideal for CNC support equipment and deburring stations.
- Mobile Service Trucks: Compact and rugged enough to provide treated air on the go.
Selection Note: Because this unit includes a Lubricator, it must not be used for paint spray guns or tire inflation. Use a separate Filter-Regulator unit (without lubricator) for those clean-air applications.
