Prevost Filter-Regulator-Lubricator Manual Valve

Description

Prevost FRL Assembly + Safety Valve & Dry Air Outlet

(4-Unit Station: Valve + Filter-Regulator + Diverter + Lubricator)

The Ultimate Dual-Purpose Workstation: Safety, Treatment, & Versatility

Maximize the functionality of your air drop with this comprehensive Prevost 4-Unit Assembly. This all-in-one station is engineered to solve the common workshop dilemma: needing lubricated air for power tools and clean, dry air for blow guns—all from a single location.

By integrating a Diverter Block between the Filter-Regulator and the Lubricator, this smart configuration gives you two distinct air supplies. You get a “Dry” outlet for tasks like cleaning or tire inflation, while the main line continues through the Lubricator to protect your impact wrenches and grinders. Fronted by a safety shut-off valve, this is the complete package for professional industrial environments.

The 4-Stage Breakdown

1. Manual Shut-Off Valve (Safety First):
   • The entry point of the system. A 3-way, lockable valve that allows you to instantly shut off supply and exhaust downstream pressure. Fully OSHA Lockout/Tagout (LOTO) compliant for safe maintenance.
2. Filter-Regulator (Clean & Stable):
   • Removes moisture, dust, and pipe scale (25µm) while stabilizing the air pressure to your desired setting.³ This ensures that all air moving past this point is clean and controlled.
3. Diverter Block (The “Dry” Outlet):
   • The Game Changer: positioned after the filter but before the lubricator. This module provides threaded ports to tap off Clean, Regulated, Non-Lubricated Air. Perfect for connecting a blow gun, paint prep hose, or tire inflator without contaminating them with oil.
4. Lubricator (Tool Protection):
   • The final stage for the main line. It injects a precise oil mist into the air specifically for your pneumatic motors (drills, impacts, sanders), drastically extending their lifespan and preventing rust.

Key Features & Benefits

• Dual Air Supply: Eliminates the need for two separate drops. Run your impact gun (Oiled) and your blow gun (Dry) from one station.
• Total System Safety: The integrated lockable valve ensures the entire station can be isolated and depressurized in seconds.
• Space-Saving Design: Utilizes the “piggyback” Filter-Regulator to keep the assembly compact, even with 4 distinct modules.
• Modular Flexibility: Built on the ALTO platform, allowing for easy expansion or maintenance of individual units without disassembling the piping.
• Cost Efficiency: Reduces installation time and piping costs by consolidating all air treatment needs into one assembly.

Ideal Applications

• Automotive Bays: Use the main line to power an impact wrench (needs oil) and the diverter port for a tire inflator (must have no oil).
• Manufacturing Benches: Run a pneumatic screwdriver (lubricated) while having a blow gun available for parts cleaning (dry).
• Paint Prep Areas: Use the dry outlet for dusting off parts without risking oil contamination on the surface (Note: Fine coalescing filter recommended for paint).
• General Maintenance: A “do-it-all” station that covers every pneumatic requirement in one spot.

Installation Tip: When plumbing this unit, remember:

• Main Output (End): Connect your air tool hoses here.
• Diverter Block (Middle): Install a coupler here for your blow guns or air nozzles. (Note: You may need a nipple/adapter to fit a coupler into the diverter block ports).
