Prevost Lubricator

Description

Prevost ATU Series Air Lubricator

Automatic Protection for Pneumatic Tools & Machinery

Dramatically extend the lifespan of your air tools with the Prevost ATU Series Lubricator. Pneumatic motors, cylinders, and valves require consistent lubrication to function smoothly and prevent internal corrosion.² The ATU Lubricator automates this process by injecting a fine, adjustable mist of oil directly into the air stream, ensuring your equipment is constantly protected from wear and friction.

Part of the modular ATU system, this unit features a precision “Venturi” mechanism that ensures the amount of oil delivered remains proportional to the airflow. Whether you are running a single impact wrench or a high-speed grinder, this lubricator delivers the exact amount of oil needed—no more, no less.

Key Features & Benefits

• Micrometric Adjustment: Features an easy-to-use adjustment screw and a transparent sight dome, allowing you to visually monitor the oil drip rate and fine-tune it for your specific tool requirements.
• Proportional Oil Delivery: The flow sensor technology increases oil output as air consumption rises, maintaining a consistent oil-to-air ratio during heavy usage.
• Extended Tool Life: Prevents the “dry running” that destroys O-rings, vanes, and seals, significantly reducing repair costs and downtime.
• Modular Connectivity: Designed to couple seamlessly with Prevost ATU Filters and Regulators, allowing you to build a compact, all-in-one FRL (Filter-Regulator-Lubricator) station.
• Robust Bowl Options: Available with polycarbonate bowls (for visibility) protected by a casing, or metal bowls for harsh, high-impact environments.

Technical Specifications

Ideal Applications

• Air Tools: Essential for impact wrenches, ratchets, sanders, and grinders.
• Pneumatic Cylinders: Lubricating the seals and sliding surfaces of automation actuators.
• Air Motors: Maintaining high-speed rotary motors in manufacturing equipment.
• Assembly Lines: Ensuring continuous operation of production tools without manual oiling.

Crucial Application Note: Never install a lubricator on an air line intended for paint spraying, breathing air, or tire inflation, as the oil will contaminate the finish or the tire rubber. Lubricators should typically be installed no more than 15-20 feet from the tool for maximum effectiveness.
