Arrow L386W Lubricator

Arrow L386W Midflow Arrowfog Lubricator (old 6506W) is a modular air-lubrication device that injects precise amounts of lubrication into a compressed-air line to protect downstream tools and actuators. The unit uses a 20-ounce metal bowl, available with a sight glass option, and a 3/4" NPT inlet/outlet for compatibility with standard air-pipe fittings. With a midflow design, it delivers oil into the airstream at up to 142 CFM and is suited to medium-to-high flow pneumatic circuits. The lubricator is designed for use in industrial settings with an operating temperature range from 40 to 175 °F; it remains functional across typical workshop environments. Physically, it measures about 3-3/4 inches in width and 11-9/16 inches in height, with a length of roughly 3.75 inches, and weighs around 2.6 pounds. Arrow’s L386W is part of the Midflow Arrowfog lubricator family, commonly employed on shop floors and automation cells to extend tool life, reduce wear, and maintain consistent lubrication in air lines for CNC machines, robotic arms, conveyors, and general pneumatic tooling. The model continues to be identified by the part number L386W and is the contemporary successor to the older 6506W designation.
