Speedaire 4Zl57 Lubricator For Pneumatic System

Speedaire 4ZL57 is a compact micro‑mist air‑line lubricator that introduces a fine oil mist into the compressed air stream to lubricate downstream components. With a 1/4 in NPT inlet connection, it is designed for modular inclusion in standard pneumatic FRL systems and is commonly used to supply lubrication to air tools, cylinders, and valves in automation and maintenance environments. The lubricator is specified for an inlet pressure up to 150 psi (10 bar) and a maximum operating temperature of 125°F (50°C), making it suitable for typical workshop and factory conditions. Its flow capacity is listed at 14 CFM, enabling lubrication across standard circuit lengths without excessive oil carryover. Speedaire’s micro‑mist design helps deliver an atomized oil mist downstream, supporting smoother actuation, reduced wear, and sustained performance of pneumatic devices. As part of Speedaire’s line of lubrication components, it is intended to deliver oil to downstream components to improve performance and reduce wear in compressed air systems, helping to maintain reliable operation of pneumatic tools, actuators, and valves in industrial settings.
