The Speedaire 4ZL90 Micro Mist Lubricator injects a fine oil mist into a compressed-air line to lubricate downstream components, helping reduce wear and maintain smooth operation of pneumatic tools. It uses a 3/8" NPT inlet fitting and is rated for service up to 250 psi, with an airflow capacity typically listed at 120 cfm for compatible systems. As a lubricator in Speedaire's FRL family, the 4ZL90 delivers lubricant downstream to tools and cylinders, supporting reliable operation in shop air lines. Common applications include pneumatic hand tools, air cylinders, and other air-powered equipment where periodic lubrication is required.
