Speedaire 4ZL77A Industrial Pneumatic Airline Lubricator

Speedaire 4ZL77A Industrial Pneumatic Airline Lubricator is a mist-type lubrication stage for compressed-air systems, designed to introduce a controlled oil mist downstream to lubricate tools and actuators in busy production environments. This 1/2 in NPT lubricator handles up to 95 cfm of airflow and operates at a maximum of 150 psi, making it suitable for mid-range industrial air lines that feed pneumatic tools, cylinders, and valves. The unit features a durable polycarbonate bowl for oil storage and a simple, field-serviceable metering path that feeds lubricant into the airstream, supporting continuous operation with minimal maintenance. As a component of Speedaire’s FRL (filter-regulator-lubricator) line, it’s intended to be paired with compatible Speedaire filters and regulators to condition air and extend the life of downstream components. Typical applications span automotive repair shops, light manufacturing, and general workshop use where consistent lubrication of air-powered equipment is essential to reduce wear and improve performance. Designed for integration with standard 1/2-inch piping and common air-prep setups.
