3/8 in micro-mist lubricator
The SPEEDAIRE 4ZL70 is a compact inline lubricator designed for compressed-air systems that require a fine oil mist. Its zinc body and NPT female ports suit workshop and light-industrial air lines where consistent lubrication protects downstream tools.
50 cfm flow at 250 psi
Rated for a maximum flow of 50 cfm and a maximum operating pressure of 250 psi, the unit delivers reliable lubrication across typical shop supply pressures. Above that flow or pressure the lubricator reaches its design limit and a larger or higher-rated device would be required.
175 °F operating temperature
The lubricator operates up to 175 °F, with a screwdriver-adjustable metering valve and a clear sight dome for visual confirmation of oil delivery. Zinc construction resists corrosion in normal compressed-air environments while keeping the assembly compact.

Questions about this item
Will the 3/8 in NPT female ports on this SPEEDAIRE 4ZL70 match the fittings on my existing compressor hose?
Yes, the unit has 3/8 in NPT female inlet and outlet threads, the standard size for many shop air lines and quick-connect fittings.
How can I confirm the micro-mist lubricator is delivering oil once installed?
Watch the included sight dome; a steady fog of micro-mist should appear when air flows, and the sight gauge shows the oil level at a glance.
Does the box contain mounting brackets or airline fittings, or must I buy them separately?
The package supplies the lubricator body with sight dome and gauge only; brackets, nipples, couplers and thread sealant are purchased separately.
