SPEEDAIRE 4ZL80 3/8 in Lubricator
The SPEEDAIRE 4ZL80 is a micro-mist air line lubricator built for compressed-air systems that require a 3/8 in NPT female inlet. It suits workshops and light-industrial lines needing consistent oil delivery to pneumatic tools. Aluminium body and bowl construction resists corrosion in typical shop environments. The unit is new and ships in original packaging.
75 cfm at 250 psi Operating Limits
Maximum flow is rated at 75 cfm with a peak operating pressure of 250 psi, so the lubricator must not be installed downstream of compressors or regulators that exceed these values. Temperature ceiling is 175 °F; systems running hotter need cooling or a different lubricator. Left-to-right flow direction is fixed, so pipe layout must match the arrow on the body. California Proposition 65 warnings apply to chemicals present in the materials.
Screwdriver Adjustment and Installation Notes
Oil feed rate is set by a screwdriver-adjustable mechanism with a polyethylene knob; no special tools are required beyond a flat blade. Sight dome and sight gauge are included, allowing visual confirmation of mist density during commissioning. Common issues include over-tightening the bowl onto the aluminium threads, which can strip the soft metal, and forgetting to align the flow arrow, which stops lubrication entirely. Bowl removal for refill needs only hand pressure once the system is depressurised.

Questions about this item
How do I choose between the available versions of the 4ZL80 lubricator?
The 4ZL80 is supplied as a single configuration with a 3/8 in NPT inlet, 75 cfm maximum flow and 250 psi maximum pressure, so there are no alternate versions or capacities to select.
What does the 75 cfm rating mean when the lubricator is installed in my compressed air system?
It indicates the maximum volume of air the unit can pass while delivering micro-mist lubrication; your compressor and downstream tools must operate at or below this flow to maintain proper oil delivery.
How does the 3/8 in NPT inlet limit the fittings and hose I can use?
The female 3/8 in NPT threads accept only matching male NPT fittings, so hose and couplers must be sized to 3/8 in NPT to connect without adapters.
