SPEEDAIRE 4ZL78 air compressor lubricator 1/4 in 60 cfm 250 psi

SKU CH-4HQ6-K43PB

Delivers micro-mist lubrication to pneumatic tools at up to 60 cfm and 250 psi

  • Micro-mist lubrication extends tool life
  • 60 cfm maximum flow supports high-demand air lines
  • 250 psi operating pressure handles heavy-duty applications
  • Aluminium body and bowl resist corrosion
  • Screwdriver adjustment allows precise oil delivery

SPEEDAIRE 4ZL78 Air Line Lubricator

The SPEEDAIRE 4ZL78 is a micro-mist lubricator designed for compressed-air systems that require consistent oil delivery to pneumatic tools. It suits maintenance technicians and shop operators who need reliable lubrication in a compact inline unit. The 1/4-inch NPT female inlet connects directly to standard air lines without extra adapters. This new unit is ready for immediate installation on intermediate-duty circuits.

Aluminium Body with Sight Gauge and Dome

The lubricator body and bowl are constructed from aluminium for corrosion resistance in shop environments. A built-in sight gauge and clear sight dome let operators confirm oil level and mist flow at a glance without interrupting work. Flow direction is fixed left-to-right, simplifying plumbing layout on a bench or wall manifold. The screwdriver-adjustable needle valve uses a PE mechanism for fine metering adjustments.

Replaces Worn or Missing Inline Lubricators

This unit replaces a failed or absent lubricator on lines running up to 60 cfm at 250 psi and 175 degrees F. The upgrade is worthwhile when tool wear or inconsistent performance signals insufficient oil delivery. It is not suited for high-volume mains exceeding the rated flow or for systems that require automatic drain bowls. Buyers needing larger port sizes or higher capacity should select a different series.

Questions about this item

What does the 1/4 in NPT inlet mean for my air line?

The 1/4 inch NPT female inlet threads onto standard 1/4 inch NPT male fittings, and the unit is rated for up to 60 cfm flow at 250 psi maximum pressure.

How much space does the 2 11/16 in wide body need for mounting?

The aluminum body measures 2 11/16 inches overall width, so allow at least that clearance plus room for the sight dome and gauge on the side.

How do I set the oil feed with the screwdriver adjustment?

Insert a screwdriver into the PE adjustment mechanism and turn slowly while watching the sight dome; the common mistake is opening it too far, which floods the line instead of delivering a micro mist.
