1/2 in NPT air line lubricator

The SPEEDAIRE 4ZL87 lubricator introduces oil mist into a compressed air line with a 1/2 in NPT inlet and a maximum flow of 80 cfm. It is intended for workshops and light industrial sites that need consistent tool lubrication.

Aluminium body with polycarbonate bowl and steel

The body is aluminium and the bowl is polycarbonate protected by a steel guard, rated for 150 psi and 125 Degrees F. A sight dome and sight gauge let the operator confirm oil delivery at a glance, while a screwdriver-adjustable mechanism controls the feed rate.

Left-to-right flow with included sight components

The unit ships with the sight dome and sight gauge already fitted, so installation only requires plumbing the NPT connections in the marked left-to-right direction. No separate lubricator oil or mounting brackets are supplied in the package.

Questions about this item

What does the 1/2 in NPT inlet and 80 cfm rating mean for my air line?

The 1/2 in NPT inlet matches standard fittings, and the 80 cfm maximum flow rate sets the practical limit for tools or runs you can supply without pressure drop.

What space and bowl material do I need to allow for when mounting this lubricator?

The body is 3 1/8 in wide with a polycarbonate bowl protected by a steel guard, so allow that width plus clearance for bowl removal and sight gauge viewing.

How do I set the oil feed correctly and what is the common mistake?

Use a screwdriver on the PE adjustment mechanism to set the mist rate; the common mistake is adjusting while the system is pressurised instead of depressurised.
