SKU CH-S308-QAGRY

Micro-mist lubricator delivers oil to 50 cfm air lines at up to 250 psi with 1/4 in NPT ports and zinc construction

  • Micro-mist design delivers fine oil aerosol for consistent tool lubrication
  • 1/4 in NPT female ports fit standard air-line fittings directly
  • 50 cfm maximum flow supports high-demand pneumatic equipment
  • 250 psi maximum operating pressure handles heavy-duty compressed-air systems
  • Zinc body and bowl resist corrosion in harsh workshop environments

Compact Micro-Mist Lubricator

The SPEEDAIRE 4ZL68 is a compact micro-mist air line lubricator designed for pneumatic systems that require fine oil delivery. It suits maintenance technicians and shop operators who need consistent lubrication for air tools and cylinders in a small footprint.

Build Integration Requirements

The unit installs inline with 1/4 inch NPT female ports and flows up to 50 cfm at 250 psi maximum operating pressure. Its zinc body and bowl handle temperatures to 175 degrees F, while the left-to-right flow direction simplifies piping layout in tight compressor rooms.

Sight Dome and Adjustment Benefits

An included sight dome and sight gauge let operators verify oil delivery at a glance without interrupting flow. The screwdriver adjustment mechanism with PE components provides tamper-resistant control over lubrication rate, reducing the chance of accidental over- or under-oiling during production shifts.

Questions about this item

Will the 50 cfm flow limit restrict my tools during continuous operation?

The lubricator is rated for a maximum flow of 50 cfm, so any tool or circuit demanding more will hit that ceiling first.

How hot can the zinc bowl get before the micro-mist lubricator loses effectiveness?

Maximum operating temperature is 175 °F; sustained heat above that can degrade oil delivery and bowl integrity.

My compressor outlet is 1/4 in NPT female — will this lubricator connect directly?

Yes, the unit has a 1/4 in NPT female inlet and a matching female outlet for in-line installation.
