Airline Lubricators

Controlled Airline Lubrication for Pneumatic Equipment

Airline lubricators introduce a controlled quantity of oil into the compressed air stream for pneumatic equipment that requires lubrication. The NAL series can be used independently or combined with a compatible filter and pressure regulator in a modular FRL assembly.

The source description notes that the oil drip rate is fully adjustable, allowing the lubrication feed to be matched to the application. Lubrication should only be used where the downstream equipment manufacturer recommends or requires it.

Airline Lubricator Features

  • Adjustable oil drip rate
  • Standalone or modular FRL installation
  • Close-coupled assembly with filters and regulators
  • Point-of-use lubrication for compatible pneumatic equipment
  • Compact industrial air-preparation design

When Is an Airline Lubricator Needed?

  • Some pneumatic tools and components are designed to operate with a small amount of oil carried in the air stream, while many modern components are designed for non-lubricated service.
  • Always follow the equipment manufacturer's lubrication recommendations before adding oil to a compressed air circuit.

Common Applications

  • Pneumatic air tools
  • Industrial automation equipment requiring lubrication
  • Machine tools
  • Assembly workstations
  • OEM machinery
  • Modular FRL air-preparation systems

Frequently Asked Questions

What does an airline lubricator do?

It meters a controlled amount of oil into the compressed air stream for compatible downstream pneumatic equipment.

Is the oil feed adjustable?

Yes. The source description states that the NAL series drip rate is fully adjustable.

Can the lubricator be used by itself?

Yes. It can be installed alone or close-coupled with compatible filters and regulators.

Does every pneumatic system need a lubricator?

No. Only use airline lubrication when the downstream equipment manufacturer recommends it.

Where is a lubricator installed in an FRL?

In a typical FRL arrangement, lubrication is applied after filtration and pressure regulation so the prepared air receives the controlled oil feed before reaching the equipment.

Why use a modular FRL assembly?

Close-coupling reduces interconnecting pipework and creates a compact air-preparation station.

How do I set the lubricator?

Set the drip rate according to the downstream equipment requirement and operating conditions, then verify that excessive oil is not being introduced.

What should I check during maintenance?

Inspect oil level, bowl condition, adjustment and downstream equipment requirements as part of routine service.
