Airline Pressure Regulators

Stable Air Pressure for Pneumatic Machines and Tools

Airline pressure regulators reduce and control downstream compressed air pressure so pneumatic equipment receives a more consistent operating supply. The NAR series can be used as a standalone regulator or combined with compatible filters and lubricators in a modular FRL assembly.

The source description lists adjustment from 0 to 150 psi(g). Close-coupled assembly can simplify piping and create a compact air-preparation station at the machine or point of use.

Pressure Regulator Features

  • Adjustable downstream pressure
  • 0–150 psi(g) adjustment range listed in the source description
  • Standalone or modular FRL installation
  • Compatible close-coupling with filters and lubricators
  • Suitable for machine-level compressed air control
  • Compact installation for OEM equipment

Why Regulate Compressed Air Pressure?

  • Many pneumatic components perform best when supplied at a controlled pressure rather than the full plant-air pressure.
  • Correct pressure regulation can improve consistency, reduce unnecessary air consumption and protect equipment from being operated above its intended setting.

Common Applications

  • Industrial automation machinery
  • Pneumatic cylinders and actuators
  • Packaging and assembly equipment
  • Air tools and workstations
  • OEM machinery
  • General compressed air distribution

Frequently Asked Questions

What does an airline pressure regulator do?

It reduces inlet compressed air to an adjustable downstream pressure for the pneumatic equipment it supplies.

What adjustment range is listed for the NAR series?

The source description lists adjustment from 0 to 150 psi(g).

Can the regulator be used on its own?

Yes. The NAR series can be used as a standalone regulator or combined with other FRL components.

Can it be assembled with an air filter and lubricator?

Yes. The source description notes close-coupled assembly with compatible filters and lubricators.

Why not run every machine at full plant-air pressure?

Many components only need a lower operating pressure. Regulation can improve consistency and reduce unnecessary compressed air use.

Where should a regulator be installed?

It is normally installed upstream of the equipment that needs controlled pressure, often after filtration.

How do I choose the correct regulator size?

Match port size and flow capacity to the machine demand while considering inlet pressure, required outlet pressure and acceptable pressure drop.

Do I need a gauge with a regulator?

A pressure gauge is commonly used to set and verify downstream pressure when the regulator design provides a suitable gauge port.
