About the Airtac GAC F.R.L. Unit GAC400N10LNWK
Delivering cleaned, regulated and lubricated air, this AirTAC F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket with quick mounting clamps. This specific GAC400N10LNWK variant features a 3/8in port, a 5 um element, and a nylon bowl, operating within the lower pressure range of 0.15-0.4 MPa (20-58 psi).
Air passes through the filter first, then the regulator, before oil mist is introduced downstream by the lubricator, ensuring the regulator seat stays clean. A 5 um element traps fine particles for precision pneumatics, and the reverse-flow (reflux) valve is fitted, which the catalogue shows as a separate pneumatic symbol with details on its own page.

Figures are the end of the flow curve plotted in the AirTAC catalogue at 0.7 MPa inlet pressure — a sizing envelope for comparing bodies, not a rated flow. Read the catalogue curve for a real duty point. Outlet pressure falls as flow rises, so size a body with headroom above your peak demand.

Where the Airtac GAC F.R.L. Unit GAC400N10LNWK Is Used
Precision Valve Arrays
Feeds sensitive directional valves requiring low-pressure, finely filtered 5 um air to prevent sticking and ensure accurate shifting.
Laboratory Pneumatics
Conditions supply air for delicate test fixtures operating safely below 0.4 MPa, adding controlled lubrication for moving actuators.
Light-Clamp Packaging
Regulates low-pressure air for packaging lines where gentle product handling requires stable, reduced force from gripper cylinders.
Is the Airtac GAC F.R.L. Unit GAC400N10LNWK the Right Air-Prep Unit?
Choose this 2390 g unit for medium-duty circuits requiring fine filtration and low-pressure regulation. The 100 cc drain bowl and 185 cc oil bowl dictate the maintenance interval, requiring fewer interventions than a smaller GAC300. No gauge is supplied, but a 1/4in gauge connection allows adding one later to read the set pressure. If the downstream line must remain oil-free, omit the lubricator and choose a filter-regulator instead. The spares path uses GAF400-10, GAR400-10 and GAL400-10. Remember that 0.4 MPa is 44% of the Standard type's 0.9 MPa ceiling, so confirm your machine will never need higher pressure before specifying this L type.
Quick checklist
- ✓ Body size for your peak flow (3/8" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: PC (blank), Metal (C), Nylon (N)
- ✓ Drain: semi-auto + manual, or automatic
- ✓ Element 40 µm or 5 µm
- ✓ Thread & gauge scale (PT / G / NPT)
Installation & Maintenance Notes
- check Install with the airflow arrow: filter first, lubricator last.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Fill the oil bowl with ISO VG 32 or equivalent only.
- check Drain condensate before the 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 2390 g unit on its bracket, not on the tubing.
The lubricator adds an oil mist downstream of the regulator. If any part of the line must stay oil-free, use a filter-regulator instead of an F.R.L. combination on that branch.
Airtac GAC F.R.L. Unit GAC400N10LNWK FAQ
This lower-pressure type operates at 0.15-0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It features a 3/8in port, a 5 um element, a nylon bowl, and a semi-auto + manual drain. The drain bowl holds 100 cc and the oil bowl holds 185 cc. The unit weighs 2390 g, runs on air at -5 to 70 C, and uses ISO VG 32 lubricant.
The N in the model code indicates no gauge is supplied from the factory. The body features a 1/4in gauge connection, allowing you to install a compatible pressure gauge separately to monitor the 0.15-0.4 MPa operating range.
