Airtac GAC F.R.L. Unit GAC400N10LNW
The AirTAC Airtac GAC F.R.L. Unit GAC400N10LNW is a genuine three-unit F.R.L. combination — a filter, a pressure regulator and a lubricator pre-assembled on one bracket with quick mounting clamps. It has 3/8" ports, a 5 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).

About the Airtac GAC F.R.L. Unit GAC400N10LNW
Delivering cleaned, regulated and lubricated air for downstream pneumatics, this AirTAC unit combines a filter, regulator and lubricator on a single L-shape bracket. It features a 3/8in port, a 5 um element and a nylon bowl. The lower-pressure type restricts the operating range to 0.15-0.4 MPa (20-58 psi). Air passes through the filter first, then the regulator, and finally the lubricator, ensuring oil mist is added downstream so the regulator seat never fouls.
Weighing 2390 g, this assembly needs a proper panel or frame mount rather than support from the tubing. It carries a 100 cc condensate bowl and a 185 cc oil reservoir. Because the code includes an N after the port, no pressure gauge is supplied; the 1/4in gauge connection is available if you need to add one later. The 5 um element traps far finer particles than the standard 40 um grade, making it suitable for precision valves, though it requires more frequent service.

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 GAC400N10LNW Is Used
Precision Valve Manifolds
Feeds sensitive directional valves in a machining center using the 5 um element to prevent sticking, while the lower 0.4 MPa pressure protects delicate internal seals.
Low-Force Sealing Jaws
Conditions air for packaging equipment where light gripping forces are required, adding a controlled oil mist to lubricate the small gripper cylinders.
Laboratory Pneumatic Rigs
Supplies clean, regulated air to test fixtures and actuator arrays, relying on the 100 cc drain bowl to capture moisture from intermittent duty cycles.
Is the Airtac GAC F.R.L. Unit GAC400N10LNW the Right Air-Prep Unit?
Choose this lower-pressure type if your machine operates strictly within 0.15-0.4 MPa (20-58 psi); if the application may ever need more, the L type is the wrong part. The semi-auto and manual drain pair is fitted, dumping condensate on each pressure drop or on demand. If the line must stay oil-free, omit the lubricator and choose a filter-regulator instead. For maintenance, the three units are separately orderable as GAF400-10, GAR400-10 and GAL400-10, so a clogged element does not require replacing the whole assembly. The catalogue flow curve for the GAC400 is plotted to 6000 L/min at 0.7 MPa inlet, which is 200% of the GAC300's 3000 L/min envelope. Note that the 0.4 MPa ceiling is 44% of the Standard type's 0.9 MPa maximum.
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 GAC400N10LNW FAQ
This unit 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). The temperature range is -5 to 70 C. It features a 100 cc drain bowl and a 185 cc oil bowl, uses ISO VG 32 lubricant, and weighs 2390 g.
The N in the ordering code indicates no gauge is supplied. The body has a 1/4in gauge connection, allowing you to install a separate gauge reading MPa/psi for the default PT thread if you need to monitor the set pressure.
