About the Airtac GAC F.R.L. Unit GAC400N15SWK
Delivering cleaned, regulated and lubricated air for demanding pneumatics, this AirTAC unit integrates a filter, regulator and lubricator on a single L-shape bracket. The 1/2in ported body operates at 0.15-0.9 MPa (20-130 psi) and utilizes a 5 um element to capture fine particulates before they reach sensitive valves. A circular gauge is fitted, reading MPa/psi for the default PT thread.
Air passes through the filter first, then the regulator, ensuring oil mist is added last so the regulator seat never fouls. The 2390 g assembly features a nylon bowl and a reverse-flow (reflux) valve, which the catalogue shows as a separate pneumatic symbol with details on its own page. Condensate is managed by a semi-auto and manual drain combination, holding up to 100 cc of water.

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 GAC400N15SWK Is Used
CNC Tool Changing
Feeds precision valve islands on machining centers where the 5 um element protects tight tolerances from particulate fouling.
Form Fill Seal Lines
Conditions air for high-speed packaging actuators, with the 100 cc drain bowl catching condensate during long production runs.
Automotive Assembly Robots
Supplies clean, lubricated air to robotic grippers and spot-welding cylinders, utilizing the fitted gauge to verify set pressure.
Is the Airtac GAC F.R.L. Unit GAC400N15SWK the Right Air-Prep Unit?
Choose this 1/2in ported body when a machine requires precision filtration, as the 5 um element traps far finer particles than the standard 40 um grade, at the cost of more frequent element service. The nylon bowl offers a lightweight alternative to metal or PC, sharing the same 1.0 MPa maximum pressure and -5 to 70 C temperature limits. If the downstream line must remain oil-free, omit the lubricator and choose a filter-regulator instead.
Spares are separately orderable as GAF400-15, GAR400-15 and GAL400-15. Stepping down to a GAC300 drops the plotted flow envelope from 6000 L/min to 3000 L/min at 0.7 MPa inlet, exactly half the capacity. Stepping up to a GAC500 offers 7000 L/min. The 1.5 MPa proof pressure provides a 1.5x burst-test margin over the 1.0 MPa maximum, but this is not permission to run above 1.0 MPa.
Quick checklist
- ✓ Body size for your peak flow (1/2" 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 GAC400N15SWK FAQ
This standard type unit regulates from 0.15-0.9 MPa (20-130 psi) with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C, weighs 2390 g, and features a 100 cc drain bowl with a 185 cc oil bowl. The recommended lubricant is ISO VG 32.
The K signifies that a reverse-flow (reflux) valve is fitted. The catalogue illustrates this as a distinct pneumatic symbol, and its specific operational details are found on its own dedicated page.
