About the Airtac GAC F.R.L. Unit GAC400N15S
Delivering cleaned, regulated and lubricated air for demanding pneumatics, this AirTAC GAC400N15S combines a filter, regulator and lubricator on a single L-shape bracket. The 1/2in port serves mid-to-high flow requirements, while the standard pressure type operates from 0.15-0.9 MPa (20-130 psi). A 40 um element captures solid particulates, and the assembly features a nylon bowl to visually monitor condensate and oil levels.
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 unit requires a solid panel or frame mount rather than tubing support. The 100 cc drain bowl and 185 cc oil reservoir dictate the maintenance frequency, and the fitted circular gauge reads MPa/psi for the default PT thread.

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 GAC400N15S Is Used
Automotive Assembly Lines
Feeds main air headers for robotic welding cells and stamping presses where a steady 1/2in supply is necessary to maintain cycle speed.
Boxing and Palletizing
Conditions air for high-speed case erectors and pallet wrappers that rely on continuous actuation and require consistent oil mist for pneumatic grippers.
CNC Machine Tooling
Prepares supply air for tool changers and automatic bar feeders, protecting precision valves from particulate ingress with a 40 um filter.
Is the Airtac GAC F.R.L. Unit GAC400N15S the Right Air-Prep Unit?
Choose this 1/2in port body for applications needing more air capacity than the GAC300 offers; the catalogue flow curve for the GAC400 is plotted to 6000 L/min at 0.7 MPa inlet, double the 3000 L/min envelope of the GAC300. This model uses a nylon bowl, a 40 um element, and ships with both semi-auto and manual drains. The semi-auto option dumps condensate on every pressure drop, while the manual option allows on-demand emptying. Because the lubricator introduces oil into the line, select a filter-regulator instead if your downstream tools require oil-free air. Should a component fail, order spares using the same body-port suffix: GAF400-15, GAR400-15 and GAL400-15. Keep in mind that the 1.5 MPa proof pressure provides a 1.5x burst-test margin over the 1.0 MPa maximum, which 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 GAC400N15S FAQ
This unit operates at 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 functions in temperatures from -5 to 70 C, weighs 2390 g, and uses a 100 cc drain bowl alongside a 185 cc oil bowl. The recommended lubricant is ISO VG 32.
The N before the port designates a nylon bowl, which allows visual inspection of the fluid levels. Because there is no A in the code, it ships with both a semi-auto drain that expels condensate on pressure drops and a manual drain for operator-controlled emptying.
