About the Airtac GAC F.R.L. Unit GAC400N15AS
Delivering cleaned, regulated and lubricated air for demanding pneumatic setups, this AirTAC unit combines a filter, regulator and lubricator on a single L-shape bracket. The 1/2in port serves mid-to-large machinery, while the standard pressure range operates between 0.15-0.9 MPa (20-130 psi). A 40 um element captures solid particles, and the nylon bowl provides a durable housing for the 100 cc condensate capacity.
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. Because this specific configuration uses an automatic drain, condensate is expelled without an operator present, making it highly suitable for unattended or wet air lines. The assembly weighs 2390 g, requiring a solid panel or frame mount rather than relying on the connected tubing for support.

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 GAC400N15AS Is Used
Automotive Assembly Lines
Feeds multiple pneumatic actuators and presses on a vehicle manufacturing line, utilizing the 1/2in port to maintain steady airflow and the auto drain to handle high condensate volumes.
Case Erector Machinery
Provides consistent oil-misted air for the high-speed moving parts and cylinders in cardboard packaging equipment, preventing seal wear during continuous operation.
Textile Manufacturing
Conditions air for looms and spinning frames where moisture and particulates could ruin delicate fibers, relying on the 40 um element to protect downstream valves.
Is the Airtac GAC F.R.L. Unit GAC400N15AS the Right Air-Prep Unit?
Choose this GAC400 body for applications needing substantial air preparation, stepping up from the GAC300 which offers a 60 cc drain bowl. The nylon bowl on this model offers a lightweight alternative to metal, sharing the same 1.0 MPa maximum pressure and -5 to 70 C temperature limits. A circular gauge is fitted, reading MPa/psi for the default PT thread, allowing operators to monitor the set pressure directly. If your downstream line must remain oil-free, omit the lubricator and choose a filter-regulator instead. For maintenance, the three units are separately orderable as GAF400-15, GAR400-15 and GAL400-15. The catalogue flow curve for the GAC400 is plotted to 6000 L/min at 0.7 MPa inlet, which is double the 3000 L/min envelope of the GAC300, giving you significant sizing headroom. Keep in mind the proof pressure of 1.5 MPa against the 1.0 MPa maximum provides a 1.5x burst-test margin, 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 GAC400N15AS FAQ
This F.R.L. combination uses air with a 40 um filtering grade. The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The operating temperature is -5 to 70 C, and the recommended lubricant is ISO VG 32. It features a 100 cc drain bowl, a 185 cc oil bowl, and weighs 2390 g.
The automatic drain clears condensate from the 100 cc bowl whenever it accumulates, eliminating the need for manual intervention on unattended shifts. The nylon bowl material provides a robust, shatter-resistant alternative to standard PC, though buyers should confirm chemical compatibility for aggressive surroundings as no solvent data is printed.
