Airtac GAC F.R.L. Unit GAC400C15ASK
The AirTAC Airtac GAC F.R.L. Unit GAC400C15ASK 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 1/2" ports, a 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAC F.R.L. Unit GAC400C15ASK
Delivering cleaned, regulated and lubricated air for demanding pneumatic setups, this AirTAC F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket. The 1/2in port pairs with a standard 0.15-0.9 MPa (20-130 psi) operating range and a 40 um element. Because the assembly arrives pre-plumbed via quick mounting clamps, installers avoid inter-unit tubing leaks and only need to secure one bracket to the panel. The 2390 g mass dictates a firm frame mount rather than relying on downstream piping for physical support.
Air travels through the filter, then the regulator, and finally the lubricator, ensuring oil mist is added downstream so the regulator seat never fouls. This specific configuration uses a robust metal bowl and an automatic drain that expels condensate without an operator, which is highly effective for unattended machinery. A circular gauge is fitted to read the set pressure in MPa/psi, and the reverse-flow (reflux) valve is included, shown in the catalogue as a separate pneumatic symbol. If the application requires completely oil-free downstream air, omit the lubricator and select a standalone filter-regulator instead.

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 GAC400C15ASK Is Used
Automotive Assembly Lines
Feeds main air headers for robotic welding cells where a 1/2in supply and automatic condensate removal keep heavy-duty cylinders running without manual intervention.
Case Erector Machines
Provides consistent 0.9 MPa air and oil mist to the folding and sealing actuators, preventing premature wear on high-speed moving parts.
CNC Tooling Preparation
Conditions air for automatic tool changers and pneumatic clamps, ensuring the 40 um element captures debris before it reaches precision valves.
Is the Airtac GAC F.R.L. Unit GAC400C15ASK the Right Air-Prep Unit?
Choose this GAC400 size class when a 1/2in port is required but the 3/8in GAC400 option is too restrictive, or step up to the GAC500 with its 3/4in port if the line demands a higher flow envelope (plotted to 7000 L/min at 0.7 MPa inlet versus 6000 L/min here). The metal bowl offers durability for harsh environments, while the automatic drain clears the 100 cc condensate sump autonomously. The standard 40 um element suits general plant air, but precision valves might need the 5 um W option. The fitted gauge reads in MPa/psi for the default PT thread, and the reverse-flow valve is attached. Should a component fail, order the exact spares GAF400-15, GAR400-15 and GAL400-15. Remember that the 1.5 MPa (215 psi) proof pressure provides a 1.5x burst-test margin over the 1.0 MPa (145 psi) 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.
