Airtac GAC F.R.L. Unit GAC400N10SWK
The AirTAC Airtac GAC F.R.L. Unit GAC400N10SWK 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 - 0.9 MPa (20 - 130 psi).

About the Airtac GAC F.R.L. Unit GAC400N10SWK
Delivering cleaned, pressure-set and lubricated air for mid-size pneumatics, this GAC400 unit combines a filter, regulator and lubricator on a single L-shape bracket. The 3/8in port serves machines needing a 5 um element to trap fine particles before they reach precision valves. A circular gauge is fitted, reading MPa/psi for the default PT thread, so operators can verify the 0.15-0.9 MPa (20-130 psi) setting at a glance.
The nylon bowl equips this assembly for environments where PC might be unsuitable, though the -5 to 70 C thermal limit and 1.0 MPa max pressure remain identical across all materials. A semi-auto drain pairs with a manual override to empty the 100 cc condensate bowl, while the 185 cc oil reservoir feeds downstream moving parts. This specific configuration includes a reverse-flow (reflux) valve, which the catalogue shows as a separate pneumatic symbol with details on its own page.

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 GAC400N10SWK Is Used
CNC Tool Changing
Feeds clean, lubricated air at a stable pressure to tool changer cylinders on machining centres, protecting fine tolerances with its 5 um element.
Flow Wrapper Sealing
Conditions air for high-speed packaging line sealing jaws, ensuring consistent actuation speeds and preventing particulate ingress into guiding valves.
Lab Pneumatic Rails
Supplies regulated, finely filtered air to analytical instrument rails where nylon bowls offer compatibility with specific room cleaning agents.
Is the Airtac GAC F.R.L. Unit GAC400N10SWK the Right Air-Prep Unit?
Choose this 2390 g assembly when a 3/8in line requires fine 5 um filtration and a nylon build. The 5 um element catches far finer particulate than the standard 40 um grade, ideal for instrument air, at the cost of more frequent element service. Stepping down to a GAC300 shrinks the condensate bowl to 60 cc and halves the plotted flow envelope to 3000 L/min at 0.7 MPa inlet, whereas this body extends to 6000 L/min. If the downstream line must stay completely free of oil, omit the lubricator and choose a dedicated filter-regulator instead. For maintenance, the three units are separately orderable as GAF400-10, GAR400-10 and GAL400-10. The 1.5 MPa proof pressure provides a 1.5x burst-test margin above the 1.0 MPa maximum, but this is strictly a safety boundary, not permission to run above 1.0 MPa.
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 GAC400N10SWK FAQ
This standard type operates at 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and a 1.5 MPa (215 psi) proof pressure. The temperature range is -5 to 70 C, the filtering grade is 5 um, and it uses ISO VG 32 lubricant. It features a 100 cc drain bowl, a 185 cc oil bowl, and weighs 2390 g.
The K indicates that a reverse-flow (reflux) valve is attached to the unit. The catalogue displays this as a distinct pneumatic symbol, and you should consult that specific page for functional details regarding its operation.
