About the Airtac GAC F.R.L. Unit GAC400N10ASNK
Delivering cleaned, regulated and lubricated air, this AirTAC GAC400N10ASNK is a complete three-unit F.R.L. combination pre-plumbed on a single L-shape bracket. The 3/8in port feeds a standard pressure range of 0.15-0.9 MPa (20-130 psi) through a 40 um element. Because the lubricator sits last in the sequence, oil mist is introduced downstream of the regulator seat, preventing fouling of the internal mechanism.
The nylon bowl houses an automatic drain that expels condensate without an operator, which is critical for unattended or wet lines. No gauge is supplied, but the body features a 1/4in gauge connection if you need to add instrumentation later. A reverse-flow (reflux) valve is fitted, shown as a separate pneumatic symbol in the catalogue. Weighing 2390 g, this assembly requires a rigid panel or frame mount rather than tubing 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 GAC400N10ASNK Is Used
Automotive Assembly Lines
Feeds multiple pneumatic wrenches and actuators on a vehicle production line, relying on the automatic drain to handle moisture during continuous shift operations.
Boxing and Palletizing
Provides consistent 0.9 MPa air for high-speed packaging cylinders, ensuring the lubricator delivers a steady oil mist to fast-moving seals.
CNC Tool Changers
Conditions air for pneumatic tool changer arms on machining centers, where the 40 um element protects precision valves from particulate ingress.
Is the Airtac GAC F.R.L. Unit GAC400N10ASNK the Right Air-Prep Unit?
This model uses a nylon bowl and an automatic drain, making it suitable for environments where condensate accumulates continuously and manual draining is impractical. If your downstream process cannot tolerate oil mist, you must omit the lubricator and choose a filter-regulator instead. The three constituent parts are separately orderable as GAF400-10, GAR400-10 and GAL400-10, so a damaged bowl or clogged element does not require replacing the whole assembly. Stepping up to the GAC500 body increases the flow envelope from 6000 to 7000 L/min at 0.7 MPa inlet, while dropping to the GAC300 reduces it to 3000 L/min. When sizing your supply, remember that the 1.0 MPa maximum inlet pressure leaves only 0.1 MPa of headroom above the 0.9 MPa standard setting.
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 GAC400N10ASNK 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). The temperature range is -5 to 70 C. It features a 100 cc drain bowl and a 185 cc oil bowl, weighs 2390 g, and uses ISO VG 32 lubricant.
The N in the code means no gauge is supplied, though a 1/4in connection is available if you need to add one to read the set pressure. The K indicates a reverse-flow (reflux) valve is fitted, which the catalogue shows as a separate pneumatic symbol with details on its own page.
