About the Airtac GAFC Air Service Unit GAFC400N10ALNK
This GAFC400N10ALNK is a two-piece F.R.L. combination: a GA-series filter-regulator (the filter and regulator share one body) paired with a GA-series lubricator on a T-shape bracket with quick clamps. The 3/8in port and 1810 g mass put it in the mid-size class, a step up from the GAFC300's 1020 g for lines that need more condensate and oil capacity.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 1.0 MPa (145 psi) maximum supply and 1.5 MPa (215 psi) proof pressure. The 40 um element handles standard shop air, the automatic drain clears the 100 cc condensate bowl without an operator, and the 185 cc oil bowl feeds ISO VG 32 lubricant. No gauge is fitted; the 1/4in gauge connection is ready for one if you add it later.

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 GAFC Air Service Unit GAFC400N10ALNK Is Used
Precision valve actuation
Feed a bank of small pneumatic valves on a packaging line where the lower 0.4 MPa ceiling protects delicate actuators from over-pressure.
Machine tool coolant control
Supply filtered, regulated air to coolant valves on a CNC lathe, with the automatic drain handling condensate from a humid shop floor.
Assembly station air prep
Prepare air for a bench-top press or torque tool on an assembly line, where the 185 cc oil bowl keeps the lubricator running between shifts.
Is the Airtac GAFC Air Service Unit GAFC400N10ALNK the Right Air-Prep Unit?
The GAFC400 body offers 3/8in and 1/2in ports; this 3/8in version suits feeds to a single machine station or a small header. The L type tops out at 0.4 MPa, so if your process may ever need more than that, step up to the S type (0.15-0.9 MPa) instead. The nylon bowl is a build choice - the common specification (1.0 MPa max, -5 to 70 C) is identical across PC, metal and nylon, so confirm it suits your surroundings. The automatic drain is the right pick for unattended or wet lines, while the 40 um element is the standard grade. The reverse-flow (reflux) valve is fitted, and the PT thread carries a gauge scale in MPa/psi if you add the optional gauge. Spares are orderable as GAFR400-10 and GAL400-10. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan your inlet pressure with that margin in mind.
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-regulator 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 1810 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 plain GAFR400-10 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC400N10ALNK FAQ
This F.R.L. combination operates at 0.15-0.4 MPa (20-58 psi) with a maximum supply of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C, and it uses ISO VG 32 lubricant. The drain bowl holds 100 cc and the oil bowl 185 cc, with a total weight of 1810 g. The 40 um element filters the air, and the automatic drain clears condensate without manual attention.
The N after the port code means no gauge is supplied. The GAFC400 body has a 1/4in gauge connection, so you can add a circular gauge later if you need to read the set pressure. The PT thread would use a gauge with an MPa/psi scale.
