About the Airtac GAFC Air Service Unit GAFC400N15ALNK
This AirTAC GAFC400N15ALNK is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator is mounted downstream on a T-bracket with quick clamps. It handles a 1/2in port, regulates from 0.15 to 0.4 MPa (20-58 psi), and filters to 40 um.
The nylon bowl holds 100 cc of condensate, while the oil bowl holds 185 cc, and the unit weighs 1810 g. The automatic drain clears water without an operator, and the reverse-flow valve is fitted. No gauge is supplied; the 1/4in gauge connection is ready for an add-on if needed.

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 GAFC400N15ALNK Is Used
Precision Pressure Setting
Set a precise 0.3 MPa (43 psi) for a delicate clamping fixture on a CNC machine, where the lower range gives finer adjustment than a standard regulator.
Unattended Assembly Line
Feed a multi-station assembly line with a 1/2in header, relying on the automatic drain to clear condensate from the 100 cc bowl without daily checks.
Low-Pressure Test Rig
Supply a test rig that validates components at 0.2 MPa (29 psi), using the 185 cc oil bowl to lubricate downstream pneumatic tools consistently.
Is the Airtac GAFC Air Service Unit GAFC400N15ALNK the Right Air-Prep Unit?
Choose this GAFC400N15ALNK for a 1/2in line needing lower regulated pressure, topping out at 0.4 MPa (58 psi). The nylon bowl is a build choice, not a performance upgrade, so confirm it suits your environment. The automatic drain suits unattended machines, and the 40 um element is the standard grade. The PT thread carries a MPa/psi scale if you add a gauge later. The reverse-flow valve is fitted, and the catalogue shows it as a separate symbol. Spares are the GAFR400-15 filter-regulator and the GAL400-15 lubricator, both orderable separately. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the range, so plan the inlet pressure accordingly.
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-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 GAFR400-15 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC400N15ALNK FAQ
This F.R.L. combination operates at 0.15-0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It works from -5 to 70 C, has a 100 cc drain bowl and a 185 cc oil bowl, and weighs 1810 g. Use ISO VG 32 oil in the lubricator.
The N after the port code means no gauge is supplied. The 1/4in gauge connection is still there, so you can add a circular gauge with an MPa/psi scale if you need to read the set pressure directly. The N before the port code means the bowl is nylon, not PC.
