About the Airtac GAFC Air Service Unit GAFC400C10ALNK
This GAFC400C10ALNK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a shared T-bracket with quick clamps. Air is cleaned and set to pressure in the first body, then the lubricator adds a metered oil mist downstream, so the regulator seat never sees oil. The 3/8in port and 1810 g mass place it in the mid-size class, needing a proper panel mount rather than tubing support.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 40 um element and an automatic drain that clears condensate without an operator. The metal bowl holds 100 cc, the oil bowl 185 cc, and the gauge connection is 1/4in if one is added later. A reverse-flow valve is fitted, shown as a separate symbol in the catalogue.

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 GAFC400C10ALNK Is Used
Precision valve control
Feed a bank of pneumatic valves on a small assembly station where the lower 0.4 MPa ceiling prevents over-pressurizing delicate actuators.
Machine tool lubrication
Supply a controlled oil mist to a spindle or slideway lubrication system on a CNC lathe, where consistent metering matters more than high flow.
Test rig air supply
Provide filtered, regulated air to a benchtop test fixture that requires a stable 0.3 MPa supply, with the automatic drain handling condensate from a wet compressor line.
Is the Airtac GAFC Air Service Unit GAFC400C10ALNK the Right Air-Prep Unit?
Choose this GAFC400C10ALNK when your line needs a 3/8in port and a regulated ceiling of 0.4 MPa, not the standard 0.9 MPa. The metal bowl is a build choice for the surroundings, but the shared specification (-5 to 70 C, 1.0 MPa max) does not change with material, so confirm compatibility for aggressive environments. The automatic drain suits unattended operation, while the 40 um element handles general shop air; step to the 5 um W option for finer filtration at the cost of more frequent element service. The PT thread carries a MPa/psi gauge scale, and the reverse-flow valve is fitted per the K code. Spares are orderable as GAFR400-10 and GAL400-10. With max supply at 1.0 MPa, you have about 0.6 MPa of headroom above the 0.4 MPa top of the regulated band, so plan your inlet pressure accordingly.
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 GAFC400C10ALNK FAQ
This F.R.L. combination operates from 0.15 to 0.4 MPa (20-58 psi) with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. It has a 100 cc drain bowl and a 185 cc oil bowl, weighs 1810 g, and uses a 40 um element with a 3/8in port.
The N in the code after the port means no gauge is supplied. The gauge connection on the GAFC400 body is 1/4in, so you can add a gauge later if you need to read the set pressure. The reverse-flow valve is fitted per the K code, and the automatic drain clears condensate without manual intervention.
