About the Airtac GAFC Air Service Unit GAFC400N10LNK
This GAFC400N10LNK is a two-piece F.R.L. combination: a filter-regulator body handles filtration and pressure control, then a separate lubricator body adds a metered oil mist downstream. The 3/8in port and 1810 g mass place it in the mid-size class, suited for a machine header or a small multi-station line rather than a single actuator.
The lower-pressure regulator is set for 0.15-0.4 MPa (20-58 psi), with a 40 um element and a nylon bowl. The 100 cc condensate bowl and 185 cc oil bowl set the service rhythm, and since no gauge is fitted, the 1/4in gauge connection is left for a later add-on. The reverse-flow valve is included as an ordering option.

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 GAFC400N10LNK Is Used
Precision Fixture Clamping
Feed a multi-point clamping fixture on a CNC machine where the lower pressure range protects delicate workpieces from over-clamping, and the 100 cc bowl handles condensate from a busy shift.
Assembly Line Lubrication
Supply a metered oil mist to a bank of pneumatic screwdrivers on an assembly line, where the 185 cc oil bowl extends time between refills and the semi-auto drain clears water on each pressure drop.
Test Bench Air Supply
Power a pneumatic test bench for valve actuation cycles, where the 0.15-0.4 MPa range suits low-force testing and the 6000 L/min envelope at 0.7 MPa inlet supports multiple test stations.
Is the Airtac GAFC Air Service Unit GAFC400N10LNK the Right Air-Prep Unit?
Choose the GAFC400 body when a 3/8in port with a 6000 L/min plotted flow envelope at 0.7 MPa inlet fits the line, and the 1810 g weight suits a panel or frame mount. The nylon bowl is a build choice; confirm it suits the environment, as the common specification of 1.0 MPa max and -5 to 70 C applies across materials. The semi-auto drain dumps on pressure drop, with a manual backup, and the 40 um element is the standard grade. The L type tops out at 0.4 MPa, so if the machine may need more pressure, this is the wrong part. No gauge is supplied, so plan to read pressure via the 1/4in connection. The PT thread carries a MPa/psi scale if a gauge is added. Spares are orderable as GAFR400-10 and GAL400-10. Max supply of 1.0 MPa leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan the 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 GAFC400N10LNK 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). Temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. It has a 100 cc drain bowl, 185 cc oil bowl, and weighs 1810 g. The 40 um element filters the air, and the semi-auto drain clears condensate automatically on pressure drop.
The N after the port code means no gauge is supplied with this unit. The gauge connection on the GAFC400 body is 1/4in, so you can add a circular gauge later if needed. The PT thread on the connection uses an MPa/psi scale, which you should match to what your operators read.
