About the Airtac GAFC Air Service Unit GAFC400N10ASNK
This AirTAC GAFC400N10ASNK is a two-piece F.R.L. combination. The first body combines a filter and a regulator, cleaning the air and setting its pressure. The second body is the lubricator, which adds a controlled oil mist downstream, so oil never travels back through the regulator seat.
The 3/8in port and 1810 g weight place it in the mid-range GAFC400 class. It regulates from 0.15 to 0.9 MPa (20-130 psi) with a 40 um element. The nylon bowl is specified by the N code, and the automatic drain clears condensate without an operator. No gauge is supplied, but the 1/4in gauge connection is ready for one.

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 GAFC400N10ASNK Is Used
Precision Fixture Clamping
Feed a multi-station clamping fixture on a CNC machining center. The 3/8in port and 40 um element protect precision valves, while the automatic drain keeps condensate out of the work zone.
Assembly Line Actuators
Power a series of guided actuators on an assembly line. The 1810 g unit mounts on a machine frame, and the lubricator meters oil to extend cylinder seal life.
Packaging Machine Air Prep
Supply a packaging machine's pick-and-place arm with filtered, regulated, and lubricated air. The 100 cc condensate bowl and 185 cc oil bowl reduce service frequency during long production runs.
Is the Airtac GAFC Air Service Unit GAFC400N10ASNK the Right Air-Prep Unit?
Choose the GAFC400N10ASNK when a 3/8in port and 1810 g mass suit your panel or frame. The nylon bowl is a build choice; the common specification of 1.0 MPa max and -5 to 70 C applies to all bowl materials, so confirm nylon suits your surroundings. The automatic drain handles wet lines without manual attention, and the reverse-flow valve is fitted as an ordering difference. The 40 um element is the standard grade; a 5 um W option traps finer particles but needs more frequent service. The PT thread carries a gauge scale in MPa/psi, though this model ships without a gauge. Spare parts are orderable as GAFR400-10 and GAL400-10. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan a supply near 1.0 MPa if you need the full regulated output.
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 GAFC400N10ASNK FAQ
The GAFC400N10ASNK operates from 0.15 to 0.9 MPa (20-130 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. It has a 100 cc drain bowl and a 185 cc oil bowl, weighs 1810 g, and uses ISO VG 32 lubricant. The element is 40 um.
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 gauge later if you need to read the set pressure. The PT thread option would use a gauge scale in MPa/psi.
