About the Airtac GAFC Air Service Unit GAFC400N10ALWK
This AirTAC GAFC400N10ALWK is a two-piece F.R.L. combination: a filter and regulator share one body, then a lubricator adds oil mist downstream. With a 3/8in port and 5 um element, it cleans and meters air for precision pneumatic circuits while the automatic drain handles condensate.
The lower-pressure regulator tops out at 0.4 MPa (20-58 psi), and the nylon bowl holds 100 cc of condensate while the oil bowl holds 185 cc. At 1810 g, this unit suits a panel or frame mount rather than tubing support, and the circular gauge reads in MPa/psi.

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 GAFC400N10ALWK Is Used
Precision valve control
Feed a 5 um-filtered, regulated air supply to a bank of precision solenoid valves on a pick-and-place machine, where lower pressure protects delicate actuator seals.
Unattended assembly line
Mount on a multi-station assembly line where the automatic drain clears condensate without daily checks, and the 185 cc oil bowl keeps lubricators running between shifts.
Instrument air bench
Use in a test bench for pneumatic gauges or sensors, where the 0.4 MPa ceiling and 5 um element deliver clean, stable air for calibration work.
Is the Airtac GAFC Air Service Unit GAFC400N10ALWK the Right Air-Prep Unit?
For a GAFC400N10ALWK, the nylon bowl is a build choice for the environment, though the 1.0 MPa max and -5 to 70 C rating stay the same across materials. The automatic drain clears water without an operator, ideal for unattended lines, and the 5 um element traps finer particles than the standard 40 um, at the cost of more frequent service. The PT thread pairs with an MPa/psi gauge scale, and the reverse-flow valve is fitted as an ordering difference. If the line must stay oil-free, omit the lubricator and choose a plain GAFR400-10 filter-regulator instead; spares for this unit are GAFR400-10 and GAL400-10. With a 1.0 MPa max supply, you have about 0.6 MPa above the 0.4 MPa top of the range, so plan the inlet pressure carefully.
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 GAFC400N10ALWK FAQ
The GAFC400N10ALWK 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 in -5 to 70 C temperatures, uses ISO VG 32 lubricant, has a 100 cc drain bowl and 185 cc oil bowl, and weighs 1810 g.
The N before the port code specifies a nylon bowl, a material choice for the build. The K at the end means a reverse-flow valve is fitted, which the catalogue shows as a separate pneumatic symbol. The bowl material does not change the 1.0 MPa max pressure or temperature rating.
