About the Airtac GAFC Air Service Unit GAFC400C10AL
This AirTAC GAFC400C10AL is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. The 3/8in port and 1810 g mass place it in the mid-size class, suited to machine headers rather than single small actuators. It regulates in the lower-pressure band of 0.15-0.4 MPa (20-58 psi) and filters to 40 um.
The metal bowl is specified by the C code, and the common specification of 1.0 MPa max pressure and -5 to 70 C applies unchanged. The automatic drain clears condensate from the 100 cc bowl without operator attention, while the 185 cc oil bowl feeds the lubricator. A circular gauge is fitted, reading MPa and psi on the default PT thread scale.

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 GAFC400C10AL Is Used
Precision pressure setting
Set a precise 0.3 MPa for a delicate pneumatic clamping fixture on a CNC machine, where the lower-pressure regulator range gives fine control.
Wet utility line
Feed a washdown station's air tools where the automatic drain clears condensate from the 100 cc bowl without manual checks.
Low-pressure test bench
Supply a calibration bench that needs a stable 0.2-0.35 MPa air supply for testing sensitive pressure switches.
Is the Airtac GAFC Air Service Unit GAFC400C10AL the Right Air-Prep Unit?
Choose the GAFC400C10AL when your circuit needs a 3/8in port and a regulated ceiling of 0.4 MPa. The L type tops out at 0.4 MPa, so if the machine may ever require more pressure, select the standard S type instead. The metal bowl is a build choice; confirm it suits your surroundings, as the catalogue gives no material-specific ratings. The automatic drain suits unattended lines, and the 40 um element handles general workshop air. Spares are the GAFR400-10 filter-regulator and GAL400-10 lubricator, both orderable separately. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range.
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 GAFC400C10AL 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 has a 3/8in port, 40 um element, 100 cc drain bowl and 185 cc oil bowl. Temperature range is -5 to 70 C, recommended lubricant is ISO VG 32, and it weighs 1810 g.
The C code specifies a metal bowl. The catalogue does not publish impact, heat or chemical resistance data for bowl materials, so the choice is a build preference. The pressure and temperature ratings are identical across PC, metal and nylon bowls. Confirm the metal bowl suits your environment before ordering.
