About the Airtac GAFC Air Service Unit GAFC400C10ALK
This AirTAC GAFC400C10ALK 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 feeding a single machine station or a short distribution header. The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), and the 40 um element handles standard shop air.
The metal bowl is specified by the C code, and the automatic drain clears condensate without operator attention. A circular gauge is fitted, reading MPa/psi for the default PT thread. The reverse-flow (reflux) valve is fitted as an ordering difference. The 100 cc condensate bowl and 185 cc oil bowl set the service interval, and the lubricator is meant to carry ISO VG 32 oil.

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 GAFC400C10ALK Is Used
Precision Fixture Clamping
Feed a 3/8in line to a pneumatic fixture that clamps parts for a drilling operation. The lower-pressure range keeps clamping force gentle, and the automatic drain keeps condensate out of the work zone.
Single-Station Assembly Bench
Supply a bench-mounted actuator that pushes components into a press. The 100 cc condensate bowl and 185 cc oil bowl let the unit run a full shift before service, and the gauge lets the operator verify the set pressure.
Low-Pressure Test Rig
Power a test rig that checks seals at regulated pressures below 0.4 MPa. The 40 um element protects the test valve, and the metal bowl suits a shop environment where a clear bowl might be a concern.
Is the Airtac GAFC Air Service Unit GAFC400C10ALK the Right Air-Prep Unit?
Choose the GAFC400 body when a 3/8in port and a 1810 g unit fit your panel layout; the 100 cc drain bowl and 185 cc oil bowl reduce how often someone must attend the unit. The L type tops out at 0.4 MPa (20-58 psi), so if the machine may ever need more pressure, select a standard S type instead. The metal bowl is a build choice, and the automatic drain suits wet or unattended lines. The 40 um element is the standard grade, and the fitted gauge reads MPa/psi on the PT thread. Spare parts are orderable as GAFR400-10 and GAL400-10. A 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 GAFC400C10ALK FAQ
The GAFC400C10ALK operates from 0.15 to 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. The drain bowl holds 100 cc and the oil bowl holds 185 cc, with a total weight of 1810 g.
The C code specifies a metal bowl, a build choice for the unit's surroundings. The A code specifies an automatic drain, which clears condensate without an operator, making it suitable for unattended or wet lines. The gauge is fitted and reads in MPa/psi on the PT thread.
