About the Airtac GAFC Air Service Unit GAFC400C10ASK
This AirTAC GAFC400C10ASK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a shared T-bracket with quick clamps. The 3/8in port and 1810 g mass place it in the mid-size class, where the 100 cc condensate bowl and 185 cc oil bowl mean fewer service visits than smaller bodies. Air is filtered and set to pressure in the first body, then the lubricator adds a metered oil mist last, so oil never travels back through the regulator seat.
It operates in the standard 0.15-0.9 MPa (20-130 psi) band with a 40 um element, and the metal bowl is specified by the C code. The automatic drain clears condensate without an operator, and the circular gauge reads in MPa/psi for the default PT thread. A reverse-flow (reflux) valve is fitted, shown as a separate symbol in the catalogue. Max pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and the working temperature range is -5 to 70 C.

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 GAFC400C10ASK Is Used
Precision valve actuation
Feed a bank of pneumatic valves on a CNC machining center, where the 40 um element and regulated 0.15-0.9 MPa output keep pilot air clean and consistent.
Assembly line automation
Supply a multi-station assembly fixture with filtered, regulated, lubricated air, with the automatic drain handling condensate from a humid plant line without manual attention.
Packaging machine air prep
Protect cylinders on a carton erector or case packer, where the 100 cc condensate bowl and 185 cc oil bowl reduce maintenance stops between shifts.
Is the Airtac GAFC Air Service Unit GAFC400C10ASK the Right Air-Prep Unit?
The GAFC400 body with its 3/8in port sits between the GAFC300 (1/4in-1/2in ports, 1020 g) and the GAFC500 (3/4in port, 1910 g). Its 100 cc drain bowl holds about 67% more condensate than the GAFC300's 60 cc, so it suits lines with moderate moisture loads. The metal bowl is a build choice for the specified environment, but the catalogue gives no material-specific temperature or impact data, so confirm it suits your surroundings. The automatic drain is fitted, which is decisive for unattended stations or wet supply lines. The standard pressure type covers 0.15-0.9 MPa (20-130 psi), and the 40 um element is the default grade. The circular gauge is fitted with an MPa/psi scale for the PT thread, and the reverse-flow valve is included. Replacement units are orderable separately as GAFR400-10 and GAL400-10. With a 1.0 MPa max supply, there is only about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range, so plan the supply pressure accordingly if you need the full 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.

It has a 100 cc condensate bowl and a 185 cc oil bowl, weighs 1810 g, and uses ISO VG 32 or equivalent lubricant. The element grade is 40 um, and the port size is 3/8in.
The K code specifies that a reverse-flow (reflux) valve is fitted to this GAFC400C10ASK. The catalogue draws this valve as a separate pneumatic symbol. It is an ordering difference from models without the K code, and the valve is included as part of the assembly.
