About the Airtac GAFC Air Service Unit GAFC400C10SNW
This GAFC400C10SNW is a two-piece F.R.L. combination: a filter-regulator body that cleans the air and sets its pressure, paired with a lubricator that adds a metered oil mist last. The 3/8in port and 1810 g mass place it in the mid-range size class, suited to feeding a few actuators or a small machine header from a single point.
The metal bowl holds 100 cc of condensate and the oil bowl 185 cc, so service intervals are generous for a unit this size. It regulates from 0.15 to 0.9 MPa (20-130 psi) and filters to 5 um, trapping finer particles than the standard 40 um element for downstream precision valves.

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 GAFC400C10SNW Is Used
Precision valve control
The 5 um element protects sensitive pilot valves and instrument air circuits on a small assembly station, where finer filtration prevents sticking.
Single machine header
Feed a compact machine header with 3/8in drops, supplying filtered and regulated air to a few cylinders or a small indexing table.
Semi-auto drain duty
For a line that sees regular pressure drops, the semi-auto drain clears condensate each cycle, reducing manual attention between shifts.
Is the Airtac GAFC Air Service Unit GAFC400C10SNW the Right Air-Prep Unit?
Choose this GAFC400C10SNW when you need a 3/8in port with a 5 um element and a metal bowl. The metal bowl is a build choice for the assembly area; the shared specification of 1.0 MPa max and -5 to 70 C does not change with material, so confirm it suits your surroundings. The semi-auto drain dumps condensate when pressure drops, and the manual drain gives on-demand control. No gauge is fitted, so the 1/4in gauge connection must be used if you want to read the set pressure. The PT thread carries an MPa/psi scale if a gauge is added. Spares are orderable as GAFR400-10 and GAL400-10. With a 1.0 MPa max supply, you have about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range, so plan the supply pressure accordingly.
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 GAFC400C10SNW FAQ
The GAFC400C10SNW 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. The drain bowl holds 100 cc, the oil bowl 185 cc, and the unit weighs 1810 g. Recommended lubricant is ISO VG 32.
The C code specifies a metal bowl, which is a build choice for the environment; the catalogue gives no performance difference between bowl materials. The N after the port means no gauge is supplied, so the 1/4in gauge connection is left for you to fit one if needed.
