About the Airtac GAFC Air Service Unit GAFC400N10SK
This GAFC400N10SK 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. Air enters the 3/8" port, gets filtered and regulated in the first body, then oil mist is added by the lubricator as the final step, so oil never travels back through the regulator seat. The nylon bowl holds 100 cc of condensate, the oil bowl 185 cc, and the whole unit weighs 1810 g.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 40 um element filtering the air. A circular gauge is fitted, reading in MPa and psi for the PT thread. The reverse-flow (reflux) valve is included as a separate pneumatic symbol in the catalogue. With a 6000 L/min flow curve plotted at 0.7 MPa inlet, this size class suits medium-duty lines where a 3/8" port is the main air feed.

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 GAFC400N10SK Is Used
CNC spindle lubrication
Feed a 3/8" line to a CNC spindle air system where the 40 um element protects precision bearings and the lubricator meters oil to the spindle. The 185 cc oil bowl supports extended machining runs before refilling.
Assembly station air prep
Mount on a panel feeding pneumatic screwdrivers and small cylinders at an assembly station. The 100 cc condensate bowl with semi-auto drain handles moisture from a wet compressor line, while the 1810 g weight needs a solid frame mount.
Packaging line actuators
Supply a bank of 3/8"-ported actuators on a packaging line. The reverse-flow valve is fitted for ordering purposes, and the 6000 L/min envelope at 0.7 MPa inlet gives headroom for multiple cylinders cycling simultaneously.
Is the Airtac GAFC Air Service Unit GAFC400N10SK the Right Air-Prep Unit?
Choose the GAFC400N10SK when you need a 3/8" port F.R.L. set with a nylon bowl and a reverse-flow valve. The nylon bowl is a build choice - the catalogue gives no impact or chemical data, so confirm it suits your environment. The semi-auto drain dumps condensate when pressure drops, while the manual drain gives on-demand control; both are fitted. The 40 um element is the standard grade, and the circular gauge reads MPa/psi on the PT thread. If you need finer filtration, the 5 um W element is available, and the GAFR400-10 filter-regulator plus GAL400-10 lubricator are orderable separately as spares. For oil-free lines, omit the lubricator and choose a plain GAFR instead. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan inlet pressure near the maximum if you need the full regulated 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.

The drain bowl holds 100 cc, the oil bowl 185 cc, and the unit weighs 1810 g. Recommended lubricant is ISO VG 32 or equivalent. The element is 40 um and the gauge reads MPa/psi.
The K code specifies a reverse-flow (reflux) valve fitted to this GAFC400N10SK. The catalogue shows it as a separate pneumatic symbol, and its detailed function is covered on a dedicated page. For the ordering code, it is a distinct option that changes the pneumatic circuit representation.
