The AirTAC Airtac GAFC Air Service Unit GAFC400C10SNK is a genuine two-piece F.R.L. combination — a GA-series filter & regulator and a lubricator pre-assembled on one T-shape bracket with quick mounting clamps. It has 3/8" ports, a 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).
This GAFC400C10SNK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a shared T-bracket. The 3/8" port size and 1810 g mass place it in the mid-range class, suited for feeding a multi-axis machine station or a small assembly line header.
The metal bowl holds 100 cc of condensate while the oil bowl holds 185 cc, so service intervals are longer than on smaller bodies. It operates from 0.15-0.9 MPa (20-130 psi) with a 40 um element, and the reverse-flow valve is fitted. No gauge is supplied, but the 1/4" gauge connection is ready for one if you need to read the set pressure.

Specifications follow the official AirTAC GAFC catalogue (pages 219-220). Air must not freeze in the unit. No gauge is supplied with this model — the gauge connection on a GAFC400 is 1/4" if you add one.

Constituent units, orderable separately as spares: GAFR400-10 filter & regulator, GAL400-10 lubricator — both share this body and port. A GAFC has two units, not three: the filter and the regulator are one body.
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.

Feeds filtered, regulated air to a CNC machine's coolant valve manifold, where the 3/8" port matches typical solenoid valve banks and the 185 cc oil bowl keeps the lubricator filled through long shifts.
Supplies a multi-station assembly line's pneumatic actuators and grippers, with the 100 cc condensate bowl reducing how often an operator must check the filter on a busy production floor.
Prepares air for a carton sealing machine's cylinders and sensors, where the metal bowl suits a plant environment and the 1810 g unit mounts securely on a machine frame.
Choose this GAFC400C10SNK when you need a 3/8" port with a metal bowl and the standard 0.15-0.9 MPa (20-130 psi) range. The semi-auto drain dumps condensate on pressure drop, while the manual drain gives on-demand control. The K code adds the reverse-flow valve, which the catalogue shows as a separate pneumatic symbol. Replacement units are GAFR400-10 and GAL400-10, both orderable separately. If your line must stay oil-free, omit the lubricator and pick a plain GAFR filter-regulator instead. With a 1.0 MPa max supply, you have about 0.1 MPa above the 0.9 MPa top of the range, so plan your inlet pressure accordingly.
Quick checklist
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.
This F.R.L. combination works with air, has a 3/8" port, and regulates from 0.15-0.9 MPa (20-130 psi). Maximum pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). It operates from -5 to 70 C and uses ISO VG 32 oil. The drain bowl holds 100 cc, the oil bowl 185 cc, and the unit weighs 1810 g.
The N in the code means no gauge is supplied with the unit. The GAFC400 body has a 1/4" gauge connection, so you can add a compatible gauge later if you need to monitor the outlet pressure. The PT thread on the connection uses an MPa/psi scale if you fit the standard AirTAC gauge.
