About the Airtac GAFC Air Service Unit GAFC400C10SWK
The GAFC400C10SWK 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 to 0.15-0.9 MPa (20-130 psi), then the lubricator adds a controlled oil mist downstream. The metal bowl holds 100 cc of condensate, while the oil bowl holds 185 cc, and the whole unit weighs 1810 g.
The 5 um element traps finer particles than the standard 40 um grade, suiting precision valves or instrument air. A circular gauge is fitted, reading in MPa/psi for the PT thread. The reverse-flow (reflux) valve is included, shown as a separate symbol in the catalogue. With a 6000 L/min flow curve plotted at 0.7 MPa inlet, this size class suits medium-duty machine headers.

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 GAFC400C10SWK Is Used
CNC Coolant Valves
Feed a 3/8" line to CNC coolant solenoid valves, where the 5 um element keeps fine particles from jamming spool movement.
Assembly Line Manifolds
Supply a multi-station assembly manifold with regulated air, using the 185 cc oil bowl to maintain lubrication across several actuators.
Test Bench Air Supply
Provide clean, regulated air to a pneumatic test bench where the metal bowl resists accidental impacts and the gauge lets operators verify setpoints.
Is the Airtac GAFC Air Service Unit GAFC400C10SWK the Right Air-Prep Unit?
Choose the GAFC400C10SWK when you need a 3/8" port with a 5 um element and a metal bowl. The metal bowl is a build choice, not a performance upgrade - the 1.0 MPa max and -5 to 70 C range are identical across materials, so confirm it suits your environment. The semi-auto drain dumps on pressure drop, with a manual override for on-demand use. The fitted gauge reads MPa/psi, matching the PT thread. For spares, order the GAFR400-10 filter-regulator and GAL400-10 lubricator separately. If your line must stay oil-free, skip 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 your inlet 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 GAFC400C10SWK FAQ
The GAFC400C10SWK operates at 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It works in -5 to 70 C temperatures, uses ISO VG 32 oil, has a 100 cc drain bowl and 185 cc oil bowl, and weighs 1810 g. The 5 um element filters air before the lubricator adds oil mist.
The C code specifies a metal bowl, which is a build choice for environments where you prefer not to use plastic. The catalogue lists no performance difference - the pressure rating and temperature range are the same as PC or nylon bowls. Confirm the material suits your specific surroundings before ordering.
