About the Airtac GAFC Air Service Unit GAFC400N10SWK
This AirTAC GAFC400N10SWK is an F.R.L. combination built from two units on one T-shape bracket: a filter-regulator body that cleans and sets the pressure, followed by a lubricator that adds a controlled oil mist. The 3/8in port and 1810 g mass place it in the mid-size class, suited for machine headers or multi-station lines where a single point of air preparation serves several actuators.
Air enters at up to 1.0 MPa (145 psi) and the standard regulator holds the working range from 0.15 to 0.9 MPa (20-130 psi). The 5 um element traps fine particles for sensitive valves, while the nylon bowl holds 100 cc of condensate and the oil bowl holds 185 cc, so the unit runs longer between services. The circular gauge reads in MPa/psi, and the reverse-flow valve is fitted as part of this build.

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 GAFC400N10SWK Is Used
Precision valve control
The 5 um element protects sensitive pneumatic valves on a CNC machine tool from fine abrasive dust, while the regulated 0.15-0.9 MPa range keeps actuation consistent.
Multi-station assembly line
Feed a small assembly station with multiple cylinders and grippers. The 100 cc condensate bowl and 185 cc oil bowl reduce maintenance stops on a line running two shifts.
Instrument air for test rigs
Supply clean, lubricated air to a leak-test fixture that cycles frequently. The 5 um filtration removes particles that could clog fine orifices in test instrumentation.
Is the Airtac GAFC Air Service Unit GAFC400N10SWK the Right Air-Prep Unit?
Choose the GAFC400 body when your line needs more capacity than the GAFC300's 3500 L/min envelope but less than the GAFC500's 7000 L/min curve; this model's plotted flow reaches 6000 L/min at 0.7 MPa inlet. 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, and the manual drain gives on-demand control. The 5 um element filters finer than the standard 40 um, but expect more frequent element changes. The PT thread carries an MPa/psi gauge scale. Spare parts 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 your inlet pressure carefully 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.
Airtac GAFC Air Service Unit GAFC400N10SWK FAQ
This F.R.L. combination operates from 0.15 to 0.9 MPa (20-130 psi) with a maximum supply pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. The drain bowl holds 100 cc, the oil bowl holds 185 cc, and the unit weighs 1810 g.
The K indicates a reverse-flow (reflux) valve is fitted to this GAFC400N10SWK. The catalogue shows this as a separate pneumatic symbol in the ordering code. The valve is part of the build, so the unit is ready for applications that need this feature.
