About the Airtac GAFC Air Service Unit GAFC400N10SNWK
This GAFC400N10SNWK 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) in the first body, then the lubricator adds a controlled oil mist downstream. The 5 um element traps finer particles than the standard 40 um grade, making it suitable for precision valves or instrument air.
The nylon bowl holds 100 cc of condensate, while the oil bowl holds 185 cc, so service intervals are driven by these capacities rather than by the element alone. Weighing 1810 g, this unit needs a proper panel or frame mount rather than support from the tubing. The catalogue flow curve is plotted to 6000 L/min at 0.7 MPa inlet, which serves as a sizing envelope rather than a rated capacity.

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 GAFC400N10SNWK Is Used
Precision Valve Control
Feed a bank of precision pneumatic valves on a CNC machine tool with 5 um filtered air, ensuring fine particles do not affect spool movement or seal life.
Assembly Line Actuators
Supply a multi-station assembly line where several actuators cycle rapidly, relying on the 185 cc oil bowl to maintain consistent lubrication over extended runs.
Instrument Air Supply
Provide clean, regulated air to sensitive instruments in a test lab, where the 5 um element prevents particulate contamination from affecting measurement accuracy.
Is the Airtac GAFC Air Service Unit GAFC400N10SNWK the Right Air-Prep Unit?
The GAFC400 body with a 3/8" port sits between the smaller GAFC300 (1/4"-1/2" ports, 1020 g) and the larger GAFC500 (3/4" port, 1910 g). The nylon bowl is a build choice, but the common specification of 1.0 MPa max pressure and -5 to 70 C applies regardless of material, so confirm it suits your surroundings. Both semi-auto and manual drains are fitted, allowing condensate to dump on pressure drop or on demand. The 5 um element requires more frequent service than the 40 um standard, so weigh filtration against maintenance. No gauge is supplied, but the 1/4" gauge connection allows adding one later. The PT thread carries a MPa/psi scale if a gauge is fitted. The reverse-flow (reflux) valve is included, shown as a separate pneumatic symbol in the catalogue. Spare parts are orderable as GAFR400-10 and GAL400-10. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan a supply near 1.0 MPa if you need maximum regulated pressure.
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 GAFC400N10SNWK FAQ
The working pressure range is 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). Operating temperature is -5 to 70 C, and the recommended lubricant is ISO VG 32. The drain bowl holds 100 cc and the oil bowl holds 185 cc, with a total weight of 1810 g. The unit uses a 5 um element and has no gauge fitted.
The N in the code after the port indicates no gauge is supplied. The GAFC400 body has a 1/4" gauge connection, so you can add a separate gauge if you need to read the set pressure. Without one, you cannot visually verify the regulated output, so plan to add a gauge for critical applications.
