About the Airtac GAFC Air Service Unit GAFC400N10ASWK
The GAFC400N10ASWK is a two-piece F.R.L. combination: a filter and regulator sharing one body, paired with a lubricator on a T-bracket. Air enters the 3/8" port, gets filtered to 5 um, regulated to 0.15-0.9 MPa (20-130 psi), then oil mist is added downstream. The nylon bowl holds 100 cc of condensate, the oil bowl 185 cc, and the whole unit weighs 1810 g.
The 5 um element traps finer particles than the standard 40 um, suiting precision valves or instrument air, though it will need more frequent service. The automatic drain clears condensate without an operator, ideal for unattended lines. A circular gauge with MPa/psi scale is fitted, and the reverse-flow (reflux) valve is included as an ordering option.

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 GAFC400N10ASWK Is Used
Precision Valve Control
Feed a bank of 3/8" solenoid valves on an assembly station, where the 5 um element protects fine orifices from particle wear.
Machine Tool Lubrication
Supply a small CNC spindle or tool changer with filtered, regulated air and a metered oil mist for slideway lubrication.
Packaging Line Actuators
Run a carton erector's pneumatic cylinders, where the automatic drain handles condensate from a humid plant air supply.
Is the Airtac GAFC Air Service Unit GAFC400N10ASWK the Right Air-Prep Unit?
Choose this GAFC400 for 3/8" lines needing clean, regulated, lubricated air. The nylon bowl is a build choice - the common spec (1.0 MPa max, -5 to 70 C) applies to all materials, so confirm it suits your environment. The automatic drain suits wet or remote installations, while the 5 um element trades service frequency for finer filtration. The PT thread carries an MPa/psi gauge scale; the reflux valve is fitted per the K code. Spares are GAFR400-10 and GAL400-10, orderable separately. With a 1.0 MPa max supply, you have about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan supply pressure carefully if running near the ceiling.
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 GAFC400N10ASWK FAQ
This standard-type unit operates at 0.15-0.9 MPa (20-130 psi) with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. Temperature range is -5 to 70 C. The drain bowl holds 100 cc and the oil bowl 185 cc, with a total weight of 1810 g. Use ISO VG 32 oil in the lubricator.
The 5 um element catches far finer particles than the standard 40 um, which is better for precision equipment but means the element will load up faster. Plan more frequent element inspections or replacements compared to a standard unit, and keep a spare GAFR400-10 element on hand.
