About the Airtac GAFC Air Service Unit GAFC400N10LW
This AirTAC GAFC400N10LW is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator is mounted beside them on a T-bracket. With a 3/8in port and a 1810 g mass, it suits panel or frame mounting on medium-sized machines rather than support from the tubing alone. The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), and the 5 um element traps fine particles for sensitive equipment.
The nylon bowl holds 100 cc of condensate, while the separate oil bowl holds 185 cc, so service intervals are driven by how often these fill rather than by a fixed schedule. Air is filtered and set to pressure in the first body, then the lubricator adds a metered ISO VG 32 oil mist last, downstream of the regulator seat. A circular gauge is fitted, reading MPa and psi for the default PT thread.

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 GAFC400N10LW Is Used
Precision Assembly Stations
Feed a multi-spindle screwdriving station where the 5 um element protects fine metering valves and the lower-pressure range prevents over-force on delicate parts.
Medium-Duty Machine Tools
Supply a CNC lathe's door cylinder and coolant valve manifold, where the 185 cc oil bowl keeps a consistent mist over long shifts without frequent refills.
Carton Erectors
Run a case erector's glue applicator and folding rails, where the 100 cc condensate bowl and semi-auto drain handle moisture from a humid plant environment.
Is the Airtac GAFC Air Service Unit GAFC400N10LW the Right Air-Prep Unit?
The GAFC400 body with a 3/8in port sits between the smaller GAFC300 (1/4in-1/2in ports, 1020 g) and the larger GAFC500 (3/4in port, 1910 g). The catalogue flow curve for this body is plotted to 6000 L/min at 0.7 MPa inlet, roughly 70% above the GAFC300's 3500 L/min envelope, so it handles a multi-actuator station without stepping up in weight. The nylon bowl is a build choice; the shared specification of 1.0 MPa max pressure and -5 to 70 C does not change with material, so confirm it suits your surroundings. The semi-auto drain dumps condensate on each pressure drop, and the manual drain gives on-demand control. The 5 um element filters finer than the standard 40 um, at the cost of more frequent element service. The PT thread carries a circular gauge scaled in MPa/psi. If the line must stay oil-free, omit the lubricator and choose a plain GAFR400-10 filter-regulator instead; otherwise the spares are GAFR400-10 and GAL400-10. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of this lower-pressure range, so plan the inlet 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 GAFC400N10LW FAQ
This lower-pressure unit regulates from 0.15 to 0.4 MPa (20-58 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and must not freeze. The drain bowl holds 100 cc, the oil bowl holds 185 cc, and the unit weighs 1810 g. Use ISO VG 32 or equivalent oil in the lubricator.
The N before the port code specifies a nylon bowl. AirTAC offers PC, metal, and nylon bowls, all sharing the same 1.0 MPa max pressure and -5 to 70 C specification. The catalogue does not publish impact or chemical resistance data per material, so confirm the nylon bowl suits your specific environment before ordering.
