About the Airtac GAFC Air Service Unit GAFC400N10LNW
This AirTAC GAFC400N10LNW is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator is mounted on the same T-bracket. Air is cleaned and set to pressure in the first unit, then a metered oil mist is added last, so oil never travels back through the regulator seat. With a 3/8" port and 1810 g mass, it suits mid-size machine headers where a compact footprint matters.
The lower-pressure regulator is set for 0.15-0.4 MPa (20-58 psi), and the 5 um element traps fine particles for sensitive valves. The nylon bowl holds 100 cc of condensate while the oil bowl holds 185 cc, and the unit has no gauge fitted - the 1/4" gauge connection is there if you add one. It operates from -5 to 70 C and must not freeze.

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 GAFC400N10LNW Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging line where the 5 um element protects fine internal passages and the lower 0.4 MPa range keeps actuation gentle.
Mid-size machine header
Mount on a 3/8" header supplying a multi-station assembly machine, where the 1810 g unit needs a proper panel mount and the 185 cc oil bowl supports longer runs between refills.
Instrument air branch
Use on a test bench feeding air tools or gauges that require clean, regulated air at modest pressure, with the semi-auto drain clearing condensate each time the supply cycles.
Is the Airtac GAFC Air Service Unit GAFC400N10LNW the Right Air-Prep Unit?
Choose the GAFC400 body for 3/8" porting with a 6000 L/min flow curve at 0.7 MPa inlet, a step up from the GAFC300's 3500 L/min envelope. The nylon bowl is a build choice - the 1.0 MPa max and -5 to 70 C rating are identical across PC, metal, and nylon, so confirm the material suits your environment. This model has the semi-auto drain that dumps on pressure drop plus a manual drain for on-demand use, and the 5 um element means more frequent service than the standard 40 um grade.
The L type tops out at 0.4 MPa, so if your machine may ever need more pressure, this is the wrong part. No gauge is supplied, but the 1/4" connection accepts one later. The two units are orderable separately as GAFR400-10 and GAL400-10. With a 1.0 MPa max supply, you have about 0.6 MPa above the 0.4 MPa top of the range, so plan your inlet pressure carefully.
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 GAFC400N10LNW FAQ
This F.R.L. combination operates at 0.15-0.4 MPa (20-58 psi) with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. The temperature range is -5 to 70 C, and it uses ISO VG 32 oil. The drain bowl holds 100 cc, the oil bowl holds 185 cc, and the unit weighs 1810 g. The 5 um filter element is fitted, and the gauge connection is 1/4".
The N after the port code means no gauge is supplied with this unit. The 1/4" gauge connection is still there, so you can add a circular gauge later if you need to read the set pressure. Without one, you cannot verify the outlet pressure visually, so plan to add a gauge for applications where the 0.15-0.4 MPa setting must be confirmed.
