About the Airtac GAFC Air Service Unit GAFC400N10L
This AirTAC GAFC400N10L is a two-piece F.R.L. combination: the first body houses the filter and regulator together, and the second body is the lubricator. They mount on a shared T-bracket with quick clamps, so the 3/8in port unit weighs 1810 g and needs a proper panel or frame mount, not support from the tubing.
The lower-pressure regulator is set for 0.15-0.4 MPa (20-58 psi), and the 40 um element cleans the air before the lubricator adds a metered oil mist last. The nylon bowl is named as a build choice, but the catalogue gives no impact or chemical data for it, so confirm it suits your surroundings. The circular gauge is fitted and reads in MPa and psi.

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 GAFC400N10L Is Used
Precision Pressure Set
Set a precise 0.3 MPa for a delicate pneumatic clamp on a CNC fixture, where the lower-pressure range gives finer adjustment than a standard regulator.
Assembly Line Lubrication
Feed a small assembly station's pneumatic screwdriver with filtered, regulated air and a consistent oil mist, keeping the tool running smoothly.
Test Rig Air Supply
Supply a laboratory test jig that requires a stable, low-pressure air source, with the 40 um element protecting sensitive test valves from particulates.
Is the Airtac GAFC Air Service Unit GAFC400N10L the Right Air-Prep Unit?
Choose the GAFC400 for a 3/8in port line that needs a 100 cc condensate bowl and a 185 cc oil bowl, giving a longer service interval than the GAFC300's 60 cc and 98 cc bowls. The L type tops out at 0.4 MPa, so if your machine may ever need more than that, pick the standard S type instead. The nylon bowl is a material choice, not a performance upgrade, and the semi-auto drain dumps on each pressure drop while the manual drain works on demand. The 40 um element is the standard grade, and the PT thread means the gauge scale is MPa/psi. The two units are orderable separately as the GAFR400-10 filter & regulator and the GAL400-10 lubricator. 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 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 GAFC400N10L FAQ
The GAFC400N10L operates at 0.15-0.4 MPa (20-58 psi), with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It has a 100 cc drain bowl and a 185 cc oil bowl, weighs 1810 g, and is rated for -5 to 70 C. The recommended lubricant is ISO VG 32.
The 'L' designates the lower-pressure type, which regulates from 0.15 to 0.4 MPa (20-58 psi). This is different from the standard 'S' type that goes up to 0.9 MPa. If your application might need more than 0.4 MPa, the 'L' type is not suitable.
