About the Airtac GAFC Air Service Unit GAFC40010ALN
This AirTAC GAFC40010ALN is a two-piece F.R.L. combination: a filter-regulator body handles filtration and pressure setting, then a separate lubricator adds a metered oil mist downstream. The 3/8in port and 1810 g mass put it in the mid-size class, suited to feeding a multi-axis machine or a small production line. Its lower-pressure regulator is set for 0.15-0.4 MPa (20-58 psi), with a 40 um element as standard.
The automatic drain clears condensate from the 100 cc bowl without operator attention, while the 185 cc oil bowl keeps the lubricator running between refills. No gauge is supplied with this model, so the set pressure cannot be read without adding one to the 1/4in gauge connection. The PC bowl material is the standard build; confirm it suits your environment, as the catalogue gives no material-specific ratings.

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 GAFC40010ALN Is Used
Precision Jig Fixtures
Feed a custom jig or fixture that requires clean, regulated air at a consistent lower pressure, such as a clamping station on a CNC workbench.
Light Assembly Conveyors
Supply a short conveyor section with lubricated air for pneumatic stops or guides, where the 3/8in port matches typical valve manifolds.
Packaging Line Cylinders
Operate small packaging machine cylinders that cycle frequently, benefiting from the automatic drain to minimize downtime on a busy line.
Is the Airtac GAFC Air Service Unit GAFC40010ALN the Right Air-Prep Unit?
Choose the GAFC400 body when your line needs the 3/8in port and the 100 cc drain bowl capacity, stepping down to a GAFC300 (60 cc drain bowl) for lighter duty or up to a GAFC500 (108 cc drain bowl) for a 3/4in port. The A code specifies an automatic drain, which clears water without an operator - useful for unattended shifts or wet supply lines. The L type limits regulation to 0.15-0.4 MPa (20-58 psi), so confirm your actuators never need more than 0.4 MPa; if they might, the S type (0.15-0.9 MPa) is the safer choice. The N after the port means no gauge is fitted, but the 1/4in connection is ready for one. The PT thread suits standard pipe installations. For spares, order the GAFR400-10 filter-regulator and GAL400-10 lubricator separately. Note the 1.0 MPa max supply leaves 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 GAFC40010ALN FAQ
This F.R.L. combination operates on air with a lower pressure range of 0.15-0.4 MPa (20-58 psi). Maximum pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). It works in temperatures from -5 to 70 C and should not freeze. The unit has a 100 cc drain bowl and a 185 cc oil bowl, weighs 1810 g, and uses ISO VG 32 or equivalent lubricant.
The 'N' in the code means no gauge is supplied. The GAFC400 body has a 1/4in gauge connection, so you can add a compatible pressure gauge to monitor the set pressure. Without one, you cannot read the regulated output directly, which is important for applications needing a precise 0.15-0.4 MPa setting.
