About the Airtac GAFC Air Service Unit GAFC300N10ALW
This AirTAC GAFC300N10ALW is a two-piece F.R.L. combination: a filter-regulator body paired with a separate lubricator, mounted on a shared T-bracket with quick clamps. The 3/8in port size and 1020 g mass place it in the mid-range GAFC300 class, suited for a single machine station or a small pneumatic circuit.
Air enters the first body where the 5 um element traps fine particles and the lower-pressure regulator sets output between 0.15-0.4 MPa (20-58 psi). The lubricator then adds a metered ISO VG 32 oil mist downstream, so oil never travels back through the regulator seat. The nylon bowl holds 60 cc of condensate while the oil bowl holds 98 cc, and the automatic drain clears water without an operator.

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 GAFC300N10ALW Is Used
Precision Assembly Stations
Feed a compact pneumatic press or a precision tightening tool on an assembly bench, where the 5 um element protects sensitive valves and the lower pressure range suits delicate operations.
Laboratory Air Supply
Supply filtered, regulated air to a lab fixture or test jig that operates below 0.4 MPa, where the automatic drain keeps condensate out of the instrument air without daily attention.
Single-Actuator Machine
Run a single air cylinder or a small indexing mechanism on a packaging line, where the 3/8in port matches short runs and the 1020 g unit mounts easily on a machine frame.
Is the Airtac GAFC Air Service Unit GAFC300N10ALW the Right Air-Prep Unit?
The GAFC300N10ALW combines a nylon bowl, automatic drain, lower-pressure regulation, and a 5 um element on a 3/8in port. The L-type regulator tops out at 0.4 MPa (20-58 psi), so if your machine may ever need more than that, step to the standard S type instead. The nylon bowl is a build choice; the shared specification of 1.0 MPa max and -5 to 70 C applies equally to PC and metal bowls, so confirm the material suits your environment. The circular gauge reads in MPa/psi for the default PT thread, and the 5 um element catches finer particles than the standard 40 um but will need more frequent service. For oil-free lines, omit the lubricator and choose a plain GAFR300-10 filter-regulator. Spare parts are orderable separately as GAFR300-10 and GAL300-10. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of this unit's regulated range.
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 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1020 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 GAFR300-10 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300N10ALW FAQ
This F.R.L. combination operates at 0.15-0.4 MPa (20-58 psi) with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. The drain bowl holds 60 cc, the oil bowl holds 98 cc, and the unit weighs 1020 g. The 5 um element and automatic drain are fitted, and the circular gauge reads in MPa/psi.
The L in the code specifies the lower-pressure regulator type, which tops out at 0.4 MPa (20-58 psi) instead of the standard 0.9 MPa. This suits applications that never need higher pressure, such as delicate gripping or light clamping. If your process may require more pressure later, the standard S type would be the safer choice.
