About the Airtac GAFC Air Service Unit GAFC300C08ALWK
This AirTAC GAFC300C08ALWK is a two-piece F.R.L. combination: the filter and regulator share one metal-bowl body, and the lubricator is mounted on the same T-bracket. With a 1/4in port and 5 um element, it cleans and meters oil mist for a compact pneumatic circuit.
The lower-pressure regulator is set for 0.15-0.4 MPa (20-58 psi), and the 60 cc condensate bowl plus 98 cc oil bowl define the service rhythm. The automatic drain clears water without an operator, and the fitted circular gauge reads in MPa/psi for the 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 GAFC300C08ALWK Is Used
Precision assembly fixtures
Feed a 1/4in line to a benchtop press or clamping fixture where a 5 um element protects fine metering valves and the lower pressure range prevents over-force on delicate parts.
Laboratory air benches
Supply a lab workstation with filtered, regulated air at 0.15-0.4 MPa for pneumatic actuators on test rigs, where the automatic drain keeps condensate out of sensitive instruments.
Maintenance shop air tools
Run a small parts washer or blow-off station from a 1/4in drop, using the 5 um element to keep tool internals clean and the metal bowl for a shop-floor environment.
Is the Airtac GAFC Air Service Unit GAFC300C08ALWK the Right Air-Prep Unit?
The GAFC300 body suits 1/4in lines and weighs 1020 g, with the catalogue flow curve plotted to 3500 L/min at 0.7 MPa inlet. The metal bowl is a build choice; the shared specification of 1.0 MPa max and -5 to 70 C does not change with material, so confirm it suits your surroundings. The automatic drain handles wet lines, while the 5 um element traps finer particles than the standard 40 um but needs more frequent service. The reverse-flow valve is fitted per the K code. Spares are orderable as GAFR300-08 and GAL300-08. Since this is the lower-pressure type, it tops out at 0.4 MPa; the 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range.
Quick checklist
- ✓ Body size for your peak flow (1/4" 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 GAFR300-08 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300C08ALWK FAQ
This F.R.L. combination operates at 0.15-0.4 MPa (20-58 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. It has a 60 cc drain bowl and a 98 cc oil bowl, and the complete unit weighs 1020 g.
The C code specifies a metal bowl, which is a build choice for the surrounding environment; the catalogue does not rate one material as stronger than another. The W code means a 5 um element is fitted, which traps finer particles than the standard 40 um for cleaner air to sensitive components, though it will need more frequent replacement.
