Airtac GAFC Air Service Unit GAFC300N08ASW
The AirTAC Airtac GAFC Air Service Unit GAFC300N08ASW is a genuine two-piece F.R.L. combination — a GA-series filter & regulator and a lubricator pre-assembled on one T-shape bracket with quick mounting clamps. It has 1/4" ports, a 5 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAFC Air Service Unit GAFC300N08ASW
This AirTAC GAFC300N08ASW is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator mounts on a T-bracket beside it. With a 1/4in port, it handles the 0.15-0.9 MPa (20-130 psi) range and uses a 5 um element to catch fine particles before they reach sensitive valves.
The nylon bowl holds 60 cc of condensate while the oil bowl holds 98 cc, and the automatic drain clears water without an operator. The circular gauge reads in MPa/psi, and the whole unit weighs 1020 g, so it needs a proper panel mount rather than tubing support.

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 GAFC300N08ASW Is Used
Precision Valve Control
The 5 um element protects small solenoid valves on a pick-and-place arm from fine abrasive dust, while the regulator holds the set pressure for consistent actuator speed.
Packaging Line Feed
On a carton erector with a 1/4in air circuit, this unit filters and lubricates the cylinders that drive folding rails, with the automatic drain handling condensate from humid plant air.
Machine Tool Lubrication
For a small drill press needing clean, regulated air and a metered oil mist for its pneumatic feed cylinder, this combination delivers both functions in a compact two-piece footprint.
Is the Airtac GAFC Air Service Unit GAFC300N08ASW the Right Air-Prep Unit?
Choose the GAFC300N08ASW when you need 1/4in ports with the finer 5 um element and an automatic drain for unattended lines. The nylon bowl is a build choice, not a performance upgrade - the 1.0 MPa max and -5 to 70 C rating stay the same across materials, so confirm it suits your environment. The PT thread carries a gauge with an MPa/psi scale, and you can order the filter-regulator and lubricator separately as GAFR300-08 and GAL300-08 if a bowl or element needs replacement.
With a 1.0 MPa max supply, you have about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range, so plan your inlet pressure carefully if you need the full output.
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 GAFC300N08ASW FAQ
It operates at 0.15-0.9 MPa (20-130 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 it uses ISO VG 32 lubricant. The drain bowl holds 60 cc, the oil bowl holds 98 cc, and the unit weighs 1020 g.
The W code specifies a 5 um element, which traps finer particles than the standard 40 um grade. This suits precision valves or instrument air circuits, but the finer element will load up faster and need more frequent service, so factor that into your maintenance schedule.
