About the Airtac GAFC Air Service Unit GAFC300C08ASK
This AirTAC GAFC300C08ASK is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator is mounted on a T-bracket with quick clamps. With a 1/4in port and a 1020 g mass, it suits small to mid-size machines where panel space is limited but a full air prep train is needed.
The metal bowl holds 60 cc of condensate and the oil bowl 98 cc, so the service interval is set by how wet the line is. The standard pressure range is 0.15-0.9 MPa (20-130 psi), and the 40 um element handles general shop air. A circular gauge is fitted, reading MPa/psi for the default 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 GAFC300C08ASK Is Used
Precision jig clamping
Feed a single-acting clamp on a CNC fixture with clean, regulated air. The 1/4in port and 40 um element suit a small pneumatic circuit where consistent pressure matters.
Machine tool lubrication
Use the lubricator to add ISO VG 32 oil mist to a slide or spindle air line. The 98 cc oil bowl supports a shift of operation before refilling.
Bench assembly stations
Power a hand-held screwdriver or blow-off nozzle on a workbench. The 1020 g unit mounts on a frame or panel, with the automatic drain reducing daily maintenance.
Is the Airtac GAFC Air Service Unit GAFC300C08ASK the Right Air-Prep Unit?
Choose the GAFC300C08ASK when you need a 1/4in port with a metal bowl and an automatic drain. The metal bowl is a build choice; the specification is identical to PC or nylon, so confirm it suits your surroundings. The automatic drain clears condensate without an operator, which suits unattended lines. The reverse-flow (reflux) valve is fitted, shown as a separate symbol in the catalogue. The gauge reads MPa/psi, matching the PT thread. If the line must stay oil-free, omit the lubricator and choose a plain GAFR300-08 filter-regulator instead. Spares are GAFR300-08 and GAL300-08. With a 1.0 MPa max supply, there is about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan supply 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 GAFC300C08ASK FAQ
The pressure range is 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). Operating temperature is -5 to 70 C. The drain bowl holds 60 cc and the oil bowl 98 cc. Recommended lubricant is ISO VG 32. The unit weighs 1020 g.
The C code specifies a metal bowl, and the A code specifies an automatic drain. The automatic drain clears condensate without manual intervention, which is useful for unattended operation. The metal bowl is a material choice; the catalogue gives no specific performance data for it, so confirm it suits your environment.
