Airtac GAFC Air Service Unit GAFC300C08ASN
The AirTAC Airtac GAFC Air Service Unit GAFC300C08ASN 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 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAFC Air Service Unit GAFC300C08ASN
This GAFC300C08ASN is an F.R.L. combination built as two pieces on a T-bracket: the filter and regulator share one body, and the lubricator is the second unit. Air enters the 1/4in port, gets filtered to 40 um and regulated to 0.15-0.9 MPa (20-130 psi), then oil mist is added downstream. The metal bowl holds 60 cc of condensate, while the oil bowl holds 98 cc; the whole assembly weighs 1020 g.
Because the filter and regulator are integrated, there is one less inter-unit joint to seal compared to a three-piece filter-regulator-lubricator train. The automatic drain clears condensate without an operator, which suits unattended lines. No gauge is supplied with this model, so the set pressure cannot be read without adding one to the 1/8in gauge connection.

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 GAFC300C08ASN Is Used
Precision machining fixtures
Feed a 1/4in line to a CNC fixture clamp with regulated 0.15-0.9 MPa air and metered lubrication for the clamp cylinder.
Assembly line actuators
Supply a multi-station assembly bench where each station has a single actuator needing clean, pressure-set, lubricated air.
Test rig air supply
Provide filtered and regulated air to a pneumatic test rig, with the automatic drain reducing maintenance on a wet supply line.
Is the Airtac GAFC Air Service Unit GAFC300C08ASN the Right Air-Prep Unit?
The GAFC300 body with a 1/4in port sits between the smaller GAFC200 (1/8in-1/4in, 590 g) and the larger GAFC400 (3/8in-1/2in, 1810 g). The catalogue flow curve for this body is plotted to 3500 L/min at 0.7 MPa inlet, useful for sizing relative to a neighbour. 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 is fitted, and the 40 um element is the standard grade. Replacement units are orderable separately as the GAFR300-08 filter & regulator and the GAL300-08 lubricator. Since the lubricator adds oil mist, choose a plain GAFR if the line must stay oil-free. 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 the supply pressure accordingly.
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 GAFC300C08ASN FAQ
The working pressure range is 0.15-0.9 MPa (20-130 psi). Max pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). Temperature range is -5 to 70 C. The drain bowl holds 60 cc and the oil bowl holds 98 cc. Recommended lubricant is ISO VG 32. The unit weighs 1020 g.
The N after the port code means no gauge is supplied. If you need to read the set pressure, you can add a gauge to the 1/8in gauge connection on the GAFC300 body. The port itself is 1/4in with PT threads.
