About the Airtac GAFC Air Service Unit GAFC300C08AS
This GAFC300C08AS is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a shared T-bracket with quick clamps. The 1/4in port size and 1020 g mass place it in the mid-range class, suitable for feeding a single machine station or a small bank of actuators.
Air enters the first body where the 40 um element removes solids and moisture, and the regulator sets pressure to 0.15-0.9 MPa (20-130 psi). The lubricator then adds a controlled oil mist downstream, so oil never travels back through the regulator seat. With a metal bowl and automatic drain, this unit suits lines where condensate must clear itself 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 GAFC300C08AS Is Used
CNC coolant valves
Feed a bank of solenoid valves on a CNC lathe that need regulated air at 0.6 MPa and a fine oil mist for slideway lubrication.
Assembly station air prep
Condition air for a bench-top press and its pneumatic clamps in a small assembly cell, where the 60 cc bowl handles a shift of condensate.
Packaging line actuators
Supply a carton erector's cylinders and grippers with filtered, regulated, lubricated air, with the automatic drain reducing maintenance on a busy line.
Is the Airtac GAFC Air Service Unit GAFC300C08AS the Right Air-Prep Unit?
The metal bowl (C code) is a build choice for this unit; the shared specification of 1.0 MPa max pressure and -5 to 70 C applies regardless of bowl material, so confirm it suits your environment. The automatic drain clears condensate continuously, which is decisive for unattended operation. A circular gauge is fitted, reading MPa/psi for the default PT thread. The 40 um element handles general shop air; choose the W option for 5 um filtration if you feed precision valves. Replacement internals are orderable as GAFR300-08 and GAL300-08. With a 1.0 MPa max supply, there is only about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range, so plan your inlet 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 GAFC300C08AS FAQ
The working pressure range is 0.15-0.9 MPa (20-130 psi). Maximum pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). Operating temperature 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 A code specifies an automatic drain, which expels condensate from the 60 cc bowl without manual intervention. This is ideal for installations where the unit is mounted out of reach or on lines with high moisture content, as it prevents water buildup from reaching downstream components.
