About the Airtac GAFC Air Service Unit GAFC30008ALW
This AirTAC GAFC30008ALW is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a T-bracket with quick clamps. The 1/4in port size and 1020 g mass place it in the mid-range GAFC300 class, suitable for a single machine station or a small pneumatic circuit. The 5 um element traps finer particles than the standard 40 um grade, protecting precision valves and instruments downstream.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a max supply of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The automatic drain clears condensate from the 60 cc bowl without operator attention, while the 98 cc oil bowl feeds the lubricator with ISO VG 32 oil. The circular gauge is fitted, reading MPa and psi on the PT thread scale.

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 GAFC30008ALW Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a small assembly machine, where the 5 um element protects fine internal passages and the 0.4 MPa ceiling prevents over-pressurizing sensitive actuators.
Single-station automation
Supply a dedicated work cell with one or two pneumatic cylinders, using the 1/4in port and 1020 g body for a compact, panel-mounted air prep point.
Instrument air bench
Set up a test bench for pneumatic instruments that need clean, regulated air below 0.4 MPa, with the automatic drain keeping the 60 cc bowl clear during extended runs.
Is the Airtac GAFC Air Service Unit GAFC30008ALW the Right Air-Prep Unit?
Choose the GAFC30008ALW when your line needs fine filtration and a regulated pressure ceiling of 0.4 MPa. The 5 um element suits sensitive equipment but requires more frequent service than a 40 um grade. The automatic drain is ideal for wet or unattended lines, removing condensate from the 60 cc bowl automatically. The PC bowl is the standard build; confirm it suits your environment, as the catalogue gives no material-specific ratings. The circular gauge reads MPa and psi, matching the PT thread. For oil-free air, omit the lubricator and select a plain GAFR300-08 filter-regulator instead. Spare parts are orderable separately as GAFR300-08 and GAL300-08. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan the 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 GAFC30008ALW FAQ
The GAFC30008ALW 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). Temperature range is -5 to 70 C. It has a 60 cc drain bowl and a 98 cc oil bowl, weighs 1020 g, and uses ISO VG 32 lubricant. The 5 um element and automatic drain are fitted.
The L type code limits regulation to 0.15-0.4 MPa (20-58 psi), which is about 44% of the standard 0.9 MPa ceiling. This suits applications that must never exceed 0.4 MPa, such as delicate instrumentation. If your machine may need higher pressure later, the standard S type is the safer choice.
