About the Airtac GAFC Air Service Unit GAFC300C10ALW
This GAFC300C10ALW is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. The 3/8in port and 1020 g mass place it in the mid-range class, sized for a machine station rather than a single small cylinder. The metal bowl holds 60 cc of condensate, while the oil bowl holds 98 cc, so the service interval is set by how often the line is wet.
The lower-pressure regulator tops out at 0.4 MPa (20-58 psi), which suits gentle clamping or air-bearing circuits. The 5 um element traps finer particles than the standard 40 um grade, protecting precision valves downstream. A circular gauge is fitted, reading MPa/psi for the PT thread. The automatic drain clears water without an operator, which matters on a line that runs unattended.

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 GAFC300C10ALW Is Used
Air bearing spindles
Feed a 3/8in line to an air-bearing spindle that needs a stable 0.3 MPa supply. The 5 um element keeps fine particles out of the bearing gap, and the lower-pressure regulator prevents over-pressurization.
Film tensioning rolls
Regulate the pneumatic brake on a film winder to 0.25 MPa for consistent tension. The automatic drain clears condensate from the 60 cc bowl during long packaging runs, and the metal bowl handles the factory floor.
Lab pneumatic circuits
Supply a lab test rig that uses a 0.2 MPa air cushion. The lower-pressure range gives fine adjustment below 0.4 MPa, and the 98 cc oil bowl keeps a small lubricator running for weeks between refills.
Is the Airtac GAFC Air Service Unit GAFC300C10ALW the Right Air-Prep Unit?
Choose this GAFC300C10ALW when the circuit needs a soft 0.15-0.4 MPa ceiling and fine filtration. The L type is the wrong part if the machine may ever need more than 0.4 MPa, since the regulator cannot go higher. The metal bowl is a build choice, not a performance upgrade, and the shared specification of 1.0 MPa max and -5 to 70 C applies to all bowl materials, so confirm the metal suits your environment. The automatic drain removes condensate by itself, and the 5 um element suits instrument air but will need more frequent service than a 40 um grade. Spares are orderable as the GAFR300-10 filter & regulator and the GAL300-10 lubricator. With a 1.0 MPa max supply, there is about 0.6 MPa of headroom above the 0.4 MPa top of the range, so plan the inlet pressure accordingly.
Quick checklist
- ✓ Body size for your peak flow (3/8" 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 GAFR300-10 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300C10ALW FAQ
This F.R.L. combination works with air only, filtering to 5 um. The lower-pressure regulator range is 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). It operates from -5 to 70 C and must not freeze. The drain bowl holds 60 cc, the oil bowl 98 cc, and the unit weighs 1020 g. Use ISO VG 32 oil in the lubricator.
The C code specifies a metal bowl, which is a build choice for the installation environment. The A code means the drain is automatic, so it clears condensate from the 60 cc bowl without an operator. The catalogue gives no performance difference between bowl materials, so confirm the metal suits your surroundings. The automatic drain is useful for lines that run unattended or in wet conditions.
