About the Airtac GAFC Air Service Unit GAFC300N15ALNWK
This AirTAC GAFC300N15ALNWK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. The 1/2in port size and 1020 g mass place it in the mid-range class, suitable for feeding a single machine station or a small multi-axis assembly cell.
Air enters the first body where the 5 um element removes fine particles and the regulator sets pressure to 0.15-0.4 MPa (20-58 psi). The lubricator then adds a metered oil mist downstream, so oil never passes back through the regulator seat. The nylon bowl is specified for this unit; the catalogue lists no material-specific performance differences, so confirm it suits your environment.

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 GAFC300N15ALNWK Is Used
Precision Assembly Fixture
Feed a pneumatic press or indexing table that needs regulated 0.15-0.4 MPa air. The 5 um element protects sensitive tooling from fine particulate, while the automatic drain keeps the bowl clear during long production runs.
Machine Tool Coolant Valve
Operate a coolant control valve on a CNC lathe where a lower regulated pressure prevents over-travel. The nylon bowl is specified for this build; confirm it suits the cutting-fluid atmosphere before installation.
Packaging Line Cylinder
Drive a single-acting cylinder on a carton-sealing station. The 1/2in port and 1020 g mass suit a fixed panel mount, and the automatic drain reduces maintenance on a line that runs multiple shifts.
Is the Airtac GAFC Air Service Unit GAFC300N15ALNWK the Right Air-Prep Unit?
The GAFC300 body with a 1/2in port offers a 60 cc condensate bowl and a 98 cc oil bowl, with the catalogue flow curve plotted to 3500 L/min at 0.7 MPa inlet. The automatic drain clears condensate without operator intervention, which suits unattended or continuously running equipment. The 5 um element traps finer particles than the standard 40 um grade, making it a better match for precision valves or instrument circuits, though it will need more frequent service. No gauge is supplied with this model; the 1/8" gauge connection is available if you add one later. The reverse-flow (reflux) valve is fitted, and the PT thread with MPa/psi scale is standard. The two units are orderable separately as GAFR300-15 and GAL300-15. For this lower-pressure type, the 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range.
Quick checklist
- ✓ Body size for your peak flow (1/2" 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 GAFR300-15 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300N15ALNWK FAQ
This lower-pressure unit 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). It is rated for -5 to 70 C and uses ISO VG 32 lubricant. The 60 cc drain bowl and 98 cc oil bowl are both nylon, and the complete assembly weighs 1020 g.
The N in the code after the port indicates no gauge is supplied with this unit. If you need to read the set pressure, the 1/8" gauge connection on the GAFC300 body accepts a standard AirTAC gauge. This keeps the initial cost lower when a panel-mounted gauge is already present in your system.
