About the Airtac GAFC Air Service Unit GAFC300N15ALW
This AirTAC GAFC300N15ALW 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. Air is cleaned and set to pressure in the first body, then the lubricator adds a metered oil mist last, so the regulator seat never sees oil. With a 1/2in port and 1020 g mass, it suits mid-size machine circuits where a panel or frame mount is expected.
The lower-pressure L type regulates from 0.15 to 0.4 MPa (20-58 psi), and the 5 um element traps finer particles than the standard 40 um grade for sensitive valves. The nylon bowl holds 60 cc of condensate and the oil bowl 98 cc, while the automatic drain clears water without an operator. A circular gauge is fitted, reading in MPa and psi for the PT thread, and the unit is rated -5 to 70 C with ISO VG 32 oil recommended.

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 GAFC300N15ALW Is Used
Precision valve control
Feeds a bank of 1/2in solenoid valves on a packaging machine, where the 5 um element keeps fine particles out of valve pilots and the lower pressure range prevents over-stroking small actuators.
Wet-line condensate duty
Serves a parts-washing station with high humidity in the air supply, where the automatic drain clears water from the 60 cc bowl without an operator and the nylon bowl resists the damp environment.
Low-pressure test rig
Supplies a 1/2in test fixture that must stay below 0.4 MPa, using the L-type regulator to hold a stable low setpoint while the lubricator oils a reciprocating cylinder.
Is the Airtac GAFC Air Service Unit GAFC300N15ALW the Right Air-Prep Unit?
Choose this GAFC300N15ALW when your line needs 1/2in ports and a regulated ceiling of 0.4 MPa. The nylon bowl is a build choice, not a performance upgrade, so confirm it suits your environment; the automatic drain is the right call for unattended or wet lines. The 5 um element protects precision equipment but will need service sooner than a 40 um grade. Spares are orderable as the GAFR300-15 filter-regulator and the GAL300-15 lubricator, both matching this body and port. If the line must stay oil-free, omit the lubricator and choose a plain GAFR filter-regulator instead. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom 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 GAFC300N15ALW FAQ
The GAFC300N15ALW operates from 0.15 to 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, uses ISO VG 32 lubricant, has a 60 cc drain bowl and 98 cc oil bowl, and weighs 1020 g. The 5 um element and automatic drain are fitted, and the PT thread carries a circular gauge reading MPa and psi.
The L type is designed for applications that need a lower regulated pressure band, topping out at 0.4 MPa (58 psi) instead of the standard 0.9 MPa. If your machine may ever require more than 0.4 MPa at the actuator, this is the wrong part, and you should select the standard S type instead. The 1.0 MPa max supply still applies, but the regulator cannot be set above 0.4 MPa.
