About the Airtac GAFC Air Service Unit GAFC300N15ALNK
This AirTAC GAFC300N15ALNK is a two-piece F.R.L. combination: a filter and regulator share one body, and a lubricator is mounted downstream on a T-bracket with quick clamps. Air is cleaned and set to pressure in the first unit, then a metered oil mist is added last, so oil never travels back through the regulator seat. The 1/2in port and 1020 g mass place it in the mid-size class, suited for a machine header feeding several actuators.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 40 um element and an automatic drain that clears condensate from the 60 cc bowl without an operator. The nylon bowl is specified by the N code, and the catalogue's shared specification of 1.0 MPa max and -5 to 70 C applies regardless of bowl material. No gauge is supplied, so the set pressure cannot be read without adding one to the 1/8in gauge connection.

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 GAFC300N15ALNK Is Used
Precision pressure setting
Set a precise 0.3 MPa for a delicate pneumatic clamping fixture on a CNC machine, where the lower-pressure range gives finer adjustment resolution than a standard regulator.
Unattended condensate removal
Feed a multi-station assembly line with the automatic drain clearing water from the 60 cc bowl continuously, reducing maintenance rounds in a lightly staffed shift.
Lubricated tooling air
Supply a pneumatic screwdriver or grinder with filtered, regulated air and a controlled oil mist from the 98 cc oil bowl, keeping the tool's internal parts lubricated.
Is the Airtac GAFC Air Service Unit GAFC300N15ALNK the Right Air-Prep Unit?
Choose this GAFC300N15ALNK when your line needs a 1/2in port and a regulated ceiling of 0.4 MPa. The L type tops out at 0.4 MPa, so if the machine may ever require more pressure, this is the wrong part. The automatic drain suits unattended operation, and the nylon bowl is a build choice - confirm it fits your surroundings, as the catalogue gives no material-specific ratings. The reverse-flow (reflux) valve is fitted, and the PT thread carries a gauge scale of MPa/psi if a gauge is added later. Spares are orderable as GAFR300-15 and GAL300-15. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the regulated 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 GAFC300N15ALNK FAQ
The GAFC300N15ALNK operates from 0.15 to 0.4 MPa (20-58 psi), with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It has a 40 um element, a 60 cc drain bowl, a 98 cc oil bowl, and weighs 1020 g. The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32.
The N after the port code means no gauge is supplied. If you need to read the set pressure, you can add a gauge to the 1/8in connection on the GAFC300 body. The PT thread means any added gauge should read in MPa and psi.
