About the Airtac GAFC Air Service Unit GAFC300N15ALNW
This AirTAC GAFC300N15ALNW 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 1/2in port and 1020 g mass place it in the mid-range class, sized for a machine header feeding several actuators. Air is cleaned and set to pressure in the first body, then the lubricator adds a metered oil mist last, so oil never travels back through the regulator seat.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 5 um element trapping fine particles for sensitive valves. The nylon bowl holds 60 cc of condensate, while the separate oil bowl holds 98 cc. No gauge is supplied, so the set pressure cannot be read without adding one to the 1/8in gauge connection. Max pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi), with a -5 to 70 C operating range.

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 GAFC300N15ALNW 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 clearances and the lower pressure range prevents over-pressurizing sensitive actuators.
Light conveyor lubrication
Supply a short conveyor line with filtered, regulated air and a consistent oil mist to keep pneumatic cylinders moving smoothly, with the automatic drain handling condensate from humid plant air.
Test bench air supply
Provide clean, low-pressure air to a laboratory test bench checking valve response, where the 0.15-0.4 MPa range matches typical test pressures and the 98 cc oil bowl lasts through long test cycles.
Is the Airtac GAFC Air Service Unit GAFC300N15ALNW the Right Air-Prep Unit?
Choose this GAFC300N15ALNW when you need a 1/2in port with a lower 0.4 MPa ceiling and fine 5 um filtration. The automatic drain clears condensate without an operator, ideal for wet lines or unattended shifts. The nylon bowl is a build choice, not a performance upgrade, so confirm it suits your environment before ordering. The PT thread carries a gauge scale in MPa and psi if you add a gauge later. For oil-free air downstream, omit the lubricator and select a plain GAFR300-15 filter-regulator instead. Spare parts are orderable as GAFR300-15 and GAL300-15, both matching this body and port. 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, so plan your inlet pressure accordingly.
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 GAFC300N15ALNW FAQ
This F.R.L. combination 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). Temperature range is -5 to 70 C. The drain bowl holds 60 cc and the oil bowl holds 98 cc. Recommended lubricant is ISO VG 32. The complete unit weighs 1020 g with a 1/2in port.
The N after the port code means no gauge is supplied with this unit. The gauge connection is 1/8in, so you can add a circular gauge later if you need to read the set pressure. The first N, before the port code, indicates the bowl is made of nylon rather than polycarbonate.
