Airtac GAFC Air Service Unit GAFC300N10ALN
The AirTAC Airtac GAFC Air Service Unit GAFC300N10ALN is a genuine two-piece F.R.L. combination — a GA-series filter & regulator and a lubricator pre-assembled on one T-shape bracket with quick mounting clamps. It has 3/8" ports, a 40 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).

About the Airtac GAFC Air Service Unit GAFC300N10ALN
This GAFC300 F.R.L. combination pairs a filter-regulator body with a separate lubricator unit, joined on a T-bracket with quick clamps. The 3/8in port and 1020 g mass place it in the mid-size class, suited for a single machine station or a small production line. Its lower-pressure regulator tops out at 0.4 MPa (20-58 psi), so it fits light-duty circuits that never need more than that ceiling.
The nylon bowl holds 60 cc of condensate while the oil bowl carries 98 cc of ISO VG 32 lubricant. The automatic drain clears water without an operator, and the 40 um element handles standard shop air. No gauge is fitted, so the set pressure cannot be read without adding one to the 1/8in gauge connection. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so there is ample inlet margin for stable regulation.

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 GAFC300N10ALN Is Used
Light Assembly Fixtures
Powers pneumatic clamps and small actuators on a bench assembly station where cycle pressure stays below 0.4 MPa. The automatic drain keeps condensate out of the tooling without daily attention.
Carton Erecting Machines
Supplies regulated air to the folding and sealing heads of a carton erector. The 60 cc drain bowl handles moisture from a humid packaging floor, and the 98 cc oil bowl keeps the mechanism lubricated through a shift.
Lab Air Bench
Feeds a small pneumatic test rig in a laboratory where operators set pressure below 0.4 MPa. The nylon bowl resists incidental solvent splashes, though you should confirm compatibility for your specific chemicals.
Is the Airtac GAFC Air Service Unit GAFC300N10ALN the Right Air-Prep Unit?
Choose this GAFC300N10ALN when your circuit runs below 0.4 MPa and you want the automatic drain to handle wet conditions. The nylon bowl is a build choice, not a performance upgrade - the catalogue gives no impact or chemical data for it, so confirm it suits your environment. The 40 um element is the standard grade; step to the W code for 5 um filtration if you feed precision valves. The PT thread carries a MPa/psi gauge scale, but this model ships without a gauge, so plan to add one at the 1/8in connection if operators need to read the setpoint. The lubricator adds oil mist last, downstream of the regulator, so if the line must stay oil-free, choose a plain GAFR filter-regulator instead. Spares are orderable as GAFR300-10 and GAL300-10. At 0.4 MPa, this L-type tops out at about 44% of the standard 0.9 MPa ceiling, so confirm your machine never needs more before committing.
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 GAFC300N10ALN FAQ
The working pressure range is 0.15-0.4 MPa (20-58 psi). Maximum pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). Temperature range is -5 to 70 C and it must not freeze. The drain bowl holds 60 cc and the oil bowl 98 cc. Recommended lubricant is ISO VG 32. The complete unit weighs 1020 g.
The N after the port code means no gauge is supplied. The gauge connection is 1/8in, so you can add a circular gauge there if operators need to verify the setpoint. Without one, you cannot read the regulated pressure directly from the unit.
