Airtac GAFC Air Service Unit GAFC300N15AL
The AirTAC Airtac GAFC Air Service Unit GAFC300N15AL 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 1/2" ports, a 40 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).

About the Airtac GAFC Air Service Unit GAFC300N15AL
This AirTAC GAFC300N15AL is a two-piece F.R.L. combination built for a 1/2in line. The first body houses the filter and regulator together, so air is cleaned and set to pressure before it reaches the lubricator stage. The second body adds a controlled oil mist downstream, keeping the regulator seat free of oil.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 40 um element and a nylon bowl. The automatic drain clears condensate without an operator, and the circular gauge reads in MPa and psi. At 1020 g, this unit suits a panel or frame mount rather than tubing support.

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 GAFC300N15AL Is Used
Precision pressure setting
Set a precise 0.3 MPa for a delicate clamping fixture on a benchtop assembly station, where the lower-pressure range gives finer adjustment authority.
Compact machine build
Feed a single 1/2in actuator on a packaging machine with filtered, regulated, and lubricated air from one compact two-piece unit on a T bracket.
Wet line service
Use the automatic drain on a humid production line to clear condensate from the 60 cc bowl without scheduled manual checks.
Is the Airtac GAFC Air Service Unit GAFC300N15AL the Right Air-Prep Unit?
Choose the GAFC300N15AL when your circuit needs a 1/2in port and a regulated ceiling of 0.4 MPa. The nylon bowl is specified by the N before the port code, and the automatic drain (A) handles wet or unattended lines. The L type is the lower-pressure option, so confirm the machine never needs more than 0.4 MPa before selecting it. A circular gauge is fitted, graduated in MPa with a psi ring for the default PT thread. The 40 um element is standard; upgrade to a 5 um element with the W code if finer filtration is needed. Spare parts are GAFR300-15 and GAL300-15, both orderable separately. 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 GAFC300N15AL FAQ
The GAFC300N15AL 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. It has a 60 cc drain bowl and a 98 cc oil bowl, weighs 1020 g, and uses ISO VG 32 lubricant. The element is 40 um.
The L specifies the lower-pressure type, regulating from 0.15 to 0.4 MPa instead of the standard 0.15 to 0.9 MPa. This suits applications needing a lower, more precisely controlled pressure. If your machine may require more than 0.4 MPa, select the standard S type instead.
