About the Airtac GAFC Air Service Unit GAFC300N15LN
This GAFC300N15LN is a two-piece F.R.L. combination: a filter-regulator in one body paired with a lubricator on a shared T-bracket. The 1/2in port and 1020 g mass place it in the mid-size class, suitable for feeding a single machine station or a small bank of actuators. Air is filtered and regulated first, then the lubricator adds a controlled oil mist last, so oil never passes back through the regulator seat.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a maximum supply of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The 40 um element handles standard shop air, while the nylon bowl and semi-auto plus manual drain cover routine condensate removal. No gauge is fitted, so the 1/8in gauge connection is available if you add one later.

Constituent units, orderable separately as spares: GAFR300-15 filter & regulator, GAL300-15 lubricator — both share this body and port. A GAFC has two units, not three: the filter and the regulator are one body.

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 GAFC300N15LN Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a small assembly station where a 0.4 MPa ceiling protects sensitive actuators from over-pressure.
Single machine station
Supply a dedicated machine station with a 1/2in line, using the 60 cc condensate bowl and 98 cc oil bowl to extend service intervals between checks.
Low-pressure test rig
Set up a low-pressure test rig for components rated under 0.4 MPa, relying on the lower-pressure regulator to hold a stable setpoint without a gauge.
Is the Airtac GAFC Air Service Unit GAFC300N15LN the Right Air-Prep Unit?
Choose this GAFC300N15LN when your circuit needs a 1/2in port and a regulated ceiling of 0.4 MPa, not the standard 0.9 MPa. The nylon bowl is a build choice, not a performance upgrade, so confirm it suits your environment. The semi-auto drain dumps condensate on each pressure drop, with a manual drain for on-demand use. The 40 um element is the standard grade; step to the W option for 5 um filtration if your valves need finer protection. The PT thread carries a gauge scale of MPa/psi, but this model ships without a gauge, so plan to read pressure through the 1/8in connection or add one. Spares are orderable as GAFR300-15 and GAL300-15. 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 GAFC300N15LN FAQ
This F.R.L. combination operates from 0.15 to 0.4 MPa (20-58 psi), with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. The drain bowl holds 60 cc, the oil bowl holds 98 cc, and the unit weighs 1020 g. The element grade is 40 um.
The N after the port code means no gauge is supplied. The GAFC300 body has a 1/8in gauge connection, so you can add a compatible gauge to read the set pressure. Without one, you cannot verify the regulated output visually, so plan to fit a gauge if your process requires monitoring.
