About the Airtac GAFC Air Service Unit GAFC300N15SW
The GAFC300N15SW is a two-piece F.R.L. combination: a filter-regulator body followed by a lubricator, mounted on a shared T-bracket with quick clamps. This 1/2in port version weighs 1020 g and carries a 60 cc condensate bowl plus a 98 cc oil bowl, so it suits medium-sized machines where the air prep set is mounted on a panel or frame rather than supported by tubing.
Air enters the first body, where the 5 um element removes fine particles and the regulator sets pressure anywhere in the 0.15-0.9 MPa (20-130 psi) band. The lubricator then adds a metered ISO VG 32 oil mist downstream, so oil never travels back through the regulator seat. The nylon bowl is specified by the N code; the catalogue gives no impact or chemical data for bowl materials, so confirm it suits your environment before ordering.

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 GAFC300N15SW Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging line where the 5 um element protects fine internal passages from wear and the regulated 0.15-0.9 MPa range keeps actuation consistent.
Machine tool lubrication
Supply a small CNC machine's tool-changer cylinder with filtered, regulated air and a controlled oil mist, ensuring smooth operation without over-lubricating downstream components.
Assembly station air prep
Mount on a panel above a manual assembly bench to condition air for pneumatic screwdrivers and clamps, with the 60 cc drain bowl reducing how often an operator needs to empty condensate.
Is the Airtac GAFC Air Service Unit GAFC300N15SW the Right Air-Prep Unit?
Choose the GAFC300N15SW when you need a 1/2in port, standard-pressure F.R.L. set with fine 5 um filtration. The nylon bowl (N before the port) is a build choice, not a performance upgrade, and the semi-auto drain dumps condensate each time pressure drops while the manual drain gives on-demand control. The fitted circular gauge reads in MPa and psi, matching the default PT thread. If you need a coarser 40 um element, drop the W code; if you need a lower 0.15-0.4 MPa range, switch to the L type. The two units are orderable separately as GAFR300-15 and GAL300-15. With a 1.0 MPa max supply, you have about 0.1 MPa of headroom above the 0.9 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 GAFC300N15SW FAQ
This F.R.L. combination operates at 0.15-0.9 MPa (20-130 psi) with a 1.0 MPa (145 psi) max pressure and a 1.5 MPa (215 psi) proof pressure. It works in -5 to 70 C temperatures and uses ISO VG 32 lubricant. The 60 cc drain bowl and 98 cc oil bowl serve the 1/2in port body, which weighs 1020 g.
The N code before the port specifies a nylon bowl. The catalogue lists PC, metal, and nylon as options with the same 1.0 MPa max pressure and -5 to 70 C temperature range for all three. Nylon is a material choice, not a performance claim, so confirm it fits your operating environment before purchasing.
