About the Airtac GAFC Air Service Unit GAFC300N15S
This AirTAC GAFC300N15S is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a shared T-bracket with quick clamps. Air enters the 1/2in port, gets filtered by the 40 um element, and is regulated to a set pressure between 0.15-0.9 MPa (20-130 psi) before the lubricator adds a metered oil mist downstream.
The nylon bowls hold 60 cc for condensate and 98 cc for oil, giving a 1020 g unit that needs a proper panel or frame mount rather than tubing support. The circular gauge reads in MPa and psi, and the semi-auto drain dumps condensate each time pressure drops, with a manual drain for on-demand use.

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 GAFC300N15S Is Used
Precision Assembly Stations
Feed a single-station pneumatic press or a small indexing table where the 1/2in port and 40 um filtration keep actuation consistent, and the lubricator protects the valve and cylinder seals.
Packaging Line Actuators
Run a carton erector or a case taper with a 1/2in supply, using the 60 cc condensate bowl to handle moisture from a non-dried compressor line and the 98 cc oil bowl to reduce refill frequency.
Machine Tool Lubrication
Supply a small CNC coolant pump or a tool changer cylinder where regulated pressure at 0.15-0.9 MPa (20-130 psi) keeps the cycle stable and the oil mist reaches the moving parts.
Is the Airtac GAFC Air Service Unit GAFC300N15S the Right Air-Prep Unit?
Choose this GAFC300N15S when you need a 1/2in port with a nylon bowl and a standard 0.15-0.9 MPa (20-130 psi) range. The nylon bowl is a build choice, not a performance upgrade - the 1.0 MPa max and -5 to 70 C rating stay the same across all bowl materials, so confirm nylon suits your environment. The semi-auto drain clears on pressure drops, while the manual drain gives operator control; the 40 um element handles general shop air, and the fitted gauge shows MPa and psi on its PT thread dial.
For a line that must stay oil-free, skip this lubricator and choose a plain GAFR300-15 filter-regulator instead. Spare parts are orderable as GAFR300-15 and GAL300-15. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan your inlet pressure near 1.0 MPa if you need the full regulated output.
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 GAFC300N15S FAQ
The GAFC300N15S operates at 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It works in -5 to 70 C temperatures and uses ISO VG 32 lubricant. The drain bowl holds 60 cc, the oil bowl holds 98 cc, and the unit weighs 1020 g.
The N in the code before the port specifies a nylon bowl. It is a material choice, not a performance upgrade - the pressure and temperature ratings are identical to the PC or metal options. Confirm nylon is compatible with your environment, since the catalogue provides no chemical or impact data for bowl materials.
