About the Airtac GAFC Air Service Unit GAFC300C15SN
This GAFC300C15SN combines a filter and regulator in one body with a separate lubricator, mounted on a shared T-bracket for a compact two-piece air prep train. The 1/2in port and 1020 g mass place it in the mid-range size class, suitable for feeding a single machine station or a short distribution line. Air enters, solids and moisture are removed, pressure is set to the 0.15-0.9 MPa (20-130 psi) range, and a controlled oil mist is added last, downstream of the regulator seat.
The metal bowl (C code) is specified here, and the common specification of 1.0 MPa max pressure and -5 to 70 C operation applies unchanged; confirm the material suits your environment. The 40 um element handles standard shop air, while the 60 cc condensate bowl and 98 cc oil bowl define the service interval. No gauge is supplied with this model, so the set pressure cannot be read without adding one to the 1/8in gauge connection.

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 GAFC300C15SN Is Used
Machine Tool Lubrication
Feed a clean, regulated air supply with metered oil mist to a CNC lathe's tool changer cylinder, where consistent lubrication extends seal life and reduces sticking.
Assembly Line Actuators
Supply a 1/2in header that powers multiple pneumatic actuators on an automotive assembly station, with the 60 cc bowl handling condensate between shifts.
Packaging Equipment
Protect a case packer's pneumatic valves and cylinders with filtered, regulated, lubricated air, reducing wear on high-cycle components in a dusty environment.
Is the Airtac GAFC Air Service Unit GAFC300C15SN the Right Air-Prep Unit?
Choose the GAFC300 body for a balance of flow and footprint, with the 1/2in port suiting applications that need more capacity than the 1/4in GAFC200 but less than the 3/4in GAFC500. The metal bowl is a build choice, not a performance upgrade, and the standard type regulates from 0.15 to 0.9 MPa (20-130 psi) with a max supply of 1.0 MPa. The semi-auto drain dumps condensate on each pressure drop, while the manual drain gives on-demand control. A 5 um element (W code) is available for finer filtration, and the PT thread with MPa/psi gauge scale is the default. If the line must stay oil-free, choose a plain GAFR filter-regulator instead of this lubricating set. 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 regulated range, so plan the 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 GAFC300C15SN FAQ
The GAFC300C15SN operates on air with a standard pressure range of 0.15-0.9 MPa (20-130 psi). Maximum pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). The 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 C code specifies a metal bowl, which is a build choice for the unit; the shared specification of 1.0 MPa max and -5 to 70 C does not change with material. The N after the port code means no gauge is supplied, so you would need to add one to the 1/8in gauge connection to read the set pressure.
