About the Airtac GAFC Air Service Unit GAFC400C15SW
This AirTAC GAFC400C15SW is an F.R.L. combination where the filter and regulator share one body, and the lubricator is a separate unit mounted on the same T-bracket. With a 1/2in port and a 5 um element, it filters finer particles than the standard 40 um grade, suiting precision valves or instrument air where contamination control matters. The metal bowl is specified by the C code; the catalogue gives no impact or chemical data, so confirm it fits your environment.
The working pressure range is 0.15-0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum and a 1.5 MPa (215 psi) proof pressure. The 100 cc condensate bowl and 185 cc oil bowl mean the 1810 g unit needs less frequent attention than smaller bodies. Air is filtered and regulated first, then oil mist is added last, so the regulator seat never sees oil.

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 GAFC400C15SW Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging line where the 5 um element keeps fine particles out of pilot orifices and spool clearances.
Multi-station assembly
Supply a multi-station assembly machine with a 1/2in header, using the 6000 L/min envelope at 0.7 MPa inlet to size the feed for several actuators running in sequence.
Instrument air pre-treatment
Protect sensitive instrumentation or gauges downstream by filtering to 5 um and regulating pressure before the lubricator adds a controlled oil mist for moving parts.
Is the Airtac GAFC Air Service Unit GAFC400C15SW the Right Air-Prep Unit?
Choose the GAFC400 for a 1/2in line where the 6000 L/min flow envelope at 0.7 MPa inlet gives ample margin for a multi-station machine. The metal bowl is a build choice, not a performance upgrade; the shared specification is identical across PC, metal, and nylon. This model has both semi-auto and manual drains, so condensate dumps on pressure drop or on demand. The 5 um element traps finer particles than the 40 um standard but will need more frequent service. A circular gauge is fitted, reading MPa/psi for the default PT thread. The two units are orderable separately as GAFR400-15 and GAL400-15. If the line must stay oil-free, omit the lubricator and choose a plain GAFR instead. With a 1.0 MPa max supply, there is about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan a supply near maximum if you need the full 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 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1810 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 GAFR400-15 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC400C15SW FAQ
The working pressure range is 0.15-0.9 MPa (20-130 psi), with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. The condensate bowl holds 100 cc and the oil bowl holds 185 cc. Recommended lubricant is ISO VG 32. The unit weighs 1810 g and has a 1/2in port.
The C code specifies a metal bowl. The catalogue lists the same maximum pressure and temperature range for PC, metal, and nylon bowls, so the material choice does not change the rated specification. Confirm the metal bowl suits your specific environment, as the catalogue provides no impact or chemical resistance data for bowl materials.
