About the Airtac GAFC Air Service Unit GAFC400C15SNW
This GAFC400C15SNW 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. The 1/2in port and 1810 g mass place it in the mid-size class, suited for feeding a multi-axis machine or a small production line.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 5 um element for finer filtration. The metal bowl is specified by the C code, and the unit carries both a 100 cc condensate bowl and a 185 cc oil bowl. No gauge is supplied; the 1/4in gauge connection is ready for one if you add it later.

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 GAFC400C15SNW Is Used
Precision machining center
Feed a CNC machining center's tool changer and spindle air system with the 5 um element, protecting precision valves from fine particulates.
Assembly line automation
Supply a multi-station assembly line where the 185 cc oil bowl keeps lubricated actuators running longer between services.
Packaging machinery
Power a case packer's pneumatic cylinders and grippers, with the metal bowl suited for a washdown-adjacent environment.
Is the Airtac GAFC Air Service Unit GAFC400C15SNW the Right Air-Prep Unit?
Choose the GAFC400 body when you need 1/2in ports and a 6000 L/min flow envelope (plotted at 0.7 MPa inlet) for a mid-size line. The metal bowl is a build choice; the common specification of 1.0 MPa max and -5 to 70 C applies to all bowl materials, so confirm it suits your environment. The semi-auto drain dumps on pressure drop, and the manual drain works on demand. The 5 um element traps finer particles than the standard 40 um, at the cost of more frequent service. The PT thread carries a gauge scale of MPa/psi, but this model has no gauge fitted. Spare parts are orderable as GAFR400-15 and GAL400-15. With a 1.0 MPa max supply, you have about 0.1 MPa 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 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 GAFC400C15SNW FAQ
The working pressure range is 0.15-0.9 MPa (20-130 psi). Maximum pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi). Operating temperature is -5 to 70 C. The condensate bowl holds 100 cc, the oil bowl holds 185 cc. Recommended lubricant is ISO VG 32. The unit weighs 1810 g.
The N after the port code means no gauge is supplied with this unit. The GAFC400 body has a 1/4in gauge connection, so you can add a compatible gauge later if you need to read the set pressure. The PT thread option would use an MPa/psi scale.
