About the Airtac GAFC Air Service Unit GAFC400N15AL
This GAFC400N15AL 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 machine headers or multi-station lines where a smaller unit would struggle.
Air enters the first body where the 40 um element removes solids and moisture, and the lower-pressure regulator sets output between 0.15-0.4 MPa (20-58 psi). The lubricator then adds a metered ISO VG 32 oil mist downstream, so oil never passes back through the regulator seat. The nylon bowl holds 100 cc of condensate, with a separate 185 cc oil bowl.

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 GAFC400N15AL Is Used
Precision Assembly Station
Feed a multi-spindle screwdriver or press with regulated air at 0.3 MPa, where the lower-pressure range prevents over-force on delicate parts.
Packaging Line Header
Supply a bank of pneumatic cylinders on a carton-erecting machine, with the automatic drain handling condensate from a humid plant line.
Machine Tool Coolant Valve
Operate a coolant control valve on a CNC lathe, where the 1/2in port delivers enough flow and the 0.4 MPa ceiling matches the valve's rating.
Is the Airtac GAFC Air Service Unit GAFC400N15AL the Right Air-Prep Unit?
Choose this GAFC400N15AL when your circuit needs a 1/2in port and a lower regulated ceiling of 0.4 MPa (20-58 psi). The nylon bowl is a build choice; the catalogue gives no impact or chemical data, so confirm it suits your environment. The automatic drain clears condensate without operator attention, ideal for wet or unattended lines. A circular gauge is fitted, reading MPa/psi for the PT thread. Spares are orderable as GAFR400-15 and GAL400-15.
With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the 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 GAFC400N15AL FAQ
The working pressure range is 0.15-0.4 MPa (20-58 psi). Maximum pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). Operating temperature is -5 to 70 C. The drain bowl holds 100 cc and the oil bowl 185 cc. Recommended lubricant is ISO VG 32. The unit weighs 1810 g.
The L type regulates to a maximum of 0.4 MPa (20-58 psi), which suits applications needing a soft, consistent pressure without risk of over-pressurizing sensitive components. If your machine may ever require more than 0.4 MPa, the standard S type (0.15-0.9 MPa) would be the correct choice instead.
