About the Airtac GAFC Air Service Unit GAFC400N15ALWK
This AirTAC GAFC400N15ALWK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, joined on a 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 single point of air preparation is needed.
Air enters the first body where the 5 um element traps fine particles and the regulator sets pressure to 0.15-0.4 MPa (20-58 psi). The lubricator then adds a metered oil mist downstream, so oil never passes back through the regulator seat. The nylon bowl is specified by the N code, and the automatic drain clears condensate without operator attention.

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 GAFC400N15ALWK Is Used
Precision Machining Center
Feed a CNC machining center's tool changer with regulated air at 0.15-0.4 MPa, where the 5 um element protects sensitive solenoid valves from fine abrasive dust.
Assembly Line Lubrication
Supply a multi-station assembly line's pneumatic screwdrivers with filtered, regulated air and a controlled oil mist to keep tool mechanisms running smoothly.
Packaging Equipment
Power a case packer's film-sealing cylinders with a stable 0.15-0.4 MPa supply, while the automatic drain handles condensate from intermittent operation.
Is the Airtac GAFC Air Service Unit GAFC400N15ALWK the Right Air-Prep Unit?
The GAFC400 body offers 3/8in and 1/2in ports; this 1/2in version sits above the GAFC300's 3500 L/min envelope, with the catalogue curve plotted to 6000 L/min at 0.7 MPa inlet. The L type limits regulation to 0.15-0.4 MPa (20-58 psi), so confirm your actuators never need more than that ceiling. The 5 um element traps finer particles than the standard 40 um, but will need more frequent service. The automatic drain suits wet or unattended lines, while the nylon bowl is a build choice - confirm it suits your environment. The circular gauge reads in MPa/psi, and the reverse-flow valve is fitted per the K code. 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 this unit's regulated range.
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 GAFC400N15ALWK FAQ
This unit operates at 0.15-0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. The drain bowl holds 100 cc and the oil bowl 185 cc. Recommended lubricant is ISO VG 32. The complete assembly weighs 1810 g.
The N before the port code specifies a nylon bowl. The catalogue gives no temperature, chemical, or impact data for bowl materials, so confirm nylon suits your environment. The L code means lower pressure regulation, and the K code indicates the reverse-flow valve is fitted.
