About the Airtac GAFC Air Service Unit GAFC400C15LNWK
This AirTAC GAFC400C15LNWK is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator is mounted on the same T-bracket. The 1/2in port and 1810 g mass place it in the mid-size class, suited for feeding a multi-station machine header where several actuators draw from one prepared air supply.
The lower-pressure regulator is set for 0.15-0.4 MPa (20-58 psi), and the 5 um element traps fine particles for sensitive valves. The metal bowl holds 100 cc of condensate, while the separate oil bowl holds 185 cc. No gauge is fitted, so the 1/4in gauge connection is ready for an add-on if a readout is needed 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 GAFC400C15LNWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging line where the 5 um element protects tight clearances and the lower pressure range prevents over-energizing sensitive actuators.
Multi-station assembly
Supply a 1/2in header on a multi-station assembly machine, where the 100 cc drain bowl and 185 cc oil bowl reduce how often an operator must check fluid levels across a shift.
Low-pressure test rig
Use on a test bench that requires a stable 0.15-0.4 MPa (20-58 psi) supply for checking cylinder seals, where the metal bowl suits a workshop environment and the gauge port allows a panel-mounted readout.
Is the Airtac GAFC Air Service Unit GAFC400C15LNWK the Right Air-Prep Unit?
Choose the GAFC400 body for a 1/2in port with a 6000 L/min flow envelope (plotted at 0.7 MPa inlet), stepping down from the GAFC500's 7000 L/min curve when space is tighter. The metal bowl is a build choice; the catalogue gives no impact or chemical data, so confirm it suits your surroundings. The semi-auto drain dumps condensate on pressure drops, with a manual drain for on-demand use. The 5 um element filters finer than the standard 40 um, but expect more frequent element service. The L-type regulator tops out at 0.4 MPa, and the reverse-flow (reflux) valve is fitted. The gauge connection is 1/4in since no gauge ships. Spares are GAFR400-15 and GAL400-15. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the 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 GAFC400C15LNWK FAQ
The working pressure range is 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). The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. The drain bowl holds 100 cc and the oil bowl 185 cc, with a total weight of 1810 g.
The C code specifies a metal bowl, which is a build choice for the unit's surroundings; the catalogue does not provide impact or chemical resistance data, so confirm it fits your environment. The N after the port means no gauge is supplied, leaving a 1/4in gauge connection for adding one later if you need to read the set pressure.
