About the Airtac GAFC Air Service Unit GAFC400C15LNW
This AirTAC GAFC400C15LNW is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator is mounted beside them on a T-bracket. The 1/2in port and 1810 g mass place it in the mid-size class, suited to a machine header feeding several actuators. It regulates to a lower pressure band of 0.15-0.4 MPa (20-58 psi), with a 5 um element for finer filtration.
The metal bowl holds 100 cc of condensate and the oil bowl 185 cc, so service intervals are generous for a unit this size. With no gauge fitted, the 1/4in gauge connection is available if an operator needs to read the set pressure. The semi-auto drain dumps condensate on each pressure drop, while the manual drain gives on-demand control.

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 GAFC400C15LNW Is Used
Precision machining center
Feed a 1/2in line to a CNC spindle air curtain or tool changer with a regulated 0.4 MPa supply, keeping the pressure low and stable for sensitive components.
Assembly station header
Supply a multi-station assembly bench where multiple pneumatic screwdrivers or pick-and-place units need a consistent, lower-pressure air source without frequent adjustment.
Test rig air supply
Use it on a laboratory test jig that requires a clean, regulated air supply at 0.4 MPa or below, with the 5 um element protecting fine orifices in measurement equipment.
Is the Airtac GAFC Air Service Unit GAFC400C15LNW the Right Air-Prep Unit?
Choose this GAFC400C15LNW when your line needs 1/2in ports and a regulated output capped at 0.4 MPa. The metal bowl is a build choice for the surroundings, though the shared specification of 1.0 MPa max and -5 to 70 C applies to all bowl materials, so confirm it suits your environment. The 5 um element traps finer particles than the standard 40 um, at the cost of more frequent element service. The semi-auto and manual drains are both fitted, and the PT thread carries the default MPa/psi gauge scale if you add a gauge to the 1/4in connection. If the line must stay oil-free, omit the lubricator and choose a plain GAFR400-15 filter-regulator instead; the GAL400-15 lubricator is the matching spare here. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the 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 GAFC400C15LNW FAQ
The GAFC400C15LNW 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). It handles temperatures from -5 to 70 C and uses ISO VG 32 lubricant. The drain bowl holds 100 cc, the oil bowl 185 cc, and the unit weighs 1810 g.
The C code specifies a metal bowl, which is a build choice; the catalogue gives no performance difference between bowl materials, so confirm it suits your environment. The N after the port means no gauge is supplied, but the 1/4in gauge connection is there if you add one later.
