About the Airtac GAFC Air Service Unit GAFC400C15LN
This AirTAC GAFC400C15LN is a two-piece F.R.L. combination: a filter and regulator share one body, and a lubricator is mounted beside it on a T-bracket with quick clamps. It handles a 1/2in port and weighs 1810 g, so it suits a machine header or a small multi-station line rather than a single actuator.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 40 um element and a metal bowl. The 100 cc condensate bowl and 185 cc oil bowl set the service rhythm, and the gauge connection is 1/4in if you add one later. The catalogue flow curve is plotted to 6000 L/min at 0.7 MPa inlet, which helps when sizing against a neighbouring body.

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 GAFC400C15LN Is Used
Precision pressure set
Set a lathe's air chuck to a stable 0.3 MPa with the lower-pressure regulator, while the lubricator meters oil to the chuck cylinder seals.
Packaging line feed
Feed a carton erector's pneumatic sensors and small cylinders on a 1/2in header, with the 100 cc bowl catching water from a humid plant air supply.
Multi-station assembly
Supply a four-station assembly bench where each station has its own valve manifold, relying on the 185 cc oil bowl to keep cycle times consistent between top-ups.
Is the Airtac GAFC Air Service Unit GAFC400C15LN the Right Air-Prep Unit?
Choose the GAFC400C15LN when your line needs 1/2in ports and a regulated band that tops out at 0.4 MPa. The metal bowl is specified by the C code, and the shared specification (1.0 MPa max, -5 to 70 C) does not change with bowl material, so confirm the metal suits your surroundings. The semi-auto drain dumps condensate on each pressure drop, with a manual drain for on-demand use, and the 40 um element is the standard grade. No gauge is supplied, so the set pressure cannot be read without adding one on the 1/4in connection; the PT thread carries an MPa/psi scale if you fit the circular gauge. The two units are orderable separately as the GAFR400-15 filter & regulator and the GAL400-15 lubricator. Because the lubricator adds oil mist last, choose a plain GAFR if the line must stay oil-free. A 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 GAFC400C15LN FAQ
This lower-pressure F.R.L. combination operates from 0.15 to 0.4 MPa (20-58 psi), with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It works in -5 to 70 C temperatures, holds a 100 cc condensate bowl and a 185 cc oil bowl, and weighs 1810 g. Use ISO VG 32 oil in the lubricator.
The C code specifies a metal bowl as a build choice; the catalogue gives no impact or chemical data, so confirm it suits your environment. The N after the port means no gauge is supplied, so you cannot read the set pressure without adding one on the 1/4in gauge connection.
