About the Airtac GAFC Air Service Unit GAFC400C15ASNK
This AirTAC GAFC400C15ASNK is a two-piece F.R.L. combination: the filter and regulator share one body, and a lubricator is mounted on the same T-bracket. Air is cleaned and set to pressure in the first unit, then a metered oil mist is added downstream, so oil never travels back through the regulator seat. With a 1/2in port and 1810 g mass, it suits a machine header feeding several actuators rather than a single small cylinder.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 40 um element filtering the supply. The metal bowl is specified by the C code, and the automatic drain clears condensate without an operator. No gauge is fitted, so the set pressure cannot be read without adding one to the 1/4in gauge connection. A reverse-flow (reflux) valve is included, shown as a separate symbol in the catalogue.

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 GAFC400C15ASNK Is Used
Machine tool lubrication
Feed a filtered, regulated air supply with a controlled oil mist to a CNC lathe's tool changer and door actuators, where the 1/2in port matches the header.
Assembly line headers
Supply a multi-station assembly line's pneumatic valves and cylinders from a central 1/2in manifold, with the automatic drain handling condensate from a wet compressor.
Packaging equipment
Run a carton erector or case sealer's pneumatic cylinders with consistent pressure and lubrication, relying on the 100 cc condensate bowl to reduce maintenance stops.
Is the Airtac GAFC Air Service Unit GAFC400C15ASNK the Right Air-Prep Unit?
Choose the GAFC400 body for a 1/2in line where the GAFC300's 3500 L/min envelope at 0.7 MPa inlet is too small; this model's curve is plotted to 6000 L/min at 0.7 MPa inlet. The metal bowl is a build choice, and the automatic drain suits unattended operation. The standard type regulates 0.15-0.9 MPa (20-130 psi), and the PT thread carries an MPa/psi gauge scale if you add a gauge later. The 40 um element is the default; a 5 um element (W) traps finer particles but needs more frequent service. Spares are orderable as GAFR400-15 and GAL400-15. Since the lubricator adds oil mist, choose a plain GAFR filter-regulator if the line must stay oil-free. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 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 GAFC400C15ASNK FAQ
This F.R.L. combination operates on air from 0.15 to 0.9 MPa (20-130 psi), with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. It has a 100 cc drain bowl and a 185 cc oil bowl, and the unit weighs 1810 g.
The N in the code after the port means no gauge is supplied. The GAFC400 body has a 1/4in gauge connection, so you can add a compatible gauge if you need to read the set pressure. The PT thread uses an MPa/psi scale on standard AirTAC gauges.
