About the Airtac GAFC Air Service Unit GAFC400C15ASNW
This GAFC400C15ASNW is a two-piece F.R.L. combination: a filter-regulator in one 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 feeding several actuators.
Air is filtered and regulated in the first body, then the lubricator adds a controlled oil mist last, so oil never passes back through the regulator seat. The 5 um element traps finer particles than the standard 40 um, and the metal bowl is specified by the C code. The automatic drain clears condensate without an operator, and the 100 cc drain bowl plus 185 cc oil bowl set the service interval.

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 GAFC400C15ASNW Is Used
Machine tool coolant systems
Feed a 1/2in header on a CNC lathe or milling machine, where the 5 um element protects precision coolant valves from fine particulate.
Assembly line pallet stops
Supply multiple pneumatic pallet stops on an automotive assembly line, with the automatic drain handling condensate from a wet compressor line.
Packaging machine air prep
Prepare air for a case packer's film-seal cylinders and grippers, where the 185 cc oil bowl supports sustained lubrication over long shifts.
Is the Airtac GAFC Air Service Unit GAFC400C15ASNW 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 if you need more margin. The metal bowl is named by the C code, and the common specification of 1.0 MPa max and -5 to 70 C applies regardless of material, so confirm the metal suits your surroundings. The A code specifies an automatic drain, ideal for unattended lines, and the 5 um element trades finer filtration for more frequent service.
The N after the port means no gauge is supplied; the 1/4in gauge connection remains available if you add one later. The PT thread carries a MPa/psi scale on any gauge fitted. Spare parts are orderable as GAFR400-15 and GAL400-15. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan a supply near the maximum if you need the full regulated output.
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 GAFC400C15ASNW FAQ
The working pressure range is 0.15-0.9 MPa (20-130 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 holds 185 cc, with a total weight of 1810 g.
The C code specifies a metal bowl, a build choice you should confirm suits your environment since the catalogue lists no material-specific ratings. The N after the port means no gauge is supplied, so the 1/4in gauge connection is left open for a field-installed gauge if you need to read the set pressure.
