Airtac GAFC Air Service Unit GAFC400C15ASWK
The AirTAC Airtac GAFC Air Service Unit GAFC400C15ASWK is a genuine two-piece F.R.L. combination — a GA-series filter & regulator and a lubricator pre-assembled on one T-shape bracket with quick mounting clamps. It has 1/2" ports, a 5 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAFC Air Service Unit GAFC400C15ASWK
This AirTAC GAFC400C15ASWK is an F.R.L. combination that pairs a filter-regulator body with a lubricator on a shared T-bracket, so three functions come from just two joined units. The 1/2in port and 1810 g mass place it in the mid-range GAFC400 class, sized for a machine header or a small multi-station line rather than a single actuator.
Air enters the first body where the 5 um element removes fine particles and the regulator sets pressure between 0.15-0.9 MPa (20-130 psi). The lubricator then meters ISO VG 32 oil mist into the flow last, so oil never travels back through the regulator seat. A circular gauge with an MPa/psi scale is fitted, and the automatic drain clears the 100 cc condensate bowl without operator attention.

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 GAFC400C15ASWK Is Used
Machine Tool Lubrication
Feed a 1/2in header on a CNC lathe or milling machine, where the 5 um element protects precision spindles and the automatic drain keeps coolant-laden condensate from reaching tool changers.
Multi-Station Assembly
Supply a small palletized assembly line with several pneumatic cylinders, where the 185 cc oil bowl sustains lubrication across multiple shifts before a refill is needed.
Carton Erecting Equipment
Run a case erector or carton former that cycles rapidly, relying on the 100 cc condensate bowl and automatic drain to handle moisture from humid plant air without manual dumping.
Is the Airtac GAFC Air Service Unit GAFC400C15ASWK the Right Air-Prep Unit?
The GAFC400 body offers 3/8in and 1/2in ports; this 1/2in version suits higher-demand circuits, while the 3/8in GAFC40010 steps down for lighter duty. The metal bowl is specified by the C code, a build choice you should confirm against your environment, and the 5 um element traps finer particles than the standard 40 um at the cost of more frequent service. The automatic drain handles wet or unattended lines, and the PT thread carries an MPa/psi gauge scale for operators who read metric pressure. The reverse-flow (reflux) valve is fitted per the K code, shown as a separate symbol in the catalogue. Spares are orderable as GAFR400-15 and GAL400-15, so a worn element or bowl does not force a full replacement. With a 1.0 MPa max supply, you have about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range, so plan the inlet pressure accordingly if you need the full 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 GAFC400C15ASWK FAQ
This F.R.L. combination works with air at 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). It operates from -5 to 70 C and must not freeze. The drain bowl holds 100 cc, the oil bowl 185 cc, and the unit weighs 1810 g. Use ISO VG 32 or equivalent lubricant.
The C code specifies a metal bowl, a build choice for the GAFC400 body; the catalogue lists the same 1.0 MPa max pressure and -5 to 70 C range for all bowl materials, so confirm the metal suits your environment. The W code upgrades the element from 40 um to 5 um, trapping finer particles for sensitive valves or instruments, though the element will need more frequent service.
