About the Airtac GAFC Air Service Unit GAFC40015ASWK
This GAFC40015ASWK is a two-piece F.R.L. combination: a GAFR400-15 filter-regulator (filter and regulator share one body) joined to a GAL400-15 lubricator on a T-bracket with quick clamps. Air is filtered and set to pressure in the first body, then the lubricator adds a controlled oil mist last, so oil never passes back through the regulator seat. With a 1/2in port and 1810 g mass, this size class suits a machine header or a multi-station line, and needs a proper panel or frame mount rather than support from the tubing.
The working range is 0.15-0.9 MPa (20-130 psi) with a 5 um element that traps far finer particles for precision valves or instrument air, at the cost of more frequent element service. The automatic drain clears condensate without an operator, which is decisive for unattended or wet lines. The 100 cc condensate bowl and 185 cc oil bowl are the real driver of service intervals, and the 5 um element means the element itself will need attention sooner than a 40 um version.

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 GAFC40015ASWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging line with the 5 um element, ensuring fine particles are trapped before they reach sensitive spools and seats.
Machine tool header
Supply a machine tool's air header where a 1/2in port and 1810 g mass support multiple actuators, with the automatic drain handling condensate in a wet shop environment.
Multi-station assembly
Run a multi-station assembly fixture where the 100 cc condensate bowl and 185 cc oil bowl extend time between service visits, and the 5 um element protects downstream tooling.
Is the Airtac GAFC Air Service Unit GAFC40015ASWK the Right Air-Prep Unit?
Choose the GAFC400 body for a 1/2in port with a 6000 L/min flow curve plotted at 0.7 MPa inlet, a step up from the GAFC300's 3500 L/min envelope. The PC bowl is the standard build choice; confirm it suits your surroundings, as the catalogue gives no material-specific temperature or chemical data. The automatic drain (A) removes condensate without operator action, and the 5 um element (W) filters finer particles than the standard 40 um. A circular gauge is fitted, reading MPa/psi on the PT thread. The reverse-flow (reflux) valve is fitted, shown as a separate pneumatic symbol in the catalogue. Spares are orderable as GAFR400-15 and GAL400-15. If the line must stay oil-free, choose a plain GAFR filter-regulator instead. Max supply 1.0 MPa leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan a supply near 1.0 MPa if you need 0.9 MPa out.
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 GAFC40015ASWK FAQ
The GAFC40015ASWK operates at 0.15-0.9 MPa (20-130 psi) with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. The condensate bowl holds 100 cc and the oil bowl holds 185 cc, with a total weight of 1810 g.
The K indicates a reverse-flow (reflux) valve is fitted. The catalogue shows this as a separate pneumatic symbol on the unit. It is an ordering difference to note when specifying the assembly, and the spares remain the GAFR400-15 and GAL400-15 units.
