Airtac GAFC Air Service Unit GAFC40015ALWK
The AirTAC Airtac GAFC Air Service Unit GAFC40015ALWK 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 - 0.4 MPa (20 - 58 psi).

About the Airtac GAFC Air Service Unit GAFC40015ALWK
This GAFC400 combines a filter-regulator and a lubricator on a single T-bracket, so the 1/2in port unit delivers air that is cleaned, set to pressure, then oil-misted in the last stage. The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), and the 5 um element traps fine particles for sensitive equipment.
The 100 cc condensate bowl and 185 cc oil bowl are both transparent PC, and the automatic drain clears water without an operator. At 1810 g, this size class needs a proper panel mount rather than tubing support, and the fitted circular gauge reads in MPa/psi for the PT thread.

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 GAFC40015ALWK Is Used
Low-Pressure Assembly Tools
Feed a 1/2in line to pneumatic screwdrivers or nutrunners on an assembly bench, where the 0.4 MPa ceiling prevents over-torquing and the 5 um element keeps tool internals clean.
Packaging Line Air Supply
Supply a carton-erecting station with regulated air at 0.3 MPa for cylinder actuation, while the automatic drain removes condensate from a line that runs multiple shifts unattended.
Machine Tool Lubrication
Provide oil-misted air to a small machining center's way-lubrication system, where the 185 cc oil bowl supports longer runs between refills and the lower pressure protects delicate metering units.
Is the Airtac GAFC Air Service Unit GAFC40015ALWK the Right Air-Prep Unit?
Choose this GAFC40015ALWK when your line needs 1/2in ports and a regulated ceiling of 0.4 MPa - the L type suits low-pressure circuits but cannot supply more if the machine later demands it. The automatic drain handles wet or unattended lines, while the 5 um element protects precision valves at the cost of more frequent service. The reverse-flow valve is fitted, and the PC bowl is a build choice; confirm it suits your surroundings. Spares are GAFR400-15 and GAL400-15, both orderable separately. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan the inlet pressure accordingly.
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 GAFC40015ALWK FAQ
This F.R.L. combination operates from 0.15 to 0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. The drain bowl holds 100 cc and the oil bowl 185 cc. Recommended lubricant is ISO VG 32, and the unit weighs 1810 g.
The L code sets the 0.15-0.4 MPa range for low-pressure circuits, while the W code specifies a 5 um element that traps finer particles than the standard 40 um. This combination suits precision pneumatic controls that need clean air at modest pressure, though the finer element requires more frequent replacement.
