About the Airtac GAFC Air Service Unit GAFC40015ALK
The GAFC40015ALK is a two-piece F.R.L. combination: a filter-regulator body handles filtration and pressure setting, then a separate lubricator adds a controlled oil mist downstream. This 1/2in unit operates in the lower pressure band of 0.15-0.4 MPa (20-58 psi) and comes with a 40 um element, an automatic drain, and a circular gauge reading MPa/psi.
With a 100 cc condensate bowl and a 185 cc oil bowl, this 1810 g assembly suits medium-sized machinery where the lower pressure ceiling is acceptable. The reverse-flow (reflux) valve is fitted as an ordering option, and the two units are separately orderable as GAFR400-15 and GAL400-15 for straightforward servicing.

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 GAFC40015ALK Is Used
Precision pressure setting
Set regulated air at 0.3 MPa for a delicate pneumatic clamping fixture on a CNC machine, where the lower range gives finer adjustment resolution.
Assembly line lubrication
Feed a multi-spindle nutrunner on an assembly line with filtered, regulated air and a metered oil mist to keep tool internals lubricated.
Test bench air supply
Supply a pneumatic test bench that validates valve actuation at controlled low pressures, relying on the automatic drain to handle condensate during long test cycles.
Is the Airtac GAFC Air Service Unit GAFC40015ALK the Right Air-Prep Unit?
Choose the GAFC40015ALK when your line needs 1/2in ports and the lower 0.15-0.4 MPa (20-58 psi) range. The automatic drain clears condensate without operator attention, while the PC bowl is a build choice - confirm it suits your surroundings since the catalogue gives no material-specific ratings. The fitted gauge reads MPa/psi on the default PT thread, and the K code adds the reverse-flow valve. If oil mist is unwanted downstream, omit the lubricator and select a plain GAFR filter-regulator instead. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 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 GAFC40015ALK FAQ
The GAFC40015ALK is a lower-pressure F.R.L. combination with a 1/2in port, working range 0.15-0.4 MPa (20-58 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), temperature range -5 to 70 C, 100 cc drain bowl, 185 cc oil bowl, and a weight of 1810 g. Recommended lubricant is ISO VG 32 or equivalent.
The K code specifies that a reverse-flow (reflux) valve is fitted to the GAFC40015ALK. The catalogue shows this as a separate pneumatic symbol, with its function detailed on a dedicated page. It is an ordering difference from the standard GAFC40015AL model.
