Airtac GAFC Air Service Unit GAFC40015ALNK
The AirTAC Airtac GAFC Air Service Unit GAFC40015ALNK 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 40 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).

About the Airtac GAFC Air Service Unit GAFC40015ALNK
This GAFC40015ALNK is an F.R.L. combination where the filter and regulator share one body, paired with a lubricator on a T-bracket. With a 1/2in port and 1810 g mass, it suits mid-size machine headers where a 3/8in GAFC300 would be undersized. The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), and the 40 um element handles standard shop air.
The automatic drain clears the 100 cc condensate bowl without operator attention, while the 185 cc oil bowl feeds the lubricator. No gauge is fitted, so the 1/4in gauge connection is the point to add one if the set pressure needs to be read. The reverse-flow valve is fitted per the K code, and the catalogue shows it as a separate pneumatic symbol.

Constituent units, orderable separately as spares: GAFR400-15 filter & regulator, GAL400-15 lubricator — both share this body and port. A GAFC has two units, not three: the filter and the regulator are one body.

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 GAFC40015ALNK Is Used
Machine tool coolant valves
Feed a 1/2in header on a CNC lathe where the lower-pressure range suits pilot valves and coolant actuators that never need more than 0.4 MPa.
Assembly station air manifolds
Supply a multi-fixture workbench with regulated air at 0.3 MPa for pneumatic clamps, keeping the pressure low enough to protect delicate part-holding fixtures.
Test rig pressure control
Use the 0.15-0.4 MPa band on a leak-test fixture where precise low-pressure regulation is required and the automatic drain keeps the bowl clear during long test cycles.
Is the Airtac GAFC Air Service Unit GAFC40015ALNK the Right Air-Prep Unit?
The GAFC400 body with a 1/2in port handles flows the catalogue plots to 6000 L/min at 0.7 MPa inlet, about 70% more than the GAFC300's 3500 L/min envelope. The PC bowl is the standard build, and the automatic drain suits unattended operation. The lower-pressure L type tops out at 0.4 MPa, so if the machine may ever need more, choose the S type instead. The 40 um element is the default; the W option gives 5 um for finer filtration. PT thread with the gauge scale in MPa/psi applies here, though no gauge is supplied. The reverse-flow valve is fitted, and the two units are orderable separately as GAFR400-15 and GAL400-15. A 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 GAFC40015ALNK FAQ
The working pressure range is 0.15-0.4 MPa (20-58 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and uses ISO VG 32 lubricant. The drain bowl holds 100 cc and the oil bowl 185 cc, with a total weight of 1810 g.
The N in the code after the port means no gauge is supplied. The gauge connection on the GAFC400 body is 1/4in, so a gauge can be added at that port if the set pressure needs to be monitored. The thread is PT with the scale in MPa/psi.
