About the Airtac GAFC Air Service Unit GAFC400C15ALNK
This F.R.L. combination pairs a filter-regulator body with a lubricator on a single T-bracket, so the air is cleaned, set to pressure, then oil-misted in that order. The GAFC400C15ALNK uses a 1/2in port and a lower-pressure regulator band of 0.15-0.4 MPa (20-58 psi), with a 40 um element and a metal bowl.
The unit weighs 1810 g and carries a 100 cc condensate bowl plus a 185 cc oil bowl. The automatic drain clears water without an operator, and the reverse-flow (reflux) valve is fitted. No gauge is supplied; the 1/4in gauge connection is ready for one if you add it later.

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 GAFC400C15ALNK Is Used
Precision machining centers
Feed a 1/2in line to a CNC spindle or tool changer where regulated 0.15-0.4 MPa air operates clamping fixtures and the lubricator protects sliding ways.
Assembly line stations
Supply a multi-station assembly bench with a controlled oil mist for pneumatic screwdrivers and push cylinders, with the automatic drain handling condensate from humid plant air.
Packaging equipment
Run a case sealer or label applicator that needs a steady lower pressure for grippers and sensors, while the metal bowl suits a washdown-adjacent area.
Is the Airtac GAFC Air Service Unit GAFC400C15ALNK the Right Air-Prep Unit?
The GAFC400 body suits medium-flow lines where the 6000 L/min plotted curve at 0.7 MPa inlet gives sizing headroom. The metal bowl is a build choice, not a performance upgrade, so confirm it fits your environment. The automatic drain is the right call for wet or unattended air systems, while the lower-pressure L type tops out at 0.4 MPa - if your machine may ever need more, pick the standard S type instead. The 40 um element handles general shop air, and the PT thread with no gauge means you must add one to read the setpoint. Spares are the GAFR400-15 filter-regulator and the GAL400-15 lubricator, 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 your inlet pressure with that margin in mind.
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 GAFC400C15ALNK FAQ
This lower-pressure unit operates at 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 works from -5 to 70 C, uses ISO VG 32 lubricant, has a 100 cc drain bowl and 185 cc oil bowl, and weighs 1810 g. The 40 um element and automatic drain are standard on this code.
The N after the port code means no gauge is supplied, so you cannot read the set pressure without adding one to the 1/4in gauge connection. The K indicates the reverse-flow (reflux) valve is fitted, which the catalogue shows as a separate pneumatic symbol. The metal bowl is named for the build but carries no special performance claims.
