About the Airtac GAFC Air Service Unit GAFC400C15ALNW
This AirTAC GAFC400C15ALNW is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator is a separate unit mounted on the same T-bracket. Air is cleaned and set to pressure in the first body, then a metered oil mist is added downstream, so oil never passes back through the regulator seat. With a 1/2in port and a 1810 g mass, it suits medium-size machine headers or multi-station lines where a steady oil supply matters.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), and the 5 um element traps finer particles than the standard 40 um grade, which is useful ahead of precision valves. A metal bowl is specified here, and the common specification of 1.0 MPa max and -5 to 70 C applies; confirm the material suits your surroundings. The automatic drain clears condensate without an operator, and the 100 cc condensate bowl plus 185 cc oil bowl set the service rhythm.

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 GAFC400C15ALNW Is Used
Precision valve stations
Feed a bank of fine pneumatic valves on a packaging line where the 5 um element protects tight clearances and the lower pressure range prevents over-stroking sensitive actuators.
Medium machine headers
Supply a 1/2in header on a multi-station assembly machine, where the automatic drain handles condensate from a wet compressor line without daily manual attention.
Lubricated tool circuits
Run a lubrication-dependent tool such as an air screwdriver or a small cylinder circuit, where the 185 cc oil bowl keeps the mist steady between refills.
Is the Airtac GAFC Air Service Unit GAFC400C15ALNW the Right Air-Prep Unit?
The GAFC400 body offers 3/8in and 1/2in ports; this 1/2in version is the larger of the two. The catalogue flow curve is plotted to 6000 L/min at 0.7 MPa inlet, so it sits between the GAFC300's 3500 L/min envelope and the GAFC500's 7000 L/min figure. The L type caps the regulated range at 0.4 MPa, which is about 44% of the standard 0.9 MPa ceiling, so confirm the machine never needs more than that. The A code specifies an automatic drain, the metal bowl is a build choice, and the N after the port means no gauge is supplied - the 1/4in gauge connection is there if you add one later. The 5 um element means more frequent service than a 40 um grade, and the PT thread carries an MPa/psi gauge scale when fitted. Spares are orderable as the GAFR400-15 filter & regulator and the GAL400-15 lubricator. Max supply 1.0 MPa 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 GAFC400C15ALNW FAQ
This lower-pressure unit 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). The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. It has a 100 cc condensate bowl and a 185 cc oil bowl, and the complete assembly weighs 1810 g.
The N after the port code means no gauge is supplied with this unit. The GAFC400 body has a 1/4in gauge connection, so you can fit a circular gauge later if you need to read the set pressure. The PT thread version uses an MPa/psi scale when a gauge is added.
