About the Airtac GAFC Air Service Unit GAFC400C10ALNW
This AirTAC GAFC400C10ALNW is an F.R.L. combination that pairs a filter-regulator with a lubricator on a single T-bracket, so filtering, pressure setting and oil misting happen in a two-piece build. The 3/8in port and 1810 g mass place it in the mid-range size class, suited to a machine station or a small production line rather than a single handheld tool.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 5 um element trapping fine particles for sensitive valves. The metal bowl holds 100 cc of condensate and the oil bowl 185 cc, while the automatic drain clears water without an operator. No gauge is fitted, so the 1/4in gauge connection is there if you add one 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 GAFC400C10ALNW Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging machine, where the 5 um element protects tight clearances and the lower pressure range suits delicate actuation.
Assembly station air
Supply a multi-spindle nutrunner or a small indexing table on an assembly line, where the 185 cc oil bowl keeps lubrication consistent across a shift.
Instrument air feed
Provide clean, regulated air to a laboratory instrument or a test rig that runs at low pressure, with the automatic drain keeping the line dry in humid conditions.
Is the Airtac GAFC Air Service Unit GAFC400C10ALNW the Right Air-Prep Unit?
Choose this GAFC400C10ALNW when your circuit runs below 0.4 MPa and needs fine filtration plus automatic draining. The metal bowl is specified by the C code, and the shared specification of 1.0 MPa max and -5 to 70 C applies regardless of material, so confirm the metal suits your environment. The 5 um element filters finer than the standard 40 um but will need more frequent service, and the automatic drain removes condensate without manual attention.
The L type tops out at 0.4 MPa, so if your machine may ever need more pressure, step to the standard S type instead. The PT thread carries a gauge scale in MPa/psi, though no gauge ships with this model. Spare parts are the GAFR400-10 filter-regulator and the GAL400-10 lubricator, both orderable separately. Max supply of 1.0 MPa leaves about 0.6 MPa above the 0.4 MPa top of the range, giving you a comfortable buffer for supply fluctuations.
Quick checklist
- ✓ Body size for your peak flow (3/8" 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 GAFR400-10 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC400C10ALNW 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 a proof pressure of 1.5 MPa (215 psi). It works in temperatures from -5 to 70 C and uses ISO VG 32 oil. The drain bowl holds 100 cc and the oil bowl 185 cc, with a total weight of 1810 g.
The C code specifies a metal bowl as a build choice, and the N after the port means no gauge is supplied. The gauge connection is 1/4in if you want to add one. The metal bowl carries the same 1.0 MPa max and -5 to 70 C rating as the PC or nylon options, so confirm it fits your surroundings.
