About the Airtac GAFC Air Service Unit GAFC400N10ALW
This AirTAC GAFC400N10ALW is an F.R.L. combination where the filter and regulator share one body, paired with a lubricator on a T-bracket. Air enters the 3/8" port, gets filtered to 5 um, pressure is set to 0.15-0.4 MPa (20-58 psi), then oil mist is added downstream. The nylon bowl holds 100 cc of condensate, while the oil bowl holds 185 cc, and the whole unit weighs 1810 g.
The two-piece build means one less inter-unit joint to seal compared to a three-piece filter-regulator-lubricator train. The automatic drain clears condensate without an operator, making it suitable for lines that run unattended. The circular gauge is fitted and reads in MPa/psi, matching the PT thread. For spares, the filter-regulator is orderable as GAFR400-10 and the lubricator as GAL400-10.

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 GAFC400N10ALW Is Used
Precision Assembly Stations
Feed a 3/8" line to a precision press or torque tool where the lower 0.4 MPa ceiling protects delicate mechanisms from over-pressure, while the 5 um element keeps fine particles out of sensitive valves.
Laboratory Air Supply
Supply filtered, regulated air to a lab bench with pneumatic actuators or small test fixtures. The automatic drain and 5 um filtration suit clean, low-pressure instrumentation air.
Packaging Line Sensors
Run a packaging machine's pneumatic sensors and small cylinders on a 3/8" line. The lower pressure range and fine filtration protect precision pilot valves from contamination and over-pressure.
Is the Airtac GAFC Air Service Unit GAFC400N10ALW the Right Air-Prep Unit?
Choose this GAFC400N10ALW when you need a 3/8" port with a lower pressure ceiling of 0.4 MPa, ideal for sensitive processes that must not see higher pressures. The 5 um element traps finer particles than the standard 40 um, but expect more frequent element service. The nylon bowl is a build choice; confirm it suits your environment since the catalogue gives no material-specific ratings. The automatic drain is fitted, and the gauge reads MPa/psi on the PT thread. If your line must stay oil-free, 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, so plan your inlet pressure accordingly.
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 GAFC400N10ALW FAQ
This F.R.L. combination 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). Temperature range is -5 to 70 C. The drain bowl holds 100 cc and the oil bowl 185 cc. Recommended lubricant is ISO VG 32. The unit weighs 1810 g with a 3/8" PT thread port.
The N before the port code specifies a nylon bowl. The catalogue lists PC, metal, and nylon options, all sharing the same 1.0 MPa max pressure and -5 to 70 C temperature range. Since no material-specific data is published, confirm nylon suits your environment. The 5 um element and automatic drain are separate options in this code.
