About the Airtac GAFC Air Service Unit GAFC400N10LNWK
This AirTAC GAFC400N10LNWK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. The 3/8in port and 1810 g mass place it in the mid-size class, suited for machine headers or multi-station lines where a compact footprint matters. It operates in the lower-pressure band of 0.15-0.4 MPa (20-58 psi), with a 5 um element for finer filtration.
The nylon bowl holds 100 cc of condensate, while the separate oil bowl holds 185 cc, so service intervals are generous for this class. No gauge is fitted; the 1/4in gauge connection allows a later addition. A reverse-flow valve is included, and the semi-auto plus manual drain pair gives both automatic dumping on pressure drop and on-demand operation.

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 GAFC400N10LNWK Is Used
Precision Drilling Spindle
Feed a 3/8in line to a precision drilling spindle where the lower 0.4 MPa ceiling prevents over-force on small diameter bits, and the 5 um element keeps fine abrasive dust out of the spindle bearings.
Assembly Station Header
Supply a multi-station assembly bench with regulated air at 0.3 MPa for pneumatic screwdrivers, where the 185 cc oil bowl keeps lubricant flowing to several tools between refills.
Leak Test Fixture
Use on a leak test fixture that requires stable low pressure around 0.2 MPa, with the semi-auto drain handling condensate from a humid compressor line without operator attention.
Is the Airtac GAFC Air Service Unit GAFC400N10LNWK the Right Air-Prep Unit?
Choose the GAFC400 body when you need 3/8in ports and a 6000 L/min flow envelope at 0.7 MPa inlet, stepping down from the GAFC500's 3/4in size when space is tighter. The nylon bowl is a material choice, not a performance upgrade; confirm it suits your environment. The semi-auto drain clears condensate on each pressure drop, with a manual backup for scheduled maintenance. The 5 um element traps finer particles than the standard 40 um, but expect more frequent element service. The lower-pressure L type tops out at 0.4 MPa, so verify your actuators never need more. No gauge is supplied; the 1/4in connection accepts one later. The reverse-flow valve is fitted per the K code. Spares are the GAFR400-10 filter-regulator and GAL400-10 lubricator. The 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 (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 GAFC400N10LNWK FAQ
The GAFC400N10LNWK 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.
The N code after the port means no gauge is supplied. The GAFC400 body has a 1/4in gauge connection, so you can add a circular gauge later if you need to read the set pressure. The PT thread uses an MPa/psi scale on compatible gauges.
