About the Airtac GAFC Air Service Unit GAFC400N10S
This GAFC400N10S is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator is mounted on the same T-bracket. Air is cleaned and set to pressure first, then a metered oil mist is added downstream, so oil never travels back through the regulator seat.
With a 3/8in port and 1810 g mass, this unit suits medium machine headers or multi-actuator stations. The nylon bowl holds 100 cc of condensate and the oil bowl 185 cc, and the standard pressure range is 0.15-0.9 MPa (20-130 psi) with a 40 um element. The circular gauge reads in MPa and psi.

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 GAFC400N10S Is Used
CNC coolant valves
Feed a 3/8in line to solenoid valves on a CNC lathe, where regulated pressure keeps coolant flow consistent.
Assembly station headers
Supply a multi-fixture assembly bench with filtered, regulated air and oil mist for pneumatic screwdrivers.
Carton erector lines
Run a carton-forming machine that needs steady pressure for cylinders and a fine oil mist for slide bearings.
Is the Airtac GAFC Air Service Unit GAFC400N10S the Right Air-Prep Unit?
Choose the GAFC400N10S when you need a 3/8in port with a 1810 g body that handles medium flow duties. The nylon bowl is specified by the N before the port code; the catalogue gives no impact or chemical data, so confirm it suits your environment. The drain is the semi-auto plus manual pair: it dumps condensate on pressure drop and on demand. The 40 um element is the standard grade, and the fitted gauge shows MPa and psi on the PT thread. If you need finer filtration, the W option swaps to 5 um. Spares are the GAFR400-10 filter-regulator and GAL400-10 lubricator, both orderable separately. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated 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 GAFC400N10S FAQ
The GAFC400N10S operates at 0.15-0.9 MPa (20-130 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, and the recommended lubricant is ISO VG 32. The drain bowl holds 100 cc, the oil bowl 185 cc, and the unit weighs 1810 g.
The N before the port code specifies a nylon bowl, which is a build choice for the condensate and oil reservoirs. The catalogue does not provide material-specific temperature or impact ratings, so verify nylon suits your operating environment. The common specification of 1.0 MPa max and -5 to 70 C applies regardless of bowl material.
