About the Airtac GAFC Air Service Unit GAFC400C10S
This GAFC400C10S is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a shared T-bracket with quick clamps. The 3/8in port suits mid-size machine circuits, and the metal bowl (100 cc condensate, 185 cc oil) handles continuous duty without the operator needing to watch a transparent reservoir.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 40 um element for general shop air. Because the filter and regulator share one body, there is one less inter-unit joint to seal compared to a three-piece train, and the lubricator adds oil mist only after pressure is set, so oil never travels back through the regulator seat.

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 GAFC400C10S Is Used
CNC spindle lubrication
Feed a 3/8in line to a CNC spindle air-oil lubrication unit, where the 40 um element protects metering orifices and the 185 cc oil bowl supports long shifts between refills.
Assembly station air prep
Mount on a multi-station assembly bench to supply filtered, regulated air to pneumatic screwdrivers and fixturing clamps, with the metal bowl standing up to shop-floor handling.
Packaging machine header
Use ahead of a packaging machine's cylinder bank, where the 6000 L/min plotted flow envelope at 0.7 MPa inlet provides a sizing reference for peak demand without over-specifying.
Is the Airtac GAFC Air Service Unit GAFC400C10S the Right Air-Prep Unit?
Choose the GAFC400 body when a 3/8in port with a 1810 g mass is appropriate for your panel or frame - it is heavier than the GAFC300 (1020 g) and should be bolted down, not supported by tubing. The metal bowl is a build choice; the catalogue gives no impact or chemical data, so confirm it suits your environment. This model ships with both semi-auto and manual drains: the semi-auto dumps condensate each time pressure drops, while the manual handle gives on-demand draining.
The circular gauge is fitted and reads in MPa/psi for the PT thread. For oil-free downstream air, omit the lubricator and select a plain GAFR400-10 filter-regulator instead; the lubricator here is meant to carry ISO VG 32 oil. Spares are orderable as GAFR400-10 and GAL400-10. With a 1.0 MPa max supply, you have only about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan inlet pressure near 1.0 MPa if you need the full output.
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 GAFC400C10S FAQ
The GAFC400C10S operates at 0.15-0.9 MPa (20-130 psi) with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. Temperature range is -5 to 70 C. It has a 100 cc drain bowl and 185 cc oil bowl, weighs 1810 g, and uses ISO VG 32 oil. The 40 um element handles general filtration, and the PT thread carries a MPa/psi gauge scale.
The C code specifies a metal bowl as a build choice for the GAFC400C10S. The catalogue lists the same pressure and temperature limits for all bowl materials, so this is about physical robustness in your specific environment rather than a performance upgrade. Confirm the metal bowl suits your surroundings before ordering, since no chemical or impact ratings are published.
