About the Airtac GAFC Air Service Unit GAFC400C10LWK
This GAFC400C10LWK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared bracket. The 3/8in port and 1810 g mass place it in the mid-size class, suited for a machine header feeding several actuators. It regulates to a lower pressure band of 0.15-0.4 MPa (20-58 psi) and filters to 5 um.
The metal bowl holds 100 cc of condensate, while the oil bowl holds 185 cc, so the service interval is generous for a unit this size. The circular gauge is fitted and reads in MPa/psi. A reverse-flow (reflux) valve is also fitted, 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 GAFC400C10LWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging line where the 5 um element protects fine internal clearances and the 0.4 MPa ceiling prevents over-pressurizing sensitive actuators.
Machine tool lubrication
Supply a metered oil mist to a multi-spindle drilling head, where the 185 cc oil bowl supports extended runs between refills and the lower pressure range suits the tool's feed cylinders.
Test bench air supply
Provide clean, regulated air at a controlled low pressure to a laboratory test fixture, with the 5 um element removing particles that could skew measurement results.
Is the Airtac GAFC Air Service Unit GAFC400C10LWK the Right Air-Prep Unit?
Choose the GAFC400C10LWK when your line needs fine filtration at 5 um and a regulated ceiling of 0.4 MPa (20-58 psi). The metal bowl is a build choice, not a performance upgrade - the 1.0 MPa max and -5 to 70 C rating are identical across bowl materials, so confirm it suits your surroundings. The semi-auto drain clears condensate each time pressure drops, with a manual backup for scheduled service. The PT thread carries a gauge scaled in MPa/psi, matching the default for many export markets. The reverse-flow valve is fitted per the K code. If the line must stay oil-free, omit the lubricator and order the GAFR400-10 filter-regulator alone; otherwise the GAL400-10 lubricator is the matching spare. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the regulated range, so plan the 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 GAFC400C10LWK 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). It filters to 5 um and works in -5 to 70 C. The drain bowl holds 100 cc and the oil bowl 185 cc. Recommended lubricant is ISO VG 32. The complete unit weighs 1810 g.
The C code specifies a metal bowl, which is a build choice - the catalogue does not claim it is stronger or more resistant than PC or nylon. The L type limits regulation to 0.4 MPa, which suits applications that must not exceed that pressure. The 5 um element and reverse-flow valve are separate options that come with this configuration.
