About the Airtac GAFC Air Service Unit GAFC400C10LW
This AirTAC GAFC400C10LW 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 and 1810 g mass place it in the mid-size class, suited for a machine header feeding several actuators. It filters to 5 um, regulates in the lower 0.15-0.4 MPa (20-58 psi) band, and then adds a metered oil mist downstream.
The metal bowl holds 100 cc of condensate and the separate oil bowl 185 cc, so the service interval is set by how wet the line is and how much oil the tools consume. The circular gauge is fitted and reads in MPa and psi for the default PT thread. With a 5 um element, finer particles are trapped than the standard 40 um grade, which protects precision valves but means more frequent element checks.

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 GAFC400C10LW Is Used
Low-pressure assembly tools
Feed a multi-spindle screwdriver or a light press that must never see more than 0.4 MPa. The 5 um element keeps fine wear particles away from the tool's internal valve, and the metal bowl suits a shop floor with occasional coolant splash.
Paint or coating lines
Supply a low-pressure air header for paint agitation or coating applicators where a consistent 0.15-0.4 MPa band is required. The lubricator adds a controlled oil mist to downstream air tools, while the 100 cc drain bowl collects water from a wet compressor line.
Test rigs and lab benches
Power a pneumatic test fixture that cycles at a set low pressure. The 5 um filtration protects a sensitive pressure regulator on the fixture, and the 185 cc oil bowl keeps a small lubricator running for a full shift without a refill.
Is the Airtac GAFC Air Service Unit GAFC400C10LW the Right Air-Prep Unit?
Choose the GAFC400C10LW when your circuit needs a 3/8in port and a regulated output capped at 0.4 MPa. The L type is for low-pressure duties only: if the machine may ever require more than 0.4 MPa, select a standard S type instead. The metal bowl is a build choice; the catalogue gives no impact or chemical data, so confirm it suits your surroundings. The semi-auto drain dumps condensate each time pressure drops, with a manual drain for on-demand use. The 5 um element is fitted for finer filtration, and the PT thread carries a gauge scaled in MPa and psi. Spares are orderable as the GAFR400-10 filter-regulator and GAL400-10 lubricator. 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.
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 GAFC400C10LW FAQ
It is a lower-pressure F.R.L. combination operating at 0.15-0.4 MPa (20-58 psi). Max pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). Temperature range is -5 to 70 C and it must not freeze. The drain bowl holds 100 cc and the oil bowl 185 cc. Recommended lubricant is ISO VG 32. The unit weighs 1810 g.
The C code specifies a metal bowl for the filter-regulator body. The catalogue does not publish impact, heat or chemical resistance data, so the choice is about the build environment. The working specification is identical to the PC or nylon options: 1.0 MPa max and -5 to 70 C. Confirm the metal suits your specific surroundings before ordering.
