About the Airtac GAFC Air Service Unit GAFC400C10ASWK
The GAFC400C10ASWK is a two-piece F.R.L. combination: a filter-regulator body (GAFR400-10) paired with a lubricator (GAL400-10) on a shared T-bracket. Air enters the 3/8" port, gets filtered and regulated to 0.15-0.9 MPa (20-130 psi), then the lubricator adds a metered oil mist last, downstream of the regulator seat.
This metal-bowl version carries a 5 um element for finer filtration, suited to precision valves or instrument air. The automatic drain clears condensate without operator intervention, and the circular gauge reads in MPa/psi. Weighing 1810 g with 100 cc and 185 cc bowls, it is a mid-size unit that needs a proper panel mount, not tubing support.

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 GAFC400C10ASWK Is Used
Precision valve actuation
The 5 um element and regulated output suit piloting precision pneumatic valves on a CNC machine tool, where fine particles could affect spool operation.
Assembly line lubrication
Feed a multi-station assembly fixture with filtered, regulated air and a controlled oil mist for pneumatic actuators, with the automatic drain handling condensate from a wet compressor line.
Instrument air for test rigs
Use it on a lab test bench where a 3/8" supply feeds gauges and small cylinders, relying on the 5 um element to protect sensitive instrumentation.
Is the Airtac GAFC Air Service Unit GAFC400C10ASWK the Right Air-Prep Unit?
Choose the GAFC400 body for 3/8" porting with a 6000 L/min flow envelope at 0.7 MPa inlet, a step up from the GAFC300's 3500 L/min curve. The metal bowl (C) is specified here; the shared specification of 1.0 MPa max and -5 to 70 C applies, so confirm the material suits your environment. The automatic drain (A) suits unattended lines, and the 5 um element (W) traps finer particles at the cost of more frequent service. The PT thread carries a MPa/psi gauge scale, and the reverse-flow (reflux) valve is fitted as an ordering difference. Spares are orderable as GAFR400-10 and GAL400-10. With a 1.0 MPa max supply, you have 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 GAFC400C10ASWK FAQ
The working pressure range is 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). It operates from -5 to 70 C and uses ISO VG 32 lubricant. The drain bowl holds 100 cc and the oil bowl 185 cc, with a total weight of 1810 g.
The K indicates a reverse-flow (reflux) valve is fitted, shown as a separate pneumatic symbol in the catalogue. It is an ordering difference on this unit; the valve's function details are covered on the catalogue's dedicated page.
