About the Airtac GAFC Air Service Unit GAFC400C10ASW
This GAFC400C10ASW is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator bolts on downstream through a T bracket. With a 3/8" port and a 1810 g mass, it suits mid-size machine headers where a single point of air preparation feeds several actuators. The metal bowl holds 100 cc of condensate and the oil bowl 185 cc, so service intervals are measured in shifts, not hours.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with the 5 um element trapping fine particles before they reach precision valves. A circular gauge is fitted, reading MPa and psi on the PT thread scale. The automatic drain clears water without an operator, which matters when the unit sits high on a frame or in a hard-to-reach spot.

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 GAFC400C10ASW Is Used
CNC coolant valves
Feed a 3/8" header that supplies solenoid valves on a CNC lathe's coolant system. The 5 um element protects fine orifices, and the automatic drain keeps the bowl from filling during long unmanned cycles.
Assembly station manifolds
Mount on a panel above a multi-station assembly bench where operators use pneumatic screwdrivers. The 185 cc oil bowl maintains lubrication for several tools between refills, and the gauge lets you set pressure without guesswork.
Packaging line tensioners
Supply air to pneumatic tensioners on a film wrapping machine. The 100 cc condensate bowl with automatic drain handles moisture from a long unheated line, while the metal bowl resists accidental impacts from moving film rolls.
Is the Airtac GAFC Air Service Unit GAFC400C10ASW the Right Air-Prep Unit?
Choose this GAFC400C10ASW when you need 3/8" ports, a 5 um element, and an automatic drain in one package. The metal bowl is specified by the C code; the shared specification (1.0 MPa max, -5 to 70 C) is identical across bowl materials, so confirm the metal suits your environment rather than assuming it is tougher. The A drain means condensate is expelled automatically, while the standard S type regulates from 0.15 to 0.9 MPa (20-130 psi). A circular gauge is supplied, graduated in MPa with a psi ring for the default PT thread. The two units are orderable separately as GAFR400-10 and GAL400-10, so a clogged element or damaged bowl does not force a full replacement. If your line must stay oil-free, omit the lubricator and choose a plain GAFR filter-regulator instead. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan the inlet pressure carefully if you intend to run near the upper setpoint.
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 GAFC400C10ASW FAQ
This F.R.L. combination operates from 0.15 to 0.9 MPa (20-130 psi), with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. It has a 100 cc drain bowl and a 185 cc oil bowl, and the complete unit weighs 1810 g. The port size is 3/8" and the filtering grade is 5 um.
The C in the model code specifies a metal bowl. The catalogue lists PC, metal, and nylon as bowl options, and the pressure and temperature ratings are the same for all three. The metal bowl is a build choice for environments where the operator prefers the material, but you should confirm it suits your specific conditions. The automatic drain is fitted regardless of bowl material.
