About the Airtac GAFC Air Service Unit GAFC400C15SK
This AirTAC GAFC400C15SK is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator is mounted beside it on a T-bracket. With a 1/2in port and a 1810 g mass, it suits medium-sized machine headers where a 3/8in GAFC300 would be undersized and a 3/4in GAFC500 is more than needed. The metal bowl is specified by the C code, and the 40 um element handles standard shop air.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum. The 100 cc condensate bowl and 185 cc oil bowl mean fewer service stops than the 60 cc and 98 cc bowls on a GAFC300. A circular gauge is fitted, reading in MPa and psi for the PT thread. The reverse-flow (reflux) valve is included, which the catalogue draws as a separate pneumatic symbol.

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 GAFC400C15SK Is Used
CNC coolant valves
Feed a 1/2in line to coolant solenoid valves on a CNC lathe, where the 100 cc bowl handles condensate from frequent compressor cycling.
Assembly station headers
Supply a multi-fixture assembly bench with regulated air for pneumatic presses and screwdrivers, using the 185 cc oil bowl to keep tooling lubricated.
Packaging line actuators
Run a carton-sealing machine's cylinder bank from this unit, where the 1810 g mass suits a fixed frame mount and the semi-auto drain needs no operator attention.
Is the Airtac GAFC Air Service Unit GAFC400C15SK the Right Air-Prep Unit?
Choose the GAFC400 body when your line needs 1/2in ports and the service interval that 100 cc and 185 cc bowls provide. The metal bowl is a build choice; confirm it suits your surroundings, since the -5 to 70 C rating is shared across all bowl materials. The semi-auto drain dumps condensate on pressure drop, and the manual drain gives on-demand control. The 40 um element is the standard grade; step to the 5 um W option for finer filtration. The PT thread carries a gauge with an MPa/psi scale. The K code adds the reverse-flow valve. Spares are orderable as GAFR400-15 and GAL400-15. With a 1.0 MPa max supply, you have about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range.
Quick checklist
- ✓ Body size for your peak flow (1/2" 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 GAFR400-15 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC400C15SK FAQ
It operates from 0.15 to 0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. The drain bowl holds 100 cc, the oil bowl 185 cc, and the unit weighs 1810 g.
The C code specifies a metal bowl instead of the standard PC. The catalogue does not publish separate temperature or chemical data for the materials, so confirm the metal suits your environment. The pressure rating and temperature range are identical across bowl options.
