About the Airtac GAFC Air Service Unit GAFC400C15ASW
This AirTAC GAFC400C15ASW 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 1/2in port and 1810 g mass place it in the mid-range class, sized for a machine header or a small multi-station line rather than a single actuator.
Air enters the first body where the 5 um element traps fine particles and the regulator sets pressure to 0.15-0.9 MPa (20-130 psi). The lubricator then adds a metered oil mist downstream, so oil never travels back through the regulator seat. The metal bowl and automatic drain suit a line that runs without daily attention.

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 GAFC400C15ASW Is Used
Machine tool coolant systems
Feed a 1/2in header on a CNC lathe or milling machine, where the 5 um element protects precision solenoid valves and the automatic drain handles condensate from frequent cycling.
Assembly line pick-and-place
Supply a multi-station pick-and-place cell with regulated air at 0.15-0.9 MPa (20-130 psi), while the lubricator keeps slide bearings and gripper mechanisms oiled.
Packaging equipment
Run a carton erector or case sealer from this unit, where the 185 cc oil bowl supports continuous operation and the metal bowl suits a washdown-adjacent area.
Is the Airtac GAFC Air Service Unit GAFC400C15ASW the Right Air-Prep Unit?
Choose the GAFC400 body when 1/2in ports match your manifold and the 100 cc condensate bowl plus 185 cc oil bowl give a practical service interval. The metal bowl is specified by the C code; the catalogue lists the same 1.0 MPa maximum and -5 to 70 C range for PC, metal and nylon, so confirm the material suits your environment. The automatic drain clears condensate without an operator, which suits wet or unattended lines. The 5 um element traps finer particles than the standard 40 um, at the cost of more frequent element service. A circular gauge is fitted, reading MPa and psi for the default PT thread. The filter-regulator and lubricator are orderable separately 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, so plan the supply pressure accordingly.
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 GAFC400C15ASW FAQ
The working pressure range is 0.15-0.9 MPa (20-130 psi), with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and must not freeze. The drain bowl holds 100 cc and the oil bowl holds 185 cc. Recommended lubricant is ISO VG 32. The unit weighs 1810 g.
The C code specifies a metal bowl, which is a build choice for the surrounding environment; the catalogue gives the same pressure and temperature limits for all bowl materials. The A code adds an automatic drain that clears condensate without an operator, which is useful for lines that run unattended or see wet supply air.
