Airtac GAFC Air Service Unit GAFC600C25SNW
The AirTAC Airtac GAFC Air Service Unit GAFC600C25SNW is a genuine two-piece F.R.L. combination — a GA-series filter & regulator and a lubricator pre-assembled on one T-shape bracket with quick mounting clamps. It has 1" ports, a 5 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAFC Air Service Unit GAFC600C25SNW
The GAFC600C25SNW is a two-piece F.R.L. combination built for high-capacity lines. A filter and regulator share one body, and a lubricator mounts on the same T-bracket, so a 1in port line gets all three functions without a third housing. The 5 um element traps fine particles before air reaches the regulator seat, and the metal bowl holds 205 cc of condensate.
This standard-type unit regulates from 0.15 to 0.9 MPa (20-130 psi) with a 1.0 MPa (145 psi) maximum supply. The lubricator adds a metered ISO VG 32 oil mist after pressure is set, so oil never travels back through the regulator. At 3430 g, this is the heaviest GAFC body and needs a proper frame or panel mount, not support from the tubing.

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 GAFC600C25SNW Is Used
Machine tool coolant systems
Feed a 1in header serving multiple CNC spindles where consistent 0.15-0.9 MPa regulation and fine 5 um filtration protect servo valves from wear.
High-speed assembly lines
Supply a multi-station pallet conveyor with lubricated air for cylinders and grippers, relying on the 205 cc bowl to handle condensate between shifts.
Packaging film tension controls
Maintain precise pressure for pneumatic brakes on film winders, where the 5 um element keeps particles from clogging sensitive regulator orifices.
Is the Airtac GAFC Air Service Unit GAFC600C25SNW the Right Air-Prep Unit?
Choose the GAFC600C25SNW when a 1in port machine header needs filtered, regulated, lubricated air at flows up to the catalogue's plotted 12000 L/min envelope at 0.7 MPa inlet. The metal bowl is specified by the C code, and the semi-auto drain dumps condensate on each pressure drop while the manual drain offers on-demand release. The 5 um element suits precision valves or instrument air but requires more frequent service than the standard 40 um grade. No gauge is supplied with the N code, so plan to add one at the 1/4in gauge connection if operators need to read set pressure. The PT thread carries an MPa/psi gauge scale. Spares are the GAFR600-25 filter-regulator and GAL600-25 lubricator, both orderable separately. With 1.0 MPa max supply, there is only about 0.1 MPa above the 0.9 MPa top of the regulated range, so set the supply near maximum if you need the full output.
Quick checklist
- ✓ Body size for your peak flow (1" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: Metal (C) only
- ✓ 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 205 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 3430 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 GAFR600-25 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC600C25SNW FAQ
This F.R.L. combination operates from 0.15 to 0.9 MPa (20-130 psi) with a maximum supply of 1.0 MPa (145 psi) and 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 205 cc drain bowl and a 410 cc oil bowl, and weighs 3430 g. The 5 um element is fitted, and the gauge connection is 1/4in.
The C code specifies a metal bowl for this model. The catalogue lists the same 1.0 MPa maximum pressure and -5 to 70 C temperature range for all bowl materials, so the choice is a build preference rather than a performance upgrade. Confirm the metal bowl suits your specific environment before ordering, as no material-specific chemical or impact data is published.
