About the Airtac GAFC Air Service Unit GAFC600C25SWK
This GAFC600C25SWK is a two-piece F.R.L. combination built for heavy plant air. The first body combines a filter and a regulator, so the 5 um element removes solids and moisture before the pressure is set, and the second body is the lubricator that meters oil mist into the cleaned, regulated air. The 1in port and 3430 g mass put it at the top of the GAFC range, sized for machine headers and multi-station lines rather than single actuators.
The metal bowl is the only bowl option on the GAFC600, and the standard pressure range is 0.15-0.9 MPa (20-130 psi). The 205 cc drain bowl and 410 cc oil bowl are the largest in the series, so service intervals are long. A circular gauge is fitted with an MPa/psi scale for the PT thread, and the reverse-flow valve is included as an ordering option.

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 GAFC600C25SWK Is Used
Machine Tool Header
Feed a CNC lathe or machining center header with 1in piping, where the 5 um element protects spindle air bearings and the 410 cc oil bowl keeps way lubrication topped up between shifts.
Multi-Station Assembly Line
Supply a bank of pneumatic actuators on an automotive assembly line, where the 205 cc drain bowl handles condensate from a long wet-air run and the metal bowl suits the plant floor environment.
Packaging Machine Air Prep
Prepare air for a high-speed packaging machine with multiple cylinders and valves, where the 12000 L/min plotted flow envelope at 0.7 MPa inlet supports the peak demand of a full cycle.
Is the Airtac GAFC Air Service Unit GAFC600C25SWK the Right Air-Prep Unit?
Choose the GAFC600 when a 1in port and the largest bowl capacities in the series are needed for a high-flow header. The metal bowl is standard on this body, and the 5 um element traps finer particles than the 40 um standard, which suits precision valves but requires more frequent element service. The semi-auto drain dumps condensate on pressure drop, with a manual drain for on-demand use, and the PT thread carries an MPa/psi gauge scale. The reverse-flow valve is fitted, and the gauge is included. Spare parts are the GAFR600-25 filter & regulator and the GAL600-25 lubricator, both orderable separately. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan the supply pressure near 1.0 MPa if you need the full regulated 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 GAFC600C25SWK 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). The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. The drain bowl holds 205 cc, the oil bowl holds 410 cc, and the unit weighs 3430 g. The 5 um element is fitted, and the thread is PT with an MPa/psi gauge scale.
The K code specifies that the reverse-flow (reflux) valve is fitted to this GAFC600C25SWK. The catalogue shows it as a separate pneumatic symbol in the circuit. It is an ordering difference from the standard GAFC600, and the valve is included as part of the assembly.
