About the Airtac GAFC Air Service Unit GAFC600C20SNWK
This GAFC600C20SNWK is an F.R.L. combination built from two units on one T-shape bracket: a GAFR filter-regulator (filter and regulator sharing one body) paired with a GAL lubricator. The 3/4in port and 3430 g mass place it in the largest GAFC size class, suited for machine headers or multi-station lines rather than individual actuators. It carries a 5 um element and operates on the standard 0.15-0.9 MPa (20-130 psi) range.
The metal bowl (205 cc condensate capacity) and separate oil bowl (410 cc) mean fewer service stops on high-volume lines. With the reverse-flow valve fitted and no gauge supplied (the 1/4in gauge connection is ready for one), this configuration suits installations where the set pressure is verified by a downstream instrument. The semi-auto drain dumps condensate each time pressure drops, while the manual drain offers on-demand operation.

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 GAFC600C20SNWK Is Used
Machine tool coolant systems
Feed a 3/4in header on a CNC lathe or machining center where the 5 um element protects coolant valves and the 410 cc oil bowl keeps way lubrication consistent across long shifts.
Multi-station assembly lines
Supply a bank of pneumatic cylinders on an automotive assembly conveyor. The 205 cc drain bowl and 12000 L/min envelope handle the condensate and flow from several stations without frequent attention.
Packaging film tension control
Regulate air for web-tension brakes on a packaging line where the 5 um element prevents clogging in fine orifices and the metal bowl suits a plant washdown environment.
Is the Airtac GAFC Air Service Unit GAFC600C20SNWK the Right Air-Prep Unit?
This GAFC600 is the top of the GAFC range, with a 3/4in port and a flow curve plotted to 12000 L/min at 0.7 MPa inlet - roughly double the GAFC500's 7000 L/min envelope. The metal bowl is the only option for this body, and the standard pressure type is the only choice; there is no lower-pressure variant at this size. The 5 um element traps finer particles than the standard 40 um grade, which suits precision valves but requires more frequent element service. The semi-auto plus manual drain pair covers both automatic dumping on pressure drop and manual intervention when needed. No gauge is fitted, so the 1/4in gauge connection must be used if a local readout is required. The reverse-flow valve is included, and the PT thread with MPa/psi gauge scale matches standard local fittings. Spare parts are orderable as GAFR600-20 and GAL600-20. With a 1.0 MPa max supply, there is about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan the supply pressure carefully if running near the ceiling.
Quick checklist
- ✓ Body size for your peak flow (3/4" 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 GAFR600-20 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC600C20SNWK 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). Operating temperature is -5 to 70 C and the recommended lubricant is ISO VG 32. The drain bowl holds 205 cc and the oil bowl 410 cc. The unit weighs 3430 g and has a 3/4in port.
The C code specifies a metal bowl, which is the only bowl option for the GAFC600 body. The N after the port code means no gauge is supplied; the 1/4in gauge connection is left open for a gauge to be added if needed. The catalogue lists no performance difference between bowl materials, so the metal bowl is a build choice rather than a specification upgrade.
