Airtac GAFC Air Service Unit GAFC600C20ASNW
The AirTAC Airtac GAFC Air Service Unit GAFC600C20ASNW 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 3/4" ports, a 5 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAFC Air Service Unit GAFC600C20ASNW
This GAFC600C20ASNW is a two-piece F.R.L. combination built for high-flow machine headers. A filter and regulator share one body, and a lubricator mounts beside them on a T bracket, so the air is cleaned, set to pressure, then given a metered oil mist before reaching the line. The 3/4in port and 3430 g mass place it at the top of the GAFC range, sized for multi-station equipment rather than a single actuator.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), and the 5 um element traps finer particles than the standard 40 um grade. With no gauge fitted, the 1/4in gauge connection is left open for a field-installed indicator. The metal bowl is specified by the C code, and the automatic drain clears condensate from the 205 cc bowl without operator 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 GAFC600C20ASNW Is Used
Machine Header Supply
Feed a multi-station assembly machine where several pneumatic actuators draw from one 3/4in header, and the 410 cc oil bowl keeps lubrication consistent across long shifts.
High-Flow Test Rigs
Supply a hydraulic test stand's pneumatic clamping circuit, where the 5 um element prevents fine debris from reaching sensitive pressure regulators and directional valves.
Packaging Line Air Prep
Prepare air for a case packer's pneumatic cylinders and grippers, where the automatic drain removes water from the 205 cc bowl without stopping production for manual checks.
Is the Airtac GAFC Air Service Unit GAFC600C20ASNW the Right Air-Prep Unit?
Choose GAFC600 when the line demand reaches the upper end of the catalogue envelope, plotted to 12000 L/min at 0.7 MPa inlet. The metal bowl is the only option for this body, and the automatic drain suits unattended operation where condensate would otherwise accumulate. The 5 um element protects precision valves but will need service sooner than a 40 um grade, and the PT thread carries a gauge scale in MPa and psi if you add one to the 1/4in connection. The two units are orderable separately as GAFR600-20 and GAL600-20, so a damaged bowl does not force a full replacement. 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 inlet pressure carefully if you need the full output.
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 GAFC600C20ASNW FAQ
This unit operates from 0.15 to 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 is rated for -5 to 70 C and must not freeze. The drain bowl holds 205 cc and the oil bowl 410 cc, with a total weight of 3430 g. Use ISO VG 32 oil in the lubricator.
The C code specifies a metal bowl, which is the only bowl option for the GAFC600 body. The N after the port means no gauge is supplied, so the 1/4in gauge connection is left open for a field-installed indicator. The metal bowl is a build choice, and you should confirm it suits your environment since the catalogue gives no material-specific ratings.
