Airtac GAFC Air Service Unit GAFC600C20ASW
The AirTAC Airtac GAFC Air Service Unit GAFC600C20ASW 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 GAFC600C20ASW
This GAFC600C20ASW is a two-piece F.R.L. combination built for high-flow machine headers. The first body houses both the filter and the regulator, so air is cleaned and set to pressure in one pass before the lubricator adds a metered oil mist downstream. With a 3/4in port and a 3430 g mass, this unit belongs to the largest GAFC size class and needs a proper panel or frame mount rather than support from the tubing.
The working range is 0.15-0.9 MPa (20-130 psi), with a 5 um element trapping fine particles for sensitive downstream valves. The metal bowl holds 205 cc of condensate and the oil bowl 410 cc, so service intervals stretch far longer than on smaller bodies. An automatic drain clears water without operator attention, and the circular gauge reads in MPa and psi.

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 GAFC600C20ASW Is Used
Machine Tool Header
Feed a CNC machining center's pneumatic clamping system with regulated, lubricated air at 3/4in line size, where the 5 um element protects precision solenoid valves from fine wear particles.
Assembly Line Distribution
Supply a multi-station assembly conveyor's cylinders and actuators from one central point, using the 410 cc oil bowl to keep lubrication consistent across a long shift without frequent refills.
Heavy Press Circuit
Support a large forming press's air clutch and brake circuit, where the 205 cc condensate bowl and automatic drain handle the moisture load from high-cycling operation in a warm shop.
Is the Airtac GAFC Air Service Unit GAFC600C20ASW the Right Air-Prep Unit?
Choose the GAFC600C20ASW when your line demands high flow and infrequent maintenance. The 3/4in port feeds a machine header or multi-station line, while the 205 cc drain bowl and 410 cc oil bowl reduce how often someone must check the unit. The metal bowl is specified by the C code; the catalogue gives no impact or chemical data for bowl materials, so confirm it suits your environment. The automatic drain (A) handles wet or unattended lines, and the 5 um element (W) protects precision valves but will need more frequent service than a 40 um element. The PT thread carries a gauge scaled in MPa and psi. Spare parts are the GAFR600-20 filter-regulator and GAL600-20 lubricator, both orderable separately. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan your inlet pressure accordingly 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 GAFC600C20ASW 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. The drain bowl holds 205 cc and the oil bowl 410 cc. Recommended lubricant is ISO VG 32. The complete unit weighs 3430 g and has a 3/4in port.
The metal bowl is specified by the C code in the model number. The catalogue does not provide material-specific temperature or chemical resistance data, so confirm it fits your environment. The 5 um element (W) filters finer particles than the standard 40 um grade, which is better for precision valves but requires more frequent element replacement.
