About the Airtac GAFC Air Service Unit GAFC600C20S
This GAFC600C20S is an F.R.L. combination where the filter and regulator share one body, paired with a lubricator on a T-bracket. The 3/4in port and 3430 g mass place it as the largest stocked unit, feeding high-demand machine headers or multi-station lines.
Air enters the first body where solids and moisture drop out and pressure is set to 0.15-0.9 MPa (20-130 psi), then the lubricator adds a metered oil mist downstream. The 40 um element handles standard shop air, while the metal bowl and dual drains suit continuous industrial duty.

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 GAFC600C20S Is Used
Machine tool coolant systems
Feed a 3/4in header supplying coolant valves and actuators on CNC lathes, where the 205 cc condensate bowl reduces maintenance stops between shifts.
Multi-station assembly lines
Power pneumatic clamps and pushers across a 12-station pallet line, using the 410 cc oil bowl to keep lubricated cylinders moving without frequent refills.
Injection molding press circuits
Supply regulated air to mold clamp cylinders and ejector pins, where the 0.15-0.9 MPa range covers typical setpoints and the metal bowl suits warm shop environments.
Is the Airtac GAFC Air Service Unit GAFC600C20S the Right Air-Prep Unit?
Choose this GAFC600C20S when your line needs the full 3/4in port and the 12000 L/min flow envelope plotted at 0.7 MPa inlet. The metal bowl is specified by the C code, and the semi-auto drain dumps on pressure drop while the manual drain offers on-demand control. The circular gauge reads in MPa/psi for the PT thread, and the 40 um element balances filtration with service life. For oil-free downstream air, omit the lubricator and select a plain GAFR filter-regulator instead. Spares are orderable as GAFR600-20 and GAL600-20. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan inlet pressure carefully if you need the full regulated 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 GAFC600C20S 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). Operating temperature is -5 to 70 C. The drain bowl holds 205 cc, the oil bowl holds 410 cc, and the unit weighs 3430 g. Recommended lubricant is ISO VG 32.
The C code specifies a metal bowl, which is the only option offered for the GAFC600 body. The catalogue lists the same 1.0 MPa max pressure and -5 to 70 C range for all bowl materials, so confirm the metal suits your specific environment rather than assuming added toughness.
