Airtac GAFC Air Service Unit GAFC600C20SN
The AirTAC Airtac GAFC Air Service Unit GAFC600C20SN 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 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAFC Air Service Unit GAFC600C20SN
The GAFC600C20SN is a two-piece F.R.L. combination built for high-capacity lines. The first body combines a filter and regulator, cleaning the air and setting pressure before the lubricator adds a controlled oil mist downstream. With a 3/4" port and a 3430 g mass, this unit belongs to the largest GAFC size class and needs a proper panel or frame mount, not support from the tubing.
This standard-type model regulates from 0.15 to 0.9 MPa (20-130 psi) with a 40 um element. The metal bowl is specified by the C code, and the unit ships with both semi-auto and manual drains. No gauge is fitted, so the 1/4" gauge connection is the point to add one if the set pressure needs to be read locally.

Constituent units, orderable separately as spares: GAFR600-20 filter & regulator, GAL600-20 lubricator — both share this body and port. A GAFC has two units, not three: the filter and the regulator are one body.

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 GAFC600C20SN Is Used
Machine Tool Header
Feed a 3/4" header supplying multiple actuators on a CNC machining center, where the 205 cc condensate bowl and 410 cc oil bowl extend time between service checks.
Multi-Station Assembly Line
Supply a bank of pneumatic cylinders on an automotive assembly conveyor, using the 12000 L/min envelope at 0.7 MPa inlet to size for simultaneous motion.
Heavy-Duty Press Station
Protect a stamping press clutch and brake circuit with filtered, regulated air and metered lubrication, where the metal bowl suits a shop floor environment.
Is the Airtac GAFC Air Service Unit GAFC600C20SN the Right Air-Prep Unit?
Choose the GAFC600 for a machine header or multi-station line where a 3/4" port and 205 cc condensate bowl reduce how often someone must attend the unit. The metal bowl is a build choice; the catalogue gives no impact or chemical data, so confirm it suits your surroundings. The semi-auto drain dumps on each pressure drop while the manual drain offers on-demand operation. The 40 um element handles general shop air, and the PT thread carries a MPa/psi gauge scale if you add a gauge later. The two units are orderable separately as GAFR600-20 and GAL600-20. With a 1.0 MPa max supply, you have about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan the supply pressure accordingly.
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 GAFC600C20SN FAQ
The GAFC600C20SN 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). The temperature range is -5 to 70 C. It has a 205 cc drain bowl and a 410 cc oil bowl, weighs 3430 g, and uses ISO VG 32 lubricant.
The N after the port code means no gauge is supplied. The GAFC600 body has a 1/4" gauge connection, so you can add a circular gauge there to read the set pressure. The PT thread means any gauge you add should have an MPa/psi scale.
