About the Airtac GAFC Air Service Unit GAFC600C20ASN
This AirTAC GAFC600C20ASN is a two-piece F.R.L. combination built for heavy plant air. A single body houses both the filter and the regulator, so air is cleaned and set to pressure before it reaches the lubricator, which adds a metered oil mist as the final step. The 3/4in port and 3430 g mass place it at the top of the GAFC range, sized for machine headers and multi-station lines rather than individual actuators.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 40 um element trapping solids and water. The metal bowl is specified by the C code, and the automatic drain clears condensate without operator attention. No gauge is supplied with this model, but the 1/4in gauge connection allows one to be added if the set pressure needs to be read locally.

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 GAFC600C20ASN Is Used
Machine Tool Header
Feed a CNC lathe or machining center's air header, where the 3/4in port and 12000 L/min envelope at 0.7 MPa inlet support multiple cylinders and tool changers.
Multi-Station Assembly Line
Supply a palletized assembly line with several pneumatic stations, using the large 410 cc oil bowl to maintain lubrication across many actuators between refills.
Heavy Press Automation
Prepare air for a stamping press or injection molder's safety circuits, where the automatic drain keeps condensate out of sensitive valves without manual checks.
Is the Airtac GAFC Air Service Unit GAFC600C20ASN the Right Air-Prep Unit?
Choose the GAFC600 when a single unit must feed a large machine header or several stations. The 205 cc condensate bowl and 410 cc oil bowl are the largest in the series, so service intervals are long. The A code specifies an automatic drain, which suits unattended operation or wet supply lines. The metal bowl is a build choice; confirm it suits your environment, as the catalogue gives no material-specific ratings. The N code means no gauge is fitted, so plan to add one via the 1/4in connection if operators need to verify pressure. The PT thread suits installations using standard pipe threads. Spare parts are the GAFR600-20 filter-regulator and the GAL600-20 lubricator, both orderable separately. With a 1.0 MPa max supply, there is about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range.
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 GAFC600C20ASN FAQ
This F.R.L. combination operates from 0.15 to 0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. The temperature range is -5 to 70 C, and it must not freeze. It has a 205 cc condensate bowl and a 410 cc oil bowl, weighs 3430 g, and uses ISO VG 32 lubricant. The 3/4in port and 40 um element are standard for this body.
The C code specifies a metal bowl, which is the only option for the GAFC600 body. The N code after the port means no gauge is supplied; the 1/4in gauge connection is available if you need to add one. The automatic drain, indicated by A, clears condensate without an operator, making this configuration suitable for continuous or remote operation.
