Airtac GAFC Air Service Unit GAFC600C20AS
The AirTAC Airtac GAFC Air Service Unit GAFC600C20AS 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 GAFC600C20AS
This GAFC600C20AS is a two-piece F.R.L. combination built for heavy line duty: a filter-regulator body handles filtration and pressure setting, then a lubricator adds a metered oil mist downstream. The 3/4in port and 3430 g mass put it in the largest GAFC size class, so plan for a rigid panel or frame mount rather than tubing support.
The metal bowl holds 205 cc of condensate and the separate oil bowl 410 cc, which means fewer service visits on a busy header. It regulates from 0.15 to 0.9 MPa (20-130 psi) with a 40 um element, and the circular gauge reads in MPa and psi. The automatic drain clears water without an operator, suiting unattended or remote installations.

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 GAFC600C20AS Is Used
Machine tool header
Feed a multi-spindle machining center's pneumatic clamping and tool-change circuits with the 3/4in port and 12000 L/min plotted envelope at 0.7 MPa inlet.
Assembly line lubrication
Supply a network of air cylinders on a car assembly transfer line, where the 410 cc oil bowl keeps mist dosing consistent across many shifts.
Heavy press actuation
Run a large stamping press's safety clutch and parts ejectors, relying on the automatic drain to shed condensate from wet plant air without stopping production.
Is the Airtac GAFC Air Service Unit GAFC600C20AS the Right Air-Prep Unit?
Choose this GAFC600C20AS when your line needs the full 3/4in port and the largest bowl capacities in the GAFC range. The metal bowl is the only option on the 600 body, and the standard pressure type covers most industrial actuators; the automatic drain removes the need for manual dumping. The 40 um element suits general shop air, while the W option would fit a 5 um element for finer filtration. Thread is PT with the gauge scale in MPa and psi, and the K option adds a reverse-flow valve if required. Spare parts are the GAFR600-20 filter-regulator and GAL600-20 lubricator, both orderable separately. Max supply of 1.0 MPa leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan inlet pressure near the maximum 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 GAFC600C20AS FAQ
It operates from 0.15 to 0.9 MPa (20-130 psi) with a maximum supply of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. The drain bowl holds 205 cc and the oil bowl 410 cc. Recommended lubricant is ISO VG 32. The unit weighs 3430 g.
The GAFC600 body is offered with the metal bowl (C) only, so this is the standard build for the largest size class. The catalogue lists the same 1.0 MPa maximum pressure and -5 to 70 C temperature range for all bowl materials, so confirm the metal suits your specific environment rather than assuming extra chemical or impact resistance.
