About the Airtac GAFC Air Service Unit GAFC600C25SK
This GAFC600C25SK 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 before it reaches the lubricator, which adds a controlled oil mist last. With a 1in port and a 3430 g mass, this unit belongs to the largest size class in the GAFC range 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 40 um element and a circular gauge fitted that reads in MPa/psi for the PT thread. The metal bowl is specified by the C code, and the semi-auto drain dumps condensate on each pressure drop while the manual drain offers on-demand emptying. The catalogue flow curve is plotted to 12000 L/min at 0.7 MPa inlet, which serves as a sizing envelope rather than a rated capacity.

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 GAFC600C25SK Is Used
Machine Header Supply
Feed a multi-station assembly machine header where the 1in port and 12000 L/min envelope at 0.7 MPa inlet support several actuators running from one distribution point.
Large Conveyor System
Protect and lubricate the air cylinders on a long conveyor line, where the 205 cc condensate bowl and 410 cc oil bowl reduce the frequency of maintenance rounds.
Heavy Stamping Press
Condition the air supply for a stamping press clutch and feed mechanism, where the metal bowl and the 3430 g mass suit a fixed installation on a machine frame.
Is the Airtac GAFC Air Service Unit GAFC600C25SK the Right Air-Prep Unit?
Choose this GAFC600C25SK when the line demands the 1in port and the 12000 L/min envelope at 0.7 MPa inlet. The metal bowl is a build choice, and the shared specification of 1.0 MPa max pressure and -5 to 70 C applies regardless of material, so confirm the metal suits your surroundings. The semi-auto plus manual drain pair suits attended stations, while the reverse-flow valve fitted here is an ordering difference shown as a separate symbol in the catalogue. The 40 um element handles general shop air, and the PT thread carries a gauge scale in MPa/psi. If the line must stay oil-free, choose a plain GAFR filter-regulator instead, since this set adds oil mist. Spare units are orderable as GAFR600-25 and GAL600-25. The 1.0 MPa max supply leaves 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 (1" 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 GAFR600-25 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC600C25SK FAQ
The GAFC600C25SK operates from 0.15 to 0.9 MPa (20-130 psi) with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C and the recommended lubricant is ISO VG 32. The drain bowl holds 205 cc and the oil bowl holds 410 cc, with a total weight of 3430 g. The element grade is 40 um.
The C code specifies a metal bowl, which is a build choice for this model; the catalogue does not publish impact or chemical resistance data for bowl materials, so confirm it suits your environment. The K code means the reverse-flow valve is fitted, and the catalogue shows it as a separate pneumatic symbol. The semi-auto drain dumps on pressure drop while the manual drain works on demand.
