Airtac GAFC Air Service Unit GAFC600C25SNWK
The AirTAC Airtac GAFC Air Service Unit GAFC600C25SNWK 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 1" ports, a 5 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAFC Air Service Unit GAFC600C25SNWK
This AirTAC GAFC600C25SNWK is a two-piece F.R.L. combination built for a 1in air line. The first body combines a filter and a regulator, so solids and moisture drop out and pressure is set before the air moves on. The second body is the lubricator, which adds a controlled oil mist last, downstream of the regulator seat.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 5 um element fitted to trap fine particles. The metal bowl holds 205 cc of condensate, while the oil bowl holds 410 cc, and the complete unit weighs 3430 g. No gauge is supplied, so the set pressure cannot be read without adding one to the 1/4in gauge connection.

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 GAFC600C25SNWK Is Used
Machine tool coolant systems
Feed a 1in header on a CNC machining center, where the 5 um element protects precision solenoid valves from fine abrasive dust.
Multi-station assembly lines
Supply a bank of pneumatic actuators on an automotive assembly line, where the 410 cc oil bowl keeps lubrication consistent across many shifts.
Packaging film tensioning
Run the web tensioning cylinders on a high-speed packaging machine, where stable regulated pressure at 0.15-0.9 MPa holds film alignment.
Is the Airtac GAFC Air Service Unit GAFC600C25SNWK the Right Air-Prep Unit?
Choose this GAFC600 when a 1in line feeds a machine header or a multi-station line. The metal bowl is specified by the C code, and the shared specification of 1.0 MPa max and -5 to 70 C applies regardless of material, so confirm the metal suits your environment. The semi-auto drain dumps condensate on each pressure drop, with a manual drain for on-demand use, and the 5 um element suits precision valves but needs more frequent service than a 40 um element. The reverse-flow (reflux) valve is fitted, and the PT thread comes with a gauge scale in MPa and psi if a gauge is added later. The two units are orderable separately as GAFR600-25 and GAL600-25. With a 1.0 MPa max supply, there is only about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan the supply pressure carefully if you need the full output.
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 GAFC600C25SNWK FAQ
The working pressure range is 0.15-0.9 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, the oil bowl holds 410 cc, and the unit weighs 3430 g.
The N after the port code means no gauge is supplied with this unit. The gauge connection on the GAFC600 body is 1/4in, so you can add a compatible gauge later if you need to read the set pressure. The PT thread version uses a gauge scale graduated in MPa and psi.
