Airtac GAFC Air Service Unit GAFC600C25ASNK
The AirTAC Airtac GAFC Air Service Unit GAFC600C25ASNK 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 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAFC Air Service Unit GAFC600C25ASNK
This GAFC600C25ASNK 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 in one pass; the second body is the lubricator that adds a metered oil mist downstream. With a 1in 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.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 40 um element and an automatic drain that clears condensate without an operator. The metal bowl holds 205 cc of condensate and the oil bowl holds 410 cc, so service intervals are long for a machine header. No gauge is supplied; the 1/4in gauge connection is there if you add one later. A reverse-flow valve is fitted, and the catalogue shows it as a separate pneumatic symbol.

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 GAFC600C25ASNK Is Used
Machine Header Supply
Feed a multi-station assembly machine header where several actuators draw air simultaneously. The 1in port and 12000 L/min flow envelope at 0.7 MPa inlet support high simultaneous demand.
CNC Coolant System
Supply a CNC machining center's pneumatic clamping and tool-change system. The automatic drain keeps condensate out of precision valves, and the 410 cc oil bowl keeps lubrication consistent across shifts.
Heavy Conveyor Line
Run a long conveyor line with multiple pneumatic stops and diverters. The 205 cc condensate bowl and 410 cc oil bowl reduce maintenance frequency compared to smaller F.R.L. units.
Is the Airtac GAFC Air Service Unit GAFC600C25ASNK the Right Air-Prep Unit?
Choose this GAFC600C25ASNK when you need a 1in F.R.L. combination for a multi-station line or a machine header. The metal bowl is specified by the C code; the common specification of 1.0 MPa max and -5 to 70 C applies to all bowl materials, so confirm the metal suits your surroundings. The automatic drain (A) removes condensate without operator attention, ideal for wet or unattended lines. The 40 um element is the standard grade; choose the W version if you need 5 um filtration for finer particles. The PT thread comes with a gauge scale in MPa/psi, but this model has no gauge fitted, so plan to read pressure elsewhere or add one to the 1/4in connection. The reverse-flow valve is fitted per the K code. The two units are orderable separately as GAFR600-25 and GAL600-25. If the line must stay oil-free, omit the lubricator and choose a plain GAFR filter-regulator instead. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan a supply near 1.0 MPa if you need 0.9 MPa out.
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 GAFC600C25ASNK FAQ
The GAFC600C25ASNK operates at 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). 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. The unit weighs 3430 g and has a 1in port.
The N after the port code means no gauge is supplied with this GAFC600C25ASNK. The gauge connection is 1/4in, so you can add a circular gauge later if needed. Without a gauge, the set pressure cannot be read directly on the unit, so plan to measure it elsewhere in the system or add one to the connection.
