About the Airtac GAFC Air Service Unit GAFC600C25SN
This AirTAC GAFC600C25SN is a two-piece F.R.L. combination built for high-flow lines. The first body houses both the filter and the regulator, so air is cleaned and set to pressure before it moves on; the second body is the lubricator, which adds a metered oil mist last. 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 rather than support from the tubing.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), and the 40 um element handles general workshop air. This model has no gauge fitted, so the gauge connection on the body is 1/4in if you add one later. The metal bowls hold 205 cc for condensate and 410 cc for oil, which means fewer visits to top up or drain compared with smaller bodies in the series.

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 GAFC600C25SN Is Used
Machine tool coolant systems
Feed a central header for CNC coolant pumps and valve manifolds. The 1in port and 410 cc oil bowl keep multiple lubricated actuators running without frequent refills.
High-capacity assembly lines
Supply a multi-station conveyor with filtered, regulated, and lubricated air. The 205 cc drain bowl handles condensate from long pipe runs, and the metal bowls suit industrial environments.
Large press and stamping equipment
Operate heavy pneumatic clutches and brakes on stamping presses. The 0.15-0.9 MPa range covers typical press circuits, while the 12000 L/min plotted envelope at 0.7 MPa inlet shows the flow capacity for big cylinders.
Is the Airtac GAFC Air Service Unit GAFC600C25SN the Right Air-Prep Unit?
Choose the GAFC600 when your line demands high flow and large reservoirs. The 1in port suits machine headers or multi-station lines, and the metal bowls are the only option for this body size. The semi-auto drain dumps condensate when pressure drops, while the manual drain gives you on-demand control; both are fitted here. The standard type regulates from 0.15 to 0.9 MPa (20-130 psi), and the PT thread comes with a gauge scale in MPa and psi if you fit a gauge later. The 40 um element is the default; step to the 5 um version if you need finer filtration for sensitive valves. The lubricator is meant to carry oil, so if your process needs oil-free air, choose a plain GAFR filter-regulator instead. Spare parts are the GAFR600-25 filter & regulator and the GAL600-25 lubricator, both orderable separately. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan your inlet pressure carefully if you intend to run near the upper limit.
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 GAFC600C25SN FAQ
The GAFC600C25SN is a standard-type F.R.L. combination with a 1in port. It regulates from 0.15-0.9 MPa (20-130 psi), with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and uses ISO VG 32 lubricant. The metal drain bowl holds 205 cc, the oil bowl holds 410 cc, and the unit weighs 3430 g. The 40 um element filters the air, and the PT thread has a gauge scale in MPa and psi.
The N in the code means no gauge is supplied with this unit. The gauge connection on the GAFC600 body is 1/4in, so you can fit a compatible gauge if you need to read the outlet pressure. Without one, you cannot see the set pressure directly on the unit, so plan to add a gauge if your operators need to verify the setting.
