Airtac GAFR Adjustable Filter Regulator GAFR600C25ASW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR600C25ASW is a genuine two-in-one filter & regulator — a diversion-type water/particulate filter and a balanced pressure regulator built into ONE body. It has 1" ports, a 5 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR600C25ASW
The GAFR600C25ASW is a filter and pressure regulator combined in a single body, handling both filtration and steady pressure control without a lubricator. It uses a diversion structure to spin incoming air, separating liquid water and solid particles into the 205 cc metal drain bowl before the balanced regulator sets the outlet pressure.
This model has a 1" port, a standard pressure range of 0.15-0.9 MPa (20-130 psi), and a 5 um filter element for finer particle removal. The metal bowl and automatic drain suit demanding lines, while the included circular gauge with MPa/psi scale shows the set pressure at a glance.

The filter and the regulator are ONE body here — there is no separate GAF filter or GAR regulator part to assemble. Need lubrication downstream too? Add a lubricator by ordering the matching GAFC600-25 F.R.L. combination instead.

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 GAFR Adjustable Filter Regulator GAFR600C25ASW Is Used
Machine header supply
Feed a multi-station machine header where a 1" port and 12000 L/min envelope (at 0.7 MPa inlet) support several actuators running simultaneously from one conditioned air source.
Instrument air with 5 um filtration
Supply precision valves or instrumentation that need the finer 5 um element to keep small particles from affecting sensitive components, while the regulator holds a steady outlet pressure.
High-flow test bench
Set up a test bench requiring consistent pressure across a wide flow range, with the automatic drain managing condensate from high-humidity shop air without manual checks.
Is the Airtac GAFR Adjustable Filter Regulator GAFR600C25ASW the Right Air-Prep Unit?
Choose the GAFR600C25ASW for high-flow machine headers or multi-station lines where a 1" port and the 12000 L/min flow envelope (plotted at 0.7 MPa inlet) are needed. The metal bowl is the only option on this body, and the automatic drain handles condensate without manual attention, ideal for wet or unattended air systems. The 5 um element traps finer particles than the standard 40 um grade, though it will need more frequent service. The mounting bracket is included, the gauge is fitted with an MPa/psi scale, and the PT thread matches common local fittings. If downstream lubrication is ever required, the matching GAFC600-25 combination adds a lubricator. Note that 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan for a supply near the maximum to reach the full regulated 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
- ✓ Bracket kept or removed (J); add a lubricator = GAFC
Installation & Maintenance Notes
- check Install with the airflow arrow: IN to OUT, gauge/knob accessible.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Set pressure with the pressed-in self-locking knob; pull to adjust, press to lock.
- check Drain condensate before the 205 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1880 g unit on its bracket, not on the tubing.
This is a filter and regulator only — it delivers filtered, pressure-set air with no added oil. If a downstream tool needs lubrication, add a separate lubricator or order the GAFC600-25 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR600C25ASW FAQ
The GAFR600C25ASW is a filter & regulator with a 1" port, standard pressure range of 0.15-0.9 MPa (20-130 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), and temperature range -5 to 70 C. It has a 205 cc metal drain bowl, weighs 1880 g, uses a 5 um element, and has an automatic drain.
The GAFR600 body is available only with a metal bowl, which is the specified build for this size class. The automatic drain (A code) releases condensate without manual intervention, which suits high-flow lines or unattended operation where water buildup would otherwise require frequent draining.
