Airtac GAFR Adjustable Filter Regulator GAFR600C25ASK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR600C25ASK 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 40 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 GAFR600C25ASK
The GAFR600C25ASK is a filter and regulator combined into a single body, handling both filtration and pressure control in one compact unit. This model features a 1 inch port, a metal bowl, and a standard pressure range of 0.15-0.9 MPa (20-130 psi), with a 40 um filtering element.
Its 205 cc condensate bowl and 1880 g weight place it as the largest unit in the GAFR series, designed for high-flow applications. The automatic drain ensures condensate is expelled without manual intervention, while the circular gauge with MPa/psi scale provides clear pressure readout.

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 GAFR600C25ASK Is Used
Machine Header Supply
Feed a multi-station machine header with clean, regulated air at high volume. The 1 inch port and 12000 L/min flow envelope support multiple actuators operating simultaneously.
Large Conveyor System
Regulate air for a long conveyor line with numerous pneumatic cylinders. The automatic drain handles condensate from wet supply lines, reducing maintenance stops.
Central Plant Air Prep
Serve as a central point for filtering and pressure control before distribution to multiple workstations. The metal bowl and large capacity suit permanent industrial installations.
Is the Airtac GAFR Adjustable Filter Regulator GAFR600C25ASK the Right Air-Prep Unit?
Choose the GAFR600 body for the highest flow capacity in the series, with a flow curve plotted to 12000 L/min at 0.7 MPa inlet. This model comes with a metal bowl (C), which is the only option for this body size, and an automatic drain (A) for unattended operation. The standard pressure type (S) covers 0.15-0.9 MPa, and the included mounting bracket simplifies installation. A circular gauge is fitted, reading in MPa/psi due to the PT thread. The 40 um element handles general-purpose filtration, and the reverse-flow (reflux) valve (K) is attached. For lines needing lubrication downstream, 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.
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 GAFR600C25ASK FAQ
The GAFR600C25ASK operates in a pressure range of 0.15-0.9 MPa (20-130 psi), with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It is rated for temperatures from -5 to 70 C. The unit has a 205 cc drain bowl and weighs 1880 g.
The GAFR600C25ASK includes a reverse-flow (reflux) valve, indicated by the K in the model code. This is an ordering difference from models without the valve. For details on its function, please refer to the official AirTAC catalogue.
