Airtac GAFR Adjustable Filter Regulator GAFR600C25SNWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR600C25SNWK 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 GAFR600C25SNWK
The GAFR600C25SNWK is a filter and regulator combined into a single body, handling both air cleaning and pressure control in one compact unit. It has a 1 inch port and a metal bowl, with a working pressure range of 0.15-0.9 MPa (20-130 psi), and uses a 5 um filter element for fine particle removal.
This model weighs 1880 g and features a 205 cc drain bowl, making it suitable for high-flow applications. The unit is fitted with a reverse-flow valve and includes a mounting bracket, but does not come with a gauge, so the 1/4 inch gauge connection can be used to add one if needed.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. No gauge is supplied with this model — the gauge connection on a GAFR600 is 1/4" if you add one. This unit filters and regulates only; it does not add lubrication.

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 GAFR600C25SNWK Is Used
Machine Header Supply
Feed a main air header for a multi-station assembly machine, where the 1 inch port and high flow envelope support multiple actuators operating simultaneously.
Instrument Air Pre-Filter
Use the 5 um element to protect sensitive pneumatic controls and precision valves from fine particulate matter in a manufacturing line.
Large Conveyor System
Regulate air pressure for a long conveyor system with many pneumatic stops and guides, benefiting from the large 205 cc drain bowl to reduce maintenance frequency.
Is the Airtac GAFR Adjustable Filter Regulator GAFR600C25SNWK the Right Air-Prep Unit?
Choose the GAFR600 body when you need a large flow capacity, as its flow curve is plotted to 12000 L/min at 0.7 MPa inlet, significantly higher than the GAFR500's 8000 L/min envelope. The metal bowl is the only option for this body size, and the standard pressure type (S) provides a 0.15-0.9 MPa range, while the 5 um element suits applications requiring finer filtration. This unit includes the mounting bracket, has a semi-auto plus manual drain, and uses PT threads. The reverse-flow valve is fitted as an ordering difference, and if you need lubrication downstream, the matching GAFC600-25 combination adds a lubricator. For sizing, 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 GAFR600C25SNWK FAQ
The GAFR600C25SNWK 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). Its temperature range is -5 to 70 C. It has a 205 cc drain bowl and weighs 1880 g, with a 1 inch port.
The K code indicates a reverse-flow (reflux) valve is fitted, which is an ordering difference. The N code means no gauge is supplied, so the set pressure cannot be read directly; you would need to add a gauge to the 1/4 inch connection to monitor outlet pressure.
