The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR600C25ASNWK 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.
The GAFR600C25ASNWK 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 5 um element, with a working pressure range of 0.15-0.9 MPa (20-130 psi).
This unit weighs 1880 g and has a 205 cc condensate bowl, making it the largest in the GAFR series. The balanced regulator mechanism holds the outlet pressure steady even when supply pressure varies, and the pressed-in self-locking knob resists drift from vibration. The diversion structure spins the incoming air to separate liquid water and trap solid particles before regulation.

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.

Feed a multi-station machine header with a single 1 inch line, providing filtered and regulated air to several actuators and valves from one central point.
Supply a long conveyor system with consistent pressure, where the 12000 L/min plotted flow envelope at 0.7 MPa inlet supports multiple pneumatic cylinders along the line.
Deliver 5 um filtered air to a bank of precision instruments or flow controllers, where finer filtration protects sensitive components from wear.
Choose the GAFR600 when you need a 1 inch port and maximum condensate capacity. The 205 cc drain bowl holds about 8 times the condensate of the GAFR200's 25 cc bowl, meaning far fewer drain interventions on a busy line. The metal bowl is the only option for this body size, and the automatic drain (A) handles condensate without manual attention. The 5 um element traps finer particles than the standard 40 um grade, which suits precision valves or instrument air but requires more frequent element service. The mounting bracket is included, and the no-gauge (N) option means the 1/4 inch gauge connection is available if you add one later. The PT thread with MPa/psi scale is standard, and the reverse-flow (reflux) valve is fitted as an ordering difference. If your line needs oil downstream, order the matching GAFC600-25 combination instead. A 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range.
Quick checklist
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.
The GAFR600C25ASNWK is a filter and regulator with a 1 inch port, working pressure range of 0.15-0.9 MPa (20-130 psi), maximum pressure of 1.0 MPa (145 psi), and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. It has a 205 cc drain bowl and weighs 1880 g, with a 5 um element and automatic drain.
The K code indicates a reverse-flow (reflux) valve is fitted to this unit. It is an ordering difference from the standard version. The catalogue defers the detailed function of this valve to a separate page, so consult the full datasheet for its operational specifics.
