The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30008ASNK 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 1/4" 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.
The GAFR30008ASNK is a filter and regulator combined into a single body, so incoming air is first spun to separate liquid water and solid particles, then regulated to a steady outlet pressure. This model has a 1/4in port, a 40 um element, and a working range of 0.15-0.9 MPa (20-130 psi).
With a 500 g mass and a 60 cc condensate bowl, this unit is sized for light machine circuits. The automatic drain clears collected water without manual attention, and the pressed-in self-locking knob keeps the set pressure stable against vibration.

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 GAFR300 is 1/8" 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 GAFC300-08 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 single pneumatic actuator or a small indexing fixture with clean, regulated air at a stable pressure, thanks to the balanced regulator holding the setpoint as supply varies.
Mount this 500 g unit on a test bench or light assembly rig where a compact filter-regulator with automatic draining keeps the air clean without frequent manual checks.
Use it ahead of a small cylinder or air tool on a packaging or assembly machine, where the 40 um element protects downstream components and the 60 cc bowl handles typical condensate loads.
Choose the GAFR300 body when your line is 1/4in and you need a 60 cc drain bowl; step up to the GAFR400 (3/8in or 1/2in, 100 cc bowl, 880 g) if you need more condensate capacity. The PC bowl is the standard build, the automatic drain suits wet or unattended lines, and the included bracket simplifies panel mounting. No gauge is fitted, so the 1/8in gauge connection is available if you add one later. The PT thread carries an MPa/psi scale, and the reverse-flow (reflux) valve is fitted as an ordering difference. If oil is needed downstream, order the matching GAFC300-08 combination instead. 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 GAFC300-08 combination; do not expect an oil mist from this unit.
The GAFR30008ASNK is a filter and regulator with a 1/4in port, working pressure 0.15-0.9 MPa (20-130 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), temperature range -5 to 70 C, 40 um element, 60 cc drain bowl, and 500 g weight. It has an automatic drain and no gauge.
The K code indicates the reverse-flow (reflux) valve is fitted as an ordering difference. The catalogue defers its function to a separate page, so treat it as a specified option for your application rather than a standard feature.
