Airtac GAFR Adjustable Filter Regulator GAFR30008SK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30008SK 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.

About the Airtac GAFR Adjustable Filter Regulator GAFR30008SK
The GAFR30008SK is a filter and regulator combined in a single body, handling both filtration and pressure control without needing separate units. It serves a 1/4in port with a 40 um element and a working range of 0.15-0.9 MPa (20-130 psi), and it includes a reverse-flow valve.
This model weighs 500 g and has a 60 cc condensate bowl, which determines how often draining is needed. The diversion structure spins incoming air to separate liquid water and solid particles, while the balanced regulator holds the set pressure steady as supply varies. No lubricator is present, as this unit only filters and regulates.

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.

Where the Airtac GAFR Adjustable Filter Regulator GAFR30008SK Is Used
Single jig clamping
Feed a 1/4in line to a bench-mounted jig or fixture where a steady 0.15-0.9 MPa holds parts during drilling or assembly. The 40 um element protects the actuating cylinder from abrasive grit.
Prototype test rig
Use on a lab bench or test stand with a single pneumatic actuator or valve manifold. The included gauge lets you verify set pressure at a glance, and the 60 cc bowl handles condensate from short test cycles.
Maintenance air station
Mount near a workbench to supply filtered, regulated air for blow-off guns or small hand tools. The semi-auto drain purges water automatically while allowing a manual check during routine servicing.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30008SK the Right Air-Prep Unit?
Choose the GAFR300 body for 1/4in ports where a 500 g unit with a 60 cc bowl fits the layout; step up to a GAFR400 for a 100 cc bowl and a flow envelope plotted to 7000 L/min at 0.7 MPa inlet if the line demands more capacity. The PC bowl suits general shop air, while the included bracket simplifies mounting, and the semi-auto plus manual drain covers both automatic purging and manual override. The 40 um element handles standard particulate, and the fitted gauge reads in MPa/psi per the PT thread. If oil is needed downstream, order the matching GAFC300-08 combination instead of expecting this unit to lubricate. Max supply of 1.0 MPa leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan inlet pressure near the maximum for full output.
Quick checklist
- ✓ Body size for your peak flow (1/4" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: PC (blank), Metal (C), Nylon (N)
- ✓ 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 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 500 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 GAFC300-08 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR30008SK FAQ
The GAFR30008SK is a filter & regulator with a 1/4in port, a pressure range of 0.15-0.9 MPa (20-130 psi), a maximum pressure of 1.0 MPa (145 psi), and a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C, has a 60 cc drain bowl, and weighs 500 g. The element is 40 um, and the unit includes a semi-auto plus manual drain.
The K code indicates a reverse-flow (reflux) valve is fitted to the GAFR30008SK. It is an ordering difference from models without the K suffix. The catalogue does not detail its function in our data, so we cannot explain its operation. If you need to know how it works, please confirm with the full AirTAC datasheet.
