Airtac GAFR Adjustable Filter Regulator GAFR30008SJWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30008SJWK 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 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 GAFR30008SJWK
The GAFR30008SJWK is a filter and pressure regulator combined into a single body, so incoming air is first spun to separate liquid water and solid particles, then set to a steady outlet pressure by a balanced regulator. This 1/4in unit works across 0.15-0.9 MPa (20-130 psi) and uses a 5 um element to trap fine particles for sensitive equipment.
The pressed-in self-locking knob resists set-pressure drift from vibration, keeping the outlet stable on moving machinery. With a 60 cc condensate bowl and 500 g mass, this size class suits panel mounting rather than support from the tubing alone.

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 GAFR30008SJWK Is Used
Precision valve control
Feed a single precision pneumatic valve or small actuator on a benchtop assembly station, where the 5 um element protects fine internal passages from abrasive wear.
Vibration-prone equipment
Mount on a small press or indexing table where machine vibration could drift a standard regulator; the self-locking knob holds the set pressure steady during repeated cycles.
Compact machine build
Integrate into a tight control cabinet or rail where space is limited; the single-body design replaces separate filter and regulator units, reducing joints and rail width.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30008SJWK the Right Air-Prep Unit?
Choose the GAFR300 body for 1/4in ports with a 3500 L/min flow curve plotted at 0.7 MPa inlet, a step up from the GAFR200's 2000 L/min envelope for small jigs. The PC bowl is the standard build, while the 5 um element (W) traps finer particles than the 40 um default, at the cost of more frequent service. This model has both semi-auto and manual drains, the PT thread with MPa/psi gauge scale, and the reverse-flow valve fitted as an ordering difference. No bracket is included (J), so plan for a panel mount or existing bracket; the gauge is fitted and reads directly. If oil is needed downstream, order the matching GAFC300-08 combination instead. 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 (1/4" 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 GAFR30008SJWK FAQ
Working pressure range is 0.15-0.9 MPa (20-130 psi), with 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. Temperature range is -5 to 70 C and must not freeze. The drain bowl holds 60 cc and the unit weighs 500 g, with a 1/4in port and 5 um filtering grade.
The K indicates a reverse-flow (reflux) valve is fitted to the GAFR30008SJWK. It is an ordering difference shown as a separate pneumatic symbol; the catalogue defers its function to a page not in our data, so confirm the operational detail from the datasheet if needed.
