Airtac GAFR Adjustable Filter Regulator GAFR30008ASJWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30008ASJWK 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 GAFR30008ASJWK
The GAFR30008ASJWK is a genuine AirTAC filter & regulator with both functions in a single body, so it takes less rail space than separate GAF and GAR units. It serves a 1/4in port line, regulates from 0.15-0.9 MPa (20-130 psi), and filters with a 5 um element.
The pressed-in self-locking knob resists set-pressure drift from vibration, keeping the outlet steady in industrial environments. This model has a 60 cc condensate bowl, weighs 500 g, and uses an automatic drain to clear collected water and solids.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. The fitted circular gauge reads in MPa / psi, set by the PT thread code. This unit filters and regulates only; it does not add lubrication.

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 GAFR30008ASJWK Is Used
Precision valve control
The 5 um element protects fine pneumatic valves from particle wear, while the balanced regulator holds set pressure for consistent actuation in a small assembly station.
Machine tool air prep
With a 1/4in port and 500 g mass, this unit fits compact machine tool cabinets, supplying clean, regulated air to a single spindle or clamping circuit.
Unattended line filtering
The automatic drain clears condensate without manual checks, making it suitable for a lightly supervised packaging line running on a 1/4in supply.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30008ASJWK the Right Air-Prep Unit?
Choose the GAFR300 body for 1/4in or 3/8in ports; the 3500 L/min flow envelope at 0.7 MPa inlet suits small machine stations. The PC bowl is the standard build, while the automatic drain (A) handles unattended or wet lines, and the 5 um element (W) traps finer particles for sensitive valves. The J code omits the mounting bracket, so plan for panel mounting or an existing bracket, and the K code adds a reverse-flow (reflux) valve as an ordering difference. The fitted circular gauge reads MPa/psi with PT threads; if oil is needed downstream, order the matching GAFC300-08 combination instead. Max supply 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 GAFR30008ASJWK FAQ
It regulates 0.15-0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. Operating temperature is -5 to 70 C, the drain bowl holds 60 cc, and the unit weighs 500 g.
The J code omits the bracket, so you must use a panel mount or an existing bracket. This suits installations where the unit is secured to a machine frame rather than supported by the tubing.
