Airtac GAFR Adjustable Filter Regulator GAFR30015SJK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30015SJK 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 1/2" 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 GAFR30015SJK
The GAFR30015SJK is a filter and regulator combined in a single body, so incoming air is cleaned and then set to a steady outlet pressure without needing separate units. This 1/2in version handles 0.15-0.9 MPa (20-130 psi) and uses a 40 um element to trap particles.
The 60 cc condensate bowl collects the water and solids that the diversion structure spins out of the air stream. This model ships without a mounting bracket, so plan to support the 500 g unit from a panel or frame rather than the tubing.

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 GAFC300-15 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 GAFR30015SJK Is Used
Single station fixture
Feed a single clamping fixture or a small bench press with clean, regulated air at up to 0.9 MPa. The 1/2in port and 500 g mass suit a fixed machine frame.
Test bench supply
Provide a stable pressure source for a pneumatic test rig where the 40 um filter protects sensitive valves and the gauge lets you verify the setpoint.
Short transfer line
Protect a short run of actuators on a packaging or assembly line. The 60 cc bowl handles typical condensate between scheduled drains.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30015SJK the Right Air-Prep Unit?
Choose the GAFR300 body when you need 1/2in ports and a 60 cc drain bowl, which sits between the smaller GAFR200 (25 cc) and the larger GAFR400 (100 cc). The PC bowl is the standard build, and the semi-auto plus manual drain gives you both automatic dumping when pressurized and a manual pull-ring for service. This standard type covers 0.15-0.9 MPa, and the 40 um element is the default for general shop air. The J code means no bracket is included, and the fitted circular gauge reads in MPa/psi on the PT thread. The K code adds the reverse-flow valve, which is an ordering difference only. Since 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, plan a supply near 1.0 MPa if you intend to regulate at the upper end.
Quick checklist
- ✓ Body size for your peak flow (1/2" 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 GAFC300-15 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR30015SJK FAQ
The GAFR30015SJK is a filter & regulator with a 1/2in 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 weight 500 g.
The K code indicates a reverse-flow (reflux) valve is fitted. It is an ordering difference from the standard unit, and its specific function is covered in the catalogue pages not included in this data.
