Airtac GAFR Adjustable Filter Regulator GAFR30015SJW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30015SJW 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 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 GAFR30015SJW
This AirTAC GAFR30015SJW is a filter and regulator combined into a single body, eliminating the need for separate GAF and GAR units. It handles a 1/2in port with a 5 um element, working across 0.15-0.9 MPa (20-130 psi) while the 60 cc condensate bowl captures separated water and solids.
The diversion structure spins incoming air to drop liquid and particles into the bowl before the balanced regulator stabilizes outlet pressure. At 500 g, this unit suits panel or frame mounting rather than tubing support, and the included circular gauge with MPa/psi scale lets operators verify set pressure at a glance.

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 GAFR30015SJW Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a small assembly station, where the 5 um element protects fine internal passages from particulates.
Machine tool air supply
Supply regulated air to a single-axis positioning table or small clamping fixture, with the 60 cc bowl handling typical condensate between shifts.
Light production line
Support a modest production line section with consistent 0.15-0.9 MPa output, using the semi-auto drain for manual or automatic condensate release.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30015SJW the Right Air-Prep Unit?
Choose the GAFR300 body for 1/2in port applications needing up to 3500 L/min flow envelope at 0.7 MPa inlet, stepping down from the GAFR400's 7000 L/min envelope for lighter duty. The PC bowl suits general shop air, while the 5 um element traps finer particles than the standard 40 um grade, ideal for precision valves. This model ships with both semi-auto and manual drains, and the J code means no mounting bracket is included. The standard pressure type covers 0.15-0.9 MPa, and the PT thread pairs with the MPa/psi gauge scale. If oil is needed downstream, order the matching GAFC300-15 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 (1/2" 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 GAFR30015SJW FAQ
This filter & regulator has a 1/2in port, 0.15-0.9 MPa (20-130 psi) working range, 1.0 MPa (145 psi) max pressure, 1.5 MPa (215 psi) proof pressure, -5 to 70 C temperature range, 60 cc drain bowl, and weighs 500 g. It uses a 5 um element and has both semi-auto and manual drains.
The J code in GAFR30015SJW means the mounting bracket is omitted. This suits installations using an existing panel mount or custom frame, rather than the standard bracket that comes with blank codes. The unit still requires proper support due to its 500 g weight.
