The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30015ALJNK 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 - 0.4 MPa (20 - 58 psi). It has no lubricator, so it adds no oil to the airflow.
The GAFR30015ALJNK is a filter and pressure regulator combined into a single body, so incoming air is cleaned and set to a steady outlet pressure without needing separate units. This 1/2in version operates in the lower 0.15-0.4 MPa (20-58 psi) band and uses a 40 um element, with no lubricator fitted anywhere in the design.
Its 60 cc condensate bowl collects water and solids spun out by the diversion structure, while the automatic drain clears it without manual attention. Weighing 500 g, this unit suits panel mounting rather than being supported by tubing, and the absent gauge means the 1/8in connection is ready for a later addition if readouts become necessary.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. No gauge is supplied with this model — the gauge connection on a GAFR300 is 1/8" if you add one. This unit filters and regulates only; it does not add lubrication.

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.

Feed a bench-mounted press or clamping jig that operates below 0.4 MPa, where the lower pressure type prevents accidental over-pressurization of delicate tooling.
Supply a leak-test station or calibration bench with filtered air at a stable low setpoint, using the automatic drain to keep the 60 cc bowl clear during long test runs.
Regulate air for spray equipment in a finishing area, where the 40 um element traps particles and the lower pressure range matches typical atomization requirements.
Choose this GAFR300 body for 1/2in piping where the lower pressure range is sufficient, and step up to a GAFR400 if you need a 7000 L/min flow envelope at 0.7 MPa inlet. The PC bowl suits general duty, while the automatic drain handles wet or unattended lines, and the omitted bracket allows direct panel mounting. The 40 um element is the standard grade, and the PT thread matches common local fittings, with the reflux valve present as an ordering difference only. If oil is needed downstream, order the matching GAFC300-15 combination instead, since this unit does not lubricate. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range.
Quick checklist
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.
It is a filter & regulator with a 1/2in port, working range 0.15-0.4 MPa (20-58 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), temperature range -5 to 70 C, 60 cc drain bowl, and 500 g weight. The element is 40 um, the drain is automatic, and no gauge or bracket is included.
The J code omits the mounting bracket for direct panel installation, and the N code means no gauge is supplied. The 1/8in gauge connection remains available if you add one later, but the set pressure cannot be read without fitting a gauge.
