The AirTAC Airtac GAR Air Regulator GAR30008SJNK is a genuine compressed-air pressure regulator. It sets and holds a steady downstream pressure across the 0.05 - 0.9 MPa range, with 1/4" ports and a no-gauge (N) port for a panel gauge. It regulates pressure only — it does not filter the air or remove water.
The GAR30008SJNK is an air pressure regulator that takes a higher, varying supply and holds a steady, lower downstream pressure you set with its knob. It is a regulator only - it does not filter the air, remove water, or clean particles, and it has no drain bowl or filter element.
This 1/4in unit weighs 300 g and uses the standard type, regulating from 0.05-0.9 MPa (7-130 psi). It ships without a gauge and without a mounting bracket, and it carries a reverse-flow (reflux) valve. The pressed-in self-locking knob stops the set pressure from drifting due to vibration or accidental knocks.

Specifications follow the official AirTAC GAR catalogue (pages 228-229). This is a regulator only — it sets and holds a downstream pressure but does not filter the air or separate water. To clean the air as well, use the matching GAFR300 filter-regulator or add a GAF filter upstream. Never run above the 1.5 MPa (215 psi) proof pressure.

A GAR regulates pressure but does not filter — there is no bowl, element or drain code. Need to clean the air too? The matching GAFR300-08 is the same regulator with a built-in filter.
All bodies share the same 0.05-0.9 MPa (S) regulated range, 1.0 MPa max and 1.5 MPa proof; the body number sets the port size and the flow the regulator can pass. Bigger ports feed higher air demand. The catalogue plots a flow curve at 0.7 MPa inlet but prints no numeric envelope, so size by port and weight and confirm the curve for a real duty point.

Set a steady 0.3 MPa for a small pneumatic clamp on an assembly fixture. The self-locking knob keeps the pressure stable through a full shift of vibrations.
Feed one air tool like a screwdriver or a small grinder at a fixed pressure. The 1/4in port matches common tool inlets, and the 300 g body mounts easily on a panel.
Hold a precise low pressure for a bench test setup. The standard range covers 0.05-0.9 MPa, and the no-gauge design lets you use the rig's own digital sensor.
Choose the GAR300 body when you need a 1/4in port and a 300 g unit for light to medium duty lines. The standard S type gives a wide 0.05-0.9 MPa (7-130 psi) band, while the L type only reaches 0.4 MPa and is for low-pressure work only. This model has no gauge, so read pressure on the line's own panel gauge, and it omits the bracket for panel mounting or an existing mount. The PT thread reads MPa/psi on the gauge scale, and the K option attaches a reverse-flow valve. If the line also needs clean air, use a GAFR300-08 or a separate GAF filter upstream, since this regulator does not filter. The S type's adjustable band is about 2.4x the L type's span (0.85 MPa vs 0.35 MPa).
Quick checklist
This is a regulator only — it sets and holds pressure but does not filter or lubricate. Add a GAF filter, a GAL lubricator, or step up to the GAFR300-08 filter-regulator as your air-prep needs grow.
The GAR30008SJNK is a standard-type air pressure regulator with a 1/4in port and a 300 g body. It regulates from 0.05-0.9 MPa (7-130 psi), with a max supply pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The temperature range is -20 to 70 C. It has no gauge, no bracket, and includes a reflux valve.
The K indicates a reverse-flow (reflux) valve is attached to the regulator. This is a factory-fitted option. Our data does not describe its function or benefits, so we recommend checking the AirTAC datasheet for operational details if you need them.
