Airtac GAR Air Regulator GAR30015SJK
The AirTAC Airtac GAR Air Regulator GAR30015SJK is a genuine compressed-air pressure regulator. It sets and holds a steady downstream pressure across the 0.05 - 0.9 MPa range, with 1/2" ports and a built-in circular pressure gauge. It regulates pressure only — it does not filter the air or remove water.

About the Airtac GAR Air Regulator GAR30015SJK
The GAR30015SJK is an air pressure regulator that takes a higher supply pressure and holds a steady, lower downstream pressure you set with the knob and read on the circular gauge. It does not filter or clean the air, and it has no drain bowl or filter element.
This standard-type unit regulates from 0.05-0.9 MPa (7-130 psi), weighs 300 g, and has a 1/2in port. The pressed-in self-locking knob prevents the set pressure from drifting due to vibration or accidental knocks, while the balanced adjustment mechanism holds the setting as supply pressure varies.

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 GAFR300-15 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.

Where the Airtac GAR Air Regulator GAR30015SJK Is Used
Precision clamping fixtures
Set a stable 0.3 MPa for pneumatic clamps on a machining fixture, keeping hold force consistent despite supply swings from other equipment.
Single-station assembly bench
Regulate air for one pneumatic screwdriver or press at a dedicated assembly station, with the gauge letting operators verify the setpoint.
Lab test rig air supply
Feed a controlled 0.2 MPa to a test fixture or air bearing, isolating the experiment from plant pressure fluctuations.
Is the Airtac GAR Air Regulator GAR30015SJK the Right Regulator?
Choose the GAR30015SJK when you need a 1/2in port with a standard 0.05-0.9 MPa (7-130 psi) range. The J suffix means no mounting bracket is included, so plan for panel mounting or an existing bracket. The K suffix indicates a reverse-flow (reflux) valve is attached, and the PT thread uses an MPa/psi gauge scale. If your line also needs clean air, use a GAFR300-15 or a separate GAF filter upstream, since this regulator does not filter. The standard type's adjustable band is about 2.4x the lower-pressure type's span (0.85 MPa vs 0.35 MPa).
Quick checklist
- ✓ Body size for your air demand (1/2" here)
- ✓ Type S (0.05-0.9) or L (0.05-0.4 MPa)
- ✓ Gauge fitted, or no gauge (N)
- ✓ Thread PT / G / NPT (sets gauge scale)
- ✓ Bracket kept or removed (J)
- ✓ Need filtration too? Use GAFR300
Installation & Setting Notes
- check Install with the airflow arrow: IN to OUT, knob accessible.
- check Put a filter (GAF or a GAFR) UPSTREAM — a regulator does not clean the air.
- check Set pressure by turning the knob up to the target, then press it in to lock.
- check Keep supply at or below the 1.0 MPa (145 psi) max working pressure.
- check Never exceed the 1.5 MPa (215 psi) proof pressure.
- check Support the 300 g unit on its panel or bracket, not on the tubing.
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 GAFR300-15 filter-regulator as your air-prep needs grow.
Airtac GAR Air Regulator GAR30015SJK FAQ
The GAR30015SJK is a standard-type air pressure regulator with a 1/2in port and a regulated range of 0.05-0.9 MPa (7-130 psi). Maximum supply pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and operating temperature is -20 to 70 C. The unit weighs 300 g and has a circular gauge fitted.
The K suffix means a reverse-flow (reflux) valve is attached to the GAR30015SJK. This valve is part of the assembly, but our data does not describe its function or benefits. The regulator itself only controls pressure and does not filter or clean the air.
