Airtac GAR Air Regulator GAR30015SGK
The AirTAC Airtac GAR Air Regulator GAR30015SGK 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 GAR30015SGK
The AirTAC GAR30015SGK is a regulator-only unit that takes a higher supply pressure and holds a steady downstream pressure you set with the knob and read on the circular gauge. It does not filter the air, remove water, or separate particles - a separate GAF or GAFR handles cleaning.
This 1/2in model weighs 300 g and uses the standard S type, regulating from 0.05-0.9 MPa (7-130 psi). The pressed-in self-locking knob keeps the setpoint from drifting when the machine vibrates, so a calibrated pressure stays put until you change it.

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 GAR30015SGK Is Used
CNC fixture clamping
Set a stable 0.4 MPa for pneumatic clamps on a machining center. The self-locking knob holds the pressure through spindle vibration, keeping parts seated consistently.
Assembly station air supply
Feed a steady 0.3 MPa to screwdrivers and presses on a manual assembly line. The 1/2in port delivers enough air for several tools without pressure sag.
Test bench pressure source
Use it to set a precise 0.6 MPa for testing valve actuators or cylinders. The balanced design holds the setpoint as the shop compressor cycles.
Is the Airtac GAR Air Regulator GAR30015SGK the Right Regulator?
Choose the GAR30015SGK when your line needs a 1/2in port and a standard 0.05-0.9 MPa regulated range. The body sits between the lighter GAR200 at 170 g and the heavier GAR400 at 570 g, so it fits mid-size equipment where a small unit is undersized and a large one is overkill. The G thread gives a bar/MPa gauge scale, the bracket is included for panel mounting, and the K code adds a reverse-flow (reflux) valve. If the air also needs cleaning, step up to the matching GAFR300-15 filter-regulator instead. The S type's adjustable band is about 2.4x the L type's span (0.85 MPa vs 0.35 MPa), giving you a wider range of setpoints.
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 GAR30015SGK FAQ
The GAR30015SGK regulates air from 0.05-0.9 MPa (7-130 psi) with a maximum supply of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It operates from -20 to 70 C and weighs 300 g. The port is 1/2in and the gauge reads in bar/MPa.
The K indicates a reverse-flow (reflux) valve is attached to the regulator outlet. This model includes it as a fitted option. The valve's function is not detailed in our data - it is simply named as part of the configuration.
