Airtac GAR Air Regulator GAR30015SN
The AirTAC Airtac GAR Air Regulator GAR30015SN 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 no-gauge (N) port for a panel gauge. It regulates pressure only — it does not filter the air or remove water.

About the Airtac GAR Air Regulator GAR30015SN
The AirTAC GAR30015SN is a regulator-only unit that takes a higher supply pressure and holds a steady, lower downstream pressure you set with its knob. It does not filter the air or remove water, so install a separate GAF or GAFR upstream if the line needs cleaning. This 1/2in model weighs 300 g and regulates in the standard 0.05-0.9 MPa (7-130 psi) band.
Its pressed-in self-locking knob prevents the setpoint from drifting when the machine vibrates, so a calibrated pressure stays put during a shift. The balanced adjustment mechanism also holds the setting as supply pressure varies. With no gauge fitted, read the downstream pressure on the line's own panel gauge.

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.
Model Code: Airtac GAR Air Regulator GAR30015SN
| GAR300 | GA300 series air regulator — sets the port range and weight class. |
|---|---|
| 15 | Port size 1/2". This body offers 08 = 1/4", 10 = 3/8", 15 = 1/2". |
| S | Standard regulation: 0.05 - 0.9 MPa (7 - 130 psi). This body offers S (standard) or L (lower 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.
Size Class

- GAR3001/4"-1/2" · 300 g

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 GAR30015SN Is Used
Machine tool pressure set
Set a steady 0.4 MPa for a drill feed cylinder on a small machining station, keeping the thrust consistent as shop supply pressure fluctuates.
Assembly line air header
Feed a 1/2in manifold that supplies several pneumatic screwdrivers, holding a stable 0.6 MPa so each tool gets the same torque.
Test rig supply control
Regulate air to a leak-test fixture at 0.3 MPa, relying on the self-locking knob to hold the test pressure through repeated cycles.
Is the Airtac GAR Air Regulator GAR30015SN the Right Regulator?
Choose the GAR300 body for 1/2in ports and a 300 g mass, stepping up from the lighter 170 g GAR200 when the line needs more air. The S type covers 0.05-0.9 MPa (7-130 psi), which suits standard machines; pick the L type only for low-pressure work below 0.4 MPa. This model ships with the mounting bracket included and uses PT threads, whose gauge scale reads MPa/psi. For clean air, pair it with a GAFR300-15 or a GAF filter upstream. The S type's adjustable band is about 2.4x the L type's span.
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 GAR30015SN FAQ
The GAR30015SN is a standard-type regulator with a 1/2in port and a 300 g weight. 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). It operates from -20 to 70 C and has no pressure gauge fitted.
The 'N' in the model code means no gauge is fitted, reducing cost and panel space. You read the downstream pressure on the line's own panel gauge or install an AirTAC replacement gauge if needed. The PT thread option means the gauge scale would read MPa/psi.
