Airtac GAR Air Regulator GAR30015SK
The AirTAC Airtac GAR Air Regulator GAR30015SK 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 GAR30015SK
The GAR30015SK is a regulator-only unit that takes a variable supply and holds a steady downstream pressure you set with its knob. It does not filter or clean the air, and it has no drain bowl or filter element. This model has a 1/2in port, weighs 300 g, and uses the standard 0.05-0.9 MPa (7-130 psi) range.
A pressed-in self-locking mechanism keeps the setpoint from drifting when the machine vibrates or the knob gets knocked. The circular gauge with its clip and magnifier reads MPa/psi and saves panel space. A reverse-flow (reflux) valve is attached to this unit.

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 GAR30015SK Is Used
Machine tool pressure set
Set a steady 0.4 MPa for a drill feed cylinder on a small machining station. The self-locking knob holds the setting through cycle vibrations.
Single-station pneumatic press
Regulate the force of a bench press by setting the air pressure to the cylinder. The 1/2in port feeds the valve bank without restricting demand.
Lab test fixture air supply
Hold a precise pressure for a leak-test fixture. The balanced design keeps the outlet stable as the shop compressor cycles.
Is the Airtac GAR Air Regulator GAR30015SK the Right Regulator?
Choose the body by port size and weight: the GAR300 at 300 g suits 1/4in to 1/2in lines, while the smaller GAR200 at 170 g handles 1/8in to 1/4in ports. This standard S type covers 0.05-0.9 MPa, so it reaches typical machine pressures; the L type only goes to 0.4 MPa and would be wrong for a 0.6 MPa setpoint. The gauge is fitted here and reads MPa/psi on the PT thread, which matches most local installations. The mounting bracket is included, and the K code means a reflux valve is attached. If the line also needs clean air, use a GAFR300-15 or a GAF filter upstream, since this regulator does not filter. 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 GAR30015SK FAQ
The GAR30015SK regulates air from 0.05 to 0.9 MPa (7-130 psi). Maximum supply pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). It operates from -20 to 70 C and weighs 300 g. The port is 1/2in and the body is GAR300.
The K indicates a reverse-flow (reflux) valve is attached to the regulator. This is a factory-fitted option on the GAR30015SK. The valve is included with the unit and does not require separate installation.
