Airtac GAR Air Regulator GAR30015SNK
The AirTAC GAR Air Regulator GAR30015SNK 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 GAR30015SNK
The GAR30015SNK 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 dry the air, and it has no drain bowl or filter element. This 1/2in model weighs 300 g, placing it in the mid-size GAR300 class for moderate air demands.
Its pressed-in self-locking knob resists vibration and accidental knocks, so the setpoint stays where you left it. The balanced adjustment mechanism also holds the setting as supply pressure fluctuates. With no gauge fitted, you read pressure on the line's own panel gauge instead.

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.
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 GAR30015SNK Is Used
Machine tool pressure setting
Set a steady 0.4 MPa for a pneumatic vise on a drill press, where supply swings would otherwise change clamping force and spoil part location.
Conveyor tension control
Hold a constant 0.3 MPa to a belt tensioner cylinder, keeping the belt taut without over-stretching it as line pressure varies through the shift.
Test rig air supply
Feed a calibrated 0.6 MPa to a leak-test fixture, relying on the balanced design to keep the setpoint stable while other equipment draws from the same header.
Is the Airtac GAR Air Regulator GAR30015SNK the Right Regulator?
Choose the GAR300 body for 1/2in ports and a 300 g mass, a step up from the GAR200 at 170 g for small clamps, and a step down from the GAR400 at 570 g for heavier lines. The standard S type regulates 0.05-0.9 MPa (7-130 psi), covering typical machine pressures; the L type only reaches 0.4 MPa and cannot hit a 0.5-0.6 MPa setpoint. This unit has no gauge (N), so rely on an external panel gauge for readouts, and the PT thread gives MPa/psi scale if you add one. The mounting bracket is included, and the K suffix attaches a reverse-flow (reflux) valve, named here without describing its function. If the air also needs cleaning, use a GAFR filter-regulator 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 (0.85 MPa vs 0.35 MPa), giving finer low-range resolution but less headroom.
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 GAR30015SNK FAQ
The GAR30015SNK regulates air from 0.05 to 0.9 MPa (7-130 psi) with a standard S type. Maximum supply pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and the temperature range is -20 to 70 C. The unit weighs 300 g and has a 1/2in port. It includes a mounting bracket, has no gauge, uses PT threads, and carries a reflux valve.
The N means no pressure gauge is fitted to this regulator. You read the downstream pressure on the line's own panel gauge or install an AirTAC replacement gauge if needed. The K suffix adds a reverse-flow (reflux) valve, which is attached but not described in our data.
