Airtac GAR Air Regulator GAR30015LK
The AirTAC GAR Air Regulator GAR30015LK is a genuine compressed-air pressure regulator. It sets and holds a steady downstream pressure across the 0.05 - 0.4 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 GAR30015LK
The GAR30015LK is a lower-pressure air regulator that takes a supply up to 1.0 MPa and holds a steady downstream setting between 0.05 and 0.4 MPa (7-58 psi). Its pressed-in self-locking knob keeps the setpoint stable against vibration and accidental knocks, so a calibrated low-pressure station stays where you left it. This 1/2in unit weighs 300 g and carries a circular gauge with a clip and magnifier for easy reading in tight panels.
This is a regulator only - it does not filter the air or remove water, oil or particles. A reverse-flow (reflux) valve is attached to this model. For clean air, fit a GAF300-15 filter-regulator or a separate GAF filter upstream; the GAR itself only controls pressure.

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 GAR30015LK Is Used
Low-Pressure Pilot Lines
Set a stable 0.2 MPa pilot signal for a sequence of pneumatic valves. The L type's finer low-band resolution keeps the pilot pressure consistent even when the main supply fluctuates.
Precision Blow-Off Stations
Regulate a gentle 0.1 MPa air stream for clearing debris off machined parts. The balanced design holds the low setpoint as the shop compressor cycles, protecting delicate workpieces.
Lab Air Supply
Feed a controlled 0.3 MPa supply to a test fixture or analytical instrument. The self-locking knob prevents drift from bench vibrations, and the 1/2in port handles modest flow demands.
Is the Airtac GAR Air Regulator GAR30015LK the Right Regulator?
Choose the GAR300 body when your line needs a 1/2in port and a 300 g regulator that mounts on a panel or bracket. The L type regulates only 0.05-0.4 MPa, so it suits low-pressure circuits like pilot air or precision blow-off, not standard 0.5-0.6 MPa machine settings. The circular gauge reads MPa/psi on its PT thread, and the included bracket simplifies installation. The K code adds a reflux valve, named here without function detail. If the air also needs cleaning, step up to the GAFR300-15 filter-regulator instead. The S type spans about 2.4x this L type's adjustable band (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 GAR30015LK FAQ
The GAR30015LK is a lower-pressure air regulator with a 1/2in port and a weight of 300 g. It regulates from 0.05 to 0.4 MPa (7-58 psi), handles a maximum supply pressure of 1.0 MPa (145 psi), and has a proof pressure of 1.5 MPa (215 psi). The operating temperature range is -20 to 70 C. It comes with a circular gauge reading MPa/psi and an included mounting bracket.
The K in GAR30015LK indicates a reverse-flow (reflux) valve is attached to the regulator. This is a factory-fitted option on the unit. The GAR itself remains a regulator only - it does not filter or clean the air. For filtration, use a GAFR300-15 or a separate GAF filter upstream.
