Airtac GAR Air Regulator GAR30015LJN
The AirTAC Airtac GAR Air Regulator GAR30015LJN 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 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 GAR30015LJN
The GAR30015LJN is an air pressure regulator that takes a higher supply pressure and holds a steady lower downstream pressure you set with the knob. It does not filter or clean the air; it only regulates pressure. This unit has a 1/2in port, weighs 300 g, and is the lower-pressure type with a regulated range of 0.05-0.4 MPa (7-58 psi).
The pressed-in self-locking knob prevents the set pressure from drifting due to vibration or accidental knocks, keeping your downstream equipment stable. With no gauge fitted, you read the pressure on the line's own panel gauge. The balanced adjustment mechanism helps the regulator hold its setting as supply pressure varies.

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

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 GAR30015LJN Is Used
Low-pressure pneumatic clamping
Set a gentle, repeatable clamp force on delicate parts in assembly fixtures. The 0.05-0.4 MPa range gives fine control for light-duty holding without damaging components.
Lab air supply regulation
Feed a steady low-pressure air supply to laboratory instruments or test rigs. The lower range and self-locking knob keep the setpoint stable during experiments.
Precision painting or coating
Regulate air for spray application where consistent low pressure matters. The balanced design holds the setting as the supply fluctuates, supporting even coating results.
Is the Airtac GAR Air Regulator GAR30015LJN the Right Regulator?
Choose the GAR30015LJN when you need a 1/2in port regulator for lower-pressure applications. The L type regulates only 0.05-0.4 MPa (7-58 psi), which is ideal for fine control in low-pressure circuits but cannot reach a 0.5-0.6 MPa setpoint. This model has no bracket (J), so plan for panel mounting or use an existing bracket; it also has no gauge (N), so rely on a line gauge. The PT thread reads MPa/psi on the gauge scale. If the air also needs cleaning, use a GAFR300-15 or a separate GAF filter upstream. The standard 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 GAR30015LJN FAQ
The GAR30015LJN is a lower-pressure regulator with a regulated range of 0.05-0.4 MPa (7-58 psi). Maximum supply pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and temperature range is -20 to 70 C. It has a 1/2in port and weighs 300 g.
The N means no pressure gauge is fitted. You read the downstream pressure on the line's own panel gauge instead. This model also has no bracket (J), so it is designed for panel mounting or use with an existing bracket.
