Airtac GAR Air Regulator GAR30015LJK
The AirTAC Airtac GAR Air Regulator GAR30015LJK 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 GAR30015LJK
The GAR30015LJK is a regulator-only unit that takes a higher supply pressure and holds a steady, lower downstream pressure you set with its knob and read on the fitted circular gauge. It does not filter or clean the air, and it has no drain bowl or filter element. This lower-pressure (L) model regulates from 0.05 to 0.4 MPa (7-58 psi), which suits delicate low-pressure circuits rather than standard machinery.
Built on the GAR300 body, this unit has a 1/2" port and weighs 300 g. The pressed-in self-locking knob stops the set pressure drifting from vibration or accidental knocks, so a tuned low-pressure setting stays put during operation. A reverse-flow (reflux) valve is attached to this version. The unit is rated for -20 to 70 C and handles a max supply of 1.0 MPa (145 psi).

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 GAR30015LJK Is Used
Low-pressure pneumatic clamping
Set a gentle, repeatable clamp force on a light assembly fixture where a standard 0.9 MPa regulator would overpower delicate parts. The 1/2" port feeds the clamp cylinder directly, and the self-locking knob holds the low setting through a shift of vibration.
Lab air supply for sensitive instruments
Feed a bench-top pneumatic actuator or a small test rig that needs a stable 0.2 MPa supply. The L type's finer low-band resolution lets you dial in a precise pressure, while the fitted gauge confirms the setpoint at a glance.
Paint or coating fluid-control pilot
Regulate the pilot air for a low-pressure fluid-control valve on a finishing line. The 300 g body mounts on a panel, and the balanced design holds the set pressure as the shop's main supply fluctuates during peak demand.
Is the Airtac GAR Air Regulator GAR30015LJK the Right Regulator?
Choose the GAR30015LJK when your line needs a 1/2" port and a low regulated range of 0.05-0.4 MPa (7-58 psi). The L type gives finer resolution over this low band but cannot reach a 0.5-0.6 MPa setpoint, so it is the wrong part for a standard machine. This version has no mounting bracket (J), so plan for panel mounting or an existing bracket, and it comes with the circular gauge reading MPa/psi on its PT threads. The K code means a reverse-flow (reflux) valve is attached, named here without further detail. If the air also needs cleaning, use the matching GAFR300-15 or a GAF filter upstream, since this regulator does not filter. 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 GAR30015LJK FAQ
The GAR30015LJK is a lower-pressure (L) air pressure regulator with a 1/2" port and a 300 g body. It regulates from 0.05 to 0.4 MPa (7-58 psi). Max 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. It has a fitted circular gauge, no bracket, and a reflux valve attached.
The L type regulates only 0.05-0.4 MPa (7-58 psi) instead of the standard 0.05-0.9 MPa. This gives finer resolution over the low band, which is useful for delicate circuits. However, it cannot reach a 0.5-0.6 MPa setpoint, so it is not suitable for standard machinery that needs higher regulated pressures.
