Airtac GAR Air Regulator GAR30008LJK
The AirTAC Airtac GAR Air Regulator GAR30008LJK is a genuine compressed-air pressure regulator. It sets and holds a steady downstream pressure across the 0.05 - 0.4 MPa range, with 1/4" 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 GAR30008LJK
The GAR30008LJK is an air pressure regulator that takes a higher supply pressure and holds a steady, lower downstream pressure you set with the knob and read on the fitted circular gauge. It is a regulator only - it does not filter the air, remove water, or separate particles, and it has no drain bowl or filter element.
This lower-pressure (L) model regulates from 0.05-0.4 MPa (7-58 psi), ideal for fine low-pressure control. With a 1/4in port and 300 g mass, it suits compact pneumatic circuits. The pressed-in self-locking knob prevents the setpoint from drifting due to vibration or accidental knocks, while the balanced adjustment mechanism holds the 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 GAFR300-08 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 GAR30008LJK Is Used
Low-pressure clamping
Set a gentle, repeatable clamp force on delicate workpieces in assembly fixtures, where the 0.05-0.4 MPa range prevents crushing and the self-locking knob holds the setting through production vibration.
Lab air supply
Regulate air for laboratory pneumatic controls or test rigs that need a stable low pressure, with the circular gauge giving a clear readout and the 1/4in port suiting small-bore tubing.
Precision spray or blow-off
Feed a controlled low-pressure air supply to a spray gun or blow-off nozzle, where the balanced design keeps the outlet steady even if the shop supply fluctuates.
Is the Airtac GAR Air Regulator GAR30008LJK the Right Regulator?
Choose the GAR30008LJK when you need precise regulation in the low band of 0.05-0.4 MPa (7-58 psi) - the L type gives finer resolution here but cannot reach a 0.5-0.6 MPa setpoint, so it is wrong for standard machines. This unit has no mounting bracket (J option), so plan for panel mounting or an existing bracket; the circular gauge is fitted and reads MPa/psi on the PT thread. The K code means a reverse-flow (reflux) valve is attached. If your line also needs clean air, use a GAFR300-08 or a separate GAF filter upstream - this regulator does not clean the air. 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 (1/4" 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 GAFR300-08 filter-regulator as your air-prep needs grow.
Airtac GAR Air Regulator GAR30008LJK FAQ
The GAR30008LJK is a lower-pressure air regulator with a 1/4in port and 300 g weight. It regulates from 0.05-0.4 MPa (7-58 psi), with a max supply pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Operating temperature is -20 to 70 C. It has a fitted circular gauge reading MPa/psi, a PT thread, no mounting bracket, and a reflux valve attached.
The L type means lower-pressure regulation from 0.05-0.4 MPa (7-58 psi), giving finer control in that low band compared to the standard S type. The K code indicates a reverse-flow (reflux) valve is attached to this unit. This regulator does not filter air - for clean air, use a GAFR or GAF upstream.
