Airtac GAR Air Regulator GAR30008LJN
The AirTAC GAR Air Regulator GAR30008LJN 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 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 GAR30008LJN
The GAR30008LJN is an air pressure regulator that takes a higher supply and holds a steady lower downstream pressure you set with its knob. It does not filter or clean the air, and it has no drain bowl or filter element. This unit uses a 1/4" port and weighs 300 g, placing it in the mid-size GAR300 class for panel or bracket mounting.
This lower-pressure (L) model regulates from 0.05 to 0.4 MPa (7-58 psi), giving finer resolution across that low band than a standard type. The pressed-in self-locking knob prevents the setpoint from drifting due to vibration or accidental knocks, so a calibrated low-pressure setting stays put during a shift.

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.
Size Class
- GAR2001/8"-1/4" · 170 g
- 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 GAR30008LJN Is Used
Low-pressure clamping
Set a delicate 0.15 MPa clamp force on a light assembly fixture. The L type's finer low-band resolution holds the gentle pressure without overshoot, and the self-locking knob keeps it stable through a production run.
Lab air supply
Feed a sensitive pneumatic instrument that needs a soft 0.2 MPa supply. The 1/4" port suits bench tubing, and the no-gauge design lets you rely on the instrument's own readout for precision.
Paint spray setup
Regulate a low 0.3 MPa to a small spray gun for fine finishing work. The 300 g body mounts neatly on a panel near the work area, and the balanced design holds the setting as the compressor cycles.
Is the Airtac GAR Air Regulator GAR30008LJN the Right Regulator?
Choose the GAR300 body when your line uses 1/4" fittings and needs a compact 300 g regulator. The L type is for low-pressure work only: it cannot reach a 0.5-0.6 MPa setpoint, so pick the standard S type for typical machine pressures. This code has no gauge (N), so read pressure on the line's own panel gauge, and no bracket (J), meaning you mount it directly to a panel or an existing bracket. The PT thread gives a gauge scale in MPa/psi, matching metric crews. If the air also needs cleaning, use a GAFR300-08 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 (1/4" 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 GAR30008LJN FAQ
It is an air pressure regulator with a 1/4" port and a weight of 300 g. The lower-pressure type regulates from 0.05 to 0.4 MPa (7-58 psi). 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. It has no gauge and no bracket.
The L type regulates a lower pressure band of 0.05 to 0.4 MPa (7-58 psi) with finer resolution, while the standard S type covers 0.05 to 0.9 MPa (7-130 psi). The L type cannot reach a 0.5-0.6 MPa setpoint at all, so it is only for low-pressure applications like delicate clamping or spraying.
