Airtac GAR Air Regulator GAR30008LJ
The AirTAC GAR Air Regulator GAR30008LJ 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 GAR30008LJ
The AirTAC GAR30008LJ is a regulator-only unit 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 does not filter or clean the air, has no drain bowl and no filter element, so it must be paired with a GAF or GAFR if the line needs purification.
This 1/4in body weighs 300 g and is the lower-pressure (L) type, regulating from 0.05 to 0.4 MPa (7-58 psi). The pressed-in self-locking knob prevents the setpoint from drifting due to vibration or accidental contact, while the balanced adjustment mechanism keeps the output stable as supply pressure fluctuates.

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 GAR30008LJ Is Used
Low-pressure clamping
Set a gentle, repeatable 0.2 MPa for delicate part-holding fixtures where higher force would deform the workpiece.
Lab air supply
Feed a bench-top pneumatic actuator or test rig at a stable 0.1-0.3 MPa, protecting sensitive downstream equipment from supply swings.
Spray gun regulation
Hold a consistent low pressure for a manual spray gun in a finishing booth, where a steady 0.15-0.25 MPa avoids overspray and uneven coats.
Is the Airtac GAR Air Regulator GAR30008LJ the Right Regulator?
Choose the GAR30008LJ when you need a compact 1/4in regulator for low-pressure work below 0.4 MPa. The L type gives finer resolution over its 0.05-0.4 MPa band, but it cannot reach a 0.5-0.6 MPa setpoint, so for standard machine pressures select the S type instead. This model has no bracket (J), so plan for panel mounting or an existing bracket, and the circular gauge reads MPa/psi on the PT thread. If your air also needs cleaning, step up to the matching GAFR300-08 filter-regulator or add a 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 (1/4" 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 GAR30008LJ FAQ
The GAR30008LJ regulates air from 0.05 to 0.4 MPa (7-58 psi), with a max supply pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It operates from -20 to 70 C and weighs 300 g with a 1/4in PT thread port.
The J in the code means the mounting bracket is omitted, so you need a panel mount or your own bracket. The L type is the lower-pressure version, regulating only 0.05-0.4 MPa (7-58 psi) with finer resolution over that band, unlike the standard S type which reaches 0.9 MPa.
