Airtac GAR Air Regulator GAR20008SJ
The AirTAC Airtac GAR Air Regulator GAR20008SJ is a genuine compressed-air pressure regulator. It sets and holds a steady downstream pressure across the 0.05 - 0.9 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 GAR20008SJ
The GAR20008SJ is a compact 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 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 clean air. This 1/4in unit weighs 170 g, making it the lightest body in the GAR range and a natural fit for small machines or single-tool stations.
The pressed-in self-locking knob keeps the set pressure from drifting when the machine vibrates, so a clamp or tool holds its force through a shift. The balanced adjustment design also holds the setpoint as supply pressure varies, which protects downstream components from swings in the main line. Rated for -20 to 70 C, this standard type regulates from 0.05-0.9 MPa (7-130 psi) and suits most factory air systems.

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 GAFR200 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 GAFR200-08 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 GAR20008SJ Is Used
Single jig or clamp
Set a stable 0.4 MPa on a pneumatic jig that holds a workpiece during drilling. The self-locking knob keeps the pressure from drifting as the drill vibrates the table.
Bench-top air tool
Feed a die grinder or small impact wrench at a regulated 0.6 MPa. The 1/4in port matches common tool inlets, and the gauge lets you verify the setting at a glance.
Lab air supply
Regulate air for a small pneumatic actuator in a test rig. The balanced design holds the setpoint as the building compressor cycles, keeping test conditions repeatable.
Is the Airtac GAR Air Regulator GAR20008SJ the Right Regulator?
Choose the GAR20008SJ when your line uses 1/4in piping and needs a compact regulator for a single tool or small clamp. The 170 g body is light enough for panel mounting, but this J code omits the bracket, so plan for a panel cutout or an existing bracket. The standard S type covers 0.05-0.9 MPa (7-130 psi), which handles typical machine setpoints, while the L type only reaches 0.4 MPa and would be the wrong part for a 0.5 MPa requirement. The circular gauge reads MPa/psi on the PT thread, matching common Asian and European fittings. If the air also needs cleaning, step up to the matching GAFR200-08 filter-regulator or add a GAF filter upstream. The S type's adjustable band spans 0.85 MPa, about 2.4x the L type's 0.35 MPa range, giving you far more setpoint flexibility.
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 GAFR200
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 170 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 GAFR200-08 filter-regulator as your air-prep needs grow.
Airtac GAR Air Regulator GAR20008SJ FAQ
The GAR20008SJ is a standard-type air pressure regulator with a 1/4in port and a 170 g body. It regulates from 0.05-0.9 MPa (7-130 psi), with a maximum supply pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The operating temperature range is -20 to 70 C. It has a fitted circular gauge reading MPa/psi, a PT thread, and no mounting bracket.
The J in the model code means the mounting bracket is omitted. You mount this regulator directly to a panel using the body's mounting holes, or you use an existing bracket from your system. This saves weight and cost when you already have a mounting solution in place.
