Airtac GAR Air Regulator GAR30008SJK
The AirTAC GAR Air Regulator GAR30008SJK 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 GAR30008SJK
The AirTAC GAR30008SJK is a regulator-only unit that takes a higher supply pressure and holds a steady lower setpoint you dial in on the knob and read on the circular gauge. It does not filter the air or remove water; for clean air you need a GAFR or a GAF filter upstream.
This standard-type model regulates 0.05-0.9 MPa (7-130 psi) through its 1/4in port, weighs 300 g, and includes a pressed-in self-locking knob that resists drift from vibration. The balanced adjustment mechanism keeps the set pressure stable as supply pressure varies, and the unit is rated for -20 to 70 C.

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

- 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 GAR30008SJK Is Used
Precision clamping
Set a steady 0.4 MPa for a pneumatic clamp on a small assembly fixture, keeping force consistent despite supply swings from other equipment.
Single tool supply
Regulate pressure to one air tool like a screwdriver or grinder, protecting it from overpressure and maintaining torque output.
Lab air bench
Hold a precise low pressure for a test rig or air bearing, with the gauge giving a clear readout for fine adjustment.
Is the Airtac GAR Air Regulator GAR30008SJK the Right Regulator?
Choose the GAR300 body when you need a mid-size regulator for a 1/4in line; it weighs 300 g versus 170 g for the smaller GAR200, so it suits slightly higher air demand. This model is type S, giving the full 0.05-0.9 MPa band, and comes without a bracket (J) for panel mounting or an existing bracket. The circular gauge is fitted with an MPa/psi scale for PT threads, and a reverse-flow (reflux) valve is attached (K). If your line also needs filtration, step up to the matching GAFR300-08. The S type's 0.05-0.9 MPa band is about 2.4x the span of the L type's 0.05-0.4 MPa range.
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 GAR30008SJK FAQ
The GAR30008SJK is a standard-type regulator with a 0.05-0.9 MPa (7-130 psi) regulated range. Max supply pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), temperature range is -20 to 70 C, and it weighs 300 g. It has a 1/4in PT port and a fitted circular gauge.
The K indicates a reverse-flow (reflux) valve is attached to the GAR30008SJK. It is named in the code but its function is not detailed in our data. The unit remains a regulator only and does not filter or clean the air.
