Airtac GAR Air Regulator GAR30010SJNK
The AirTAC Airtac GAR Air Regulator GAR30010SJNK is a genuine compressed-air pressure regulator. It sets and holds a steady downstream pressure across the 0.05 - 0.9 MPa range, with 3/8" 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 GAR30010SJNK
The GAR30010SJNK is a regulator-only air pressure control unit from AirTAC. It takes a higher supply pressure and holds a steady, lower downstream pressure that you set with the knob. It does not filter, clean, or dry the air, and it has no drain bowl or filter element. This model uses a 3/8in port and weighs 300 g, placing it in the mid-size GAR300 class.
This standard-type unit regulates from 0.05-0.9 MPa (7-130 psi). The pressed-in self-locking knob prevents the set pressure from drifting due to vibration or accidental contact. A balanced adjustment mechanism helps the regulator hold its setting as the supply pressure varies. This version comes without a gauge and without a mounting bracket, and it includes a reverse-flow (reflux) valve.

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 GAFR300-10 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 GAR30010SJNK Is Used
Machine tool pressure set
Set a stable 0.4 MPa for a pneumatic clamp on a CNC machine. The self-locking knob holds the setting through the machine's vibration, keeping the clamp force consistent.
Test bench air supply
Provide a regulated 0.6 MPa to a manual test fixture on an engineering bench. The 3/8in port feeds the fixture's small cylinders and the balanced design resists supply swings.
Assembly line tool feed
Regulate air for a pneumatic screwdriver on an assembly line. The 300 g body mounts neatly on the workbench, and the reflux valve is fitted for this specific line setup.
Is the Airtac GAR Air Regulator GAR30010SJNK the Right Regulator?
Choose the GAR30010SJNK when you need a 3/8in port regulator for a mid-size air line. The GAR300 body weighs 300 g, which is lighter than the GAR400 at 570 g, so it suits applications where a compact unit is preferred. This is the standard S type, giving you a wide 0.05-0.9 MPa (7-130 psi) adjustment band, unlike the L type which only reaches 0.4 MPa. The N code means no gauge is fitted, so you would read pressure on the line's own panel gauge. The J code omits the mounting bracket, so plan for panel mounting or an existing bracket. The thread is PT, and the gauge scale would read MPa/psi if one were fitted. The K code indicates a reverse-flow (reflux) valve is attached. If your line also needs clean air, use a GAFR filter-regulator or a GAF filter upstream, as this unit does not filter. The S type's adjustable band is about 2.4x the L type's span (0.85 MPa vs 0.35 MPa).
Quick checklist
- ✓ Body size for your air demand (3/8" 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 GAFR300-10 filter-regulator as your air-prep needs grow.
Airtac GAR Air Regulator GAR30010SJNK FAQ
The GAR30010SJNK is a standard-type air pressure regulator with a 3/8in port. It regulates from 0.05-0.9 MPa (7-130 psi). The maximum supply pressure is 1.0 MPa (145 psi), and the proof pressure is 1.5 MPa (215 psi). It operates in temperatures from -20 to 70 C and weighs 300 g. It has no gauge and no bracket, and it includes a reflux valve.
The N in GAR30010SJNK means no pressure gauge is fitted. You would read the downstream pressure on the line's own panel gauge or install a separate gauge. This model also has a J code for no bracket and a K code for a reverse-flow (reflux) valve attached.
