Airtac GAR Air Regulator GAR30010LNK
The AirTAC Airtac GAR Air Regulator GAR30010LNK is a genuine compressed-air pressure regulator. It sets and holds a steady downstream pressure across the 0.05 - 0.4 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 GAR30010LNK
The GAR30010LNK is an air pressure regulator that takes a higher supply pressure and holds a steady, lower downstream pressure you set with the knob. It does not filter the air, remove water, or separate particles, and it has no drain bowl or filter element. This unit weighs 300 g and uses a 3/8" port, placing it in the mid-size GAR300 class.
This lower-pressure (L) model regulates from 0.05 to 0.4 MPa (7-58 psi), which suits delicate low-pressure circuits. The pressed-in self-locking knob stops the set pressure drifting from vibration, so a calibrated low setting stays put. No pressure gauge is fitted, so the line's own panel gauge shows the downstream reading.

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
- GAR2001/8"-1/4" · 170 g
- GAR3001/4"-1/2" · 300 g

- GAR6003/4"-1" · 1390 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 GAR30010LNK Is Used
Low-pressure clamping
Set a gentle, repeatable clamp force on a delicate workpiece where a standard 0.9 MPa regulator would over-stress the part. The L type's finer low-band resolution holds the 0.1-0.3 MPa range steadily.
Lab air bench
Feed a laboratory pneumatic circuit that needs a soft, stable 0.2 MPa supply for sensitive instruments. The self-locking knob keeps the low setpoint from drifting during a long experiment.
Precision spray control
Regulate air to a fine spray nozzle or an airbrush station where supply swings would ruin the finish. The balanced valve design holds the set pressure as the upstream supply varies.
Is the Airtac GAR Air Regulator GAR30010LNK the Right Regulator?
Choose the body and port first: GAR300 sits between the smaller GAR200 (170 g, 1/8"-1/4") and the larger GAR400 (570 g, 3/8"-1/2"). This 3/8" port feeds moderate air demand, while the 300 g mass needs a proper panel or bracket mount rather than support from the tubing. The L type regulates only 0.05-0.4 MPa (7-58 psi), so it cannot reach a 0.5-0.6 MPa setpoint; pick the S type if you need standard shop pressure. The N code means no gauge is fitted, and the included bracket suits panel mounting. Thread is PT with a gauge scale of MPa/psi. The K code attaches a reverse-flow (reflux) valve, named here without describing its function. If the line also needs clean air, use the matching GAFR300-10 or a GAF filter upstream, since this regulator does not clean the air. 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 (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 GAR30010LNK FAQ
The GAR30010LNK is an air pressure regulator with a 3/8" port and a weight of 300 g. It regulates 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). The temperature range is -20 to 70 C. It has no gauge fitted and includes a mounting bracket.
The L type regulates only 0.05-0.4 MPa (7-58 psi), giving finer resolution over that low band compared to the standard S type. It cannot reach a 0.5-0.6 MPa setpoint, so it is the wrong part for a standard machine. The K code indicates a reverse-flow (reflux) valve is attached; our data names this option but does not describe its function.
