Airtac GAR Air Regulator GAR30010LJN
The AirTAC Airtac GAR Air Regulator GAR30010LJN 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 GAR30010LJN
The GAR30010LJN is an air pressure regulator that takes a higher supply and holds a steady lower downstream pressure, set by its knob. It regulates pressure only - it does not filter, clean, or dry the air, and has no drain bowl or filter element. This unit has a 3/8" port and weighs 300 g, placing it in the mid-size GAR300 class for typical machine circuits.
This lower-pressure (L) type regulates from 0.05-0.4 MPa (7-58 psi), giving finer resolution over that low band for delicate applications. The pressed-in self-locking knob prevents the setpoint from drifting due to vibration or accidental contact. With no gauge fitted, pressure is read on the line's own panel gauge instead.

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.

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 GAR30010LJN Is Used
Low-pressure pneumatic clamping
Set a gentle, repeatable clamp force on delicate parts or thin-walled components where a standard 0.9 MPa regulator would risk damage. The L type's finer low-band resolution helps hold a precise 0.2 MPa setting.
Laboratory air supply
Regulate a bench or instrument air line down to a stable low pressure for sensitive lab equipment. The self-locking knob keeps the setpoint steady against bench vibrations and accidental knocks.
Paint spray or blow-off station
Feed a consistent low-pressure air supply to a spray gun or blow-off nozzle. The balanced design holds the set pressure as the shop supply fluctuates, so the finish stays even.
Is the Airtac GAR Air Regulator GAR30010LJN the Right Regulator?
Choose the GAR30010LJN when your circuit needs a regulated low pressure between 0.05-0.4 MPa (7-58 psi) and a 3/8" port connection. The L type offers finer adjustment over this low band compared to the standard S type, but it cannot reach a 0.5-0.6 MPa setpoint at all - so for standard machine pressures, select the S type instead. This model has no gauge (N), so you must rely on a line or panel gauge to read the set pressure. It also omits the mounting bracket (J), meaning you will need a panel mount or an existing bracket. The PT thread reads MPa/psi on any gauge you fit. If the air also needs cleaning, use the matching GAFR300-10 filter-regulator or a separate GAF filter upstream. The standard S type's 0.05-0.9 MPa band is about 2.4x this L type's adjustable span.
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 GAR30010LJN FAQ
The GAR30010LJN is a lower-pressure (L) air regulator with a 3/8" port and a weight of 300 g. It regulates from 0.05-0.4 MPa (7-58 psi). Maximum supply pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). The operating temperature range is -20 to 70 C. This model has no gauge and no mounting bracket.
The 'N' in the code GAR30010LJN means no pressure gauge is fitted to the regulator. This is for installations that already have a panel or line gauge to display the downstream pressure. You would read the set pressure from that separate gauge instead of one on the regulator body.
