Airtac GAR Air Regulator GAR30010LK
The AirTAC Airtac GAR Air Regulator GAR30010LK 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 built-in circular pressure gauge. It regulates pressure only — it does not filter the air or remove water.

About the Airtac GAR Air Regulator GAR30010LK
The GAR30010LK is a regulator-only unit that takes a higher supply pressure and holds a steady, lower downstream pressure set by the knob and read on the fitted circular gauge. It does not filter or clean the air, and it has no drain bowl or filter element. This 3/8in model weighs 300 g and regulates the lower band of 0.05-0.4 MPa (7-58 psi).
The pressed-in self-locking knob prevents the set pressure from drifting due to vibration or accidental knocks, so a calibrated low-pressure setting stays put during a shift. The balanced adjustment mechanism also holds the setpoint as supply pressure varies, making this unit a stable choice for precision low-pressure work.

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

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 GAR30010LK Is Used
Low-pressure clamping
Set a gentle, repeatable clamp force on a delicate part in a light assembly fixture. The L type's finer low-band resolution keeps the force consistent without over-stressing the workpiece.
Lab air supply
Feed a sensitive pneumatic instrument or a small test rig that needs a stable 0.2 MPa supply. The balanced design holds the setpoint as the shop air pressure fluctuates during the day.
Paint or coating spray
Regulate the air to a small spray gun at a low, steady pressure. The self-locking knob keeps the fine adjustment from drifting when the gun vibrates during operation.
Is the Airtac GAR Air Regulator GAR30010LK the Right Regulator?
Choose the GAR30010LK when your downstream equipment needs a regulated pressure in the 0.05-0.4 MPa (7-58 psi) band and nothing higher. The L type offers finer resolution over this low range than the standard S type, but it cannot reach a 0.5-0.6 MPa setpoint at all, so it is the wrong part for a standard machine. The 3/8in port suits medium air demand; a GAR200 at 170 g is the smaller step down, while a GAR400 at 570 g is the next size up. The mounting bracket is included, the circular gauge reads MPa/psi, and the thread is PT. A reverse-flow (reflux) valve is attached to this unit. If the line also needs clean air, use the matching GAFR300-10 or a separate GAF filter upstream, because 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 GAR30010LK FAQ
The GAR30010LK is a regulator-only unit with a 3/8in port and a weight of 300 g. It regulates air pressure in the range of 0.05-0.4 MPa (7-58 psi). The maximum supply pressure is 1.0 MPa (145 psi), and the proof pressure is 1.5 MPa (215 psi). The operating temperature range is -20 to 70 C. It has a fitted circular gauge reading MPa/psi, an included mounting bracket, and a PT thread. A reverse-flow (reflux) valve is attached.
The 'L' in the model code means this is a lower-pressure regulator. It regulates in the range of 0.05-0.4 MPa (7-58 psi), offering finer resolution over this low band. The standard 'S' type regulates 0.05-0.9 MPa (7-130 psi). The L type cannot reach a setpoint of 0.5-0.6 MPa at all, so it is specifically for applications that only need low pressure.
