Airtac GAR Air Regulator GAR40010LNK
The AirTAC Airtac GAR Air Regulator GAR40010LNK 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 GAR40010LNK
The GAR40010LNK is an air pressure regulator that takes a higher supply pressure and holds a steady, lower downstream pressure set by the operator. It is a regulator only - it does not filter, clean, or dry the air, and has no drain bowl or filter element. This 3/8in unit weighs 570 g and regulates in the lower 0.05-0.4 MPa (7-58 psi) band, making it ideal for low-pressure applications that need fine adjustment.
The pressed-in self-locking knob prevents the set pressure from drifting due to vibration or accidental knocks, so a tuned setting stays put during production runs. The balanced adjustment mechanism holds the setpoint as supply pressure varies. This model has no gauge fitted, so pressure is read on the line's own panel gauge, and a reverse-flow (reflux) valve is attached. The mounting bracket is included for panel or wall installation.

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 GAFR400 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 GAFR400-10 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 GAR40010LNK Is Used
Low-pressure clamping circuits
Set a delicate 0.2 MPa clamp force on a fixture holding thin-walled parts. The L type's fine low-band adjustment prevents crushing while the self-locking knob holds the setting through a shift of vibration.
Lab pneumatic controls
Regulate air to a test rig or analytical instrument that needs a stable 0.1-0.3 MPa supply. The balanced design keeps the setpoint steady as the shop compressor cycles, protecting sensitive downstream equipment.
Paint or spray systems
Feed a low-pressure atomizing air supply to a spray gun at 0.3 MPa. The 3/8in port handles the demand, and the included bracket mounts the regulator near the work station for quick operator adjustments.
Is the Airtac GAR Air Regulator GAR40010LNK the Right Regulator?
Choose the GAR400 body for 3/8in porting with a 570 g mass, a step up from the GAR300 at 300 g for higher air demand. The L type regulates only 0.05-0.4 MPa (7-58 psi) with finer resolution over that low band, but it cannot reach a 0.5-0.6 MPa setpoint - select the S type if standard machine pressures are needed. The N code means no gauge is fitted, so rely on a panel gauge in the line; the included bracket mounts the regulator securely. PT threads read MPa/psi on the gauge scale, and the K code adds a reverse-flow (reflux) valve. If the air also needs cleaning, use a GAFR filter-regulator or a GAF filter upstream. The S type's 0.05-0.9 MPa band (0.85 MPa wide) is about 2.4x this L type's 0.05-0.4 MPa band (0.35 MPa wide).
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 GAFR400
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 570 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 GAFR400-10 filter-regulator as your air-prep needs grow.
Airtac GAR Air Regulator GAR40010LNK FAQ
The GAR40010LNK is a lower-pressure (L type) air regulator with a 3/8in port and a 570 g weight. It regulates from 0.05-0.4 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). Operating temperature is -20 to 70 C. It has no gauge fitted, includes a mounting bracket, uses PT threads, and has a reverse-flow (reflux) valve attached.
The N in GAR40010LNK means no pressure gauge is fitted to the regulator. You would read the downstream pressure on a separate panel gauge installed in the line. This is useful when the regulator is mounted in a location where a local gauge is not needed or would be redundant.
