Airtac GAR Air Regulator GAR40010L
The AirTAC Airtac GAR Air Regulator GAR40010L 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 GAR40010L
The GAR40010L is an air pressure regulator that takes a higher supply pressure and holds a steady, lower downstream pressure you set with the knob and read on the circular gauge. It regulates pressure only; it does not filter, clean, dry, or remove water or particles from the air, and it has no drain bowl or filter element.
This 3/8in model weighs 570 g and is the lower-pressure L type, regulating from 0.05 to 0.4 MPa (7-58 psi). Its pressed-in self-locking knob stops the set pressure drifting from vibration or accidental knocks, so a tuned setting stays put on a production line.

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

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 GAR40010L Is Used
Low-pressure clamping
Set a precise 0.2 MPa for a delicate workpiece clamp on a light assembly fixture, where the finer L-type resolution prevents over-clamping and part damage.
Lab air supply
Feed a stable 0.15 MPa to a laboratory pneumatic actuator or test rig, holding the low setpoint against supply swings from other equipment on the same line.
Painting or coating
Regulate atomising air to a spray gun at 0.3 MPa, keeping the coating consistent without the pressure drift that would change the finish.
Is the Airtac GAR Air Regulator GAR40010L the Right Regulator?
Choose the GAR40010L when your downstream equipment needs a low, stable pressure between 0.05 and 0.4 MPa (7-58 psi) and you want the finer adjustment resolution the L type gives over that band. The 3/8in port suits medium air demand; step up to the GAR500 (580 g) with a 3/4in port for heavier flow, or down to the GAR300 (300 g) with a 1/4in or 3/8in port for lighter duty. The circular gauge is fitted and reads MPa/psi on the PT thread, and the mounting bracket is included. If the air also needs cleaning, use a GAFR400 or a separate GAF filter upstream, since this regulator does not filter. The L type's adjustable band is only 0.35 MPa wide, about 2.4x narrower than the standard S type's 0.85 MPa 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 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 GAR40010L FAQ
The GAR40010L is a lower-pressure regulator with a 3/8in port and a regulated range of 0.05-0.4 MPa (7-58 psi). Maximum supply pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and the temperature range is -20 to 70 C. The unit weighs 570 g and has a circular gauge fitted with an MPa/psi scale.
The L type regulates only from 0.05 to 0.4 MPa (7-58 psi), which is a lower band than the standard S type's 0.05-0.9 MPa range. The L type gives finer adjustment resolution over that low band, but it cannot reach a 0.5 or 0.6 MPa setpoint at all, so it is only suitable for low-pressure applications.
