Airtac GAR Air Regulator GAR40010LJNK
The AirTAC Airtac GAR Air Regulator GAR40010LJNK 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 GAR40010LJNK
The GAR40010LJNK is a regulator-only unit that takes a higher supply pressure and holds a steady, lower downstream pressure you set with the knob. It does not filter, clean, or dry the air - no drain bowl, no filter element, and no lubricator are present. This model uses a 3/8in port and weighs 570 g, placing it in the mid-size GAR400 class.
This lower-pressure (L) type regulates from 0.05-0.4 MPa (7-58 psi), offering finer resolution over that low band than a standard unit. The pressed-in self-locking knob prevents the setpoint from drifting due to vibration or accidental knocks, so a calibrated low-pressure setting stays put during a shift.

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
- GAR2001/8"-1/4" · 170 g
- 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 GAR40010LJNK Is Used
Low-pressure clamping circuit
Set a delicate 0.2 MPa clamp force on a fixture that holds thin-walled parts. The L type's finer low-band resolution lets you dial in a gentle, repeatable grip without over-pressuring the workpiece.
Lab air supply bench
Feed a stable 0.15 MPa supply to a pneumatic test rig or a sensitive instrument. The self-locking knob keeps the setpoint steady against bench vibration, so experiments see a consistent pressure.
Paint or coating spray gun
Regulate atomising air to a spray gun at 0.3 MPa for an even finish. The 3/8in port feeds the gun's demand, and the reflux valve is already fitted for the line configuration.
Is the Airtac GAR Air Regulator GAR40010LJNK the Right Regulator?
Choose the GAR400 body when you need a 3/8in port and a 570 g unit that suits a medium air demand. The L type is for low-pressure work only - it cannot reach a 0.5-0.6 MPa setpoint, so pick the standard S type if you need up to 0.9 MPa. This SKU omits the gauge (N), so read pressure on the line's own panel gauge, and it omits the bracket (J), so plan for a panel mount or an existing bracket. The PT thread reads MPa/psi on any fitted gauge. A reverse-flow (reflux) valve is attached (K). If the air also needs cleaning, use a GAFR400-10 or a GAF filter upstream. The L type's 0.05-0.4 MPa band is 0.35 MPa wide, while the S type spans 0.85 MPa - about 2.4x the adjustable range.
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 GAR40010LJNK FAQ
The GAR40010LJNK is a lower-pressure 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). The temperature range is -20 to 70 C. It has no gauge and no bracket, and it includes a reflux valve.
The N means no pressure gauge is fitted, so you read the downstream pressure on the line's own panel gauge. The J means the mounting bracket is omitted, so you need a panel mount or an existing bracket. The K indicates a reverse-flow (reflux) valve is attached to the unit.
