Airtac GAR Air Regulator GAR20008LJNK
The AirTAC Airtac GAR Air Regulator GAR20008LJNK is a genuine compressed-air pressure regulator. It sets and holds a steady downstream pressure across the 0.05 - 0.4 MPa range, with 1/4" 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 GAR20008LJNK
The GAR20008LJNK is a compact air pressure regulator from AirTAC's GAR200 series, designed to take a higher supply pressure and hold a steady, lower downstream pressure that you set with its knob. It is a regulator only - it does not filter, clean, or dry the air, and it has no drain bowl or filter element. This unit weighs 170 g and has a 1/4 inch port, making it a lightweight choice for small pneumatic circuits.
This lower-pressure (L) model regulates from 0.05 to 0.4 MPa (7-58 psi), a band suited for delicate low-force tasks. The pressed-in self-locking knob prevents the set pressure from drifting due to vibration or accidental knocks, keeping your process stable. With no gauge fitted, you would read the pressure on the line's own panel gauge.

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 GAFR200 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 GAFR200-08 is the same regulator with a built-in filter.
Size Class
- GAR2001/8"-1/4" · 170 g
- GAR3001/4"-1/2" · 300 g

- GAR6003/4"-1" · 1390 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 GAR20008LJNK Is Used
Low-force clamping
Set a gentle, repeatable clamping pressure for fragile parts on a small assembly fixture, where a standard regulator's higher range would risk damage.
Lab air supply
Regulate air for a sensitive laboratory instrument or a pneumatic actuator on a test bench, holding a stable low pressure for accurate experiments.
Single tool pressure
Feed a small air tool or a spray gun with a consistent low pressure, preventing over-pressurization and improving control during detailed work.
Is the Airtac GAR Air Regulator GAR20008LJNK the Right Regulator?
Choose the GAR20008LJNK when you need precise low-pressure regulation in a small footprint. The 1/4 inch port and 170 g mass suit it for compact machines or individual tools; if you need more flow, step up to the GAR300 body at 300 g. This L type regulates 0.05-0.4 MPa (7-58 psi), so it cannot reach a 0.5-0.6 MPa setpoint - pick the S type for standard pressures. The J code means no mounting bracket is included, so plan for panel mounting or an existing bracket. The N code means no gauge is fitted; the PT thread reads MPa/psi if you add one. A reflux (K) valve is attached, and it is named here only. If your line also needs clean air, use a GAFR or a GAF filter upstream, as this unit does not filter. The L type's 0.35 MPa adjustable span is about 2.4x narrower than the S type's 0.85 MPa band.
Quick checklist
- ✓ Body size for your air demand (1/4" 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 GAFR200
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 170 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 GAFR200-08 filter-regulator as your air-prep needs grow.
Airtac GAR Air Regulator GAR20008LJNK FAQ
The GAR20008LJNK regulates air from 0.05 to 0.4 MPa (7-58 psi). Its maximum supply pressure is 1.0 MPa (145 psi), and its proof pressure is 1.5 MPa (215 psi). It operates in temperatures from -20 to 70 C and weighs 170 g. It has a 1/4 inch port, no gauge, no bracket, and a PT thread.
The 'L' type means it is a lower-pressure regulator, with a range of 0.05-0.4 MPa (7-58 psi), offering finer resolution over that low band compared to the standard type. The 'N' means no pressure gauge is fitted, so you would need to use a line gauge or install one to monitor the output pressure.
