Airtac GAR Air Regulator GAR20008LJK
The AirTAC Airtac GAR Air Regulator GAR20008LJK 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 built-in circular pressure gauge. It regulates pressure only — it does not filter the air or remove water.

About the Airtac GAR Air Regulator GAR20008LJK
The GAR20008LJK is an air pressure regulator that takes a higher supply and holds a steady lower downstream pressure, set by its knob and read on the fitted circular gauge. It does not filter, clean, or dry the air, and has no drain bowl or filter element.
This lower-pressure (L) model regulates from 0.05 to 0.4 MPa (7-58 psi), with a 1/4in port and a 170 g body. Its pressed-in self-locking knob resists drift from vibration, while the balanced adjustment mechanism keeps the setpoint stable as supply pressure varies.

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.

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 GAR20008LJK Is Used
Low-pressure clamping
Set a gentle, repeatable 0.1 MPa for a delicate workpiece clamp on a small bench fixture, where the L type's finer low-band resolution prevents over-force.
Lab air supply
Feed a 1/4in line to a laboratory pneumatic actuator that needs a stable 0.2 MPa, isolated from supply swings in the plant air system.
Paint spray gun feed
Hold a steady low pressure for a touch-up spray gun, using the fitted gauge to verify the setpoint and the self-locking knob to keep it fixed.
Is the Airtac GAR Air Regulator GAR20008LJK the Right Regulator?
Choose the body and port to match your line size: this GAR200 uses a 1/4in port and is the lightest body at 170 g, while the GAR300 (300 g) offers 1/4in to 1/2in ports for higher flow demand. The L type regulates only 0.05-0.4 MPa (7-58 psi), so it suits low-pressure tasks but cannot reach a 0.5-0.6 MPa setpoint; pick the S type for standard 0.05-0.9 MPa work. The circular gauge is fitted and reads MPa/psi on the PT thread, the J code omits the mounting bracket for panel mounting, and the K code attaches a reverse-flow (reflux) valve. If the line also needs clean air, use a GAFR filter-regulator or a GAF filter upstream. The S type's 0.05-0.9 MPa band is about 2.4x wider than this L type's 0.05-0.4 MPa span.
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 GAR20008LJK FAQ
The GAR20008LJK is a lower-pressure regulator with a 1/4in port, regulating from 0.05 to 0.4 MPa (7-58 psi). Maximum supply pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), temperature range is -20 to 70 C, and it weighs 170 g. It has a fitted circular gauge, no bracket, and a reflux valve.
The L type regulates only 0.05-0.4 MPa (7-58 psi), giving finer resolution over that low band compared to the standard S type, but it cannot reach higher setpoints. The K code means a reverse-flow (reflux) valve is attached to the unit.
