Airtac GAR Air Regulator GAR20008LJN
The AirTAC Airtac GAR Air Regulator GAR20008LJN 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 GAR20008LJN
The GAR20008LJN is a compact air pressure regulator that takes a higher supply pressure and holds a steady, lower downstream pressure you set with the knob. It does not filter or clean the air, and it has no drain bowl or filter element - it only regulates pressure.
This unit has a 1/4in port and weighs 170 g, placing it in the small GAR200 size class. It is the lower-pressure L type, regulating from 0.05-0.4 MPa (7-58 psi), which gives finer resolution over that low band. The pressed-in self-locking knob prevents the set pressure from drifting due to vibration or accidental knocks.

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 GAR20008LJN Is Used
Low-pressure clamping
Set a gentle, repeatable clamp force on a small fixture or work-holder. The L type's finer low-band resolution keeps delicate parts from being over-stressed.
Lab air supply
Feed a sensitive pneumatic instrument or test rig that needs a stable, low-pressure air supply. The balanced design holds the setpoint as the shop supply fluctuates.
Single tool pressure
Protect one air tool or a small cylinder from supply swings. The self-locking knob keeps the pressure where you set it, even with vibration from the tool.
Is the Airtac GAR Air Regulator GAR20008LJN the Right Regulator?
Choose the GAR20008LJN when you need a small regulator for a 1/4in line and your setpoint stays below 0.4 MPa. The L type cannot reach a 0.5-0.6 MPa setpoint, so for standard machine pressures pick the S type instead. This model has no gauge, so read pressure on the line's own panel gauge, and it comes without a bracket - use a panel mount or existing bracket. The PT thread connects with MPa/psi gauge scales. If the air also needs cleaning, use a GAFR200-08 filter-regulator or a separate GAF filter upstream. The standard S type spans about 2.4x this L type's adjustable band (0.85 MPa vs 0.35 MPa).
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 GAR20008LJN FAQ
The GAR20008LJN is a lower-pressure regulator with a 1/4in port. 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). It operates from -20 to 70 C and weighs 170 g. It has no gauge and no mounting bracket.
The 'N' in the code means no pressure gauge is fitted. You read the downstream pressure on the line's own panel gauge instead. This saves cost and panel space when a gauge is already present in the system.
