Airtac GAR Air Regulator GAR30008LJNK
The AirTAC Airtac GAR Air Regulator GAR30008LJNK 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 GAR30008LJNK
The GAR30008LJNK is an air pressure regulator that takes a higher supply and holds a steady downstream pressure you set with its knob. It is a regulator only - it does not filter the air or remove water, and it has no drain bowl or filter element. This unit has a 1/4in port and weighs 300 g, placing it in the mid-size GAR300 class for branch lines and individual machine stations.
This is the lower-pressure L type, regulating from 0.05-0.4 MPa (7-58 psi) with finer resolution across that low band than the standard type. A pressed-in self-locking knob keeps the setpoint from drifting when the machine vibrates, so a calibrated low-pressure setting stays put during a shift. The gauge is omitted, so pressure is read 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 GAFR300 filter-regulator or add a GAF filter upstream. Never run above the 1.5 MPa (215 psi) proof pressure.

| L | Lower pressure regulation: 0.05 - 0.4 MPa (7 - 58 psi). This body offers S (standard) or L (lower pressure). |
| J | No bracket (J) — panel mount or existing bracket. |

A GAR regulates pressure but does not filter — there is no bowl, element or drain code. Need to clean the air too? The matching GAFR300-08 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 GAR30008LJNK Is Used
Low-pressure air bearing supply
Feed a precision air bearing or air slide that needs a stable 0.1-0.3 MPa supply. The L type's finer low-band resolution holds the setpoint closer than a standard regulator would.
Lab pneumatic control
Set a gentle 0.2 MPa for a laboratory fixture or test rig. The self-locking knob keeps the pressure from drifting when nearby pumps or compressors vibrate the bench.
Delicate blow-off nozzle
Regulate a low-pressure blow-off for cleaning sensitive parts or optics. The 1/4in port feeds a single nozzle, and the reflux valve is fitted for reverse-flow lines.
Is the Airtac GAR Air Regulator GAR30008LJNK the Right Regulator?
Choose the GAR300 body for 1/4in or 3/8in branch lines where a compact 300 g regulator mounts near the point of use; step up to the GAR400 (570 g) for larger 3/8in-1/2in flows. The L type regulates only 0.05-0.4 MPa (7-58 psi), so it suits low-pressure work like air bearings or delicate blow-off, but it cannot reach a 0.5-0.6 MPa setpoint - pick the S type for standard machine pressures. This code has no gauge (N) and no bracket (J), so plan a panel mount or use the line's existing gauge; the thread is PT with an MPa/psi scale. A reverse-flow (reflux) valve is attached (K). If the air also needs cleaning, use a GAFR300-08 or a GAF filter upstream, since this regulator does not filter. The standard S type's 0.05-0.9 MPa band is about 2.4x this L type's adjustable 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 GAFR300
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 300 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 GAFR300-08 filter-regulator as your air-prep needs grow.
Airtac GAR Air Regulator GAR30008LJNK FAQ
The GAR30008LJNK is a regulator-only unit with a 1/4in port and a weight of 300 g. It regulates air 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, no bracket, a PT thread, and a reflux valve attached.
The N in the code 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 mount it directly to a panel or use an existing bracket. This saves cost when you already have those components in your system.
