Airtac GAR Air Regulator GAR30008LK
The AirTAC Airtac GAR Air Regulator GAR30008LK 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 GAR30008LK
The GAR30008LK is an air pressure regulator that takes a higher supply pressure and holds a steady, lower downstream pressure set with its knob and read on the fitted circular gauge. It does not filter the air or remove water, moisture, oil or particles, and has no drain bowl or filter element.
This model has a 1/4in port and weighs 300 g, placing it in the mid-size GAR300 class. It is the lower-pressure L type, regulating from 0.05-0.4 MPa (7-58 psi), with a pressed-in self-locking knob that stops the set pressure drifting from 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 GAFR300 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 GAFR300-08 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 GAR30008LK Is Used
Low-pressure clamping
Set a gentle, repeatable clamp force on a delicate workpiece where a standard 0.9 MPa regulator would apply too much pressure.
Lab air supply
Feed a stable 0.05-0.4 MPa supply to a laboratory bench tool or instrument that needs a precise low pressure.
Paint or spray system
Hold a consistent low pressure for a spray gun or atomizing nozzle where supply swings would ruin the finish.
Is the Airtac GAR Air Regulator GAR30008LK the Right Regulator?
Choose the GAR30008LK when your line needs a regulated low pressure between 0.05 and 0.4 MPa (7-58 psi) and a 1/4in port matches your piping. The L type gives finer resolution over this low band, but it cannot reach a 0.5-0.6 MPa setpoint, so it is the wrong part for a standard machine. The circular gauge is fitted and reads MPa/psi on the PT thread, and the mounting bracket is included. A reverse-flow (reflux) valve is attached to this unit. If the air must also be cleaned, use the matching GAFR300-08 or a GAF filter upstream, as this regulator does not filter. 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 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 GAR30008LK FAQ
The GAR30008LK regulates air from 0.05 to 0.4 MPa (7-58 psi). Maximum supply pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). It operates from -20 to 70 C and weighs 300 g with a 1/4in port.
The K indicates a reverse-flow (reflux) valve is attached to the regulator. This model also has a fitted circular gauge reading MPa/psi, an included mounting bracket, and a PT thread.
