Airtac GAR Air Regulator GAR20008SN
The AirTAC Airtac GAR Air Regulator GAR20008SN is a genuine compressed-air pressure regulator. It sets and holds a steady downstream pressure across the 0.05 - 0.9 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 GAR20008SN
The GAR20008SN 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 is a regulator only - it does not filter the air or remove water, so install a separate filter upstream if the line needs cleaning.
This standard-type unit regulates from 0.05 to 0.9 MPa (7-130 psi) and weighs just 170 g with its 1/4in ports. The pressed-in self-locking knob keeps your pressure setting from drifting when the machine vibrates, and the balanced valve design holds the setpoint 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 GAR20008SN Is Used
Single clamp control
Set a steady 0.4 MPa to a pneumatic clamp on a small assembly fixture. The self-locking knob holds the pressure even when the workcell vibrates.
Bench tool supply
Feed a blow gun or a small air tool at a stable 0.6 MPa from a shop line that fluctuates. The balanced design keeps the outlet pressure from drifting.
Prototype test rig
Regulate a test jig at 0.3 MPa for repeated actuator cycles. The 170 g body mounts directly to the panel with the included bracket.
Is the Airtac GAR Air Regulator GAR20008SN the Right Regulator?
Choose the GAR200 body for light-duty circuits with 1/4in piping, such as a single clamp or a small tool. The standard S type covers 0.05-0.9 MPa, while the L type only reaches 0.4 MPa - pick S unless you need fine control in that low band. This model has no gauge, so read pressure on the line's own panel gauge; the included bracket mounts it to a panel or frame. The PT thread suits metric installations, and its gauge scale reads MPa/psi if one is fitted. For clean air, use the matching GAFR200-08 filter-regulator or a GAF filter upstream. The S type's adjustable band is about 2.4x the L type's span (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 GAR20008SN FAQ
The GAR20008SN regulates air from 0.05 to 0.9 MPa (7-130 psi). Maximum supply pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and the temperature range is -20 to 70 C. The unit weighs 170 g and has 1/4in ports.
The N in GAR20008SN 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 separate gauge is already installed.
