Airtac GAR Air Regulator GAR20008SJN
The AirTAC Airtac GAR Air Regulator GAR20008SJN 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 GAR20008SJN
The GAR20008SJN is an 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, clean, dry, or remove water or particles from the air - it only regulates pressure.
This compact unit has a 1/4in port and weighs just 170 g, making it ideal for tight spaces. It is the standard type, regulating from 0.05-0.9 MPa (7-130 psi), with a maximum supply of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). 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 GAR20008SJN Is Used
Single Clamp Force
Set a precise, repeatable pressure for a small pneumatic clamp on a benchtop assembly fixture. The self-locking knob holds the setting despite machine vibration.
Bench Tool Supply
Feed a consistent 0.4 MPa to a small air tool or blow gun, protecting it from supply swings. The compact 170 g body mounts directly on a panel near the work area.
Test Rig Setpoint
Maintain a stable pressure for a laboratory test jig or a calibration setup where supply fluctuations would skew results. The balanced design holds the setpoint as inlet pressure varies.
Is the Airtac GAR Air Regulator GAR20008SJN the Right Regulator?
Choose the GAR20008SJN for small, individual pneumatic devices like a single clamp or a bench-top tool that needs a stable, lower pressure. This model has no mounting bracket (J) and no gauge (N), so plan for panel mounting and read pressure on the line's own gauge. The PT thread reads MPa/psi on a gauge if you add one. If your air also needs cleaning, use a GAFR200-08 or a GAF filter upstream, as this regulator does not filter. The standard S type's adjustable band of 0.85 MPa is about 2.4x the span of the lower-pressure L type's 0.35 MPa band.
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 GAR20008SJN FAQ
The GAR20008SJN is a standard-type air pressure regulator with a 1/4in port. It regulates from 0.05-0.9 MPa (7-130 psi). Maximum supply pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). The operating temperature range is -20 to 70 C, and the unit weighs 170 g.
The 'N' in GAR20008SJN 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, allowing for direct panel mounting or use of an existing bracket. This saves space and cost when those features are already present in your system.
