Airtac GAR Air Regulator GAR60020SJ
The AirTAC Airtac GAR Air Regulator GAR60020SJ is a genuine compressed-air pressure regulator. It sets and holds a steady downstream pressure across the 0.05 - 0.9 MPa range, with 3/4" 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 GAR60020SJ
The AirTAC GAR60020SJ is a regulator-only unit that takes a higher supply pressure and holds a steady, lower downstream pressure you set with the knob and read on the circular gauge. It does not filter or clean the air, has no drain bowl or filter element, and is not a filter-regulator.
This model uses a 3/4in port and weighs 1390 g, placing it in the largest GAR size class for heavy industrial lines. The pressed-in self-locking knob keeps the set pressure from drifting when the machine vibrates, and the balanced adjustment mechanism holds the setting as supply pressure varies. It regulates from 0.05-0.9 MPa (7-130 psi).

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 GAFR600 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 GAFR600-20 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 GAR60020SJ Is Used
Machine header pressure
Set a stable 0.4-0.6 MPa header for a multi-station machining center. The 3/4in port feeds several valves and actuators, and the self-locking knob holds the setpoint through vibration.
Multi-station assembly line
Regulate a common air rail feeding multiple workstations. The 1390 g body and 3/4in port handle the higher demand, while the balanced design keeps outlet pressure steady as other stations cycle.
Test rig supply
Provide a precise, adjustable test pressure for a hydraulic or pneumatic test bench. The circular gauge with magnifier makes reading the set pressure easy, and the PT thread matches standard local fittings.
Is the Airtac GAR Air Regulator GAR60020SJ the Right Regulator?
Choose the GAR60020SJ when your line needs a 3/4in port and the highest flow capacity in the GAR family. The 1390 g body is the size cue: it needs a solid panel or bracket mount, not support from the tubing. This is a standard (S) type, so it regulates 0.05-0.9 MPa; if you only need low pressures around 0.1-0.3 MPa, an L type would give finer resolution, but it cannot reach a 0.5 MPa setpoint. The J code means no mounting bracket is included, so plan for panel mounting or an existing bracket. The circular gauge is fitted and reads MPa/psi because the thread is PT. If the air also needs cleaning, use a GAFR600-20 or a separate GAF filter upstream. The S type's adjustable band is about 2.4x the L type's (0.85 MPa vs 0.35 MPa).
Quick checklist
- ✓ Body size for your air demand (3/4" 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 GAFR600
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 1390 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 GAFR600-20 filter-regulator as your air-prep needs grow.
Airtac GAR Air Regulator GAR60020SJ FAQ
The GAR60020SJ is a standard-type air pressure regulator with a 3/4in port and a weight of 1390 g. It regulates from 0.05-0.9 MPa (7-130 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 a circular gauge fitted (MPa/psi scale) and no mounting bracket (J code).
The J means the mounting bracket is NOT included. This model is intended for panel mounting or for use with an existing bracket. If you need the bracket, order the GAR60020S instead. The regulator itself functions identically either way.
