Airtac GAR Air Regulator GAR60020SJN
The AirTAC Airtac GAR Air Regulator GAR60020SJN 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 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 GAR60020SJN
The AirTAC GAR60020SJN is a heavy-duty air pressure regulator that takes a variable supply and holds a steady, lower downstream pressure you set with its knob. It is a regulator only - it does not filter, clean, or remove water from the air, and it has no drain bowl or filter element. This model uses a 3/4in port and weighs 1390 g, placing it in the largest GAR size class for high-demand lines.
This standard-type unit regulates from 0.05-0.9 MPa (7-130 psi) and handles a maximum supply of 1.0 MPa (145 psi) with 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 contact, keeping your downstream equipment stable. Since this version has no gauge (N), you read the pressure on the line's own panel gauge instead.

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.

- GAR3001/4"-1/2" · 300 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 GAR60020SJN Is Used
Machine Header Pressure
Set a stable 0.5 MPa supply for a multi-station assembly machine header, ensuring consistent actuation across all pneumatic cylinders and tools despite upstream pressure swings.
High-Flow Test Bench
Regulate air for a high-flow test bench that checks large valves or actuators, holding a precise downstream pressure for repeatable pass-fail results.
Conveyor System Control
Maintain a steady pressure for a long conveyor line's air-driven tensioners and guides, preventing jams from pressure drops when multiple stations actuate at once.
Is the Airtac GAR Air Regulator GAR60020SJN the Right Regulator?
Choose the GAR600 body when you need to feed a machine header or a multi-station line with a 3/4in port and a 1390 g mass that requires a proper panel or bracket mount, not support from the tubing. This model omits the mounting bracket (J), so plan for a panel mount or use an existing bracket. The standard type (S) gives you a wide 0.05-0.9 MPa (7-130 psi) adjustment band, suitable for most industrial settings. With no gauge (N), you rely on the line's panel gauge for readouts, and the PT thread means the gauge scale reads in MPa/psi. If your air also needs cleaning, use a GAFR600-20 filter-regulator or a separate GAF filter upstream, as this GAR does not filter. 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 GAR60020SJN FAQ
The GAR60020SJN is a standard-type air pressure regulator with a 3/4in port. It regulates from 0.05-0.9 MPa (7-130 psi), has a max supply pressure of 1.0 MPa (145 psi), and a proof pressure of 1.5 MPa (215 psi). It operates in temperatures from -20 to 70 C and weighs 1390 g. This model has no gauge and no mounting bracket.
The N in the model code means no pressure gauge is fitted. This is for installations where the line already has a panel-mounted gauge or where the downstream pressure is monitored by a separate sensor. You read the set pressure on the line's own gauge instead of on the regulator body.
