Airtac GAR Air Regulator GAR60020SNK
The AirTAC Airtac GAR Air Regulator GAR60020SNK 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 GAR60020SNK
The GAR60020SNK is a regulator-only unit that takes a higher supply pressure and holds a steady, lower downstream pressure you set with its knob. It does not filter or clean the air, and it has no drain bowl or filter element; for clean air you need a GAFR or a GAF upstream. This model uses a 3/4in port, weighs 1390 g, and is the standard type, regulating from 0.05-0.9 MPa (7-130 psi).
Its pressed-in self-locking knob keeps the set pressure from drifting when the machine vibrates, so a calibrated setting stays put during a shift. The balanced adjustment mechanism also holds the output steady as the supply pressure varies, protecting downstream components from swings. With no gauge fitted, you read the line's own panel gauge to confirm the setpoint.

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 GAR60020SNK Is Used
Machine header pressure
Set a steady 0.4 MPa for a stamping press header that feeds several pneumatic actuators, so each station sees the same force regardless of upstream supply swings.
Multi-station assembly line
Hold 0.6 MPa for a conveyor line with multiple pick-and-place units, keeping cycle times consistent even when other equipment draws air from the same source.
Paint spray booth supply
Regulate 0.3 MPa for a spray gun in a finishing booth, where a stable atomization pressure is needed for an even coat without over-spray.
Is the Airtac GAR Air Regulator GAR60020SNK the Right Regulator?
Choose the GAR600 body when your line needs a 3/4in port and the mass of a 1390 g unit, which suits a machine header or multi-station line rather than a small tool. The standard S type covers 0.05-0.9 MPa (7-130 psi), so it handles typical industrial setpoints; the L type would be limited to 0.05-0.4 MPa and cannot reach a 0.5 MPa setting. This model has no gauge (N), so rely on an existing panel gauge, and it includes the mounting bracket. The PT thread gives a gauge scale in MPa/psi, and the K option attaches a reverse-flow (reflux) valve, named here without describing its function. If the air also needs cleaning, step up to the matching GAFR600-20 filter-regulator or fit 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), giving you a wider range of setpoints from one regulator.
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 GAR60020SNK FAQ
This regulator-only unit has a 3/4in port and weighs 1390 g. It regulates air 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 no gauge fitted, includes a mounting bracket, uses PT threads, and comes with a reverse-flow (reflux) valve attached.
The N in the code means no pressure gauge is fitted to the regulator. You read the downstream pressure on the line's own panel gauge instead, which is useful when the regulator is mounted in a location where a local gauge would be hard to see or would duplicate an existing display. The PT thread still provides a scale of MPa/psi if you add a gauge later.
