Airtac GAR Air Regulator GAR50020LNK
The AirTAC Airtac GAR Air Regulator GAR50020LNK is a genuine compressed-air pressure regulator. It sets and holds a steady downstream pressure across the 0.05 - 0.4 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 GAR50020LNK
The GAR50020LNK is an air pressure regulator that takes a higher supply and holds a steady lower downstream pressure, set by its knob. It is a regulator only - it does not filter, clean, or dry the air, and has no drain bowl or filter element. This unit carries a 3/4in port and weighs 580 g, placing it in the GAR500 size class for medium-flow lines.
Its lower-pressure (L) type regulates from 0.05-0.4 MPa (7-58 psi), which suits low-pressure circuits that need fine control. The pressed-in self-locking knob prevents the setpoint from drifting due to vibration or accidental contact. With no gauge fitted (N), you read pressure on the line's own panel gauge instead of a local one.

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 GAFR500 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 GAFR500-20 is the same regulator with a built-in filter.
Size Class

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 GAR50020LNK Is Used
Low-pressure clamping circuits
Set a gentle, repeatable clamp force on a fixture that must not crush a delicate part. The L type's 0.05-0.4 MPa range gives finer adjustment in that low band, and the 3/4in port feeds multiple small cylinders at once.
Pneumatic bench press
Regulate the air feeding a small bench press so each stroke applies the same force. The self-locking knob holds the setting through repeated cycles, and the included bracket mounts the 580 g unit securely to the frame.
Spray or blow-off station
Control a blow-off nozzle or spray gun to a low, consistent pressure. The 3/4in port supports the air demand of a multi-nozzle setup, while the no-gauge design suits lines where a central panel gauge already monitors pressure.
Is the Airtac GAR Air Regulator GAR50020LNK the Right Regulator?
Choose the GAR500 body for a 3/4in port and 580 g mass, stepping up from the GAR400 at 570 g when you need a larger connection for higher air demand. The L type regulates only 0.05-0.4 MPa (7-58 psi), so it cannot reach a 0.5-0.6 MPa setpoint - pick the standard S type if you need that range. This model has no gauge (N), so rely on a panel gauge; the mounting bracket is included, and the PT thread reads MPa/psi on any gauge you fit. The K code means a reverse-flow (reflux) valve is attached, named here without further detail. If the line also needs clean air, use a GAFR500-20 or a GAF filter upstream, since this regulator does not clean. The S type's 0.05-0.9 MPa band (0.85 MPa wide) spans about 2.4x this L type's 0.05-0.4 MPa band (0.35 MPa wide).
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 GAFR500
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 580 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 GAFR500-20 filter-regulator as your air-prep needs grow.
Airtac GAR Air Regulator GAR50020LNK FAQ
The GAR50020LNK is a lower-pressure (L) regulator with a 3/4in port and 580 g weight. It regulates from 0.05-0.4 MPa (7-58 psi), with a max supply pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -20 to 70 C. It has no gauge (N), includes a mounting bracket, uses PT thread, and has a reflux valve (K) attached.
The N in the code means no gauge is fitted, so you read the downstream pressure on the line's own panel gauge or an inline gauge you install. This saves panel space and cost when a local readout is not needed. The PT thread means any gauge you add reads in MPa/psi.
