Airtac GAR Air Regulator GAR50020S
The AirTAC Airtac GAR Air Regulator GAR50020S 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 GAR50020S
The GAR50020S 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 gauge. It does not filter or dry the air, and it has no drain bowl or filter element - for clean air you need a GAFR or a GAF upstream.
This 3/4in model weighs 580 g and uses the standard pressure type, regulating from 0.05 to 0.9 MPa (7-130 psi). The pressed-in self-locking knob keeps the setpoint from drifting when the machine vibrates, so a calibrated pressure stays put through a shift.

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.

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 GAR50020S Is Used
Machine tool pressure setting
Set a steady 0.4 MPa for a clamping fixture on a CNC mill, where supply swings would otherwise change the clamp force and spoil the part.
Pneumatic conveyor tensioning
Hold a constant pressure for a belt tensioner on a packaging line, keeping the belt speed consistent despite drops in the plant air main.
Test bench air supply
Provide a repeatable 0.6 MPa for a leak-test fixture, so every part sees the same test pressure regardless of upstream fluctuations.
Is the Airtac GAR Air Regulator GAR50020S the Right Regulator?
Choose the GAR500 for a 3/4in line where a mid-size machine needs a stable regulated supply. The standard S type covers 0.05-0.9 MPa, while the L type would only reach 0.4 MPa and cannot serve a typical 0.5-0.6 MPa setpoint. The circular gauge reads MPa/psi on the PT thread, and the mounting bracket is included for panel installation. If the air also needs cleaning, step up to the matching GAFR500 filter-regulator instead. The S type's adjustable band is about 2.4x the L type's span (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 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 GAR50020S FAQ
The GAR50020S regulates air from 0.05 to 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). It operates from -20 to 70 C and weighs 580 g with a 3/4in port.
No, the GAR50020S is a regulator only and does not filter, clean, or remove water from the air. For filtration you need a separate GAF filter upstream or a GAFR500 filter-regulator that combines both functions in one body.
