Airtac GAR Air Regulator GAR40015S
The AirTAC Airtac GAR Air Regulator GAR40015S is a genuine compressed-air pressure regulator. It sets and holds a steady downstream pressure across the 0.05 - 0.9 MPa range, with 1/2" 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 GAR40015S
The GAR40015S 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 fitted circular gauge. It does not filter the air, remove water, or separate particles - it only regulates pressure.
This standard-type model regulates from 0.05-0.9 MPa (7-130 psi) with a 1/2in port and weighs 570 g. The pressed-in self-locking knob prevents the set pressure from drifting due to vibration or accidental contact, while the balanced adjustment mechanism maintains the setpoint as supply pressure varies.

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 GAFR400 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 GAFR400-15 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 GAR40015S Is Used
Machine Tool Pressure Setting
Set a stable 0.4 MPa for a CNC machine's pneumatic clamping fixture, ensuring consistent holding force across varying shop supply pressure.
Assembly Line Actuator Feed
Regulate air for multiple pneumatic cylinders on an assembly station, keeping actuation force steady despite pressure drops from other equipment.
Test Bench Supply Regulation
Provide a precise, adjustable pressure source for testing valves or cylinders on a workbench, with the gauge showing exact output pressure.
Is the Airtac GAR Air Regulator GAR40015S the Right Regulator?
Choose the GAR400 for 3/8in or 1/2in port lines where a 570 g body provides stable regulation for medium-demand equipment. The standard S type covers 0.05-0.9 MPa (7-130 psi), suitable for most industrial actuators and tools; the L type only reaches 0.4 MPa and cannot serve standard machines. The gauge is fitted with an MPa/psi scale for PT threads, and the mounting bracket is included. For clean air, pair this with a GAF filter upstream or choose the GAFR400-15 filter-regulator instead. This 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 (1/2" 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 GAFR400
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 570 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 GAFR400-15 filter-regulator as your air-prep needs grow.
Airtac GAR Air Regulator GAR40015S FAQ
The GAR40015S is a standard-type air pressure regulator with a 1/2in port and 570 g weight. It regulates from 0.05-0.9 MPa (7-130 psi), handles max supply pressure of 1.0 MPa (145 psi), and has a proof pressure of 1.5 MPa (215 psi). Operating temperature range is -20 to 70 C. It includes a circular gauge with MPa/psi scale and a mounting bracket.
No, the GAR40015S is a regulator only. It does not filter, clean, or remove water, oil, or particles from the air. It has no drain bowl or filter element. If you need clean air, install a GAF filter upstream or use a GAFR400-15 filter-regulator which combines both functions in one body.
