Airtac GAR Air Regulator GAR40015SK
The AirTAC Airtac GAR Air Regulator GAR40015SK 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 GAR40015SK
The GAR40015SK is an air pressure regulator that takes a variable supply and holds a steady downstream pressure you set with the knob and read on the circular gauge. It does not filter or clean the air, and it has no drain bowl or filter element. This unit carries a 1/2in port and weighs 570 g, placing it in the mid-size GAR400 class for branch lines and individual machine stations.
The pressed-in self-locking knob resists vibration and accidental knocks, so the setpoint stays where you left it during production runs. The balanced adjustment mechanism also holds the setting as supply pressure fluctuates. A circular gauge with a clip and magnifier is fitted, reading MPa/psi, and the mounting bracket is included for panel installation.

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 GAR40015SK Is Used
Machine tool pressure set
Set a stable 0.4 MPa for a CNC clamp circuit or a pneumatic fixture, holding the workpieces firmly despite supply swings from other equipment on the same line.
Lab test rig supply
Feed a regulated 0.3 MPa to a test bench or calibration jig where a steady pressure is needed for repeatable readings, with the gauge giving a clear local readout.
Assembly station air
Supply a consistent pressure to pneumatic screwdrivers or nutrunners on an assembly line, preventing torque variation caused by upstream pressure drops.
Is the Airtac GAR Air Regulator GAR40015SK the Right Regulator?
Choose the GAR400 body when a 1/2in port matches your line demand; it sits between the GAR300 at 300 g for lighter duty and the GAR500 at 580 g for a 3/4in connection. The S type regulates 0.05-0.9 MPa (7-130 psi), covering standard machine pressures, while the L type would only reach 0.4 MPa and cannot serve a 0.5-0.6 MPa setpoint. The gauge is fitted and reads MPa/psi on the PT thread, and the mounting bracket is included. A reverse-flow (reflux) valve is attached to this unit. If the air also needs cleaning, use a GAFR400 or a separate GAF filter upstream, as this regulator does not filter. The S type's adjustable band of 0.85 MPa is about 2.4x the L type's 0.35 MPa span.
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 GAR40015SK FAQ
The GAR40015SK is a standard-type air pressure regulator with a 1/2in port and a weight of 570 g. It regulates from 0.05 to 0.9 MPa (7-130 psi), with a maximum supply pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The operating temperature range is -20 to 70 C. It has a circular gauge fitted, a mounting bracket included, and a reverse-flow (reflux) valve attached.
The K indicates that a reverse-flow (reflux) valve is attached to the regulator. This is a factory-fitted option on the unit. The GAR itself remains a regulator only, so it does not filter the air or remove moisture; for clean air, you would need a GAFR400 filter-regulator or a separate GAF filter upstream.
