Airtac GAR Air Regulator GAR40010SK
The AirTAC Airtac GAR Air Regulator GAR40010SK is a genuine compressed-air pressure regulator. It sets and holds a steady downstream pressure across the 0.05 - 0.9 MPa range, with 3/8" 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 GAR40010SK
The GAR40010SK is an air pressure regulator that takes a higher supply pressure and holds a steady, lower downstream pressure you set with the knob and read on the circular gauge. It does not filter or clean the air and has no drain bowl or filter element. This 3/8" port model weighs 570 g and regulates the standard 0.05-0.9 MPa (7-130 psi) band.
The pressed-in self-locking knob keeps the set pressure from drifting when the machine vibrates, so a clamp or tool holds its force through a shift. The balanced adjustment mechanism also holds the setting as the supply pressure varies. A reverse-flow (reflux) valve is attached to this unit.

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 GAFR400-10 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 GAR40010SK Is Used
Machine tool pressure setting
Set a steady 0.4 MPa for an air vise on a drill press. The self-locking knob keeps the grip force constant through a production run, and the gauge confirms the setpoint at a glance.
Pneumatic conveyor tensioning
Regulate the air feeding a belt tensioner on a packaging line. The balanced design holds the downstream pressure even when the plant supply fluctuates, so the belt stays taut.
Test bench air supply
Provide a stable 0.6 MPa to a leak-test fixture. The 3/8" port feeds the fixture's valves, and the 570 g body mounts solidly on the bench panel with the included bracket.
Is the Airtac GAR Air Regulator GAR40010SK the Right Regulator?
Choose the GAR400 body when a 3/8" port feeds a medium air demand; step up to the GAR500 at 580 g for a 3/4" line or down to the GAR300 at 300 g for 1/4" to 1/2" ports. This standard S type regulates 0.05-0.9 MPa (7-130 psi), while the L type only reaches 0.4 MPa and cannot set a 0.5 MPa point. The circular gauge reads MPa/psi on its PT thread, the mounting bracket is included, and the K option adds a reflux valve. If the line also needs clean air, use the matching GAFR400-10 filter-regulator or a GAF filter upstream. The S type's adjustable band is about 2.4x the L type's span.
Quick checklist
- ✓ Body size for your air demand (3/8" 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 GAFR400-10 filter-regulator as your air-prep needs grow.
Airtac GAR Air Regulator GAR40010SK FAQ
The GAR40010SK is a standard-type air pressure regulator with a 3/8" port and a regulated range of 0.05-0.9 MPa (7-130 psi). Maximum supply pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). It operates from -20 to 70 C and weighs 570 g. The circular gauge reads MPa/psi and the mounting bracket is included.
The K indicates a reverse-flow (reflux) valve is attached to the regulator. This unit includes that valve. It does not change the regulated pressure range or the port size, and the regulator still does not filter the air.
