Airtac GAR Air Regulator GAR40010S
The AirTAC Airtac GAR Air Regulator GAR40010S 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 GAR40010S
The GAR40010S 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 circular gauge. It does not filter or clean the air, and it has no drain bowl or filter element.
This model uses a 3/8in port and weighs 570 g, placing it in the mid-size class for shop air lines. The pressed-in self-locking knob keeps the setpoint from drifting when the machine vibrates, so a calibrated pressure stays put between shifts.

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 GAR40010S Is Used
CNC coolant valves
Set a steady 0.4 MPa to a coolant valve on a CNC lathe so the flow stays consistent even when the shop compressor cycles.
Assembly bench stations
Feed a regulated 0.3 MPa to pneumatic screwdrivers on an assembly bench, keeping torque repeatable across a shift.
Test rig air supply
Supply a controlled 0.6 MPa to a leak-test fixture, holding the test pressure stable while other equipment draws air.
Is the Airtac GAR Air Regulator GAR40010S the Right Regulator?
Choose this GAR40010S when your line needs a 3/8in port and a standard 0.05-0.9 MPa (7-130 psi) regulated range. The mounting bracket is included, and the fitted circular gauge reads MPa/psi. If you need clean air too, step up to the matching GAFR400-10 filter-regulator or add a GAF filter upstream, because this unit does not remove water or particles. The S type's adjustable band is about 2.4x the L type's span (0.85 MPa vs 0.35 MPa), giving you a wider setpoint window for general machinery.
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 GAR40010S FAQ
Regulated range is 0.05-0.9 MPa (7-130 psi). Max supply pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), temperature range is -20 to 70 C, and the unit weighs 570 g with a 3/8in port.
No. It is a regulator only and does not remove water, oil, or particles. For clean air, install a GAF filter upstream or use a GAFR400-10 filter-regulator instead.
