Airtac GAR Air Regulator GAR40010SNK
The AirTAC Airtac GAR Air Regulator GAR40010SNK 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 no-gauge (N) port for a panel gauge. It regulates pressure only — it does not filter the air or remove water.

About the Airtac GAR Air Regulator GAR40010SNK
The GAR40010SNK is an air pressure regulator that takes a variable supply and holds a steady downstream pressure you set with its knob. It does not filter or clean the air, and it has no drain bowl or filter element - it only regulates pressure.
This standard-type unit suits 3/8" ports and weighs 570 g, placing it in the mid-size class. Its pressed-in self-locking knob prevents the setpoint from drifting due to vibration, so a calibrated pressure stays put during 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 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 GAR40010SNK Is Used
CNC coolant valve
Set a steady 0.4 MPa to a coolant valve on a milling center, keeping the spray consistent despite compressor swings.
Assembly station
Hold 0.3 MPa for a pneumatic screwdriver on a bench, so torque stays repeatable across a production run.
Test rig
Regulate a 0.7 MPa supply down to 0.2 MPa for a leak-test fixture, with the no-gauge design relying on a separate panel meter.
Is the Airtac GAR Air Regulator GAR40010SNK the Right Regulator?
Choose this GAR400 when your line uses 3/8" ports and needs a regulated range of 0.05-0.9 MPa. The standard S type covers the full band, while an L type would cap at 0.4 MPa and cannot reach a 0.5-0.6 MPa setpoint. This model has no gauge, so read pressure on the line's own panel gauge, and it includes the mounting bracket. The PT thread gives an MPa/psi gauge scale if you add one later. A reflux (K) valve is attached, and since this is a regulator only, fit a GAF or GAFR upstream if the air also needs cleaning. 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 (3/8" 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 GAR40010SNK FAQ
The GAR40010SNK regulates air from 0.05-0.9 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 570 g with a 3/8" port.
The N in the code means no gauge is fitted, so you read pressure on the line's own panel gauge instead. The K indicates a reverse-flow (reflux) valve is attached, which is named here but not detailed in our data.
