Airtac GAR Air Regulator GAR40010SJN
The AirTAC Airtac GAR Air Regulator GAR40010SJN 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 GAR40010SJN
The GAR40010SJN is an air pressure regulator that takes a variable supply and holds a steady downstream pressure you set with the knob. It does not filter or clean the air, and it has no drain bowl or filter element - it only regulates pressure. This unit uses a 3/8in port and weighs 570 g, placing it in the mid-size class for shop and machine lines.
This standard-type model regulates from 0.05-0.9 MPa (7-130 psi). The pressed-in self-locking knob prevents the setpoint from drifting when the machine vibrates, so a calibrated pressure stays put through a shift. With no gauge fitted, you read pressure on the line's own panel gauge instead.

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.
Size Class

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 GAR40010SJN Is Used
Machine tool pressure set
Set a stable 0.4 MPa for a CNC clamp circuit where the supply swings with other loads. The balanced valve holds the setpoint as inlet pressure varies, keeping clamp force consistent.
Pneumatic bench supply
Feed a workbench manifold at 0.6 MPa for multiple hand tools. The 3/8in port handles moderate air demand, and the self-locking knob keeps the setting from drifting with bench vibration.
Test rig regulation
Regulate a test fixture at 0.3 MPa where repeatability matters. Without a gauge on the unit, use the panel gauge to verify pressure, and rely on the balanced design for stable output.
Is the Airtac GAR Air Regulator GAR40010SJN the Right Regulator?
Choose the GAR40010SJN when you need a 3/8in regulated supply without a gauge or bracket. The J code means no mounting bracket is included, so plan for a panel mount or use an existing bracket; the N code means no pressure gauge, so rely on a line gauge. This is the standard S type with a 0.05-0.9 MPa (7-130 psi) band, which suits most industrial actuators and tools. The PT thread reads MPa/psi on any gauge you fit. If the air also needs cleaning, use a GAFR400 filter-regulator or a GAF filter upstream - this unit does not filter. The S type's adjustable band is about 2.4x the L type's (0.85 MPa vs 0.35 MPa), giving you a much wider setpoint range.
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 GAR40010SJN FAQ
The GAR40010SJN regulates air from 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 with a 3/8in port. It has no gauge and no bracket.
The N code means no pressure gauge is fitted, so you read pressure on the line's own panel gauge. The J code means no mounting bracket is included, so you use a panel mount or an existing bracket. This saves cost when you already have these components in your system.
