Airtac GAR Air Regulator GAR40010SN
The AirTAC Airtac GAR Air Regulator GAR40010SN 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 GAR40010SN
The GAR40010SN is an air pressure regulator that takes a higher supply pressure and holds a steady, lower downstream pressure you set with the knob. It is a regulator only - it does not filter the air, remove water, or separate particles, and it has no drain bowl or filter element. This unit carries a 3/8in port, weighs 570 g, and is the standard type regulating 0.05-0.9 MPa (7-130 psi).
Its pressed-in self-locking knob prevents the set pressure from drifting due to vibration or accidental knocks, keeping your downstream equipment stable. The balanced adjustment mechanism holds the setpoint as supply pressure varies, so you get consistent output even with fluctuating inlet pressure. With no gauge fitted, you read the pressure on the line's own panel gauge.

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 GAR40010SN Is Used
CNC coolant control
Set a steady 0.4 MPa for coolant spray nozzles on a CNC lathe, keeping flow consistent despite supply swings from the compressor.
Pneumatic press feed
Regulate air to a small pneumatic press feeding mechanism, holding a repeatable force for stamping operations.
Test bench air supply
Provide a stable 0.6 MPa to a calibration test bench, ensuring instruments see a constant pressure during measurements.
Is the Airtac GAR Air Regulator GAR40010SN the Right Regulator?
Choose the GAR40010SN when your line needs a 3/8in port and a standard regulated range of 0.05-0.9 MPa (7-130 psi). The 570 g body sits between the lighter GAR300 at 300 g and the heavier GAR500 at 580 g, so it suits medium air demand. This model includes the mounting bracket and has no gauge (N), so you rely on an existing panel gauge. The PT thread reads MPa/psi on any gauge you fit. If you also need clean air, use a GAFR400-10 filter-regulator or a GAF filter upstream, since this unit does not filter. 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 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 GAR40010SN FAQ
The GAR40010SN regulates air from 0.05-0.9 MPa (7-130 psi) with a 3/8in port. 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. It has no gauge and includes a mounting bracket.
The N in the model code means no gauge is fitted. You read the downstream pressure on the line's own panel gauge instead, which saves cost and panel space if you already have a pressure display. The regulator still sets and holds pressure normally.
