Airtac GAR Air Regulator GAR40015LN
The AirTAC Airtac GAR Air Regulator GAR40015LN is a genuine compressed-air pressure regulator. It sets and holds a steady downstream pressure across the 0.05 - 0.4 MPa range, with 1/2" 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 GAR40015LN
The GAR40015LN is a regulator-only unit that takes a higher supply pressure and holds a steady lower downstream pressure you set with its knob. It does not filter or clean the air, so any water or particles in the line must be handled by a separate filter upstream.
This model has a 1/2in port and weighs 570 g, placing it in the mid-size GAR400 class. It is the lower-pressure L type, regulating from 0.05-0.4 MPa (7-58 psi), and comes without a gauge so you read pressure on the line's own panel gauge. The pressed-in self-locking knob keeps the setpoint from drifting due to vibration.

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 GAFR400-15 is the same regulator with a built-in filter.
Size Class

- GAR3001/4"-1/2" · 300 g

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 GAR40015LN Is Used
Precision low-pressure clamping
Set a delicate 0.2 MPa clamp force on a light assembly fixture where a standard regulator would risk over-pressuring the part.
Lab air supply regulation
Hold a stable 0.3 MPa supply for a laboratory pneumatic actuator that needs a gentle, repeatable force without a gauge on the unit.
Paint or coating line feed
Maintain a low 0.15 MPa pressure for a small spray gun in a finishing station, using the line's own panel gauge for setup.
Is the Airtac GAR Air Regulator GAR40015LN the Right Regulator?
Choose the GAR400 body when you need a 1/2in port and a 570 g unit that suits medium air demand. The L type regulates only 0.05-0.4 MPa (7-58 psi), so it cannot reach a 0.5-0.6 MPa setpoint; pick the standard S type if you need up to 0.9 MPa. This model has no gauge (N), so rely on an existing panel gauge, and the mounting bracket is included. The PT thread gives a gauge scale reading MPa/psi. If the line also needs clean air, use the matching GAFR400-15 or a GAF filter upstream. The S type's 0.05-0.9 MPa band spans about 2.4x this L type's 0.05-0.4 MPa range.
Quick checklist
- ✓ Body size for your air demand (1/2" 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 GAFR400-15 filter-regulator as your air-prep needs grow.
Airtac GAR Air Regulator GAR40015LN FAQ
The GAR40015LN is an AirTAC regulator-only unit with a 1/2in port and a weight of 570 g. It regulates air from 0.05-0.4 MPa (7-58 psi), with a maximum supply pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It operates in temperatures from -20 to 70 C and has no gauge fitted.
The N in GAR40015LN means no gauge is included, so you read the downstream pressure on the line's own panel gauge instead. The L type is the lower-pressure version, regulating only 0.05-0.4 MPa (7-58 psi) for finer control in that low band; it cannot reach higher setpoints like 0.6 MPa.
