Airtac GAR Air Regulator GAR40015LNK
The AirTAC Airtac GAR Air Regulator GAR40015LNK 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 GAR40015LNK
The GAR40015LNK is an air pressure regulator that takes a higher supply and holds a steady lower downstream pressure you set with the knob. It is a regulator only - it does not filter, clean, or dry the air, and has no drain bowl or filter element. This 1/2in model weighs 570 g and uses the lower-pressure type, regulating from 0.05-0.4 MPa (7-58 psi) for fine control in that low band.
A pressed-in self-locking mechanism keeps the set pressure from drifting when the machine vibrates, so a clamp or tool holds its force cycle after cycle. The balanced adjustment design also holds the setpoint as supply pressure varies. With no gauge fitted, you read the 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 GAFR400-15 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 GAR40015LNK Is Used
Low-pressure clamping
Set a gentle, repeatable grip on fragile parts in an assembly fixture. The L type's fine low-band control keeps force steady without crushing the workpiece.
Lab air supply
Feed a sensitive pneumatic instrument or test rig that needs a stable low pressure. The self-locking knob holds the setting despite nearby pump vibration.
Painting or coating line
Regulate air for a spray application where consistent low pressure matters. The 1/2in port feeds a single station, while the bracket mounts it securely to the panel.
Is the Airtac GAR Air Regulator GAR40015LNK the Right Regulator?
Choose the GAR400 body when you need a 1/2in port and the 570 g mass tells you it suits a fixed machine station rather than handheld work. The L type regulates only 0.05-0.4 MPa (7-58 psi), so pick it only for low-pressure tasks like delicate gripping; it cannot reach a 0.5-0.6 MPa setpoint at all. This unit keeps the mounting bracket and uses PT threads with an MPa/psi gauge scale, but has no gauge fitted - the N means you read pressure on your panel gauge. The K adds a reverse-flow (reflux) valve, named here without describing its function. If the line also needs clean air, use the matching GAFR400-15 or a separate GAF filter upstream, since this regulator does not clean the air. The S type's adjustable band spans about 2.4x this L type's range (0.85 MPa vs 0.35 MPa).
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 GAR40015LNK FAQ
It is an air pressure regulator with a 1/2in port and a 570 g weight. The lower-pressure type regulates from 0.05-0.4 MPa (7-58 psi). Maximum supply pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). Operating temperature is -20 to 70 C. It has no gauge fitted, includes the mounting bracket, uses PT threads, and has a reverse-flow (reflux) valve attached.
The N means no pressure gauge is fitted, so you read the downstream pressure on the line's own panel gauge. The K means a reverse-flow (reflux) valve is attached to the regulator; our data names this option but does not describe its function. This is a regulator only - it does not filter or clean the air, so pair it with a GAF or GAFR if you need filtration.
