Airtac GAR Air Regulator GAR30015LNK
The AirTAC Airtac GAR Air Regulator GAR30015LNK 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 GAR30015LNK
The GAR30015LNK is an air pressure regulator that takes a higher supply and holds a steady lower downstream pressure, set by the knob and read on the line's own panel gauge since this unit ships without one. It regulates pressure only - it does not filter, clean, dry, or remove water, oil, or particles from the air.
This lower-pressure (L) model regulates from 0.05-0.4 MPa (7-58 psi), with a 1/2in port and a 300 g body. The pressed-in self-locking knob prevents the set pressure from drifting due to vibration or accidental knocks, while the balanced adjustment mechanism holds the setting as supply pressure varies.

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 GAFR300 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 GAFR300-15 is the same regulator with a built-in filter.
Size Class
- GAR2001/8"-1/4" · 170 g
- 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 GAR30015LNK Is Used
Low-Pressure Clamping
Set a precise 0.2 MPa for a delicate clamping circuit on an assembly bench, where the 1/2in port feeds multiple small pneumatic fixtures without over-pressuring them.
Paint or Coating Lines
Regulate atomizing air to a spray gun at 0.15 MPa, keeping the coating consistent even when the main supply fluctuates, since the balanced valve holds the setpoint.
Lab Pneumatic Circuits
Supply a test rig with a stable 0.3 MPa for air bearings or sensors, where the lower range and fine adjustment prevent accidental over-pressure to sensitive equipment.
Is the Airtac GAR Air Regulator GAR30015LNK the Right Regulator?
Choose the GAR300 body when you need a 1/2in port and a 300 g unit; step down to a GAR200 (170 g) for 1/8in-1/4in ports, or up to a GAR400 (570 g) for 3/8in-1/2in ports with a heavier body. The L type regulates only 0.05-0.4 MPa (7-58 psi), so it suits low-pressure circuits but cannot reach a 0.5-0.6 MPa setpoint - for standard machine pressures, select the S type instead. This model has no gauge (N), so use the line's panel gauge; the mounting bracket is included, and the PT thread reads MPa/psi on any fitted gauge. A reverse-flow (reflux) valve is attached (K). If the line also needs clean air, use a GAFR300-15 or a GAF filter upstream, as this regulator does not filter. The L type's adjustable band of 0.35 MPa is about 2.4x narrower than the S type's 0.85 MPa span, giving finer resolution over low pressures.
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 GAFR300
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 300 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 GAFR300-15 filter-regulator as your air-prep needs grow.
Airtac GAR Air Regulator GAR30015LNK FAQ
The GAR30015LNK is a lower-pressure regulator with a 1/2in port, regulating from 0.05-0.4 MPa (7-58 psi). Maximum supply pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and the temperature range is -20 to 70 C. The unit weighs 300 g, has no gauge, includes a mounting bracket, and uses PT threads.
The N option means no circular pressure gauge is fitted, so you read the pressure on the line's own panel gauge instead. The K option indicates a reverse-flow (reflux) valve is attached to the regulator. This model includes the mounting bracket and uses PT threads with an MPa/psi gauge scale if one is added.
