Airtac GAR Air Regulator GAR30015S
The AirTAC Airtac GAR Air Regulator GAR30015S is a genuine compressed-air pressure regulator. It sets and holds a steady downstream pressure across the 0.05 - 0.9 MPa range, with 1/2" ports and a built-in circular pressure gauge. It regulates pressure only — it does not filter the air or remove water.

About the Airtac GAR Air Regulator GAR30015S
The GAR30015S is an air pressure regulator that takes a higher supply pressure and holds a steady, lower downstream pressure you set with the knob and read on the circular gauge. It does not filter the air or remove water; it only regulates pressure. This unit has a 1/2in port and weighs 300 g, placing it in the mid-size class for shop air lines.
The pressed-in self-locking knob prevents the set pressure from drifting due to vibration or accidental knocks, so your downstream tools see a consistent pressure. The balanced adjustment mechanism also helps the regulator hold its setting as the supply pressure varies. The circular gauge with clip and magnifier saves panel space while remaining easy to read.

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.

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 GAR30015S Is Used
Machine tool pressure setting
Set a stable 0.4 MPa supply for a CNC clamp circuit or a pneumatic fixture on a machining center. The 1/2in port feeds moderate air demand while the self-locking knob keeps the setpoint from drifting during heavy vibration.
Assembly line workstations
Regulate pressure for multiple hand tools or air nozzles at a single assembly station. The 300 g body mounts easily on a panel or bracket, and the circular gauge lets operators verify the set pressure at a glance.
Test rig and bench setups
Provide a controlled air supply for prototype testing or calibration benches where a steady downstream pressure is critical. The balanced design holds the setpoint as the shop supply fluctuates during peak demand.
Is the Airtac GAR Air Regulator GAR30015S the Right Regulator?
Choose the GAR30015S when you need a 1/2in port and a standard 0.05-0.9 MPa (7-130 psi) regulated range. The S type covers the full common band for most pneumatic tools and machines; if you only need low pressures up to 0.4 MPa, an L type would offer finer resolution but cannot reach higher setpoints. The mounting bracket is included, and the circular gauge is fitted with an MPa/psi scale for PT threads. If your line also needs clean air, pair this with a GAF filter upstream or use the matching GAFR300-15 filter-regulator instead. The S type's adjustable band of 0.85 MPa is about 2.4x the L type's 0.35 MPa span, giving you far more setpoint flexibility.
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 GAR30015S FAQ
The GAR30015S regulates air from 0.05 to 0.9 MPa (7-130 psi). Maximum supply pressure is 1.0 MPa (145 psi), and proof pressure is 1.5 MPa (215 psi). Operating temperature range is -20 to 70 C. The unit weighs 300 g and has a 1/2in port. It includes a mounting bracket and a circular pressure gauge with an MPa/psi scale.
No. The GAR30015S is a regulator only; it does not filter, clean, or dry the air, and it has no filter element or drain bowl. If your application needs clean air, install a GAF filter upstream or use the GAFR300-15 filter-regulator which combines both functions in one body.
