Airtac B52-GAR Copper-Free Air Source Treatment Unit B52-GAR60025S
The AirTAC Airtac B52-GAR Copper-Free Air Source Treatment Unit B52-GAR60025S 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" ports and a built-in circular pressure gauge. It regulates pressure only — it does not filter the air or remove water.

About the Airtac B52-GAR Copper-Free Air Source Treatment Unit B52-GAR60025S
The AirTAC GAR60025S 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, and it has no drain bowl or filter element. This model uses a 1in port and weighs 1390 g, placing it at the top of the GAR size range for high-demand lines.
Its pressed-in self-locking knob keeps the set pressure from drifting when the machine vibrates, so a calibrated setting stays put during a shift. The circular gauge with clip and magnifier is fitted and reads in MPa/psi, matching the PT thread standard. The balanced adjustment mechanism also holds the setpoint as supply pressure varies, protecting downstream equipment from swings.

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 GAFR600 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 GAFR600-25 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 B52-GAR Copper-Free Air Source Treatment Unit B52-GAR60025S Is Used
Machine header pressure
Set a stable 0.4 MPa header for a multi-station assembly machine where several pneumatic actuators share one supply line. The 1in port handles the combined demand without starving any station.
Calibrated test rig
Hold a precise 0.6 MPa for a leak-test fixture that needs a repeatable pressure across many cycles. The self-locking knob keeps the setting stable during long test runs.
Conveyor tension control
Regulate air to a pneumatic tensioner on a long conveyor belt, keeping the belt taut as the line speed changes. The balanced design holds the setpoint against supply fluctuations.
Is the Airtac B52-GAR Copper-Free Air Source Treatment Unit B52-GAR60025S the Right Regulator?
Choose the GAR60025S when your line needs a 1in port and a high air demand, as this 1390 g body is the largest in the GAR family. The standard S type regulates from 0.05-0.9 MPa, which covers most industrial setpoints, and the included bracket supports the heavy body on a panel or frame. The fitted gauge shows MPa/psi, and the PT threads suit standard piping. If you also need clean air, pair this with a GAF600 filter upstream or use a GAFR600 filter-regulator instead. The S type's adjustable band is about 2.4x the L type's span, giving you a wider range of setpoints for general machinery.
Quick checklist
- ✓ Body size for your air demand (1" 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 GAFR600
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 1390 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 GAFR600-25 filter-regulator as your air-prep needs grow.
Airtac B52-GAR Copper-Free Air Source Treatment Unit B52-GAR60025S FAQ
The GAR60025S is a regulator-only unit with a 1in port and a weight of 1390 g. It regulates from 0.05-0.9 MPa (7-130 psi), with a max supply pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The temperature range is -20 to 70 C. It has a circular gauge fitted and an included mounting bracket.
No, the GAR60025S is a regulator only. It does not filter, clean, or remove water or particles from the air. It has no drain bowl or filter element. For clean air, install a separate GAF600 filter upstream or use a GAFR600 filter-regulator, which combines both functions in one body.
