Airtac B52-GAR Copper-Free Air Source Treatment Unit B52-GAR30008L
The AirTAC Airtac B52-GAR Copper-Free Air Source Treatment Unit B52-GAR30008L is a genuine compressed-air pressure regulator. It sets and holds a steady downstream pressure across the 0.05 - 0.4 MPa range, with 1/4" 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-GAR30008L
The AirTAC GAR30008L is a regulator-only unit 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 or clean the air, and it has no drain bowl or filter element.
This lower-pressure model regulates from 0.05 to 0.4 MPa (7-58 psi) with a 1/4in port and a 300 g body. The pressed-in self-locking knob prevents the setpoint from drifting due to vibration or accidental knocks, keeping your downstream pressure stable.

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 GAFR300-08 is the same regulator with a built-in filter.
Size Class

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-GAR30008L Is Used
Precision pressure for small fixtures
Set a stable low pressure for pneumatic clamps or small work-holding fixtures on an assembly bench, where exact force matters more than high flow.
Lab air supply regulation
Feed a steady 0.1-0.3 MPa supply to laboratory air tools or test rigs that need a gentle, repeatable pressure without large fluctuations.
Low-pressure blow-off stations
Regulate a soft air blow-off for cleaning delicate parts or electronics, keeping the downstream pressure low to avoid damage.
Is the Airtac B52-GAR Copper-Free Air Source Treatment Unit B52-GAR30008L the Right Regulator?
Choose the GAR30008L when you need fine control in the low 0.05-0.4 MPa band, not the standard 0.05-0.9 MPa range. The 1/4in port suits small to medium air demand; step up to the GAR400 (570 g) for 3/8in or 1/2in ports if you need higher flow capacity. The circular gauge is fitted and reads MPa/psi, the bracket is included, and the thread is PT. If your line also needs clean air, use a GAFR300-08 or a GAF filter upstream, since this regulator does not filter. The L type's 0.35 MPa adjustable span is about 2.4x narrower than the S type's 0.85 MPa span, giving finer resolution over low-pressure settings.
Quick checklist
- ✓ Body size for your air demand (1/4" 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 GAFR300-08 filter-regulator as your air-prep needs grow.
Airtac B52-GAR Copper-Free Air Source Treatment Unit B52-GAR30008L FAQ
The GAR30008L regulates from 0.05 to 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 and has a 1/4in port. It is a lower-pressure type regulator with a fitted circular gauge.
The L type regulates only from 0.05 to 0.4 MPa (7-58 psi), unlike the standard S type which goes up to 0.9 MPa. This gives finer adjustment resolution across the low band, but it cannot reach setpoints above 0.4 MPa. If you need 0.5 MPa or higher, choose the S type instead.
