Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010JC3
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR30010JC3 is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.9 MPa (7 - 130 psi) with PT3/8" ports, and ships with a pressure gauge. A regulator does not filter the air — put a GF filter upstream, or use a GFR filter regulator, when water and particulate must also be removed.

About the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010JC3
The AirTAC GR series is a pure air pressure regulator: it reduces and holds a stable downstream pressure from a compressed-air supply, with no filtration and no lubrication in the unit. This GR30010JC3 is the 300 size with a 3/8 in PT port (PT is the standard thread), supplied without a mounting bracket and fitted with an external round pressure gauge scaled in bar. It is a standard-pressure type with a maximum inlet of 1.0 MPa (145 psi), a regulation range of 0.05-0.9 MPa, and a working temperature of -20 to 70 C (non-freezing).
This is a genuine AirTAC part. The GR series spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and options include G (BSPP) or NPT threads, a low-pressure type limited to 0.4 MPa, a built-in reverse/check valve (code K), and bracket or panel mounting. Flow figures for the series are published as characteristic curves rather than a single rating, so we confirm the datasheet and sizing on request.

Specifications follow the official AirTAC G-series air-preparation data. Note the GR temperature range is -20 to +70 °C, wider than the other G-series units. A regulator has no bowl and no filter element, so there is no filtering grade. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |

| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |

Field order is size, port, type, bracket, gauge, gauge shape, scale, thread, reflux — a blank position takes the default. Example: GR300-08LNK is a 300 body, PT1/4", low-pressure type, no gauge, with reflux valve.

A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom rather than from a single rated figure.

Where the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010JC3 Is Used
Pneumatic clamping on a machining fixture
Set and hold the downstream pressure that closes clamps and vise cylinders on a milling or drilling fixture, keeping the holding force consistent from cycle to cycle.
Spray-gun atomizing pressure control on a paint line
Regulate the supply pressure feeding spray guns at a finishing booth so operators set a repeatable atomizing pressure for each coating batch.
Actuator supply on a packaging machine
Feed carton closers, pushers and diverters on a packaging line with a steady regulated pressure so cylinder actions stay uniform across the shift.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010JC3 the Right Regulator?
Size step: 200, 300, 400 and 600 raise port size and flow capacity together, so match this 300 size with its 3/8 in port to your line fittings, or step up a size for heavier demand. Gauge: the C in this code selects the external round gauge scaled in bar; the F code instead gives the embedded square gauge scaled in MPa. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options. The J means no mounting bracket is fitted - omit J if you need one - and add K if you want a reverse/check valve. Because flow is published as curves, not a single rated figure, ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" here)
- ✓ Standard 0.9 MPa or low-pressure 0.4 MPa
- ✓ Gauge fitted, or order N without
- ✓ Gauge shape C round / F square
- ✓ Scale MPa (1), psi (2) or bar (3)
- ✓ Reflux valve needed, order K
Installation & Maintenance Notes
- check Install downstream of the filter, following the airflow arrow.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Set pressure while air is flowing, then lock the knob.
- check Adjust within 0.05 - 0.9 MPa (7 - 130 psi) only.
- check Operating range -20 to +70 °C.
- check Panel-mount or use the fixing bracket; do not hang it on tubing.
Without a reflux valve, air cannot flow back through the regulator — order the K option if reverse flow is required. A regulator does not remove water or particulate; that is the filter's job.
Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010JC3 FAQ
AirTAC publishes GR-series flow as characteristic curves rather than a single rated figure, so we do not quote a number here. Tell us your inlet pressure and air demand and we will confirm the datasheet and sizing on request before you order.
It selects the gauge: C is the external round pressure gauge and the scale digit 3 means it reads in bar. The alternative F code gives the embedded square gauge scaled in MPa, so pick the scale your team works in.
