Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010JC2
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR30010JC2 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-GR30010JC2
The GR30010JC2 is an AirTAC G-series air pressure regulator: it reduces and holds downstream air pressure at a set value and does not filter or lubricate the air. This 300-size unit has a PT3/8 port, a 0.05-0.9 MPa (7-130 psi) setting range, and an external round gauge scaled in psi for direct reading in US units. The J suffix means no mounting bracket is supplied. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -20 to 70 C.
This is a genuine AirTAC part from the GR300 series, one of four sizes (200/300/400/600) that step up in port size and flow capacity. Square or round gauges in psi, MPa or bar scales, G (BSPP) and NPT thread options, and bracket or no-bracket versions are available across the series. Regulator flow is published as curves rather than a single rating, so tell us your application and we will confirm the figures from the datasheet 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.

| GR300 | G-series pressure regulator, 300 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.
Size Class

- GR400PT3/8" - PT1/2"
- GR600PT3/4" - PT1"
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-GR30010JC2 Is Used
US plant machine supply
Sets machine inlet pressure on equipment built to psi conventions, letting technicians read and adjust the setpoint without unit conversion.
Assembly tool circuits
Regulates the air feeding nutrunners, impact drivers and other assembly station tools so each station starts from a consistent supply pressure.
Service truck air supply
Drops the truck-mounted compressor output to a controlled pressure for pneumatic tools and jacks used at the job site.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010JC2 the Right Regulator?
The 300 size with a PT3/8 port serves mid-range flow; go to 400 or 600 as your circuit's air demand rises. The JC2 suffix gives you an external round gauge in psi and no mounting bracket - pick a bracketed GR300-10 if you panel-mount, or the F-code square-gauge versions for an embedded gauge. Thread is PT as the standard, with G (BSPP) and T (NPT) as orderable options. Regulator flow is published as curves, not a single rated figure, so 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-GR30010JC2 FAQ
No. AirTAC publishes regulator capacity as flow curves rather than a single rated number, so quoting one would be misleading. Send us your line pressure, set pressure and air consumption and we will confirm the sizing from the datasheet on request.
C selects the external round gauge instead of the embedded square gauge, and 2 sets its scale to psi. The J suffix also means no mounting bracket is supplied - bracket versions are available if you need one.
