Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR40010JC1
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR40010JC1 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-GR40010JC1
GR40010JC1 is a genuine AirTAC G-series air pressure regulator in the GR400 size. It reduces and holds downstream pressure from a compressed-air supply, with a 0.05-0.9 MPa (7-130 psi) adjustment range and a 1.0 MPa (145 psi) maximum inlet pressure. The J in the code means it is supplied without a mounting bracket, and C1 fits the external round pressure gauge with an MPa scale. The 10 port position decodes to PT3/8. As a GR unit it is a regulator only: there is no filter bowl, no filtration element and no lubricator in this body.
The GR series is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch; PT is the standard thread and G (BSPP) or NPT are catalogue options to order. You can specify a square or round gauge in MPa, psi or bar scale, with or without a bracket, and with an optional reverse check valve (K). GR works from -20 to 70 C and has low pressure loss. Rated flow is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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. |

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-GR40010JC1 Is Used
Pneumatic clamp circuits on welding fixtures
Set and hold the working pressure feeding fixture clamps and grippers so parts stay held at the same force from cycle to cycle, isolated from swings in the shop-air header.
CNC machine-tool air supply
Regulate the branch feeding tool changers, chucks and air-blast nozzles on a machining centre, keeping actuator pressure stable as other machines on the main draw air.
Packaging line cylinder supply
Feed carton sealers and case packers at a controlled pressure so sealing cylinders stroke consistently across a shift instead of running off raw header pressure.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR40010JC1 the Right Regulator?
Step up to the GR400 with its 3/8 in port when your circuit sits above the GR300 class; if demand is lighter, GR200 or GR300 with a 1/4 in port may be the tighter match - we will confirm flow against the published curves on request. Set pressure is adjustable anywhere within 0.05-0.9 MPa (7-130 psi). The C1 code on this model selects the external round gauge with an MPa scale; the square (F) style and psi or bar scales are available as alternates. Thread is PT as standard, with G (BSPP) and NPT as options. J means no bracket is fitted, so order bracket hardware if you need a fixing plate, and choose a K variant if the line needs a reverse check valve.
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-GR40010JC1 FAQ
AirTAC publishes regulator flow as performance curves rather than a single rated figure, so we do not quote one l/min or SCFM number here. Send us your inlet pressure, set pressure and downstream demand and we will confirm the datasheet curve and sizing for this GR400 3/8 in unit on request before you order.
It breaks down as J = no mounting bracket fitted, C = external round pressure gauge, 1 = MPa scale. If you prefer the embedded square gauge, choose the F variant; psi (2) and bar (3) scale codes are also available. A trailing K on a GR code would add a reverse check valve, which this model does not carry.
