Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010N
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR30010N 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, ordered without a 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-GR30010N
The AirTAC GR30010N is a standard-type air pressure regulator from the G series, size 300, with a 3/8 in PT thread as the standard connection. It reduces and holds downstream pressure over an adjustment range of 0.05-0.9 MPa (7-130 psi), and does nothing else - no filtration, no bowl, no lubrication. Maximum working (inlet) pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part, supplied with a mounting bracket as standard; the N code means no pressure gauge is fitted. The GR family covers sizes 200, 300, 400 and 600, with panel-mounting possible and PT, G (BSPP) or NPT thread options in the catalogue. Flow appears as published curves rather than a single rating, so we confirm flow and datasheet figures 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.

| N | No pressure gauge (N). |

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-GR30010N Is Used
CNC machine tool air supply
On the air drop feeding a CNC machining center's tool-change and spindle-clamp circuit, the GR30010N holds a steady set pressure so clamp force and tool-release timing stay repeatable.
Palletizing line actuators
On a robotic palletizer's end-of-arm grippers and pusher cylinders, the regulator sets the working pressure for gentle carton handling on every cycle of the shift.
Pneumatic clamping fixtures
On a weld-shop fixture table, the regulator fixes the clamp-cylinder pressure so parts are held consistently across stations without over-squeezing thin sheet.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010N the Right Regulator?
For a standard GR regulator you choose size and port, thread style, gauge and mounting. This unit is size 300 with a 3/8 in PT port - move to size 400 or 600, or a larger port, when your circuit needs more flow capacity, or down to size 200 for compact drops. The N code omits the gauge; the catalogue offers an embedded square gauge or an external round gauge in MPa, psi or bar scales if you want local pressure indication. A bracket is included with this configuration, and the body is also panel-mountable. PT is the standard thread, with G and NPT available as catalogue options.
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-GR30010N FAQ
There is no single rated flow figure to quote: AirTAC publishes GR-series performance as flow curves. Share your supply pressure and consumption and we will confirm the right sizing from the datasheet on request.
The N code means this unit ships without a pressure gauge. If you want local indication, order a GR30010 with the gauge code instead: an embedded square gauge, or an external round gauge, each available in MPa, psi or bar scales.
