Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010C1
The AirTAC Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010C1 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-GR30010C1
GR30010C1 is a genuine AirTAC G-series air pressure regulator: regulation only, with no filter, no bowl and no lubrication. This 300-size unit has 3/8 inch PT threads for larger mid-range circuits, a standard adjusting range of 0.05-0.9 MPa (7-130 psi), and a maximum inlet pressure of 1.0 MPa (145 psi). The C1 code specifies an external round pressure gauge on an MPa scale, so the set pressure is readable at the unit. Working temperature is -20 to 70 C.
This is a genuine AirTAC part in the 200 / 300 / 400 / 600 size range, with ports from 1/8 to 1 inch and optional G (BSPP) or NPT threads. The GR body is panel-mountable and takes an optional bracket. AirTAC states flow performance as curves rather than a single rated value, so we confirm exact flow and datasheet figures for your circuit 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.

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-GR30010C1 Is Used
Conveyor stopper and diverter cylinders
Set the operating pressure for stoppers, pushers and diverters along a conveyor line, with the round MPa gauge letting operators verify the setting at a glance.
OEM machine builder panels
Give a machine build a visible, adjustable pressure set point on the pneumatic panel, with the external round gauge mounted for easy reading during commissioning.
Laboratory test rigs
Regulate supply pressure to instrument air circuits on lab and test benches, where the MPa-scale gauge supports precise, repeatable pressure settings.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010C1 the Right Regulator?
Take the 300 size with PT3/8 ports when the branch line steps up from 1/4 inch work; 200 or 400/600 sizes cover smaller and larger demands. Thread is PT as standard; G (BSPP) and NPT are catalogue options. This C1 configuration includes the external round gauge on an MPa scale - if you prefer psi or bar scale, or the embedded square gauge instead, other GR codes carry those. A mounting bracket is included as standard.
Sizing against flow: AirTAC publishes GR300 capacity as curves, not as one rated number, so ask us to check the datasheet against your required flow 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-GR30010C1 FAQ
There is no single rated flow figure to quote: AirTAC publishes GR300 flow as characteristic curves, so any one number would be an approximation. Send us your line size and flow demand and we will confirm the correct values from the datasheet on request.
C specifies an external round pressure gauge (rather than AirTAC's embedded square gauge) and 1 sets its scale to MPa. If your standard is psi (scale 2) or bar (scale 3), or you want no gauge at all (N), there is a matching GR300 code - ask us for it.
