Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30008C3
The AirTAC Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30008C3 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 PT1/4" 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-GR30008C3
The AirTAC GR30008C3 is a genuine AirTAC G-series air pressure regulator that reduces and holds a stable downstream pressure from your compressed air supply, with no filtering or lubrication function. This size 300 unit has a PT1/4 port, and the C3 in the code means an external round pressure gauge on a bar scale is fitted. Regulation range is 0.05-0.9 MPa (7-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the operating temperature range is -20 to 70 C.
This is a genuine AirTAC part in the GR family, which spans sizes 200, 300, 400 and 600 with 1/8" to 1" ports, optional G (BSPP) or NPT threads, round or square gauges in MPa, psi or bar scales, a low-pressure type, and a bracket for mounting. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing for your application 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.

| C | Gauge shape: Round. C is round, F is square. |

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-GR30008C3 Is Used
Air cylinders on a packaging conveyor
Supplies pusher and divert cylinders on a packaging line at a set working pressure, with the bar-scale gauge letting maintenance staff read and reset the setting in the units their site uses.
Pilot supply for process control valves
Provides a regulated pilot-air pressure to pneumatic valve positioners and actuator pilots on a process skid, holding the reference pressure steady as plant supply fluctuates.
Workshop air drops for hand tools
Lets a maintenance workshop set a safe, repeatable pressure for impact wrenches, ratchets and air guns on a 1/4" drop, protecting tools and workpieces from over-pressure.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30008C3 the Right Regulator?
Pick the GR size (200/300/400/600) to match your port and the flow your circuit needs - larger sizes mean larger ports and more flow. The PT thread is the standard here; G (BSPP) and NPT versions are catalogue options to order. The gauge choice is a real decode decision: this code carries a round gauge reading in bar, while MPa and psi scales and the embedded square gauge are available on other codes. Flow in this series 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 (PT1/4" 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-GR30008C3 FAQ
AirTAC publishes regulator flow as performance curves rather than a single rated number, so we do not quote a fixed figure. Ask us to confirm the flow curves and datasheet for the GR30008C3 on request, and we will help you check it against your application before you order.
C stands for the external round pressure gauge and 3 is the bar scale, so this unit arrives set up for sites that work in bar. Other codes in the series give MPa or psi scales, or the embedded square gauge, so pick the code that matches the units your team reads.
