Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010LC3
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR30010LC3 is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.4 MPa (7 - 58 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-GR30010LC3
The GR30010LC3 is an AirTAC G-series air pressure regulator: it controls downstream pressure only and contains no filter, no drain bowl and no lubricator. The 300 frame carries PT3/8 ports, and the L in the code marks the low-pressure type, whose setting range goes up to 0.4 MPa instead of the standard regulator's 0.05-0.9 MPa. The C3 suffix selects the external round pressure gauge with a bar scale, a mounting bracket is included, and the maximum working pressure is 1.0 MPa (145 psi) with a service temperature range of -20 to 70 C on compressed air.
This is a genuine AirTAC part. The GR series is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in PT (standard), G (BSPP) or NPT thread, with square or round gauges in MPa, psi or bar scales, and an optional reverse/check valve. Flow figures for this regulator are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing for your application.

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.

| L | Low-pressure type — 0.05 - 0.4 MPa (7 - 58 psi). Blank is standard, L is the low-pressure type. |

| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |

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.

- 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-GR30010LC3 Is Used
Bottling line air-knife drying
Feeds air knives that strip rinse water from bottles before labeling, with the low-pressure type holding a steady, gentle setpoint so delicate containers are dried without being disturbed.
Wood-finishing spray booth
Sets and holds the low atomizing-air pressure for spray guns on a furniture finishing line, keeping the finish consistent as operators move between booths on the same supply.
Web-tension brake control on a label press
Supplies the pneumatic tension brake on a narrow-web label press with a low, repeatable setpoint so the operator can trim tension between runs without pressure drift.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010LC3 the Right Regulator?
Step the frame up or down (200, 300, 400, 600) to match the port size your circuit needs; the 300 frame here gives 3/8 in PT ports. Choose the low-pressure L type when your setpoint must sit at or below 0.4 MPa; the standard GR300-10 covers 0.05-0.9 MPa. Pick the gauge style (embedded square or external round) and scale (MPa, psi or bar), specify G or NPT thread if PT does not suit the piping, and note that the regulator is bracket-mounted or panel-mountable with low pressure loss. Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against the 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 - 0.4 MPa (7 - 58 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-GR30010LC3 FAQ
AirTAC publishes regulator flow as characteristic curves rather than a single rated figure, so we do not quote one number here. Send us your inlet pressure, setpoint and expected air demand, and we will confirm the flow data from the datasheet on request and check the sizing for your application before you order.
It selects the external round pressure gauge with a bar scale. F would give the embedded square gauge instead, and the final scale digit can be 1 for MPa, 2 for psi or 3 for bar, so you can match the gauge to what your operators read.
