Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30008LC3
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR30008LC3 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 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-GR30008LC3
The GR30008LC3 is an AirTAC G-series compressed-air pressure regulator: it holds a steady downstream setpoint while upstream supply fluctuates. It regulates only - no filter, no bowl, no lubricator - so it sits after a filter in the air-preparation train. The 300 frame takes a 1/4 in PT tapered port as standard, this is the low-pressure type whose adjusting range tops out at 0.4 MPa, and it is supplied with an external round gauge scaled in bar plus a mounting bracket. Working temperature is -20 to 70 C.
This is a genuine AirTAC part. The G series covers 200/300/400/600 frames from 1/8 to 1 in ports, standard or low-pressure regulation, PT, G (BSPP) or NPT threads, and square embedded or external round gauges in MPa, psi or bar scales. Maximum working pressure is 1.0 MPa (145 psi). Because AirTAC publishes regulator flow as curves rather than a single rated number, we confirm the datasheet and sizing figures on request before you order.

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.

| GR300 | G-series pressure regulator, 300 body — sets the port range. |
|---|---|

| 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-GR30008LC3 Is Used
Packaging machine clamp cylinders
Set a moderate, stable pressure for the clamp-and-release cylinders on a carton-forming packer, where the low-pressure ceiling of 0.4 MPa is enough for gentle, repeatable clamping.
Woodshop spray booth
Regulate atomizing air to the finishing guns in a furniture spray booth, holding a repeatable setpoint so each coat lays down the same from gun to gun and shift to shift.
Bottling line gate actuators
Trim the supply to gate and stopper cylinders along a bottling conveyor so containers index smoothly without pressure surges upsetting the line timing.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30008LC3 the Right Regulator?
Pick the 300 frame when your circuit runs 1/4 in piping and sits between the smaller 200 frame (1/8-1/4 in) and the larger 400/600 frames; if your setpoint must exceed 0.4 MPa, step up to the standard GR type (0.05-0.9 MPa range). The LC3 suffix fixes the external round gauge in bar; square embedded gauges and psi or MPa scales are catalogue alternatives, as are G and NPT thread variants and J-coded no-bracket builds. Flow is published as curves, not a single rating, 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 - 0.4 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-GR30008LC3 FAQ
AirTAC publishes regulator flow as curves rather than one rated figure, so we do not quote a single number here. Send us your inlet pressure, setpoint and expected demand, and we will confirm the datasheet curve and check the sizing against your application on request.
It marks the low-pressure type: the adjusting range tops out at 0.4 MPa, where the standard GR type spans 0.05-0.9 MPa. This build also carries an external round gauge scaled in bar; square embedded gauges and MPa or psi scales are alternatives within the series.
