Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010LC1
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR30010LC1 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-GR30010LC1
The GR30010LC1 is an AirTAC G-series low-pressure air pressure regulator. The L in the code selects the low-pressure type, whose setting range tops out at 0.4 MPa - the right choice for circuits that must never see high pressure. This LC1 configuration is the 300 size with a PT3/8 port, an external round gauge on an MPa scale, and a mounting bracket included. It regulates only: no filter, no bowl and no lubricator.
This is a genuine AirTAC part. The GR series is offered in 200, 300, 400 and 600 sizes, standard or low-pressure types, PT/G/NPT threads, gauge or no gauge, bracket options and an optional check valve. We confirm flow and datasheet figures for this exact model 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.

| 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. |
| (blank) | Fixing bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.
Size Class

- GR400PT3/8" - PT1/2"
- 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-GR30010LC1 Is Used
Lab bench air supply
Give laboratory instruments, air bearings and pneumatic test rigs a gentle, clearly visible low pressure on the 3/8 in bench line, with the MPa gauge showing the setpoint at a glance.
Food packaging film handling
Regulate low-pressure air to packaging machine rollers, tension arms and web-guiding cylinders where product and film demand a soft, closely limited supply.
Instrument air take-off
Feed low-pressure pneumatic instruments and transducer lines from a plant air header, using the gauge to set and verify the reduced pressure on site.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010LC1 the Right Regulator?
The LC1 code is the 300 size with a 3/8 port - choose it when your line sits between the 1/4 in and 1/2 in steps and your setting pressure stays within the low-pressure type's range of up to 0.4 MPa. The C1 suffix brings an external round pressure gauge reading in MPa, so the outlet setting is visible at the machine; if you prefer psi or bar scales, or a square embedded gauge, other suffixes cover those. A mounting bracket is included on this variant. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options.
Flow is published as curves, not a single rating, so ask us to confirm sizing of the GR30010LC1 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 - 0.4 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-GR30010LC1 FAQ
AirTAC publishes GR-series flow as curves rather than one rated figure, so we do not state a number here. Share your line pressure, set pressure and air demand, and we will confirm the flow curve and datasheet for the GR30010LC1 on request.
Three things are decoded: L selects the low-pressure type, whose adjustment range tops out at 0.4 MPa instead of the standard type's 0.05-0.9 MPa; C fits an external round pressure gauge; and 1 sets that gauge scale to MPa. The 300 size carries a PT3/8 port and a bracket is included.
