Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20008LC3
The AirTAC Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20008LC3 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-GR20008LC3
The AirTAC GR20008LC3 is a compressed-air pressure regulator from the G series, sized 200 with 1/4 in. PT ports. It is the low-pressure (L) type, so its output is adjustable up to 0.4 MPa for circuits that must not run at full line pressure. It carries a round external pressure gauge with a bar scale, includes a mounting bracket, and is rated to 1.0 MPa (145 psi) maximum inlet pressure with an operating temperature of -20 to 70 C.
This is a genuine AirTAC part. The GR series is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in., a choice of gauge (round or square; MPa, psi or bar scale), a low-pressure option, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so we confirm datasheet 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.

| GR200 | G-series pressure regulator, 200 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| 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. |
| 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.
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-GR20008LC3 Is Used
Laboratory pneumatic bench supply
Regulate low-pressure air on a lab bench manifold driving small pneumatic test fixtures, with the bar-scale gauge matching local instrument readouts.
Pneumatic valve actuation panel
Feed pilot air to automated process valves on a skid, holding the actuator supply at a low set point below the plant main line.
Control-panel pilot air circuit
Supply pilot pressure to directional control valves and logic elements in a machine control panel where low regulated air is specified.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20008LC3 the Right Regulator?
This code fixes the key choices: size 200 with 1/4 in. PT ports, low-pressure (L) type with adjustment up to 0.4 MPa, and a round gauge on a bar scale. If your line needs higher set points, the standard GR type adjusts 0.05-0.9 MPa; if you prefer psi or MPa readout or a square gauge, those are separate order codes. PT thread is the standard; G (BSPP) and NPT are catalogue options, and a no-bracket (J) version exists.
For sizing, work from the port step: 200/1/4 in. suits light branch lines, while larger sizes carry more flow. Flow for 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 - 0.4 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-GR20008LC3 FAQ
AirTAC publishes GR series flow as curves rather than a single rated number, so there is no one figure we can quote. Tell us your inlet pressure and required downstream flow and we will confirm the sizing from the datasheet curves on request.
Yes. Gauge is an order choice on the GR series: round or square external gauges with MPa, psi or bar scales. This code is the round bar-scale version; the other combinations carry their own order codes, and the N code deletes the gauge entirely.
