Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20008C1
The AirTAC Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20008C1 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-GR20008C1
The B52-GR20008C1 is an AirTAC GR200 air pressure regulator in the copper-free (copper-prohibited) B52- build, which is the copper-free version of the base model GR20008C1. It regulates downstream pressure from compressed air only, with a 1/4 inch PT1/4 port, a standard adjustment range of 0.05-0.9 MPa (7-130 psi) and a maximum inlet pressure of 1.0 MPa (145 psi). This configuration is supplied with a round MPa gauge fitted and a mounting bracket included, and the GR body is also panel-mountable. The B52- prefix marks it for lines where copper and copper alloys are not permitted; confirm the exact material substitutions with us before ordering.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options include G (BSPP) or NPT threads, psi or bar gauge scales, a low-pressure type limited to 0.4 MPa, a reverse/check valve, and no-gauge or no-bracket variants. Regulator flow is published as curves rather than a single rated figure, 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.

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-GR20008C1 Is Used
Ammonia refrigeration plant control air
On an ammonia refrigeration installation, the copper-free B52- build lets this GR200 regulator drop plant air to the set pressure feeding solenoid valves and control actuators on the machinery-room panel, where copper and copper alloys are not permitted in the air circuit.
Battery cell assembly line actuator supply
On a battery cell assembly line, this regulator sets a stable supply pressure for the pneumatic cylinders that clamp and index electrode stacks at each station, with the round MPa gauge giving operators a local setpoint readout at the drop.
Electronics plant test-bench air regulation
At an electronics plant test bench, the GR200 holds the reduced pressure feeding air-operated fixtures and hold-down clamps during PCB functional testing, with the bracket allowing clean panel or frame mounting beside the bench manifold.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20008C1 the Right Regulator?
Start with the port step: this unit is size GR200 with a PT1/4 (1/4 inch) port; larger GR sizes (300/400/600) carry bigger ports and suit higher air demand, so match the size to the line rather than oversizing by habit. Set the working pressure inside the 0.05-0.9 MPa (7-130 psi) range; if your circuit runs below that, the GR low-pressure type (L) limited to 0.4 MPa is the decodable alternative. Choose the gauge scale (MPa, psi or bar) and thread family (PT standard, G/BSPP or NPT as order options), and decide whether you want the reverse/check valve (K) or a no-gauge (N) / no-bracket (J) variant. Flow for this family 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 - 0.9 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-GR20008C1 FAQ
AirTAC publishes GR regulator flow as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Tell us your line pressure, set pressure and air demand, and we will confirm the sizing from the datasheet on request before you order.
B52- marks AirTAC's copper-free (copper-prohibited) build of the base model GR20008C1, intended for lines where copper and copper alloys are not permitted, such as ammonia systems and some battery, electronics and chemical plants. The pressure, port and temperature specifications are shared with GR20008C1, but the specific material substitutions are not listed in our data, so confirm the exact details with us.
