The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR40015JC1 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 PT1/2" 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.
The AirTAC GR40015JC1 is a compressed-air pressure regulator from the G series that holds a steady downstream pressure for the equipment fed from it. It filters nothing and lubricates nothing - regulation only. This configuration is the 400 size with PT1/2 threaded ports (PT is the standard thread; G and NPT are catalogue options), fitted with an external round pressure gauge scaled in MPa, with no bracket (J) and no reverse/check valve. Max inlet pressure is 1.0 MPa (145 psi) and the setting range is 0.05-0.9 MPa (7-130 psi); the regulator runs on compressed air only, from -20 to 70 C.
This is a genuine AirTAC part. The GR family is offered in 200/300/400/600 sizes for progressively larger ports and flow capacity, with square embedded or external round gauges, MPa/psi/bar scales, a low-pressure type up to 0.4 MPa, panel mounting, and a reverse/check valve option. AirTAC publishes pressure-loss and flow data as curves rather than a single rated figure, so we confirm the datasheet numbers 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.

Sets and holds the clamping pressure on a hydraulic-assist or air-over-oil press station fed from a plant air main, so fixture force stays repeatable shift after shift.
Regulates the supply pressure feeding pneumatic quarter-turn actuators on a process line, keeping actuator torque within the range the valve package was sized for.
Sits at the inlet of an independent zone on an automation machine, letting that module run at its own set pressure instead of the header pressure shared with the rest of the line.
Step up or down through the G series sizes (200/300/400/600) to match the pipe bore and the air demand of the line; the 400 size with 1/2-inch ports suits larger pneumatic circuits. Choose the gauge scale that matches your practice: MPa here, psi or bar on the JC2/JC3 variants. The standard thread is PT; specify G (BSPP) or T (NPT) if your piping uses those. This code carries J (no mounting bracket) and no K suffix, so no reverse/check valve is fitted - order a K variant if you want one.
Flow for GR regulators is published as curves, not a single rated number, so ask us to confirm sizing against your actual air demand before ordering.
Quick checklist
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 does not publish a single rated flow figure for the GR series; capacity is given as flow and pressure-loss curves. We will pull the datasheet curves for the GR400 size and confirm the figures against your line demand on request before you order.
J means no mounting bracket is included, C means an external round pressure gauge is fitted, and the final digit is the gauge scale - 1 for MPa here. Choose JC2 for a psi scale or JC3 for bar; all other details of the unit stay the same.
