The AirTAC Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20008C3 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.
GR20008C3 is an AirTAC G-series air pressure regulator: regulation only, with no filter, no bowl and no lubricator. The 200 frame carries PT1/4 ports, and the C3 in the code specifies a round external gauge on a bar scale for plants that work in bar. Medium is compressed air.
This is a genuine AirTAC part. The GR series runs from size 200 to 600 with ports from 1/8 in to 1 in; PT is the standard thread, with G (BSPP) and NPT as catalogue options, and both standard and low-pressure (L) types are available. Maximum working pressure is 1.0 MPa (145 psi) and the GR setting range is 0.05-0.9 MPa (7-130 psi). Operating temperature is -20 to 70 C. Flow is published as curves, not a single rating, so we confirm flow and datasheet figures 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.

Regulates pilot air to quarter-turn pneumatic actuators on process valves, with the bar-scale gauge matching the plant's instrument readings.
Sets supply pressure on a laboratory or pilot-plant test bench plumbed in 1/4 in lines, where experiments call for repeatable, readable set points in bar.
Regulates air to the small fold, seal and eject cylinders on a cartoning or filling line, isolated from header pressure fluctuations.
Real, decodable choices on this series: size and port step (200/300/400/600; ports 1/8 in to 1 in - this unit is size 200 with 1/4 in PT ports); gauge style and scale (the round bar-scale gauge here, with psi and MPa options); thread (PT standard, G/BSPP or NPT to order); the low-pressure L type (up to 0.4 MPa) for low-pressure circuits; and the optional K check valve. Because GR flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application 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.
Flow for the GR series is published as curves, not as a single rated figure, so we do not state a rated number. Send us the application and required duty and we will confirm sizing and expected flow from the datasheet on request.
The C3 code fits the round external gauge with a bar scale, which suits plants and drawings that specify pressure in bar. Scale 1 gives MPa and scale 2 gives psi if your team reads in those units. The underlying regulator here is size 200 with 1/4 in PT ports.
