The AirTAC GR30010C2G AirTAC Air Pressure Regulator G3/8 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 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.
The GR30010C2G is an AirTAC GR-series air pressure regulator for compressed air, providing pressure regulation only - no filtration and no lubrication. This GR300 unit is built for 3/8 in ports with G (BSPP) thread, and the standard-type regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). The C2 suffix specifies an external round pressure gauge with a psi scale, and the unit ships with a mounting bracket; GR regulators are also panel-mountable. Operating temperature is -20 to 70 C, wider than the rest of the G family.
This is a genuine AirTAC part from the GR300 size, one of four sizes in the GR range (200/300/400/600) that step up in port size and flow capacity. Across the series you can choose thread type (PT standard, G or NPT to order), gauge style and scale, a low-pressure type limited to 0.4 MPa, a reverse/check valve, or a no-bracket version. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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.

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 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.
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.

Set a stable, reduced supply pressure to a small pneumatic press or clamping cylinder on a production cell, so the working force stays consistent shift after shift.
Regulate the air feeding cylinders and actuators on a packaging or cartoning line, protecting downstream components from swings in shop-air pressure.
Trim the supply pressure to a robot gripper circuit so delicate parts are held firmly without over-clamping, with the psi gauge giving a direct local readout.
Start with the port step: GR comes in 200/300/400/600 sizes with ports from 1/8 in to 1 in, and larger sizes carry more flow - match the size to the air demand of the circuit downstream. This unit is the 300 size with a 3/8 in G-threaded port. Next, pick the gauge: an embedded square gauge is standard, with an external round gauge optional, in MPa, psi or bar scales - the C2 code here selects the round gauge with a psi scale. Decide the thread standard (PT is the standard, G and NPT are order options), whether you need the low-pressure L type (up to 0.4 MPa) or the standard type, and whether the included bracket or panel mounting suits your installation. Because flow is published as curves and not a single rating, 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.
AirTAC publishes regulator flow as curves rather than a single rated figure, so we do not quote a l/min, SCFM or Cv number. Tell us your application and we will confirm the flow data from the datasheet on request before you order.
C selects the optional external round pressure gauge and 2 selects the psi scale. Without a gauge code the GR300 carries the embedded square gauge, and MPa (1) or bar (3) scales are the other choices.
