The AirTAC GR30015C2G AirTAC Air Pressure Regulator G1/2 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 GR30015C2G is an AirTAC GR-series air pressure regulator for compressed air, built for one job only: holding a stable downstream pressure. This 300-size unit is configured with a G1/2 (BSPP) port, the standard regulation range of 0.05-0.9 MPa (7-130 psi), and a round external gauge reading in psi so operators can set and monitor the working pressure at a glance. A mounting bracket is included, and the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, optional G (BSPP) or NPT threads, a low-pressure type (L) limited to 0.4 MPa, and gauge scales in MPa, psi or bar. Rated flow for the GR300 is published as a curve rather than a single figure; we confirm the datasheet and sizing 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.

| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 fixed working pressure for a bench or C-frame pneumatic press so forming and staking strokes stay repeatable, with the psi gauge readable at the machine.
Regulate the air feeding sealing jaws and clamp cylinders on a cartoning or wrapping line, keeping actuator force consistent across the shift.
Drop line pressure to the level a gripper or pick-and-place circuit needs, protecting delicate parts while the round gauge shows the set point in psi.
Size the GR by the flow your line needs: step up through 200, 300, 400 and 600 for larger ports and more air. Choose the gauge scale that matches your plant - MPa, psi (fitted here) or bar - and decide between the embedded square gauge or this external round gauge. Thread is G (BSPP) on this unit; PT is the standard and NPT is an order option. A low-pressure L type (up to 0.4 MPa) exists where the circuit cannot see full range.
Because flow is published as curves and not a single rated figure, ask us to confirm the GR300 curve against your air consumption before ordering. The bracket is included as standard on this code; a J-suffix variant omits it.
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 GR-series flow as performance curves rather than a single rated figure, so we do not quote one number. Tell us your air consumption and line conditions and we will confirm the GR300 curve and datasheet figures on request before you order.
The C2 in the code specifies an external round gauge with a psi scale. Gauge style (embedded square or external round) and scale (MPa, psi or bar) are real ordering choices on the GR family, so a different combination is available as a separate catalogue code.
