The AirTAC GR30015F2G 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 GR30015F2G is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady at the setting you choose, and it does nothing else. There is no filter, no bowl and no lubricator in this unit - it is pure regulation. This 300-size configuration carries a G1/2 (BSPP) port, covers the standard regulation range of 0.05-0.9 MPa (7-130 psi), and ships with an embedded square pressure gauge scaled in psi. It handles a maximum inlet pressure of 1.0 MPa (145 psi) and operates from -20 to 70 C, a wider temperature window than the rest of the G-series family. A mounting bracket is included, and the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR family spans four sizes (200, 300, 400 and 600) with ports from 1/8 to 1 inch, optional G (BSPP) or NPT threads in place of the PT standard, gauge scales in MPa, psi or bar, a low-pressure type (L) limited to 0.4 MPa, and a reverse/check-valve option (K). Flow for this series is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures 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.
| GR300 | G-series pressure regulator, 300 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |
| (blank) | Fixing bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. 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.

On a workshop pneumatic press or clamping fixture, this regulator holds the working pressure the tooling was designed for, so cycle force stays repeatable from the shop air main.
On a cartoning or wrapping line, cylinders and grippers behave consistently when the branch feeding them is held at a fixed setting instead of drifting with the compressor.
At a take-off from the main plant air ring, this unit steps the header pressure down to the lower pressure a downstream cell or machine section needs.
Pick the GR size by the flow your line needs: 200, 300, 400 and 600 step up in port and capacity, and this 300 unit with its 1/2 in port sits in the middle of that ladder. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering. Choose the gauge scale you want to read - this unit carries the square gauge in psi; MPa and bar scales and an external round gauge are catalogue options. Set your thread deliberately: PT is the standard, while G (BSPP, fitted here) and NPT are options you order. The included bracket suits surface mounting, and the GR can also be panel-mounted. If your supply never exceeds 0.4 MPa, the low-pressure L type exists; this unit is the standard type with the full 0.05-0.9 MPa (7-130 psi) range.
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 curves, not as a single rated number, so we do not quote a figure here. Tell us your application and we will confirm the datasheet flow figures on request so you can size the unit correctly.
This unit has the embedded square gauge scaled in psi; MPa and bar scales, and an external round gauge, are catalogue options. PT is the standard thread, and this configuration is ordered with G (BSPP) 1/2 in ports - NPT is also available to order. A mounting bracket is included and the body is panel-mountable.
