The AirTAC GR30010F2T AirTAC Air Pressure Regulator NPT3/8 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 GR30010F2T is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady at the setpoint you dial in, regardless of swings in the supply. This unit is the 300 size with a 3/8 in NPT port, the standard pressure type with a 0.05-0.9 MPa (7-130 psi) adjustment range, and it comes with the embedded square gauge fitted on a psi scale so the setting is readable at the machine. A mounting bracket is included, and as a GR unit it is also panel-mountable.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include G (BSPP) or NPT threads in place of the PT standard, a low-pressure type limited to 0.4 MPa, MPa or bar gauge scales, and a reverse/check valve. Because AirTAC publishes regulator flow as curves rather than a single rated figure, we confirm the sizing and 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.

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

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

| (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.

| Line order | Filter first, then regulator, then lubricator |
Set a stable, repeatable downstream pressure for a bench-mounted pneumatic press or clamping fixture, where a consistent setpoint keeps forming and joining operations predictable from cycle to cycle.
Feed a regulated branch to carton sealers, case packers or labelling heads on a packaging line, isolating those actuators from pressure dips caused by other equipment drawing on the same supply.
Drop the header pressure to a safe working level at the point of use on a factory air drop, protecting downstream tools, cylinders and valves from full line pressure.
Start with the size and port: the 300 body with its 3/8 in NPT port suits lines where the supply pipework is 3/8 in; if your flow demand sits near the top of what a 300 can pass, step up to the 400 rather than guessing. Set the gauge scale to match your team - this unit carries psi, but MPa and bar scales are orderable. Thread is NPT here; PT is the AirTAC standard and G (BSPP) is available if your fittings are metric/European. If your setpoint never exceeds 0.4 MPa, ask about the L low-pressure type; otherwise this standard unit covers 0.05-0.9 MPa.
One honest note on sizing: AirTAC publishes regulator flow as curves, not a single rated number, so there is no honest one-line flow figure to quote here. Tell us your application and we will confirm the sizing against the datasheet before you order.
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 rated flow number for this unit. Send us your application details and we will confirm the sizing against the datasheet on request before you order.
Yes. This unit carries the embedded square gauge on a psi scale, and the same gauge is available with MPa or bar scales. An external round gauge is also an option. Tell us which scale your team works in and we will decode the correct ordering code.
