The AirTAC GR30010F2G AirTAC Air Pressure Regulator G3/8 (3/8 in) 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 GR30010F2G is an AirTAC GR-series air pressure regulator for compressed air: its single job is to hold a stable, adjustable downstream pressure from a varying supply. This 300-size unit carries a 3/8 in port with G (BSPP) thread, and the trailing 2 in the code selects the embedded square pressure gauge with a psi scale, so setpoints can be read directly at the panel. It is the standard (not low-pressure) type, rated for a maximum inlet pressure of 1.0 MPa (145 psi) with an adjustment range of 0.05-0.9 MPa (7-130 psi), and it operates in temperatures from -20 to 70 C - a wider window than the rest of the G-series families. As a pure regulator it contains no filter and no bowl, and no reverse/check valve is fitted in this code.
This is a genuine AirTAC part. The GR line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options that include an embedded square gauge (MPa, psi or bar scale) or an external round gauge, a low-pressure type limited to 0.4 MPa, a reverse/check valve, and PT, G or NPT threads; GR is also panel-mountable and this unit includes a mounting bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

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 bench pneumatic press or clamping fixture, the GR30010F2G holds the working pressure to the die so forming and staking strokes stay repeatable, with the psi-scale square gauge letting operators verify the setpoint at a glance.
On a cartoning or wrapping line, this regulator feeds cylinders and air-driven actuators from the plant main at a steady reduced pressure, protecting seals and keeping jaw, pusher and flap-fold motions consistent through the shift.
In a robotic pick-and-place cell, the GR30010F2G sets the supply pressure to gripper valves so delicate parts are held firmly without crushing, and the included bracket lets the unit mount neatly beside the cell's valve manifold.
Start with the port step: GR covers 1/8 in to 1 in across sizes 200-600, so match the 3/8 in G-thread connection of this GR300 to your supply line and the flow your circuit needs - larger sizes move more air. Then set the gauge: the embedded square gauge is standard and this code selects the psi scale, with MPa and bar scales available if your team reads metric. Choose the thread deliberately: PT is the standard, while G (as ordered here) and NPT are catalogue options specified at order time. Other decodable choices are the low-pressure L type (up to 0.4 MPa) and the K reverse/check valve; a mounting bracket is included and GR can also be panel-mounted. One honest note on sizing: flow is published as curves, not a single rating, so ask us to confirm the datasheet figures 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, not as a single rated figure, so we do not quote a Cv, l/min or SCFM number. Tell us your line size and air demand and we will confirm the datasheet flow-curve figures for this 3/8 in unit on request, before you order.
In GR30010F2G, the F selects the embedded square gauge and the 2 sets its scale to psi (MPa and bar scales are also available). The trailing G is the thread: G (BSPP) on a 3/8 in port. PT is the standard thread, and G or NPT are catalogue options you specify when ordering - they are specifications, not delivery terms.
