The AirTAC GR30010F2 AirTAC Air Pressure Regulator 3/8 in PT 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 GR30010F2 is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady at the setting you dial in, with no filtration or lubrication in the body. This 300-size unit is built around a PT3/8 (3/8 inch) port, and the F2 suffix means an embedded square pressure gauge is fitted, reading in psi. It is a standard-range regulator with an adjustment span of 0.05-0.9 MPa (7-130 psi), rated for a maximum inlet pressure of 1.0 MPa (145 psi), and it works across a wide -20 to 70 C temperature window. 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, 600) with ports from 1/8 to 1 inch, so you can step up or down as your line demands. Options include a low-pressure type (up to 0.4 MPa), a reverse/check valve, gauge scales in MPa, psi or bar, and G (BSPP) or NPT threads in place of the PT standard. Flow 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.

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 pressure to a bench or machine-mounted air cylinder on a press or forming station, so the stroke force stays repeatable shift after shift regardless of header swings.
Feed carton sealers, case packers and label-head cylinders on a packaging conveyor line at a fixed downstream pressure, protecting actuators from upstream surges in the shop-air main.
Regulate the supply to gripper and pick-and-place valves in a robotic assembly cell, where a steady setpoint keeps part handling gentle and consistent at the 3/8-inch drop.
Pick the size by the flow your circuit needs: 200, 300, 400 and 600 step up in both port size and capacity, and this 300 unit with its PT3/8 port sits in the middle of that range. Because AirTAC publishes GR flow only as curves, not as one rated number, send us your application details and we will confirm the right size before you order. Then settle the remaining decodable choices: gauge scale (this unit ships with a square psi gauge; MPa or bar scales and an external round gauge are alternatives), thread (PT is the standard here, with G and NPT available as order options), and whether you want the reverse/check valve or the low-pressure type added. A mounting bracket is included, and panel mounting is also possible.
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 regulator flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and the actuators you are feeding, and we will confirm the flow figures from the datasheet for your application on request.
The F2 suffix on GR30010F2 means an embedded square pressure gauge is fitted with a psi scale. If your team reads gauges in MPa or bar, those scales are available, and an external round gauge is an alternative option - just specify the scale when ordering.
