The AirTAC GR40010F2G AirTAC Air Pressure Regulator, G3/8, psi Gauge 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 AirTAC GR40010F2G is a dedicated air pressure regulator: it controls downstream pressure only, with no filtration or lubrication function. This 400-size unit is fitted with a G3/8 (BSPP) port and carries the standard regulation range of 0.05-0.9 MPa (7-130 psi). The embedded square gauge reads in psi, an external round gauge is available as an option, and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -20 to 70 C, wider than the rest of the G-series, and a mounting bracket is included; the GR is also panel-mountable.
This is a genuine AirTAC part in the GR400 size family, which steps up in port size and flow capacity through the 200/300/400/600 range. Related codes in the series cover other thread options (PT standard, G and NPT to order), other gauge scales (MPa, psi or bar), a low-pressure type limited to 0.4 MPa, and a reverse/check valve option. Flow is published as curves rather than a single rating, so ask us to confirm the figures against your application before ordering.

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.

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

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 and hold the working pressure feeding a pneumatically actuated press or clamping fixture, so the tooling sees a stable, repeatable setting shift after shift.
Regulate the supply pressure to pick-and-place and sealing cylinders on a packaging line, keeping actuator speeds consistent as the compressor output fluctuates.
Drop the header pressure to a safe working level at an individual machine's air drop, protecting downstream valves and cylinders from full line pressure.
Choose the GR size by the port and flow your line needs: this 400-size unit takes a 3/8 in port, and larger sizes carry larger ports and more flow. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your air demand before ordering. Then pick your options: gauge scale (this code is a square gauge in psi; MPa and bar scales and an external round gauge are available), thread (PT is the standard, G and NPT are order options), the low-pressure L type if your setpoint stays at or below 0.4 MPa, and the K option if a reverse/check valve is wanted. A mounting bracket is included with this code.
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 number. Tell us your port size and air demand and we will confirm the flow from the datasheet curves for your conditions before you order.
The F2 in GR40010F2G specifies the embedded square gauge with a psi scale. The same regulator is available with MPa or bar scales, and an external round gauge is an option, so choose the scale your technicians read most easily.
