The AirTAC GR30010F2TK 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 GR30010F2TK is an AirTAC GR-series air pressure regulator for compressed air, providing pressure regulation only - no filtration and no lubrication. This 300-size unit has a 3/8 in NPT port, a standard regulation range of 0.05-0.9 MPa (7-130 psi), and an embedded square gauge reading in psi (an external round gauge is optional). A reverse/check valve is fitted, and the unit includes a mounting bracket; GR regulators can also be panel-mounted.
This is a genuine AirTAC part from the GR300 series. The GR family spans four sizes (200/300/400/600) with stepped ports, thread options (PT standard, with G and NPT as orderable variants), gauge scale choices, and a low-pressure type option. Flow is published as curves rather than a single rated figure, so we confirm flow and datasheet details on request before you order.

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. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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 a stable, reduced pressure feeding a machine-tool clamping or workholding actuator, with the check valve helping preserve the downstream setting if supply pressure drops.
Regulate supply pressure to pneumatic cylinders on a packaging or cartoning line so sealing, pushing and egress motions run at the pressure the machine was set up for.
Feed a bench-mounted assembly or fastening station with regulated air, using the psi gauge to set the working pressure the tools and fixtures were specified for.
Pick the GR size and port step to match the air consumption of the circuit downstream - the four sizes (200/300/400/600) step up in port and capacity, and flow is published as curves rather than one rating, so ask us to confirm sizing against your application before ordering. Choose the gauge scale you want (MPa, psi or bar) and decide whether the fitted reverse/check valve suits your circuit - it holds the downstream setting if upstream pressure is lost. Thread is PT as standard on the series, with G (BSPP) and NPT available as order options; this unit is the NPT variant. A mounting bracket is included, and the regulator can also be panel-mounted.
Quick checklist
The reflux valve lets air flow back through the regulator, which is useful when downstream volume must vent quickly. 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 flow number. Send us your application's air consumption and we will confirm the correct size and flow behaviour from the datasheet before you order.
In the GR code, K means a reverse/check valve is fitted, which helps hold the downstream pressure setting if upstream supply is lost. F2 means the embedded square gauge is fitted with a psi scale; MPa and bar scales and an external round gauge are available as options.
