The AirTAC GR30010F3TK 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 GR30010F3TK is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady at the setting you choose, and it contains no filter and no lubricator. This 300-size unit is fitted with a 3/8 in NPT port. The regulation range is 0.05-0.9 MPa (7-130 psi), with a maximum inlet (working) pressure of 1.0 MPa (145 psi). The embedded square gauge reads in bar, and an external round gauge is available as an option. A reverse (check) valve is fitted, so downstream pressure is retained if the upstream supply is lost. A mounting bracket is included, and the body is also panel-mountable. Operating temperature is -20 to 70 C, wider than the rest of the G family.
This is a genuine AirTAC part. The GR line spans four sizes (200, 300, 400, 600) with ports from 1/8 to 1 inch, gauge scale choices of MPa, psi or bar, a low-pressure type option, and a reverse-valve option, so you can match the regulator to the line size and the reading your operators prefer. Flow is published as curves rather than a single rated figure; ask us and we will confirm the datasheet figures for your application 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. |
| 3 | Gauge scale: bar. 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 a stable, repeatable downstream pressure feeding a bench or C-frame pneumatic press, so each stroke clamps with the same force shift after shift. The check valve holds the setting if the shop air drops.
Regulate the supply to sealing jaws, pushers and clamp cylinders on a packaging line, where over-pressure distorts seals and under-pressure stalls the cycle. The bar-scale square gauge gives operators a clear local reading.
Feed a dedicated regulator ahead of a gripper or end-of-arm tooling manifold so delicate parts are handled at a set pressure independent of the main header. Panel mounting keeps the gauge visible at the cell.
Pick the GR size by line size and required flow: 200, 300, 400 and 600 step up in port and capacity, and this 300 model carries a 3/8 in NPT port. Set the downstream pressure anywhere in the 0.05-0.9 MPa (7-130 psi) range; the standard type covers normal duty, and a low-pressure type (L) exists for settings up to 0.4 MPa. Choose the gauge scale to suit your team: MPa, psi or bar (this unit is bar). Choose the thread to match your piping: PT is the standard, with G (BSPP) and NPT as catalogue options to order. Decide whether you want the reverse (check) valve fitted, as on this unit, to hold downstream pressure on supply loss. A mounting bracket is included and the unit is also panel-mountable.
One honest note on sizing: AirTAC publishes GR flow as curves, not as a single rated number, so we do not quote a flow figure here. Send us your line size and demand and we will confirm the sizing against the datasheet curves before you order.
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 GR regulator flow as performance curves, not as a single rated figure, so we do not quote a flow number here. Tell us your line size and air demand and we will confirm the sizing against the datasheet curves on request before you order.
Yes. Gauge scale is a real decode choice on GR regulators: scale 1 is MPa, scale 2 is psi and scale 3 is bar, so GR30010F3TK (scale 3) is the bar version. The embedded square gauge is standard and an external round gauge is available as an option; pick the model code with the scale your team reads.
