The AirTAC GR30010F1TK AirTAC Air Regulator 3/8 in NPT, MPa 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 GR30010F1TK is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady at the setting you dial in, and it contains no filter, no bowl and no lubricator. This 300-size unit is decoded with a 3/8 in NPT port, a standard regulation range of 0.05-0.9 MPa (7-130 psi), an embedded square gauge with MPa scale, and a reverse/check valve fitted so downstream pressure is held if the upstream supply drops. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -20 to 70 C, wider than the rest of the G family.
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, optional G (BSPP) or NPT threads in place of the PT standard, a low-pressure type limited to 0.4 MPa, gauge scale choices, and a panel-mountable body with bracket included. We do not quote a single rated flow figure because AirTAC publishes flow as curves; ask us and we will confirm the datasheet figures for your application on request.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.

| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |
| (blank) | Fixing bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 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 repeatable working pressure on a bench pneumatic press or clamping fixture, with the check valve keeping the set pressure at the cylinder if the main supply dips mid-cycle.
Feed a stable, adjusted pressure to the actuator circuits of a packaging or cartoning machine, with the MPa square gauge giving operators a clear local reading at the machine drop.
Regulate the air to sorter divertors and stopper cylinders on a conveyor line, holding a consistent downstream pressure so divert timing stays predictable across shifts.
Pick the GR size by the port and flow step your line needs: 200 through 600 map to larger ports and higher flow capacity, and this unit sits at 300 with a 3/8 in NPT port. Decide the gauge scale you want to read (MPa, psi or bar) and whether the embedded square gauge suits your panel or you prefer the optional external round gauge. Choose the thread for your plumbing: PT is the catalogue standard, with G (BSPP) and NPT as order options, and note the L-code low-pressure type if your circuit never exceeds 0.4 MPa. A reverse/check valve can be factory-fitted, as it is here, and the bracket is included for wall or panel mounting. Flow is published as curves rather than a single rating, so send us your application details and we will confirm sizing against the datasheet 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 regulator flow as performance curves, not as a single rated number, so we do not quote a flow figure here. Tell us your line pressure, set pressure and expected air demand, and we will confirm the datasheet curve and sizing for your application on request.
The K means a reverse/check valve is factory-fitted, so downstream pressure is retained if the upstream supply is lost. The F1 means the embedded square gauge is included with an MPa scale; psi or bar scales and an external round gauge are available as order options.
