The AirTAC GR60025F2K AirTAC Air Pressure Regulator 1 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 PT1" 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 GR60025F2K is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady at the set point as upstream supply and air demand fluctuate. This is the 600 size, the largest in the GR line, with a 1 in PT (BSPT-type) port, so it suits the main air line of a plant or a high-consumption distribution header rather than a point-of-use drop. The code decodes as a standard-range regulator with an adjustment span of 0.05-0.9 MPa (7-130 psi), a maximum inlet pressure of 1.0 MPa (145 psi), an embedded square pressure gauge reading in psi, a built-in reverse (check) valve so downstream pressure cannot back-feed through the unit, and the mounting bracket included; GR bodies of this size are also panel-mountable. There is no filter, bowl or drain on any GR unit - regulation only.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and each size can be ordered with a choice of gauge scale, a low-pressure type, a reverse valve, or no gauge or bracket where the application calls for it. Thread options are PT as standard with G (BSPP) and NPT available as orderable variants. AirTAC publishes flow for the GR series as curves rather than a single rated figure, so send us your line pressure, set pressure and expected air demand and we will confirm the sizing against the datasheet 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.

| 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.

Dropping the 1 in main distribution line from the compressor receiver down to a stable working pressure for an entire production hall, with the check valve holding the header setting if the supply side is isolated.
Feeding a high-consumption conveyor line with large-bore cylinders and clamps, where the 600-size regulator keeps actuator pressure constant through simultaneous stroke cycles.
Panel-mounted regulation of a branch circuit feeding multiple downstream valves and process lines, with the psi-scaled square gauge giving operators a direct local set-point readout.
Start with the port and size step: the 600 size takes a 1 in port, and the right choice is the size whose flow curve covers your worst-case air consumption at your working pressure - not just the pipe diameter you happen to have. Set the adjustment range against your needs: this standard type covers 0.05-0.9 MPa (7-130 psi) downstream, with a maximum inlet of 1.0 MPa (145 psi). The F2 in the code gives you the embedded square gauge scaled in psi; if your panel reads in MPa or bar, the same unit can be ordered with scale 1 or 3, and an external round gauge is also available. The K code means a reverse (check) valve is fitted - useful when the downstream circuit must hold its set pressure if the upstream supply is removed; order without K if you do not want that behaviour. Thread is PT on this code, with G (BSPP) and NPT as orderable alternatives to match your piping standard, and the bracket is included (GR is also panel-mountable). One honest note on sizing: AirTAC publishes GR flow as curves, not a single rated number, so ask us to confirm the flow figure for your pressure conditions from 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 flow for the GR series as curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. The practical figure depends on your inlet pressure, set pressure and allowable pressure drop. Send us those three values and we will confirm the flow from the datasheet on request before you order.
F2 specifies the gauge: the embedded square pressure gauge scaled in psi (F is the square gauge, 2 is the psi scale; MPa and bar scales are orderable alternatives, and an external round gauge is also available). K means a reverse (check) valve is fitted, so downstream pressure cannot back-feed through the regulator. The rest of the code decodes as the 600 size with a 1 in PT port, standard pressure range, and bracket included.
